What is a good project management methodology?

A good project management methodology has these benefits:

- defines quality requirements: when quality requirements are defined in the plan and controlled throughout the project, the product meets customer expectations.

- provides adequate planning and co-ordination resources: proper planning and co-ordination of resources ensures deliverables are completed on time and on budget.

- provides an adequate definition of project roles and responsibilities: when project team members understand and accept their roles and responsibilities, they have more direction and make better decisions.

- provides adequate planning and monitoring for sudden, unexpected changes: a good project management methodology provides controls and techniques for dealing with change during the life of the project.

- defines the required outcomes: at the end, the required outcomes are met because the plan was built around them from the outset.
