What reporting is actually for
Reporting exists to answer three questions: did the attendance happen, was the periodic work done on schedule, and what happened to the issues you raised. Anything that does not serve one of those purposes is decoration. Keeping that in mind stops a reporting discussion from expanding into dashboards and scorecards that describe activity without telling you whether the building was actually cleaned and whether anybody would notice if it had not been.
It also matters most at review time. A year into an arrangement, the difference between a productive review and an argument is whether there is a record. With one, you can say a periodic task was completed twice rather than four times. Without it, both parties rely on recollection, and recollection reliably favours whoever is more confident about what they remember about what was and was not delivered during the year.
