Answer:
CMM (Capability-Maturity-Model) is used to address the software QA standards. It consists of five levels as follows:
CMM's Five Maturity Levels of Software Processes
At the initial level, processes are disorganized, even chaotic. Success is likely to depend on individual efforts, and is not considered to be repeatable, because processes would not be sufficiently defined and documented to allow them to be replicated.
At the repeatable level, basic project management techniques are established, and successes could be repeated, because the requisite processes would have been made established, defined, and documented.
At the defined level, an organization has developed its own standard software process through greater attention to documentation, standardization, and integration.
At the managed level, an organization monitors and controls its own processes through data collection and analysis.
At the optimizing level, processes are constantly being improved through monitoring feedback from current processes and introducing innovative processes to better serve the organization's particular needs.
