10. Scope Management

Cost & Scope

What is Scope Management?

Scope management ensures the project includes all the work required — and only the work required — to complete the project successfully. It prevents scope creep, where unauthorized changes expand the project beyond its original boundaries.

Scope Management Process

1. Plan Scope Management — Document how scope will be defined, validated, and controlled
2. Collect Requirements — Gather stakeholder needs through interviews, surveys, workshops
3. Define Scope — Develop a detailed description of the project and product
4. Create WBS — Decompose deliverables into smaller, manageable components
5. Validate Scope — Formally accept completed deliverables with stakeholders
6. Control Scope — Monitor scope status and manage changes to the scope baseline

Requirements Collection

Techniques include:

• Interviews — One-on-one discussions with stakeholders
• Focus Groups — Moderated discussions with subject matter experts
• Surveys/Questionnaires — Broad data collection from many stakeholders
• Prototyping — Iterative mock-ups to refine requirements
• Observation — Watching users in their work environment

Work Breakdown Structure (WBS)

The WBS is a hierarchical decomposition of the total scope of work. Each descending level represents an increasingly detailed definition of the project work. The 100% Rule states that the WBS must capture all deliverables — nothing more, nothing less.

Scope Creep

Scope creep occurs when features or requirements are added without proper review, impacting budget and schedule. Prevention strategies include a clear scope statement, a formal change control process, stakeholder education, and strict prioritization.

Verification & Control

Scope verification is the formal acceptance of completed deliverables. Scope control monitors the status of scope and manages changes to the scope baseline, using variance analysis to detect deviations.
