Quality certifications for an organization are an important yardstick to judge the maturity of an organization's systems by comparing them to the best industry practice. They instill confidence in the organization's performance, processes, and products or services. ISO which stands for International Organization for Standardization and CMMI which stands for Capability Maturity Model Integration are two such quality benchmarks established for organizations. Let us look at some of the conceptual differences between the two:  CMMIISO CMMI is a process model  ISO is an audit standard  Best practices related to product engineering and software development  Certification for businesses that meet defined quality standards  Applicable only in the software industry   Applicable to all manufacturing, IT, and Non-IT industries  Focus on engineering and project management practices  Focuses on all processes and quality standards  Compares existing processes to industry best practices  Require tuning of existing processes to confirm specific ISO requirements
