ERP implementation can transform a business—but when it fails, the impact is significant. Many SMEs experience delays, cost overruns, and low adoption because risks are not identified or managed early.

Failures are rarely due to technology alone. Most issues arise from poor planning, weak execution, and lack of alignment across teams.

Understanding these risks early helps businesses take proactive steps to ensure success.
