Project Manager Interview Questions

Project manager interview questions that explore the most important competencies or behaviors a project manager needs to be effective in the project manager job.

In addition to the project manager interview questions that assess your technical skills and experience you will be asked interview questions that explore your soft skills. These are the behaviors identified as necessary for survival and success as a project manager in today's tumultuous business environment.

The focus is on behavioral-based interview questions as they are used more and more in assessing suitability for a project manager job. The behavioral interview and how to answer behavioral questions is explained thoroughly at The Behavioral Interview Guide.

Go through these project manager interview questions and answer guidelines to help prepare for success in your project manager job search.

Give me an example of how you used your leadership skills to help your project team meet a difficult challenge.

An effective project manager needs to lead though setting goals and using the right methods to guide and influence the project team towards goal attainment. Good leaders enable team members to feel they have a real stake in the project and encourage them to participate in problem-solving and decision-making.

When answering project manager interview questions about leadership show how you understand the need to communicate and consult but are also aware that lots of talking and procrastination achieves nothing without deciding and taking action.

Effective project managers lead by example and are open and honest about the challenges they face. They recognize the important of collective team effort in achieving the desired results. They are able to identify and use the strengths of each team member and allocate roles and responsibilities accordingly.

This empowers team members to respond to the challenges that arise. Those that excel as project managers keep the project team motivated to give of their best to meet these challenges. They understand the appropriate management style to use with each team member at the different stages of team development. They know how to best utilize the competencies of the team and each team member to deal with challenges and problems.

Describe a time when your communication and interpersonal skills helped in dealing with difficult clients or team members.

After leadership, the ability to communicate effectively with people at all levels is regarded as the second most important project manager skill. Good project management requires clear communication about objectives, roles, responsibilities, performance, expectations and feedback. The project manager should be able to effectively influence and persuade clients and the team to ensure success. Explicit guidelines and expectations should be communicated to accomplish results.

project manager interview questions

When answering this question it is important to show how you are able to adapt your style of communication to the person you are dealing with. Empathy, understanding and self-awareness all play a role in doing this. The ability to communicate with different individuals on various levels with diverse project interests is important for successful project management. Every project team and every project is different, you must be able to adjust your style to their needs.

Included in communication skills is the ability to be enthusiastic about the shared goals and vision. Enthusiastic project managers are committed to their goals and express this through optimistic and confident communication.

Be aware of your communication style during the interview including your body language and other non-verbal signals.

Give an example of a win-win situation you negotiated

In all projects there are a number of stakeholders who all see their concerns and issues as the most important. Effective project management means responding by finding the best solutions that address the issues without compromising the other stakeholders or the overall project.

In your answer show how you are able to communicate essential information and workable alternatives in a way that gains acceptance. Your ability to understand the position of the other person and to focus on solutions rather than problems is key to effective negotiation on a project.

What was the most stressful aspect of your last project and how did you deal with it?

Very few projects stay on schedule, under budget and with no major problems. The ability to handle stressful situations is key to successful project management. Limited resources and time, changing demands and new circumstances all result in stress on the project manager.

Show how you are able to stay calm under pressure and plan to reduce stress focusing on aspects such as your people management, technology management, risk management and expectation management.

Tell me about a situation during a recent project when you had to adapt and manage change

Show that you can adjust effectively to meet changing demands and tasks. An effective project manager can quickly assess a new situation and adapt to it. The change management process is critical to the success of a project.

Each change needs to be properly defined, considered and approved before it is implemented. Focus on developing a plan for change that addresses change on both a process level and on a people level. Careful and well thought-out preparation of the stakeholders for change and the ability to overcome resistance are key to successful change management. Your answer should emphasize your ability to plan properly and thoroughly for change.

Prepare for project manager interview questions that explore these five essential competencies and show yourself to be a smart and effective project manager in your job interview.

Review the technical project manager interview questions that explore your experience on managing projects.

Useful interview questions and answers that explore your management style can be viewed here.

------------------------------------------

During the project management interview you will be asked interview questions that focus on your training and experience with the successful delivery of different projects.

You can also expect behavioral or competency-based questions that explore essential project manager skills such as team building and team management, planning and organizing, negotiation, problem-solving, leadership and adaptability.

Lets start with the likely project management interview questions that explore your experience on project delivery.

Tell us about your experience in managing different projects and how this can contribute to our position.

It is important to structure your interview answer because this is a multi-layered and fairly complex question. Start by explaining how you will answer the question. This keeps your answer on track and to the point.

"I will begin by giving you a short description of my last three projects. I will then detail the skills and abilities I developed as a result of each project and then demonstrate the value of these skills to this position."

You can then go on to provide a brief but concise summary of each project.

"I was the project manager for the XYZ project and this involved ..."

Then describe the skills you acquired during the project.

"I encountered a number of difficulties on this project that required an innovative approach. I used group problem solving sessions as one of these approaches. This worked well because it helped each team member to clarify their particular project role and responsibility and we were able to develop plans and realistic schedules that the whole project team contributed to ..."

Demonstrate how these skills will benefit the position and company.

"Projects now are faced with tighter budgets and fewer resources. This approach maximizes the available resources and keeps everyone focused and motivated for the duration of the project..."

Describe how you recently managed a diverse project team towards a common goal

project management interview

Focus on your ability to delegate in a fair and practical way, how you clearly defined project roles and responsibilities, kept personality clashes and conflict to a minimum and monitored and fed back to the project team. Outline your management style and why it worked.

Describe the most complex project you have managed from start to finish

Provide a comprehensive answer remembering to explain the project as you would to a client and not to somebody who has been involved in the project.

The more complex a project the more formal processes and techniques are needed to effectively manage the work. Explain the purpose, value and implementation of the most critical aspects of the project including managing the project work plan, the project schedule, the project risks, the project issues and closing the project.

Be enthusiastic about your accomplishments and specify how your experience will benefit the company. Point out where you made a difference on the project in terms of expenditure, quality, efficiency, customer satisfaction and business and organizational success.

Standard Project Management Interview Questions:

How do you determine realistic schedules for the project?

Explain your methods for resource allocation.

How do you manage suppliers?

How do you inform all the stakeholders of the progress of the project on a regular basis?

How do you monitor risks to the project and mitigate them?

What tools do you use to monitor and control projects?

What project management methodologies are you most familiar with?

What project software have you used?

What change management processes have you used to ensure that change is introduced properly?

What are the practices you follow for closing a project and meeting the conditions required to establish closure?

What specific training have you had that would be relevant to this project manager job?

Answer your interview questions in a calm and assertive tone. Take time to gather your thoughts before answering, it is a key project manager skill to be able to process the facts before responding!

Most project management candidates handle the questions designed to evaluate their technical proficiency well but tend to slip up on the project management interview questions that explore the behaviors or competencies required for a project manager position.

Behaviors or competencies are important because over 80 percent of candidates lose the job offer due to their inability to demonstrate the required project manager behaviors.

----------------------------

These project management interview questions explore your relevant experience and skills for the project manager job. The questions look at your understanding and approach to key project management responsibilities.

What are the necessary steps to successful project management?

What is your understanding and experience of the project manager role? Include aspects such as setting clear project objectives, building the project requirements, managing project cost, time, quality and scope. Refer in you answer to the specific steps you took to successfully manage and close a recent project.

What are the priorities to consider when planning a (your field) project?

Refer again to a recent project and outline your most important considerations in the planning stage. Time, scope and budget are the usual constraints to consider, but how did you allocate and integrate all the necessary inputs to meet the project objectives and plan for risk? 
The more in-detail the planning the greater the chances of project success. Highlight how each activity that is expected during the course of the project gets due attention.

In your experience what are the warning signs that your project may fail?

All project managers have had this experience. How did you pick up the warning signal (your monitoring and control processes and systems) and how did you manage it (corrective actions and implementing changes)?
Warning signals can include constantly changing specifications, lack of interest from executive management, incompetence on the project team, changes in the business environment and inadequate resources.
A project manager has to understand the uniqueness of each project and keep checking the project's contours against what they have learned on previous projects.

What are the most important considerations when recruiting and building an effective project team?

When answering this project manager interview question highlight how you not only consider the necessary experience and technical skills but look at critical roles and responsibilities and the dynamics between team members. How will the person fit in with organizational beliefs and goals? How will the person relate to the stakeholder group? A clear understanding of what is expected of each project member is essential.

Describe some innovative ways you have improved effectiveness on recent projects.

Solutions and improvements need to be found through the generation of ideas and alternatives in a creative, out-of the-box manner. Show your willingness to be creative and inventive with both the initiation of a new project and the components of an existing project.

What did you learn from your last project?

Focus on technical skills and knowledge as well as "soft" skills such as people and client management. Perhaps you learned something valuable about yourself as a project manager such as your willingness to adapt to a changing environment or your ability to mentor a team member. Highlight how you are able to learn from mistakes. What would you do differently knowing what you now know about the project?

What do you consider to be the most important project manager skills in terms of people management?

Leadership skills are key to successful project management. What are the methods you have used to guide and influence the project team towards reaching objectives. Good leaders make team members feel they have a real stake in the successful completion of the project. How do you structure your team, introduce and maintain good intra-team communication and improve team motivation and satisfaction?

-------------------------------------------------

Leadership interview questions focus on exploring and evaluating recognized leadership competencies. The questions are designed to assess whether the candidate has both leadership skills and leadership potential.

Management and leadership differ in a number of crucial ways. Management is a hands-on component of leadership - responsible for such functions as planning, organizing and controlling. Effective leadership is the ability to inspire followers to listen to and follow a vision. The ability to innovate and drive an organization or people towards new ideas and directions.

The ability to persuade and influence, demonstrate integrity, communicate and motivate, innovate and implement strategic vision, demonstrate drive and tenacity are all recognized leadership skills.

Leadership interview questions will require candidates to provide examples of how they have demonstrated these leadership competencies and are asked in the format of behavioral or competency-based interview questions.

How would your staff and colleagues describe your leadership style? Give me an example to support your answer.

The purpose of this question is to find out if the style is congruent with the organizational culture. The perceptive leader is able to adapt his or her style to fit the follower's, employee's and organizational needs.

What are the most important values and ethics you demonstrate as a leader? Give me an example of these in practice.

Integrity- being truthful and trustworthy and having conviction - is an essential leadership competency. The effective leader demonstrates values and ethics in personal behavior and integrates these values and ethics into organizational practices and activities. A good leader acts with the courage of his/her convictions. While leaders are open with their employees and model honesty, transparency and fairness, they do not violate confidences or divulge potentially harmful information.

Name some situations in which a leader may fail. Tell me about a time when you failed as a leader?

A number of factors can fall outside a leader's control such as the available skill pool in the organization, time constraints, the economic climate. If employees are lethargic and negatively orientated it can create a situation ripe for failure. In answering leadership interview questions that explore how you deal with difficult challenges focus on how you were able to analyze the setback and seek honest feedback to learn from failure. How you used the difficult situation to encourage constructive questioning of policies and practices. Show your ability to be resilient in the face of failure and to constantly work towards improvement.

What role does leadership play for a manager? How have you demonstrated this with your managers?

The leader's role is to communicate the strategic vision to management with clarity. To translate the vision into concrete direction and plans. To identify and communicate priorities, short term objectives, timelines, performance measures, clear accountabilities and performance agreements to management. To provide quality judgment and advice.

Tell me about an innovative solution you developed to a non-traditional problem.

Effective leaders promote change and innovation. Finding solutions to unique problems are facilitated by encouraging a constant information flow in all directions and emphasizing responsiveness to changing demands.

Tell me about a time when the going got really tough. How did you rally the staff and build morale?

Leaders build a sense of common purpose by promoting the organizational vision both internally and externally. They develop and implement effective communication strategies within the organization. Remove barriers to collaboration. Provide clear direction on priorities. Give clear and honest feedback to inspire trust.

What methods have you used to gain commitment from your team?

Leaders gain commitment by influencing and persuading the team to set objectives and buy into the process. They establish a spirit of cooperation and cohesion for goal attainment. They take the team into the performing phase as quickly as possible. Leaders encourage debate and ideas from all stakeholders. They inspire a commitment to success and excellence by demonstrating passionate personal commitment and promote a productive culture by valuing individuals and their contributions.

All leaders have to deal with conflict situations. Describe a recent disagreement or conflict you personally had to handle.

Leadership interview questions exploring how you handle conflict are looking at your ability to understand and respect different views. Demonstrate your ability to settle dispute by focusing on solving the problem taking into consideration the personalities involved. To evaluate the viability of different dispute resolution mechanisms available. To provide support and expertise to others. To negotiate compromise.

How have you influenced employees to follow your strategic vision for the organization?

Leaders develop ownership by involving employees in the decision-making and planning process. They provide resources to facilitate employee success and empower employees by devolving authority to get things done efficiently. Effective leaders develop processes that engage employees in achieving the strategic vision.

How have you encouraged learning and development of employees?

Learning happens at every opportunity. Your answer to leadership interview questions like this should demonstrate that effective leaders develop employees by mentoring, coaching and providing performance feedback on a daily basis. Leaders act as models for their employees but the most effective leaders not only teach by example they take a personal interest in the learning of others and serve as mentors. Additionally they manage learning throughout the organization by continually focusing attention on the learning agenda and providing the resources to facilitate it. Finally leaders monitor learning by getting regular feedback.

What was the most significant change you brought about in an organization?

Leaders can recognize new opportunities and anticipate long term opportunities. They determine new business directions for the organization. They are able to create enthusiasm and acceptance of the new vision or change and use the appropriate leadership style to inspire and guide employees to embrace change.

Thinks about what the concept of leadership means to you when preparing for leadership interview questions. Look back over your experiences and select insightful examples of how you have demonstrated the competencies associated with leadership.

Prepare for The Behavioral Interview

The Behavioral Interview is a proven and widely-used method of exploring a candidate's suitability for the position.

It goes beyond just looking at the candidate's educational and work history to determine the right fit, asking the candidate for specific examples of past behavior as they relate to the job requirements.

The behavioral interview is based on the logic that past behavior predicts future behavior.

If the job requires a person to be able to analyze and find solutions to problems the interviewer will ask the candidate to provide an example of when they previously displayed that behavior.

behavioral interview

"Tell me about a problem you uncovered in your previous job. What steps did you take to sort it out?"

It is often difficult to think of good examples within the time constraints and stressful context of a job interview.

Know which behaviors (sometimes referred to as competencies) are required in the position by reviewing the job description and requirements.

Looking back at your past jobs, prepare good examples using the following technique:

  • Describe the specific situation or task you were involved in

  • Detail the action and steps you took in the situation

  • Outline the results and outcome of your actions. What happened, what was accomplished, what did you learn

Listen carefully to the questions asked and, if need be, ask for further clarification. Answer with an appropriate and specific example. Often the Interviewer will ask follow-up questions to get more information,

" Tell me why you did that"

"Take me through your decision process"

"How did you feel about that"

so it is essential to have a complete, actual example to draw on.


Click on the list of Common Behavioral Questions & Answers above to help you frame your own examples.

Keep in mind that there are no right or wrong answers, it is an attempt to see how you behaved in a given situation. It is not possible to fabricate an example. The Interviewer's in-depth probing will quickly expose this.

Examples can be taken from any context as long as they clearly detail the required behavior.

Click on the specific job interview guides to review a list of behavioral questions relevant to each particular job with guidelines on how to prepare your best answers.

The World's Most Powerful People

"I love power. But it is as an artist that I love it. I love it as a musician loves his violin, to draw out its sounds and chords and harmonies." --Napoleon Bonaparte

Power has been called many things. The ultimate aphrodisiac. An absolute corrupter. A mistress. A violin. But its true nature remains elusive. After all, a head of state wields a very different sort of power than a religious figure. Can one really compare the influence of a journalist to that of a terrorist? And is power unexercised power at all?

In compiling our first ranking of the World's Most Powerful People we wrestled with these questions--and many more--before deciding to define power in four dimensions. First, we asked, does the person have influence over lots of other people? Pope Benedict XVI, ranked 11th on our list, is the spiritual leader of more than a billion souls, or about one-sixth of the world's population, while Wal-Mart ( WMT - news - people ) CEO Mike Duke (No. 8) is the largest private-sector employer in the United States.

In Pictures: The World's Most Powerful People

Then we assessed the financial resources controlled by these individuals. Are they relatively large compared with their peers? For heads of state we used GDP, while for CEOs, we looked at a composite ranking of market capitalization, profits, assets and revenues as reflected on our annual ranking of the World's 2000 Largest Companies. In certain instances, like New York Times Executive Editor Bill Keller (No. 51), we judged the resources at his disposal compared with others in the industry. For billionaires, like Bill Gates (No. 10), net worth was also a factor.

Next we determined if they are powerful in multiple spheres. There are only 67 slots on our list--one for every 100 million people on the planet--so being powerful in just one area is not enough to guarantee a spot. Our picks project their influence in myriad ways. Take Italy's colorful prime minister, Silvio Berlusconi (No. 12) who is a politician, a media monopolist and owner of soccer powerhouse A.C. Milan, or Oprah Winfrey (No. 45) who can manufacture a best-seller and an American President.

Lastly, we insisted that our choices actively use their power. Ingvar Kamprad, the 83-year-old entrepreneur behind Ikea and the richest man in Europe, was an early candidate for this list, but was excluded because he doesn't exercise his power. On the other hand, Russian autocrat Vladimir Putin (No. 3) scored points because he likes to throw his weight around by jailing oligarchs, invading neighboring countries and periodically cutting off Western Europe's supply of natural gas.

To calculate the final rankings, five Forbes senior editors ranked all of our candidates in each of these four dimensions of power. Those individual rankings were averaged into a composite score, which determined who placed above (or below) whom.

U.S. President Barack Obama emerged, unanimously, as the world's most powerful person, and by a wide margin. But there were a number of surprises. Former President George W. Bush didn't come close to making the final cut, while his predecessor in the Oval Office, Bill Clinton, ranks 31st, ahead of a number of sitting heads of government. Apple's ( AAPL - news - people ) Steve Jobs easily made the list, while Arnold Schwarzenegger, the movie star governor of California (which alone has an economy larger than Canada's) did not.

This ranking is intended to be the beginning of a conversation, not the final word. Is the Dalai Lama (No. 39) really more powerful than the president of France (No. 56)? Do despicable criminals like billionaire Mexican drug lord Joaquín Guzmán (No. 41) belong on this list at all? Who did we overlook? What did we get wrong? Join the conversation by commenting now.

Large Hadron Collider produces first proton collisions in Big Bang mission - Telegraph

Cern scientists have hailed the first proton collisions at the Large Hadron Collider as a "great achievement" Photo: PA

Scientists working at the European Organization for Nuclear Research (Cern), hailed the development as a "great achievement" and a major step towards mimicking the conditions that followed the Big Bang to unlock the secrets of the universe.

The low-energy collisions came unexpectedly after researchers managed for the first time to circulate two beams around the 27-kilometre (16.8 mile) tunnel 100m beneath the Franco-Swiss border for the first time on Monday.

Physicists working at the facility told how there was standing room only to watch the results and cheers erupted with the first collisions.

The world's largest machine was first launched in September 2008 amid an international fanfare which saw the world's media invited to the facility to make sense of the epic experiment.

But just nine days later, the £5bn LHC suffered a spectacular failure from a bad electrical connection. Fifty-three of 1,624 large superconducting magnets - some of them 50 feet long - were damaged and had to be replaced.

Just weeks ago, an element of comedy was introduced after it emerged that further problems had been caused by a small piece of baguette dropped by a passing bird which landed in a piece of equipment on the surface above the accelerator ring.

After 14 months of repairs, the giant machine was restarted on Friday evening and the first beam started circulating in a clockwise direction around the tunnel about 10pm.

By Monday, the operators were able to move onto the next stage of circulating two beams with the hope of generating a collision. Early in the afternoon, the beams crossed for the first time, then a second time later in the evening.

At present, the beams are being circulated at low-intensity to minimise any damage in the event of an accident. The true test will come as scientists provoke high-energy atom particle collisions and begin to analyse in earnest the fall out from the proton collisions in the months to come.

Ultimately, the collider aims to create conditions like they were one trillionth to two trillionths of a second after the Big Bang, which scientists think marked the creation of the universe billions of years ago. Physicists also hope the collider will help them see and understand other suspected phenomena, such as dark matter, antimatter and supersymmetry.

Cern's Director General Rolf Heuer said yesterday's collisions were actually the side effect of the quick advances being made by the LHC during its startup phase.

He said that the scientists would be proceeding cautiously, just a driver would with the first production model of a new car.

"We'll never accelerate this the first time with a kick-start to its maximum velocity," he said. "It's a great achievement to have come this far in so short a time. But we need to keep a sense of perspective – there's still much to do before we can start the LHC physics programme."

David Barney, a physicist working at Cern said: "It's quite amazing really, we never expected this to go so quickly. We're incredibly pleased, everything seems to be working excellently. The LHC hasn't actually accelerated particles yet - it hasn't made them go any faster than they were when they came into the tunnel.

"Cern intends to collide them at higher energy next week. It's going incredibly well and we don't really know what to expect next."

 

Facebook's value rises to $9.5bn

Social networking website Facebook's purported value has increased to $9.5bn (£5.8bn).

By James Quinn, US Business Editor

This is a near-50pc rise on its valuation in July when Russia's Digital Sky took a $100m stake.

At that point, Facebook, whose pre-IPO shares can be traded only privately between investors, was valued at $6.5bn.

The latest valuation is based on just 12 share sales between employees over the last two months, highlighting the illiquidity of the closed markets on which its shares trade.

According to SecondMarket, one of two private exchanges on which Facebook staff can trade shares with one another, shares are now selling for approximately $21 each, up 42pc from the $14.77 in July.

The value is backed up by SharesPost, the second exchange on which Facebook holdings can be traded, where bidders have pushed up offers to $20 in recent weeks.

Facebook's valuation is known for its wild swings. When Microsoft bought a 1.6pc stake for $240m in 2007, the website was valued at $15bn.

However, in the summer of 2008, when Facebook settled a lawsuit with some of founder Mark Zuckerberg's former Harvard classmates, the company valued itself at $3.7bn in court papers.

A more accurate valuation will not be known until Facebook's board decides to venture towards a stock market float.

Mona Lisa 'had eyebrows'

Mona Lisa, c.1503-6 (oil on panel); by Leonardo da Vinci
The art expert says he has uncovered a host of secrets about the Mona Lisa using a 240 megapixel camera Photo: BRIDGEMAN ART LIBRARY

Pascal Cotte said Leonardo built the painting up in layers, the last being a special glaze whose optical properties increased the illusion of a three-dimensional face. Above the glaze Leonardo painted details such as the eyebrows.

Cotte said: "That could explain why the eyebrows have disappeared – they have faded because of chemical reactions or they have been cleaned off."

He has uncovered a host of secrets about the Mona Lisa using a 240 megapixel camera. It can measure light so sensitively as to see through the top paint surface and uncover the layers below.

For example, infra-red imaging shows Leonardo moved the position of a finger on the left hand "to give a more relaxed position, consistent with the smile", Cotte said.

He said the Mona Lisa looked "totally different" 500 years ago, when it had a blue sky and the subject's skin had not yellowed.

The underlying layers of the face - painted using lead white and mercury vermillion - also show it was wider than the end result appears.

"The smile, the glance, the face were all wider," said Cotte.

But Leonardo did not change his mind half way through, he said. On top of the base layers the artist added a glazed shadowing layer to create a three dimensional effect.

"I do not say that he was successful, in reproducing a stereo-vision effect, but if you want to achieve that this is the best way to do it," said Cotte.

"But now it looks totally different to how he painted it. All the optical effects have disappeared."

He said that for Leonardo the Mona Lisa was "more than a painting, it was a challenge to reproduce real life".

Cotte's work is explained in an exhibition, The Secrets of the Mona Lisa, that opens at the Museum of Science and Industry in Manchester on Saturday.

Web Apps Suck



I know I'm going to get hate mail for this one… but here goes.

 

Recently I've been thinking a lot about user interfaces. I became enraged by the terrible user interface of Daz Studio, and then had the pleasure to use Motion. I have generally been using a large number of applications lately, and am currently creating my own fairly complex level editor for Chopper 2.

I could write many blog posts about all the different lessons I have been learning recently, but one in particular stands out.

 

Web apps suck. I'm talking about the web interfaces to the google suite, the photo editors, the facebook website. Apps that run in web browsers, any app that requires an internet connection to function at all, and does most of its work on a server somewhere.

 

Of course web apps have their uses. I don't think they should all just go away, it's nice to have a web app when nothing else is available. But what I'm saying here, is that compared to a native application, web apps are very much worse, for many reasons.

 

In the most simplistic sense; you need an internet connection, so your ability to access it is unreliable, you get presented with foreign looking – and behaving – buttons and sliders, and the service could go up in price, or simply disappear on you at any point.

 

But even if that is OK to you, and you like living on the edge, there is still the yucky user experience due to client-server communication. This is what I'm focusing on here.

 

The latency between action and response in web apps can be horrible, and this fundamentally comes down to the latency between the client and the server. A problem that I can't see any solution to in the next decade or two.

Currently, the internet can be a little slow at times. It doesn't matter if it's due to server overload, bad local wifi or network, slow or misconfigured databases or whatever… there are many, many reasons why a ping to an app server might take a while, and it always seems to take 'a while'.

 

Clicking a button in a local/native application, doing a minor computation, returning and displaying the results takes no time. I mean you simply cannot perceive the time it takes for the button to flash, simple data to get computed, and the result to be displayed. It's stupidly fast.

 

Clicking on any button in any web app could take any amount of time. Usually it's fast-ish. Sometimes it even appears to be as fast as a local app. But it's not, and sometimes it is far worse.

 

So every web app, no matter how much it tries to pretend to be a native app, is reliant on the connection to its server, and hence can't rely on some data being available. If you change some state, you can't guarantee the state change was valid until the server responds. If you scroll down a list, you can't guarantee that the new items being revealed will be available, or even still exist.

 

Most of the time it kind of works, kind of a bit slow, but OK. Every now and then someone turns a microwave on, and you wait. Every now and then someone changes a standard or a server config file, or you upgrade your browser, or the database overloads, and it all goes to shit. You might even lose all your data, despite your everything-in-triplicate local backups of your own machine's data.

 

This is Bad. It will always be bad. As technology improves, the technology that uses it also improves. And web based apps are a step behind. Web apps will always have higher latency, more interface issues and a less 'native' experience. They will always be a worse user experience than native apps, with less user control.

 

So why make web apps? Because it is easier. Because a developer made a website, and suddenly it turned into a web app. Because a developer wanted to make something simple for Windows and Mac and iPhone and Linux and couldn't afford to do it properly. Because a developer intends to inject advertising into the experience at a later date.

Most web apps don't even have a revenue model. Those ones are figuring out how to capture people so they can spam them or sell their details later.

 

Web apps suck. They are a poor substitute for a native app, and will continue to be so, for many reasons, for many years to come.

Busy In Heaven

Three men were standing in line to get into heaven one day. Apparently it had been a pretty busy day, though, so St. Peter had to tell the first one, "Heaven's getting pretty close to full today, and I've been asked to admit only people who have had particularly horrible deaths. So what's your story?"

The first man replies: "Well, for a while I've suspected my wife has been cheating on me, so today I came home early to try to catch her red-handed. As I came into my 25th floor apartment, I could tell something was wrong, but all my searching around didn't reveal where this other guy could have been hiding. Finally, I went out to the balcony, and sure enough, there was this man hanging off the railing, 25 floors above ground! By now I was really mad, so I started beating on him and kicking him, but wouldn't you know it, he wouldn't fall off. So finally I went back into my apartment and got a hammer and starting hammering on his fingers. Of course, he couldn't stand that for long, so he let go and fell-but even after 25 stories, he fell into the bushes, stunned but okay. I couldn't stand it anymore, so I ran into the kitchen, grabbed the fridge, and threw it over the edge where it landed on him, killing him instantly. But all the stress and anger got to me, and I had a heart attack and died there on the balchoy."

"That sounds like a pretty bad day to me," said Peter, and let the man in.

The second man comes up and Peter explains to him about heaven being full, and again asks for his story.

"It's been a very strange day. You see, I live on the 26th floor of my apartment building, and every morning I do my exercises out on my balcony. Well, this morning I must have slipped or something, because I fell over the edge. But I got lucky, and caught the railing of the balcony on the floor below me. I knew I couldn't hang on for very long, when suddenly this man burst out onto the balcony. I thought for sure I was saved, when he started beating on me and kicking me. I held on the best I could until he ran into the apartment and grabbed a hammer and started pounding on my hands. Finally I just let go, but again I got lucky and fell into the bushes below, stunned but all right. Just when I was thinking I was going to be okay, this refrigerator comes falling out of the sky and crushes me instantly, and now I'm here."

Once again, Peter had to concede that that sounded like a pretty horrible death.

The third man came to the front of the line, and St. Peter asked for his story.

"Picture this," says the third man, "I'm hiding naked inside a refrigerator..."
