A civic arena remodel team says schedule planning is unnecessary because 'everyone already knows opening night.' Why does schedule planning still matter?

Schedule planning turns a target date into sequenced work with dependencies, durations, and milestones the team can execute and control. A publicly known opening night is a constraint or goal, not a substitute for analyzing what must finish before what. Without that planning, resource conflicts and late path items surface too late to recover. CAPM fundamentals treat schedule planning as essential for realistic delivery, not optional paperwork when a date is already famous.
