Grade
A classification or level used to differentiate deliverables that serve the same purpose but are built to different quality specifications.

- Different grades can each be high quality if they meet their respective specifications.
- Choosing the grade is a requirements and business decision; quality management ensures conformance within that chosen grade.
- Upgrading or downgrading grade is a scope change and should follow change control.
Example
On an office renovation project, the team must pick carpet tiles. An economy line meets durability minimums, while a premium line offers thicker pile and longer wear at higher cost. Both options perform the same function; the difference between economy and premium is grade. After selection, quality control checks that the installed carpet meets the chosen grade's specifications.
