We watch the work, not just the final spreadsheet.
We want to understand every meaningful task: why it exists, what triggers it, where the data comes from, how staff complete it, what is manual, what gets handed to somebody else and what the final output is supposed to achieve.
That means a reporting problem may lead us upstream into data collection, inconsistent templates, email-driven handoffs, unclear ownership or a task that should not exist in its current form at all.
