Why the spreadsheet always wins the first month

When the pilot started in Brno, the handover from the old system is where projects stall which is not what the brochure says. In practice, inventory planning is a people problem wearing a software costume and that is fine. In practice, the spreadsheet survives longer than anyone admits and the numbers bear it out. The honest answer is that, the biggest win is that the group chat goes quiet and that is fine. When the pilot started in Brno, the first week is about trust, not features and it shows up in the churn numbers.

What to do on Monday

On a typical site, integrations are where budgets go to die and the numbers bear it out. For food producers in particular, the handover from the old system is where projects stall and that is fine.

On the floor, nobody reads the manual, so the defaults are the product and the numbers bear it out. Once the first rollout is done, the audit trail pays for itself the first time an inspector asks and that shaped the roadmap for a year. On the floor, nobody wants another login so plan for it.
