Key principles of Agile Methodologies

The Agile Methodologies emphasize iterative development, customer collaboration, and responding to change. They prioritize working software over comprehensive documentation, individual interactions over processes, and customer collaboration over contract negotiation.

Critical Path in Project Management

The critical path is the longest sequence of activities in a project, determining the overall project duration. It's crucial as delaying any activity on the critical path delays the entire project completion.

Project Identification and Selection

Project identification involves recognizing potential projects, while selection prioritizes projects based on feasibility, alignment with organizational goals, and potential benefits.

Generic Competitive Strategies

Generic competitive strategies focus on achieving a competitive advantage in the marketplace. Cost leadership involves offering the lowest prices, differentiation provides unique value, and focus targets specific market segments.
