What it should show at a glance
The single most useful screen in a workshop system is the day: vehicles on site, what stage each is at, and what is blocking anything that is stuck.
If that screen is accurate, the office stops walking into the workshop for updates.
What it should not do
It should not ask technicians to duplicate what they have already written, and it should not require a training course to record a completed job.
Reporting comes last
Owners buy for reporting and get value from the daily view. Reports are only as honest as the data entered during a busy week, so ease of entry decides report quality.
