Frequently Asked Questions

Why do ERP migrations fail?

According to ISG's 2026 study, nearly 60% of SAP migrations fall behind schedule and budget — primarily due to internal capacity bottlenecks and weak governance, not technical complexity.

What is capacity insolvency in IT?

Capacity insolvency occurs when an organization's planned commitments exceed its actual available throughput.

How do successful companies handle ERP migrations?

The top-performing organizations structurally bifurcate their teams — one team owns run-state operations, a separate team owns the migration build.

What is bifurcated execution in ERP?

Bifurcated execution is a deliberate architectural decision to separate the team running the current system from the team building the next one.
