Planning is one of the important phase like many said. It is basically the game plan if the team does not have a plan, there will chaos because there is no order which they can follow. The team will be walking blind and the project will not be done and/or there will be many errors done. The Planning phases helps distribute all task making it easier for the members to complete. Plans will always be altered throughout the project phase because it is the safe net. If an incident happens which disrupt the plan there should always be a back plan just in case where the team can switch gears without any problems.
