IT Professional Skills

How to use this topic

The first four pages are about solving problems: the habits of a good IT professional, a troubleshooting method that works for any problem, asking good questions, and reading errors, logs and documentation. The next three are about writing and communicating: tickets and documentation, talking with users, and status updates. Then come working together and under pressure: handovers and on-call, major incidents, working safely on production, blameless postmortems and managing your time. The last five are about you as a professional: learning, ethics and privacy, security awareness, your career and your health.

The technical troubleshooting for each area is in its own topic (for example Troubleshooting Tools and Method and Troubleshooting Linux), service desk and incident processes are in IT Service Management, and using AI tools at work is in Using AI at Work. The technical side of on-call, incident response and postmortems is in Observability & SRE. These pages link there and focus on the skills that apply everywhere.

Four pages are tagged A+: documentation, communication, working safely on production and ethics match the Operational Procedures domain of CompTIA A+ Core 2. The other pages are untagged.
