The first review should begin with a timeline. Record who gave the instruction, what task was agreed, who performed it, what information was available and when the damage occurred. Add the location, people present and immediate response.
Relevant records include contracts, service descriptions, orders, schedules, handover records, training records, qualifications, internal rules, emails and photographs. In an allegation of incompetence, earlier specific warnings, complaints or missing qualifications may matter. Such facts must be placed in their proper time and context.
For personal injury, medical findings and treatment records should form a separate group. For property damage, collect photographs, proof of ownership, repair invoices and value information separately. The damage documentation check helps organise the records.
