If a project is consistently delayed, despite adequate resources, what principle might explain this, and what adjustment should be made?

Parkinson's Law likely explains the consistent delays in a project despite adequate resources. Parkinson's Law states that work expands to fill the time available for its completion. This means that even if a project has sufficient resources, if a long deadline is set, the work will often take the entire allotted time, regardless of whether it actually requires it. To adjust for this, the project manager should set shorter, more realistic deadlines for project milestones and tasks. Breaking the project into smaller, more manageable components with tighter deadlines creates a sense of urgency and encourages team members to focus on completing tasks efficiently. Regular progress reviews and adjustments to deadlines based on actual progress can also help to counteract the effects of Parkinson's Law. By actively managing time and setting clear expectations, the project can stay on track despite the tendency for work to expand.
