Which type of project management prioritizes detailed upfront planning before execution?

The type of project management that prioritizes detailed upfront planning before execution is predictive project management. This approach involves creating comprehensive project plans that outline all aspects of the project, including scope, resources, timelines, and budgets, before the actual work begins. The predictive model, often referred to as the Waterfall method, emphasizes a linear progression where each phase needs to be completed before moving to the next one. This reliance on thorough initial planning helps to ensure that all requirements and potential risks are addressed at the outset, allowing for a structured and organized project execution.

In contrast, approaches like Agile and Scrum focus on adaptability and iterative progress rather than extensive upfront planning. They allow for changes in requirements and processes as the project evolves, making them less reliant on detailed initial plans. Lean methodology emphasizes efficiency and minimizing waste, which can sometimes lead to limited upfront planning as the focus is on continuous improvement and value delivery.
