Overview of Project Management Methodologies and Approaches
While there are numerous project management methodologies and approaches, they can be broadly categorized into two main types: traditional (also known as waterfall) methodologies and agile methodologies. Traditional methodologies follow a linear, sequential approach to project management, with each phase of the project being completed before moving on to the next. Agile methodologies, on the other hand, emphasize flexibility, collaboration, and iterative progress, allowing project teams to adapt to change and deliver value incrementally.
Some of the most popular project management methodologies and approaches include:
- Waterfall
- Agile
- Scrum
- Kanban
- Lean
- Six Sigma
- PRINCE2
- Critical Path Method (CPM)
- Critical Chain Project Management (CCPM)
