Misunderstanding: 1: CMM is better than ISO9000: CMM and ISO9000 are just a standard. The former is only a set of standards developed according to a research report, there must be a lot of imperfect places. Al9000 is an international standard, strong versatility As far as software companies, the demands in the guidelines for the quality management of the enterprise are similar. And the implementation and expression are different, and no one is better than anyone.
CMM pays attention to the process requirements, and each level has detailed requirements for the critical process to achieve, and forced companies to be self-renewed and continuous improvement to achieve defect prevention. This is very advantageous for driving software enterprises The .iso9000 94 version is focused on the elements, it is required to do, ISO9000 thinks your production process can protect your product quality. This is a very low standard .iso9000 The 2000 version has improved some content, and more mandatory things have been added to a greater extent, which requires companies to continue to improve and quantify management.
However, ISO9000 is very versatile. It is too weak. ISO9000 applicable range is the industry of all design / manufacturing / development and services, which is very low on software quality management system. The company passed ISO9000 certified enterprises equivalent to cmm. Level 2 or 3, and requires not very specific, CMM has a very detailed description of the key process domain of each level, with a 500-page description of the key implementation of CMM.
After all, CMM is only an assessment system established on the basis of an academic report. It is only applicable to the United States, and its certification results are only sent to you by SEI authorized chief assessors, and filings at SEI There is no certificate, life is used, and the middle is not reviewed. Since SEI is not a government department, this is an unimaginable for Chinese companies. Through ISO9000 certified enterprises, it is necessary to file in China Technical Supervision, and to enterprises, and require annual review, all countries participating in the multilateral recognition agreement must recognize the applicability.
ISO9000 certification cost is 2-4 million yuan, time 4-6 months, while CMM takes $ 7-10 million, every level is certified to first level, it takes 18-30 months, 2003 this standard is invalid, Instead, CMMI is
Summary: CMM is good for driving enterprise's own quality management. Its assessment standard is also very suitable for software companies, and does not need to participate in this certification for companies that do not export to the United States for software products. ISO9000's 2000 version is only able to prove that software companies can guarantee product quality. It is a minimum quality assurance requirement. It is not strong to software companies. ISO is also preparing to publish software quality system standards for the focus. ISO15504, also called SPICE. It is very similar to CMMI, but Spice is an international general standard. It is more convincing than CMMI. CMMI also recognizes this, and the expression form has a single phased expression in the form of continuity and stage, which is easy to Spice goes to CMMI.
2: Enterprise quality management is leadership, what is the relationship with us. The eight major principles of quality management requires all corporate employees to participate in quality management, quality management is the management of human management, the role of leadership accounts for the primary role in human management, but not to say that employees do not need to participate, because of specific participation design People with writing programs are employees of business. CMM, ISO9000 emphasizes the training of personnel, especially in operating the first line, the quality of the quality of the product is closely related to the operation of the first line employee. The role of leaders is to let employees consciously implement quality policy and policies, and actively participate in the quality management of enterprises. At the same time, we must fully authorize it to the next level and encourage them to complete the established goals.
3: I consciously perform the superior commands, there is no need to write a document. Whether it is CMM or ISO9000, it is required to write documentation. This is the first step in quality management, and it is also an important part of consciousness. The primary priority of quality management is to repeat. There is no document that caused the goal of non-repetition. It also causes great harm to the stability of production. Imagine that if your company's core technicians have left because they can't afford a high salary temptation. Leave a document, the people behind will follow up. If you overthrow the previous results, waste is not only money, but more important is to waste time and a chain reaction caused by delay. In this way, the development of the product enters the inward of the two difficulties. Four: Contracted the status quo of the company's quality management, there are many places that are eager to improve. 1: Strengthen leadership attention. 2: Develop a unified document format, forced write documents, and strengthen development stability. 3: Strengthen the "legal system" behavior, weaken the "human system" behavior, the company should be more institutionalized.
