If you’ve managed projects for any length of time, you’ve probably noticed this pattern: the first 80% of a task comes together quickly, but that final 20% — reviews, approvals, edge cases, stakeholder sign-off — drags on and often eats up half the total timeline.
A few reasons this happens:
• Hidden dependencies surface late. Early progress feels fast because you’re doing visible work. The final stretch often involves waiting on others — approvals, feedback loops, or cross-functional sign-off — which is harder to control.
• Perfectionism creeps in near the finish line. Once something is “almost done,” there’s a temptation to keep refining it rather than shipping.
• Scope creep hides in the details. Small asks (“can we just tweak this one thing”) pile up right before delivery.
