A signature on a tablet is not proof of work — it confirms presence, not work. A useful proof-of-work record describes what was actually done, by whom, when, and in what condition, captured at the point of action with photos, readings, and condition notes so the office can act on the visit without phoning the field staff back. It also has to remain retrievable, complete, and tied to the right record months later when a complaint or audit lands.
Frequently asked questions
Is a signature on a tablet proof of work?
No. A timestamp and a signature confirm presence. They do not confirm the work. Real proof needs to describe the actual work performed — what was done, by whom, when, and in what condition, captured at the point of action.
What context should a proof-of-work record capture?
Photos, readings, and condition notes are what allow the office to act on the visit without phoning the field staff back. Capturing that context at the point of action is what makes the proof operationally useful.
What makes a proof-of-work record useful months later?
When a complaint or audit lands months after the visit, the proof needs to be retrievable, complete, and tied to the right record. Reviewability over time is what separates ceremonial proof from useful proof.
