Why do large IT projects fail?

One way or another, pretty much everything I’ve done and written about for the last few years has been based on a single premise and that is that IT can be done well and that projects can be delivered to specification, on time and on budget.

Delivering websites and IT systems via a small business has only emphasised – quite painfully at times – the thoughts and experience I had gained over the previous fourteen years working freelance on blue chip IT projects.

Broadly speaking, there are two reasons IT projects fail. One of those reasons is the people working on the project and the other is the way in which the project is organised and run. Many of my subsequent posts will be about the latter but, just briefly, I’d like to touch on the former.

I’ve been in IT for twenty-three years now and every successful project I’ve worked on has had a high proportion of The Right People. The most successful project I’ve worked on was exclusively staffed by people of that calibre.

At Meantime, we have struggled with recruitment. This is partly down to where we are based – the one downside of having our office in the Lake District – and partly down to the fact that IT is not a proper profession. There are no widely accepted formal qualifications – particularly around systems development – and so recruitment rests on the shaky platform of CVs and interviews.

Over the years we have always recruited with optimism and looked to bring out the best in people and, at times, we have been badly let down. We’ve now settled on a recruitment formula, which is as follows: I interview the candidate and Steve, our lead developer, gives them a technical interview. (Steve is also a pretty shrewd judge of character.) If we both like them and, crucially, even if they are not technically quite up to scratch, we ask them to carry out an online psychometric questionnaire, which is followed up by an interview with a trained assessor. We then receive a report and, whatever, the outcome, carry out a third interview.

As you can tell, just from that brief description, it’s a laborious and expensive process. However, experience has shown us that it’s far more cost effective to go down this route than to put the wrong person onto a project, given the long term damage this can do.

I’ll illustrate this point with one brief example. Several years ago we did a project that involved classes and terms. The developer in question, let’s call him Paul, was given a data model to work from and was walked through the use of that data model. At the time, he queried the way terms and classes were related and the database structure and process were explained in detail.

In the end, however, and without consulting any of his colleagues, Paul decided to do the work the way he thought best. The project went into user acceptance test and, as we moved towards the first change in term, it became apparent that Paul’s solution wouldn’t work. I don’t know whether Paul had realised this earlier, certainly he handed in his notice around the time the issue became apparent and left his ex-colleagues to put things right.

You can imagine the stress this put on the company. The issue was not the client’s fault, so there was no extra funding, and we had other projects in progress. Being a small business, we didn’t have any spare staff, so Steve, myself and another colleague, Mary, worked extra hours to turn this around.

The issue here was not so much that Paul had coded the solution wrongly, it was that he decided he knew better than the person (me!) who had talked to the client and written the specification. Even then, the problem was not so much that Paul had his own opinion, it was that he didn’t discuss his intention with anyone.

These days we recruit people whom our interviews and the psychometric test identify as team players, people with empathy for our clients, who want to deliver the best solution for them. Following this method, we’ve employed people who didn’t have our skill set or the right experience, who have turned out to make a brilliant contribution to our team. Ultimately, you can teach people skills and give them experience, what you can’t do – at least, not very easily – is change their nature.

OK, so that was a little less brief than I intended and the calibre of the people contributing to projects will certainly crop up again in my following blogs, but the point I’m making is that all of the other things I’m going to write about, those things that contribute to a project’s success, will not work without the right people.

Despite what they say, recruitment agencies don’t filter candidates, except in the very broadest terms. If a candidate’s skillset matches the job requirements, the agency will forward the CV. Many claim to have interviewed clients and given the percentages that agencies demand, one would expect they have spent serious time vetting them. However, in my experience at least, that is simply not the case.

It’s not enough to like someone at interview or to hire them because they pass a technical interview. For a project to succeed you need people who are team players, people who care about a project’s success, people who want to make your clients happy.

Last weekend, we carried out a data migration. Without being asked, the developer involved emailed me to say he’d be available if needed over the weekend and another colleague, who wasn’t directly involved, rang me over the weekend to check everything had gone to plan. When people take this level of interest, when they care about the outcomes, when people like this are working for you, then, with the right process and organisation, you can deliver successful IT projects.
