No matter how experienced we are in our careers, projects almost always take much longer than we first imagine they will. In 1979, psychologists Daniel Kahneman and Amos Tversky named this phenomenon the planning fallacy.
A few factors contribute to the project time planning fallacy. For one, we tend to be overly optimistic during the estimation process. We usually plan for the best-case scenario, leaving little wiggle room for setbacks and obstacles. It makes us look more competent when we can promise an early deadline, but only if we can deliver.
Another aspect of the issue is our incomplete memory of prior events. We may need to remember how long previous tasks have taken us to complete, or we may attribute past issues to outside circumstances that will not come into play a second time. Often, we blame others for these hold-ups without taking accountability for our part in the delay.
Some might also be wishful thinking—we want a task to be done quickly, so we’d like to think it won’t take long. Ultimately, the result is the same: we deliver the project much later than our initial estimated completion time.
No one is entirely immune to the planning fallacy. Fortunately, once you’re aware of it, there are ways to improve the precision of your estimated completion time. Here are 5 tips to help you calculate a more accurate timeline for future projects.
