Capability Maturity Model (CMM) is short for capability and maturity models. It is dedicated to managing software development processes and improving and evaluating engineering capabilities. Compared with ISO9000 and qualification certification, it is specialized in software product development and services and is a very professional certification project. This model has been widely used in the United States and North America and is being adopted by more and more large information technology ent
I have been working for almost four years and I am always writingProgramAnd research techniques. In the past, when I was a program and Development Manager, I did not pay much attention to Software Quality Assurance. I only care about when the program will come out. Now, as a technical manager, I must consider productivity and software quality issues, the company has been using CMMS for two years. The project management and software development process
enough to cope with changes in demand, in the above cases, the demand scope is relatively clear, the development cycle is relatively loose, although the details still need to be communicated, but the time can be used to compensate for the impact of changes.
On the other hand, Party A employs a supervisor and the supervisor will follow mature project process management methods. CMMS will be his first theoretical basis. Although programmers will think

In our demand analysis and development, there are two main points that are most easily overlooked: one is the lack of demand analysis and development processes, and the user requirements are directly taken as software requirements, there is no process for Requirement Mo
, absolutely not. It is because the project managers of these enterprises are too anxious to go straight to CMMS 3 without even knowing what is going on. They ignore the objective rules of the Development of transactions and must proceed step by step. If an enterprise passes cmsv4 within two years, I am confident that it will be a purchase expense. If it is optimistic, it will take about two years for a small and medium-sized enterprise to move from c
ReadingProgramA good article about Raf (requirements ambiguity factor, requirement ambiguity factor) in CMMS is found in the magazine.It is used in our needs review and analysis at ordinary times.
RAF = (1-rmi/RT-RCO/RT-RNC/RT) * 100%
RMI: Number of requirements for error understanding
RCo: number of conflicting requirements
RNC: number of requirements to be clarified
RT: total demand
The higher the value of Raf, the stronger the requirement acq
The company is preparing to prepare for cmmi3. In the early stage, we had some contact with the consulting company and had a rough understanding of the overall process. We will take notes first for future verification.
The 22 process domains of CMMs are skipped. The first time you hear this number is doubled.
Exercise caution in using measurements for performance management. Premature application may distort collected data.

In the last week, I discussed the non-functional requirements of a project with a project developer (we have some descriptions about non-functional requirements that are relatively high ), the purpose is to implement these things.
This form of discussion reminds me of the review process in cmme. It is very similar, but it is actually different.

The review process in CMMS is that when some artifacts of the project are generated, some senior
key quality indicators of development into the empirical data range. At the same time, further analysis and summary are carried out to revise the quality objectives to guide subsequent new projects. By gradually summarizing and correcting projects, we can finally get a set of quality objectives that suit our own needs.
The third concept of CMM is also essentially based on the traditional waterfall software development model.
Many models have emerged in CMM, covering various specialized f

One of the most interesting phenomena in China is ISO, which often leads to the ups and downs of CMMs.
Many people explain this differently, but if I want to explain it, I will explain that the pure engineering dimension is too powerful. In the interests dispute, it is not a weighty weight in the face of the world, therefore, the methodology is particularly easy to understand.
This is not necessarily true, but it
requirements of the senior leadership, and there is no way to come back. It can only be enforced. However, it is likely that this is against the facts and the wishes of everyone, which leads to a conflict.
For example, you can use CMMS to manage incoming traffic.
The middle layer cannot do things as they wish. However, they are often confused and ignored.
When the middle layer implements the requirements of the higher level, it is actually just an

XML is an international standard, the tree-like control is a common and important interface elements, both in the industry have been widely supported; and, as mentioned earlier, the XML data model itself is a tree model, this structure of intrinsic similarity, so that both have a natural good binding.
