Which term is the formal name for the sequence of steps used by interior designers?

• A. Critical path
• B. Timeline
• C. Roadmap
• D. Methodology

Answer: (A)

The sequence of tasks that determines how long a project will take is called the critical path. In project planning, the critical path is the longest chain of dependent tasks, meaning each task must finish before the next one can start, and the total duration of these linked steps sets the minimum time needed to complete the project. In interior design, this could include stages like programming, space planning, design development, procurement, and installation, with each step depending on the completion of the previous one. Because these tasks have little to no slack, any delay on the critical path pushes out the overall timeline, making it the focal point for scheduling, resource allocation, and risk management.

The other terms describe different ideas. A timeline is a scheduled list of dates and milestones but doesn’t necessarily indicate the specific chain of dependent tasks that drives project duration. A roadmap offers a high-level strategic plan, not the detailed sequence that determines completion time. A methodology refers to the overall approach or set of methods used to carry out work, rather than the exact sequence of steps.
