ISO 9001 is known throughout the world as the gold standard for quality process improvement, but quality assurances experts are also discovering the power of CMMI (Capability Maturity Model Integration). This text explores how these two models can be used together to improve process quality by quantum leaps. It shows how organizations can streamline their quality process improvement programmes by capitalizing on the similarities both models share while minimizing their differences. The authors demonstrate that organizations can save valuable resources and money as they improve quality by moving towards both ISO 9001:2000 and CMMI compliance certification.
