Every workspace accumulates. A quarterly pass keeps it fast, and keeps new joiners from drowning.
Views are cheap to create, so people create them. A sheet with fourteen views has a switcher nobody reads.
Delete the ones nobody opens. A view holds no data — deleting one never loses a record.
An unmaintained field is worse than a missing one: half-filled, quietly wrong, and everyone scrolls past it.
For each field ask: is anyone filling this in, and does anything depend on it? If both are no, remove it.
Old records slow big views and bury current work. Either filter them out of everyday views, or move genuinely finished projects to an archive sheet.
If a view feels slow, this is usually the reason — see Something is slow or not working.
Twice a year, walk Settings → Users:
Open the list and ask what each is for. Switch off the ones that no longer serve anyone — an automation firing into a channel nobody reads is noise everyone has learned to ignore.
Check connections for amber dots at the same time.
If a sheet is called Sheet 3, or a field says customer when everyone says client, rename them. Renaming is safe and it is the cheapest usability improvement available.
