Reasons Why Some Projects Fail

By Ben Ferris

A project team is sitting around the table looking frustrated because of a setback on their project.There are many different reasons why projects fail and if you stay in the project manager role for very long you are almost certain to come across some of them. It is good to be aware of the most common reasons of course, as this means that you have a better chance of avoiding them in the future.

Poor Scope Definition

The early days are vital in any project. This is when the scope is worked out and a clear idea of the scale of the work starts to fall into place. If this is done badly and the scope is left poorly defined then this is just storing up trouble for later on. All new project managers hear about the dangers of scope creep, which is when the amount of work included in the project just keeps on growing and growing. However, there is also the possibility that you will have underestimated the scope at the start and need to try and adjust as you go along. In either case, knowing what you are dealing with at the start is the only sensible way of driving on the project.

Overly Ambitious

It would be great to do the best project ever and solve everyone’s problems in one fell swoop but we also need to be realistic. There is a limit to what can be done in a single project and you might need to leave a few things on hold for future pieces of work. It might be that you have your work cut out to keep the ambitions of the project in check, as it could be that the stakeholders are the people who want you to fit everything which needs improved under this one umbrella.

Badly Written Plan

The project plan is basically the most important piece of information you will have throughout the project. It is something you will design in the early days and you will use it on a regular basis right until the end of the piece of work. This means that it is a hugely important document and one which you need to get right. The first time you need to come up with a project plan it will probably be a bit of a daunting prospect. It is not something which you will want to do in a hurry and you will want to take into account the feedback and suggestions you get from other people involved in the work before you try to get it signed off. The sign-off process means that it will not be subject to change control but that doesn’t mean that it has to be an immovable object. You still need to update it to reflect changes in the project, as long as you respect the change control process.

Lack of Resources

Even with the best will in the world a good project manager can’t be expected to do it all on their own. You will need the right resources If you are going to make a success of the role. In the first place, this means having a strong project team. It will be a big help if you have at least a couple of experienced project team members but on some of the less intense projects you might be able to train everyone up on what they need. Apart from the people side of things you also need to consider the other resources such as office space and equipment. Will the budget cover it all and is there time to get it all sorted out?

Unidentified Risks

Every project has risks but the big danger is in not being clear about them from the very beginning. If you know what a risk is all about then you can get a handle on it. On the other hand, if something crops up along the way then you might not have the chance to react and change your plans in time. Some new project managers don’t spend enough time thinking about risks and issues but it is definitely an area which needs a bit of thought put into it. You want as few unknowns floating around your project as possible, and the best way of achieving this is by getting everyone involved to think about all of the possible risks they can come up with. You then need to manage and monitor these risks throughout the entire project lifecycle, to see whether they are becoming more or less of a threat to your objectives.

    In my experience in addition to the reasons shown, lack of management momentum can influence project success as commitment from the business is essential.

      Very true!  Without support from the business and stakeholders your project is likely to fail.

    A common theme subtly woven into several of the reasons mentioned in this article seems to be that of communication or lack thereof.  One could argue that the primary role of a Project Manager is to facilitate communication – across organizational boundaries, amongst stakeholders, within the Project Team, with the investing Project Proponents, end users, and the list goes on.  The degree of deliberate and meaningful communication – written or verbal – profoundly affects project outcomes and ultimately determines success or failure.

        I agree Matt!  Communication is a big part of the project manager’s job.

    In my personal experience the most common cause of projects failing or delivering late and over budget stem from resourcing. This comes in many guises:
    Staff being Matrix managed so they have more then one boss and the project manager is the poor relation. So they keep being pulled off the project onto other work.Planning based on getting experienced and skilled staff, but when they are not available being given less qualified, or experienced staff who take longer to complete the tasks, and can make costly mistakes.Key resources not available at critical times in the project leaving the project on hold until they can be released from another project.A project team member working on more than one project, being given conflicting priorities, and PMs having to go back to the Project Director to determine which project takes priority.Overburdened Project team – stressed and demoralised. Leading to poorer performance and greater risk of staff going off on sick leave.Staff being asked to work overtime to complete tasks to get “back on track”. Which adds to burden on staff and also adds to the project costs.Too much reliance on one “expert” resource.Not being given the correct experienced staff to adequately test a change. So testing flawed.Poorly trained staff.Stessed and demoralised project manager.

    Hi Ben,

    One thing we recently noticed is that we over-estimated the technical knowledge of staff. We asked them to self-rate their technical knowledge and it was poor despite using the system for a long time. Small tweaks to their process resulted in terrible initial outcomes that group training didn’t address…a  lesson learned!

       Yes, I definitely see how that could be a problem!

  • Tee-Pee

    another key reason why projects fails is lack of communication.

      You are absolutely right, Tee-Pee!  Communication is critical in project management.  Thanks for mentioning this!

    Hello. I just joined the group.  I read through the comments to avoid being redundant. It’s up to the PM to have a “contract” with the customer, written or at least discussed, depending on the culture. This commits the customer to work with you when conditions change, e.g., scope creep or too much “admin” time required of the staff for non-project activities.  It’s also up to the PM to ensure that the total set of requirements includes reasonable evolution into the longer term. This lets you forecast long-term resource requirements that will be useful for your management to incorporate into future budgets.  This is particularly important in software development where you know the product will be evolved to meet future function and performance needs.
