Learning outcomes
You will (1) apply skills during a supervised placement; (2) keep a professional log; (3) reflect on feedback.
28.1 Placement work
In her final year Rosa spends a supervised placement at Harbourview City Council. Her tasks include handling certificate tickets, reviewing TLS findings and supporting a supplier's integration. Owen assigns work with increasing responsibility, but she never holds administrator rights to the HSM or the internal CA, which remain with permanent staff. Rosa learns that professional practice includes knowing which actions belong to her role and asking before stepping outside it. She checks with Owen before any task that touches production during business hours, and records his decision. Her placement agreement lists permitted systems, which she rereads when unsure.
28.2 Professional log
Rosa keeps a daily log: tasks, decisions, evidence and questions. When a ticket asks her to "just disable certificate checking" for a broken integration, she logs the request, explains why disabling verification would expose the connection to interception and proposes installing the correct intermediate instead. The log becomes evidence for her placement assessment and a record if decisions are later questioned. It contains no secrets or citizen personal data. When she is uncertain, she writes the question in the log and raises it at the next daily check-in. Owen reviews the log weekly, initialling entries that involved production changes.
28.3 Reflecting on feedback
At mid-placement review, Owen praises Rosa's troubleshooting but notes that her change requests are too long for busy approvers. She rewrites them with a three-line summary at the top. Her tutor asks her to reflect on one mistake: she once restarted a service during business hours without telling the service desk. She writes what happened, its effect and what she now does. Reflection turns experience into lasting skill. She now posts a notice to the service desk before any restart, and her later change requests are approved faster. Her tutor notes that reflective writing is graded on honesty and specific changes, not on presenting a flawless placement.
Worked example
Rosa works under supervision without HSM or CA admin rights, refuses to disable certificate checking and reflects on feedback about change requests and communication.
Synthetic case. The placement is invented.
Errors and limits
Logs that include sensitive data become liabilities. Feedback without reflection rarely changes practice.
Exercises
- EX082 — Role limits. What rights did Rosa not hold during placement? Rubric: 3 = HSM and internal CA administrator rights;; 2 = both;; 1 = one;; 0 = none.
- EX083 — Disable checking. How did Rosa respond to a request to disable certificate checking? Rubric: 3 = explained interception risk and proposed installing correct intermediate;; 2 = both;; 1 = complied;; 0 = none.
- EX084 — Feedback change. What did Rosa change after Owen's feedback? Rubric: 3 = added a three-line summary to change requests;; 2 = summary;; 1 = vague;; 0 = none.
Synthesis
Field practice builds judgement about roles, records and communication, strengthened by honest reflection.
