If your ERP project is struggling, the root cause is usually 3–6 months before go-live.

Why the Evaluation Phase Is Where Damage Starts

Growing businesses often begin ERP evaluation under pressure. Current tools are causing pain. The team wants relief. Vendors are showing polished demos. In that environment, the temptation is to move fast — and that’s where projects go off course.

6 Pre-Project Mistakes That Kill ERP Success

1. Buying from the demo instead of the business case

A great demo shows potential, not operating reality. Before looking at any platform, define: What problem are we solving? What does success look like in 12 months? How will we measure ROI?

2. Starting without clear process ownership

ERP projects fail when key business decisions stay unresolved. Who owns order flow? Who resolves process conflicts between departments? Without named owners, implementation becomes endless debate.

3. Treating data cleanup as a technical task

Data migration is a business task disguised as a technical one. Customer records, inventory values, pricing logic — all of it shapes implementation quality. Deferring cleanup creates compounding problems from day one.

4. Treating every workaround as a requirement

Not every current process should be preserved. Many businesses have years of workarounds built around old tools. Translating all of them into ERP scope inflates cost, timelines, and adoption difficulty.

5. Choosing delivery based only on price

The real cost of a low-governance ERP decision doesn’t appear until Year 2. Undocumented customizations, poorly scoped implementations, and missing design accountability are expensive to fix later.

6. Starting before the business is ready

Platform signed, proposal approved — but no process ownership, no scope discipline, no change readiness. At that point, implementation becomes discovery in disguise. And mid-implementation discovery is the most expensive kind.

Signs This Is Happening in Your Evaluation

• Comparing demos and proposals without defining operational outcomes first

• No named process owner for key workflows like order flow or approval logic

• Data cleanup deferred with an assumption it can be handled during implementation

• Every existing workaround is being described as a requirement

• Delivery decision is primarily driven by implementation cost

What to Do Before You Issue an RFP

Hold an internal alignment session before requesting any proposals. Define two or three operational outcomes the project must deliver. Assign process owners to critical workflows. Map where data is incomplete and create a remediation plan. That work takes days — and shapes every subsequent decision.
