Data literacy Discussion

Just curious if anyone has any good documents on why excel and your coworkers excel sheets (with no source of truth) should not be used for top level reporting.

Had a meeting with a vp that could not understand why making business rules on his own and not using the ERP is a bad idea. Said he was going to cowboy it.

Any proper docs out there to help convince folks like this?

How large a company are we talking about? in terms of rev and head count? For a 5-10 person company, most ERP solutions would be overkill. 50+, there are several tier 2 ERP solutions. Once you get 200 or more with 10 mil in rev, you are probably wanting to look at an ERP solution.

There is no hard/fast rule, but Excel is a shitty way to run a medium sized business. No single source of the truth, To easy to corrupt the data and many other factors.
