Spreadsheet workflow
PLN System workflow
Task history
Often spread across files, chats, and personal notes.
Kept on the task with comments, files, plans, activity, and invoice actions.
Scheduling
Manual calendar updates and weak resource conflict visibility.
Survey planning tied to crews, equipment, vehicles, and absences.
Billing
Job details are copied into separate invoice files.
Invoice records use task pricing, contacts, activity, taxes, and payment status.
Field reporting
Arrives as messages and photos, then gets typed in by whoever is free.
Filed against the task from the phone, queued offline and synced when signal returns.
Equipment
Calibration dates in a second file nobody opens before dispatch.
Calibration, insurance, and inspection dates used during planning.
Control points
Coordinates in one surveyor's notebook or a folder of exports.
An organisation-wide register with condition notes and photographs.
Who can answer a question
Whoever owns the file, when they are at their desk.
Anyone with access, from the record itself.
Cost of a mistake
Silent: a stale copy stays plausible until someone acts on it.
Visible: there is one record, so a wrong value is wrong in one place.
