Start with the technician's task
Observe how technicians find information during preparation, diagnosis, repair and verification. Ask what they know when they begin: a serial number, an equipment model, an error code, a symptom or a part number. Those entry points should shape navigation and search.
A useful mobile journey lets the technician establish applicability before following a procedure. Show the relevant product or configuration and make the document revision understandable. When a task depends on qualifications, prerequisites or safety conditions, keep that information prominent and connected to the instructions.
Documentation can support a task, but it does not replace required training, site procedures or professional judgment. Ease of access should never encourage a reader to skip conditions that determine whether a procedure is appropriate.
