"It went well" is not an evaluation
You hand in your build. The marker reads, "It went well and the client was happy." What went well? How well? How do you know the client was happy?
An evaluation uses numbers, tests and quotes. It shows the work against the list of things it had to do.

Note
I can measure my finished work against each success criterion and show the evidence.
Key words
| Word | What it means |
|---|---|
| Success criterion | one thing the finished work must do, written so it can be measured |
| Measure | a number or a test result that shows how well a criterion was met |
| Target | the value a measure must reach for the criterion to be met |
| Evidence | something you made that shows what you did and what happened |
| User feedback | what the people who use the system say about it |
| Network | computers and devices joined together so they can share data |

This is practice
Important
The real Task 4b uses the real brief and its own success criteria, and the exam board decides how to show your evaluation. These examples are invented. Practise the method, then use it on the real criteria.
A criterion you can measure
A good criterion has a number or a clear yes or no. "The network is fast" cannot be measured. "A desk reaches the server with 0 percent loss" can.
Write each criterion with a measure and a target. Then you can say, in one word, whether it was met.
Worked example: measure each criterion
| Criterion | Measure | Target | Result | Evidence | Met? |
|---|---|---|---|---|---|
| Desks reach the server | Messages lost, in percent | 1 or less | 0 | Ping test T1, 30 of 30 desks | Met |
| Guests cannot reach staff | Number of staff devices a guest could reach | 0 | 0 | Test matrix, 5 of 5 blocked | Met |
| Backups restore | Restored files that match, in percent | 100 | 100 | Fingerprints before and after | Met |
| Main link can fail | Seconds without internet after unplugging the line | 30 or less | 45 | Test with the line unplugged | Not met |
| Staff find it easy | Staff who sign in first time | 5 of 5 | 4 of 5 | Notes from the acceptance test | Partly met |
