A project manager is responsible for delivering new software for their company.

The Dynamic Systems Development Method (DSDM) is an Agile framework that predates the Agile Manifesto and focuses on the full project lifecycle. It is particularly known for its " fixed " approach to constraints, which differs from traditional Waterfall methods.

Why Choice C is correct:

The DSDM Philosophy: Unlike traditional project management where the requirements (Functionality) are fixed and the Time/Cost are estimated, DSDM flips the triangle. In DSDM, Cost, Time, and Quality are fixed at the start of the project.

Variable Functionality: To meet these fixed constraints, DSDM allows the Functionality (Scope) to vary. This is achieved through the MoSCoW prioritization technique (Must have, Should have, Could have, and Won ' t have this time).

Prioritization: By fixing the time and budget, the team ensures that the most important functionality is delivered first, and less critical features are dropped if the fixed constraints are threatened.

Analysis of other options:

A, B, and D: These options include elements like " Integration, " " Risk, " " Outputs, " or " Features. " While these are components of general project management, they do not represent the four specific core variables governed by the DSDM " Fixed vs. Variable " model.

Integration and Risk (Option B) are management processes, not the constraints prioritized to meet project goals in this specific framework.

Requirements and Outputs (Option D) are synonyms for functionality, but they miss the " Quality " pillar which DSDM insists must never be compromised even when under pressure.

Key Concept: The Project Management Institute (PMI) and the Agile Practice Guide highlight DSDM for its focus on " fitness for business purpose " rather than " technical perfection. " By holding Cost, Time, and Quality constant (Choice C), DSDM provides a highly predictable delivery schedule for the business, using Functionality as the primary lever to manage project risk and deadlines.
