# 9.5 Manage Requirements
Requirements management is the process of **gathering**, documenting and **validating** requirements and **managing their implementation and change**. It is a process that runs **throughout the project lifecycle** and **relates to** other project management processes, such as **quality** and **change management**.
The Requirements Management Process **can be tailored** and customised to a project’s needs. It ==can be documented either in a Requirements Management Plan or in the Project Handbook==. Separate requirements documents are used to specify, categorise and prioritise the requirements. These can be **standalone** documents **or an annex to the Project Charter**.

## Inputs
- Project Initiation Request, [[Business Case]] and Project Charter
- [[B.1 Requirements Management Plan|Requirements Management Plan]]
- Project Stakeholder Matrix
## Guidelines
- A requirement is a **capability that a product or service must have** in order to satisfy a stakeholder’s need(s).
- **High-level requirements may also be referred to as business requirements**, and are usually initially specified in the Project Initiation Request, the [[Business Case]] and the Project Charter.
- Adding **further detail** to the requirements produces lower-level requirements. These can be described in a variety of formats (**e.g. text, use cases or user stories, models, business processes, sketches or graphics, etc.**) and are documented in various requirements artefacts.
- The agreed and **approved requirements** of all stakeholders constitute the **project’s baseline scope**.
- **Any change to the baselined requirements** should be made in accordance with the **change management process** described in the Change Management Plan.
- For **each identified requirement**, there should be a **corresponding test** to validate its acceptance. The **test should be documented** in the appropriate document (==Deliverable Acceptance Plan, Deliverable Acceptance Checklist or Quality Review Checklist==).
- Requirements should **describe the need not the solution** —non-ambiguous terms should be used and technology- or solution-oriented statements should be avoided.
- Even if requirements have been gathered before the project starts, it is still the **responsibility of the Project Manager (PM)** to **ensure they are managed properly**.
## Steps
1. **Specify** the requirements: Together with the project stakeholders, gather the project requirements and document them clearly in the **Requirements Artefacts**. Structure them by adding relevant **metadata**.
2. **Evaluate** the requirements: The project team assesses the feasibility, consistency and completeness of the requirements, and estimates the effort/costs needed to implement them. **The Project Manager (PM) balances the list of requirements against project constraints (budget, time, etc.)** and makes a proposal to the project stakeholders.
3. **Approve** the requirements: The Project Manager (PM) and key stakeholders—such as the Project Owner (PO) or Business Manager (BM)—**negotiate and agree** on the requirements for the project.
4. **Monitor the implementation** of requirements: The Project Manager (PM) continuously monitors the Project Core Team’s (PCT) implementation of the requirements, **adds new requirements and changes existing ones when needed**.
5. **Validate** the implemented requirements: When the requirements are implemented, User Representatives (URs) assess if the solution satisfies the initial business need. **Formal acceptance of the project deliverables** should comply with the Deliverables Acceptance process.
