This document discusses project management methodologies, specifically the Waterfall and Agile approaches. It defines a project as a task with a beginning and end that creates value or change. Project management involves planning, organizing, motivating and controlling resources to meet goals. The Waterfall model involves sequential phases of requirements, design, implementation, testing etc. It works well for small, defined projects but can fail for larger ones due to inflexibility. Agile methods allow for more flexibility and adaptation.
