Organizational Change Management Consultant Alaina Mazurkiewicz continues her thought leadership blog series.

Picture this: an ERP go-live is complete, the technical team has signed off, and leadership is breathing a sigh of relief. The system is live and functioning exactly as designed. A few weeks later, though, something is off. A floor supervisor is still tracking production outputs in a personal spreadsheet. The procurement team is manually re-entering data because the new approval workflow doesn’t feel intuitive yet. The help desk queue is longer than anyone planned for. Month-end close is running twice — once in the new SAP environment, and once in the Excel workbooks that were supposed to be retired.

This scenario is more common than most organizations expect, and the costs it generates are rarely visible on a project budget. In my experience working on ERP implementations across industries, the most persistent challenges after go-live are human, not technical.

What Is Organizational Change Management (OCM) in ERP?

Organizational Change Management (OCM) is the structured approach used to prepare employees, leaders, and business processes for the adoption of new technology or ways of working.

In an ERP implementation, OCM typically includes:

• Stakeholder engagement
• Change impact assessments
• Communication planning
• Role-based training
• User readiness programs
• Post-go-live adoption support

Without these elements, even the most technically successful ERP deployment can struggle to deliver business value.

Why OCM Gets Deprioritized

Organizational Change Management is often one of the first budget line items to be reduced when ERP project costs come under pressure. It’s harder to quantify than software licensing or infrastructure, and its value isn’t always immediately tangible. What organizations don’t always account for, is what that decision costs on the back end. The cost of a structured OCM program is something you can plan for. The cost of poor adoption, as it turns out, is something you discover after the fact.

Research from Prosci, one of the leading authorities on change management practice, consistently finds that projects with strong change management are up to seven times more likely to meet their objectives than those without it. That gap has very real financial implications.

Where the Hidden Costs of Ignoring Change Management Actually Show Up

1. Productivity loss. The post-go-live productivity dip is a well-documented reality, but organizations consistently underestimate both its depth and its duration.

Without structured OCM support:

• Productivity among affected employees can fall to 65–75% of pre-implementation levels
• Recovery can take four to six months to recover

With effective OCM in place, that recovery window shrinks significantly because employees feel prepared, supported, and confident using the new system.

2. Rework and workarounds. When users don’t feel confident in a new system, they build workarounds.

These often include:

• Parallel spreadsheets
• Manual re-entry
• Shadow processes outside of ERP

Workarounds are a signal that employees weren’t fully prepared to adopt the new system. Each workaround introduces:

• Duplicate work
• Data integrity risk
• Reporting inconsistencies
• Ongoing operational inefficiencies

Across a large organization, these small inefficiencies compound quickly.

3. Delayed ROI. ERP implementations are significant investments, and their value depends entirely on how well they’re adopted.

Panorama Consulting Group found that organizations with a structured change management approach are 33% more likely to report good or excellent outcomes from their ERP implementation. When users are working around the system rather than in it, the business outcomes that justified the investment simply don’t materialize on schedule.

4. Employee turnover. This is the cost that tends to catch organizations off guard. ERP implementations are disruptive by nature, and when that disruption isn’t managed well, disengagement follows. Research consistently links poorly managed change initiatives to higher attrition.

Replacing an experienced employee costs between 50% and 200% of their annual salary and losing several key people in the aftermath of a go-live is a cost most organizations never connect back to their change management approach.

How Much Should Organizations Invest in OCM?

Change management practitioners typically recommend allocating 10–15% of the total ERP project budget to organizational change management. For organizations incorporating OCM for the first time, that investment can seem significant. But unlike the costs of poor adoption — productivity loss, rework, delayed ROI, and turnover — OCM costs have a clear ceiling.

Organizations that invest in structured change management not only see stronger outcomes in their ERP implementation. They also build internal capability that benefits future digital transformation initiatives.

The Most Important ERP Change Management Lesson: Start Early

One of the most common mistakes organizations make is starting change management too late. Change management that begins 60 days before go-live is already behind schedule.

Effective OCM starts at the beginning of the project and includes:

• Early stakeholder alignment
• Leadership engagement
• Communication planning
• Role-based training strategies
• Continuous user readiness assessments

Preparing people for change takes time, and the earlier it begins, the stronger the adoption outcomes will be.

Technology Alone Doesn’t Deliver ERP Success

Modern ERP platforms like SAP, Oracle, and Microsoft Dynamics 365 offer powerful capabilities.

But technology alone does not drive transformation. ERP success happens when people understand the change, feel supported through it, and are confident using the new system.

That’s exactly what organizational change management is designed to enable.
