Definition:

Analysis paralysis occurs when an individual becomes so lost in the process of examining and evaluating various points of data or factors for a problem that they are unable to make a decision with it. Analysis paralysis can occur with many decisions, including investment decisions such as buying or selling securities. The inaction it causes can easily lead to losses in a portfolio or missed chances at larger profits.

Analysis Paralysis situation occurs when the team members strive to get a perfect answer, early in the inception phase before moving on. This delay in the project completion phase indicates that either the stakeholder or the team members fear to move forward into construction phase.
