Learning outcomes

You will (1) present the capstone; (2) evaluate its value; (3) reflect on the programme.

30.1 Presentation

Tomás presents his capstone to Ms Okafor, an external assessor from industry, and Gareth. He explains the school's starting point, the changes made over the placement, the evidence of improvement and the health pack. He demonstrates the pack with synthetic data. The assessor asks what happens when Gareth is away; Tomás shows that the summary goes to the head teacher too and that the support contract covers emergencies. Gareth adds his own view of how the changes affected daily work at the school.

30.2 Evaluating value

To show the pack's value, Tomás reports Gareth's feedback after six weeks of use: the weekly review takes twenty minutes instead of thirty, and the pack caught one device that stopped logging within a day. He is careful not to overclaim: six weeks is short, and one catch is not a trend. The assessor values the honest evaluation and the fact that the school continues to use the tool after the placement ends. He suggests reviewing the pack's value again after a full school year.

30.3 Assessment criteria

The capstone is assessed on technical quality, security of the tool, evidence of value, documentation and professional practice. Tomás's documentation includes installation steps, a user guide, test results and a maintenance note. The assessor notes that the documentation would let another technician maintain the tool, which is an important criterion for work in organisations with few staff, where a tool understood only by its author soon becomes a liability. The assessor also checks that tests are included and pass. Marks are moderated.

30.4 Reflection on the programme

Tomás reflects on three years. He started thinking security meant tools and rules; he finishes understanding that it also means inventories, people, suppliers, routines and honest evidence. He notes that small, steady improvements at Ridgeway, such as termly account reviews and drift detection, mattered as much as the big segmentation change. He plans to work as a network technologist in education, where he has seen how much difference careful, practical work can make. Ms Okafor adds the reflection to the course's examples for future students.

Worked example

The capstone passes with commendation for honest evaluation and maintainable documentation.

Synthetic case. The assessment is synthetic.

Errors and limits

Claiming broad benefits from a few weeks' use overstates a tool's value.

Exercises

EX088 — Absence plan. How does the health pack handle Gareth's absence? Rubric: 3 = summary to head teacher, support contract;; 2 = shared;; 1 = vague;; 0 = none.
EX089 — Measured value. Give two measured benefits after six weeks. Rubric: 3 = review 30 to 20 minutes, one logging failure caught;; 2 = one;; 1 = vague;; 0 = none.
EX090 — Maintainability criterion. Why is maintainability important in small organisations? Rubric: 3 = tool understood only by author becomes a liability;; 2 = few staff;; 1 = vague;; 0 = none.

Synthesis

The technologist route ends with practical, evidenced improvements and a maintainable contribution.
