| Example line item | Possible unit | What the description can clarify |
|---|---|---|
| Discovery and specification | milestone | Requirements and approved project outline |
| Design and implementation | milestone | Named pages, components or integrations |
| Launch support | package | Agreed deployment and handover work |
