Start with the operating process
Before the script, triggers, inputs, target state, approvals and responsibilities must be understood. Otherwise an unclear manual workflow is simply reproduced faster.
- Starting and target state
- Permissions and approvals
- Responsibility for deviations
Safe and traceable execution
The automation should restrict inputs, check existing states and recognise whether a step has already been carried out. This keeps repetitions under control.
- Validation and safe defaults
- Idempotent or deliberately protected steps
- Clear exit and return values
Logging and error paths
Logs must explain which step ran with which result, without storing secrets or unnecessary personal data. Errors need an understandable classification and a defined next step.
- Time, action and target object
- Technical error with context
- Abort, retry or escalation path
Handover and long-term maintenance
Operations-ready automation is not tied to a single person. Documentation, tests, versioning and knowledge transfer enable the responsible team to develop it further safely.
- README and operating instructions
- Test cases for critical paths
- Versioning and controlled changes
Matching project evidence
November 2012 — December 2012
Joh. Berenberg Gossler
I migrated an existing batch script to PowerShell and enabled the internal team to automate server provisioning.
August 2011 — September 2011
Siemens AG
I automated Windows 7 administration with PowerShell and handed over the knowledge in practical support workshops.
June 2015 — December 2025
Dataport AöR
I supported business-critical specialist applications and took migrations through test, change and go-live into data-centre operations.
A script that only its author understands is an operational risk. I build automation that checks states, reports errors cleanly and can be handed over.
