12 Types of Requirements Quality

 , updated on
Requirements quality is the degree to which requirements map to business goals and support project execution. The following are common criteria used to evaluate requirements quality:

1. Atomic

Each individual requirement refers to one thing and one thing only. In other words, requirements are broken down to their lowest level.

2. Correct

Requirements correctly meet business goals that are typically documented in a business case or business plan.

3. Traceable

Traceability refers to the ability to map between different types of requirements. This most commonly refers to the ability to map between the business case and functional requirements. Traceability is important for assessing the impact of changes and ensuring that functional requirements support business goals.

4. Complete

A complete requirement includes any details that are needed to fully constrain it.

5. Unambiguous

Requirements that aren't open to interpretation. This requires highly specific statements.

6. Consistent

Each requirement doesn't conflict with any other requirement. Requirements are also consistent with the target business and organization.

7. Verifiable

The requirement is verifiable. Common means of verifying a requirement include inspection, demonstration, measurement and analysis.

8. Feasible

Feasible requirements are possible given the constraints of the project and organization.

9. Design Independent

Requirements that don't place unjustified constraints on the design such as requesting that a favorite technology be used to implement a particular functionality. In many cases, technology specifications are included in the constraints section of a requirements document.

10. Prioritized

Each requirement is ranked in order of importance. This data is critical to project management activities such as project planning.

11. Concise

Free of extraneous information and wordage such as adjectives that aren't actionable.

12. Validated

Requirements that are reviewed both at as a high level strategy and at the line item level by stakeholders and subject matter experts.
