Ace the CAPM Adventure 2026 – Your Project Management Power-Up!

Sequential phases in project management refers to the concept that each individual phase must be completed before moving onto the next phase. This ensures that the project progresses in a logical and organized manner. Option A is incorrect because completing phases at the same time would lead to complications and overlapping tasks. Option B is incorrect because unclear requirements can delay or disrupt the project, but it does not involve the dependency of phases. Option D is incorrect because planned phases are typically executed in order to complete the project successfully. Therefore, option C is the most fitting explanation for the term 'sequential phases' in project management.
