Continued business justification
Hopefully, we only start projects that are justifiable. However, that’s not enough, because things change and a project that used to be justifiable may lose its justification along the way. Unfortunately, most of these projects are continued without paying attention to this issue, sometimes because of being blind to it, and sometimes because of being victims of the sunk cost fallacy.
We must frequently check the justification of the project. A good way is to have certain, predefined, frequent points when we stop and ask whether or not we should continue the project based on the latest information. Even if your project doesn’t lose its justification and you continue it, these gates remind you of why you are doing the project and help keep everything aligned with the goals.
