The relationship between quality management, project requirements, and the Work Breakdown Structure (WBS) is foundational to successful project planning and execution. Here's how they interconnect:
🔹 1. Project Requirements
These are the needs and expectations of stakeholders that the project must fulfill. They include:
- Functional requirements (what the product/service must do)
- Non-functional requirements (performance, usability, etc.)
- Regulatory or compliance requirements
Why they matter: Requirements define the scope of the project and serve as the baseline for planning, execution, and validation.
🔹 2. Work Breakdown Structure (WBS)
The WBS is a hierarchical decomposition of the total scope of work to accomplish the project objectives and create the deliverables.
- It breaks down the project into manageable sections (work packages).
- Each element in the WBS should be traceable back to one or more project requirements.
Why it matters: The WBS ensures that all requirements are addressed and provides a structure for assigning responsibilities, estimating costs, and scheduling.
🔹 3. Quality Management
This involves the processes and activities that determine quality policies, objectives, and responsibilities. It includes:
- Quality Planning: Defining quality standards and how they will be achieved.
- Quality Assurance: Ensuring processes are followed.
- Quality Control: Monitoring specific project results to ensure they meet the standards.
Why it matters: Quality management ensures that the deliverables meet the project requirements and stakeholder expectations.
🔄 How They Interrelate
| Element | Role | Connection |
|---|---|---|
| Requirements | Define what must be delivered | Basis for WBS and quality standards |
| WBS | Organizes work to meet requirements | Ensures all requirements are covered |
| Quality Management | Ensures deliverables meet requirements | Uses requirements and WBS to define quality criteria and control points |
✅ Example
If a requirement is to build a mobile app with a secure login:
- The WBS will include a work package for "Develop secure login module."
- Quality planning will define what "secure" means (e.g., encryption standards).
- Quality control will test the login module against those standards.
