Three universal truths for why projects are not completed on time

Finishing a project on time is a difficult achievement in the workplace and at home. In last week’s post “Uncluttered project planning,” I discussed ways to avoid missing deadlines when you’re in charge of the project. However, we’re not always the ones calling the shots.

In fact, even when we think we’re in charge of a project, we often are not. When we have to rely on others to supply information, supplies, or support, timelines (and budgets) can quickly be extended. After years of working across multiple professions and with clients, I have identified where projects typically go awry. From page 200 of Unclutter Your Life in One Week:

These are the universal truths for why projects are not completed on time:

  • Clients are never as prepared as they say they will be.
  • Clients always change their mind.
  • People always underestimate the amount of time it will take to do something.

(The word clients in this list can easily be substituted with bosses, co-workers and also you.)

Clients are never as prepared as they say they will be. For most people, working on a project is more fun than planning it. As a result, clients don’t think through the entire process and its results before contacting a vendor. Putting in the research, collecting data, identifying the goal of the project, and envisioning it through to its completion before contacting a vendor will help enormously to preserve a timeline.

Clients always change their mind. I think it’s important for a project to have flexibility, but changing the scope of a project will extend timelines and/or costs. You need to be prepared for these changes and ready for when they happen. You can reduce the impact and costs of these changes simply by having a single decision-making liaison between the client and vendor. If a client or vendor is being contacted by more than one person, there are too many cooks in the kitchen. One person should act as the filter on both ends of a relationship to make sure that only approved changes that relate to the final outcome of the project are communicated.

People always underestimate the amount of time it will take to do something. Even though I have timed myself enough to know how long it actually takes me to do something, I still think I work faster than I do. We all think this way. In our minds, we have speed of pumas. Avoid this project pitfall by using the following:

A good rule of thumb is to double everything up to a day. If you think something will take you two hours, plan for it to take four. If you think something will take you eight hours, plan for it to take sixteen. After eight hours, the double rule stops being as accurate. For projects that I estimate will take between one and five days, I just tag on an additional day. If someone says it will take him two weeks to complete a portion of the project, I add three additional days into the schedule.

Your project’s timeline can be preserved or closely achieved with proper planning, organizing, improved communication, and realistic expectations for work completion. Remember the three universal truths for why projects are not completed on time, and do your best to avoid them.
