Twelve months after go-live, a general manager asked me a simple question: “Is this thing done?” Nobody on the team could answer. They’d been so focused on getting live that nobody had defined what “working” meant.
If you can’t measure it, you can’t claim it. Here’s how to run that check honestly.
Four numbers to pull before anyone declares victory
Don’t start with a satisfaction survey. Start with these, and compare them to the numbers you recorded before the project began. If you never recorded a baseline, use your best estimate and label it as one.
- Order-to-invoice cycle time: how many hours from customer order to an invoice that’s actually correct.
- Month-end close days: the count, not the feeling.
- Inventory record accuracy: sample 50 SKUs and count them.
- Manual workarounds: how many offline spreadsheets are still supporting core processes. This one is the honest one.
If those four aren’t better than when you started, you have a project, not an improvement.
The 90-day value review, run properly
Most companies do a go-live celebration and never schedule a follow-up. That’s why so much of the promised value never shows up.
- At day 30, list every workaround that’s been created since go-live. No judgment, just inventory.
- At day 60, pick the three workarounds that cost the most time and assign an owner to each.
- At day 90, re-measure the four numbers above and present them to the leadership team, good or bad.
- At day 180, decide what to retire: which legacy reports, spreadsheets or approval steps can be switched off entirely.
Go-live is roughly the halfway point
In most implementations I’ve seen, about 60% of the real benefit arrives between month three and month twelve. Early on, everyone’s just trying not to break anything. The gains come later, when people start simplifying instead of just coping.
A retail business we worked with cut 40 days of annual effort out of its reorder process — not at go-live, but in month seven, when a store manager pointed out that three approval steps existed to catch a problem that had never once occurred.
That’s the work of ERP Consulting after the consultants have mostly gone home: finding the rules nobody remembers choosing and asking whether they still earn their keep. Book your 90-day review on the calendar today. If it isn’t scheduled, it won’t happen.
