SAP Project Warning Signs: How to Know When Your Project Is Drifting Off Track

  • September 10, 2026

SAP transformations rarely go off track because of one dramatic event. More often, trouble develops gradually. A milestone slips by two weeks. A design decision remains unresolved. Data cleansing takes longer than expected. The project adds another customization. Business users miss testing sessions because operational priorities take precedence. Individually, these issues may seem manageable. Collectively, they can signal that a transformation is moving away from its original objectives. 

Recent research suggests these challenges are far from unusual. In a 2025 study from SAP and Oxford Economics, based on 800 executives and professionals at large organizations, only 51% of business transformations went according to plan, while 58% went over budget. Even more telling, only 57% were ultimately considered worth the time, money, and effort invested. 

 

KEY TAKEAWAYS 

  • Repeated schedule changes are a symptom, not the root problem. Leaders should investigate why milestones keep moving rather than continually adjusting the project plan.  
  • Uncontrolled scope and customization can quietly derail a transformation. New requirements should trigger explicit conversations about their impact on cost, resources, complexity, and timeline.  
  • Watch the decision backlog, data readiness, and testing closely. Unresolved decisions, delayed data work, and compressed testing can be leading indicators of much larger downstream problems.  
  • Business disengagement is a major warning sign. SAP transformation requires active process-owner and SME participation throughout design, data preparation, testing, change, and readiness, not just at go-live.  
  • A green status report doesn’t necessarily mean a healthy project. Leaders need objective readiness criteria and a culture where teams can surface risks early. 

 

Complex transformations will encounter obstacles. The goal for leaders is to recognize SAP project warning signs early enough to correct course. 

 

WHY SAP PROJECTS CAN DRIFT OFF TRACK 

SAP projects combine technology, data, processes, people, integrations, controls, and organizational change. Decisions in one area frequently affect several others.  

That complexity is particularly visible in SAP S/4HANA programs. SAPinsider’s SAP S/4HANA Migration 2025 benchmark found that 62% of organizations identified high project costs as a barrier to their transition, while 55% cited project length, up substantially from 37% the previous year. Research also identified adapting custom code, third-party integrations, and data cleansing and quality among the most difficult aspects of moving to SAP S/4HANA. These challenges don’t necessarily mean a project is failing, but they create conditions where small problems can compound quickly. 

The following SAP project warning signs can help leaders distinguish ordinary project friction from issues requiring intervention:

Milestones Keep Moving 

A missed milestone isn’t automatically cause for alarm, but multiple milestones moving for the same underlying reasons should get leadership’s attention. Watch for explanations such as: “We just need another couple of weeks.” “That dependency wasn’t included in the original plan.” “We’ll make the time back during testing.” Repeated schedule changes can indicate that the project’s original assumptions no longer reflect reality. 

This is especially important as organizations face increasing timeline pressure. Research on SAP S/4HANA deployment approaches found that nearly one-quarter of respondents expected their S/4HANA transition to extend beyond 2027, even as many organizations prioritize completing their deployments as quickly as possible. 

When milestones slip, leaders should investigate the root cause rather than simply update the project plan. Is scope larger than expected? Are resources unavailable? Are decisions taking too long? Was the original estimate unrealistic? Moving a date treats the symptom but understanding why the date moved addresses the problem.
