Missing a milestone can mean failure but it does not mean that the project is over. Many times, if a project is massive for a company, the can face complex obstacles and may fail a milestone in the way, but it can be taken as an opportunity to re-evaluate the plan, consider possible alternatives, and ultimately improve the process. Even though it can cause lots of stress, the team should be prepared to face the risks of the project and have backup plans.

It can also happen that missing a milestone can give the hint that the project is not going in the right direction and that it needs to be completely redirected. Either case, the team should take the opportunity to lear, and grow.
