CMMI3 class certification, Hangzhou CMM13 class certification assessments evaluate the preparatory work proved: Before CMMI assessment, develop a plan and assess the correct documentation, to ensure that there is an experienced, trained and appropriately qualified team can be to assess, to prepare for the implementation of the evaluation process, it is very necessary. We call documented CMMI Assessment Program results, including: requirements, agreements, valuation, risk and cut methods, and practical considerations associated with the assessment (such as: scheduling, logistics, organizational background information). In addition, it should obtain and record the originator CMMI assessment program for formal approval. Prior to the development of the assessment plan, respond CMMI assessment inputs reflected documented agreement, the agreement will contribute to a common understanding of goals and CMMI assessment of the key parameters of the assessment plan. On the basis of key parameters driving the planning process to reach a common understanding on, CMMI SCAMPI assessment of the initiator and director of the appraiser should agree on the evaluation plan; initiator and evaluation team leader should plan had been to assess the technical and non-technical details of reach unanimously. The planned execution of the planning and preparation stage other activities need to be further refined. Through preparation CMMI assessment team will produce an experienced, trained and ready to perform accurate positioning of the group CMMI assessment tasks. Members of the team should get to complete their respective tasks necessary for knowledge, or knowledge before they have been proven sufficient to complete related tasks. Assessment team leader has to provide the opportunity for everyone to complete their respective tasks required for skills practice, or confirm these skills in the past has been the demonstration. Team members know each other, and began to plan how they coordinated the work. It should also be done: the group is ready to assess objective services, members of the group have been providing training and training results are recorded, when necessary, for what they do because of insufficient knowledge or skills remedial work has been completed. We believe that no matter CMMI assessment team leader training from scratch a new assessment team, or by choosing to set up a team to ensure that they and CMMI assessment team leader can form a successful group from group members experienced in its responsibility. Furthermore, in the course of preparatory work CMMI assessment, we also should have an understanding of the principles of the model cut: 1. In some applications, plan templates and routine procedures can be adjusted according to needs assessment, which and local ownership of the same process, facilitate the exchange; 2. a structured plan in favor of the process group experienced only a limited assessment organization, such as a craft like mitigation strategies, risk is the chance to find a great value ; 3. Case study material provides a variety of options to expand the training to enhance the focus of the group who are more in need of training; 4. experienced assessment team leader in the absence of case studies, the same can be managed and simulation assess behavior; 5. In all the collections have been training members of the group, to establish a working group to be managed in order to ensure their team cohesion is very important, therefore, a lot of teams are able to take advantage of established practice, the group's size, skills composition of the crop contents are part of the process; 6. The use of assessment tools may include helping plan template, sample, and plan templates on the embedded program, in addition, in order to estimate the impact assessment constraints estimate worksheet and The method is also very useful. In short, CMMI assessment is a very complex process, but also because of its uncertainty in the assessment of the practice, there must be prepared. Truth comes from practice, we believe that as more and more organizations begin CMMI assessment software, more and more successful experience for our use and reference. SEI CMMI assessment methodology of the evaluation process will be divided into Class A, B, C are three types: Class A Class assessment: a formal standard procedure, the purpose is to obtain ratings for the evaluation process to assess the need to perform all of the steps in the CMMI standard ARC needs to meet the requirements of (Appraisal Requirement for CMMI), require the formation of a formal assessment team, and the need to SEI authorized lead appraiser to assess the evaluation team leader. Depending on the level being assessed CMMI, the number of the evaluation team is usually 4-9 people, to assess the number of days for 5-10 days, and was sent to participate in the assessment enterprise ATM. Assessment methods for document review and staff interviews to assess the output material for the final evaluation report by the Director of the appraiser registered findings to SEI. See a detailed description of the specific evaluation process SCAMPI (Standard CMMI Appraisal Method for Process Improvement) "Standard CMMI Appraisal Method." SEI CMMI assessments to do business registration, and are based on the assessment of the class. Class B Class Rating: ARC only need to meet the requirements of section, and can only collect less information, but must include information obtained from interviews with fashion, no final maturity levels of the organization to produce, the head of the evaluation team can be either SEI authorized Lead Appraiser, may be composed of experienced members within the organization to play, can be considered within the organization's evaluation process, the process can be improved in the course of the diagnostic process in use, you can also conduct periodic audits to assess the development process in the organization when used. Class Class C Assessment: an informal assessment process, to meet the requirements of less ARC organize a quick process, only a relatively small procedure to determine the domain, no SEI authorized appraiser to give organizational maturity level. Usually for a specific minority or a project, or an assessment process for the case of a minority, or a process of implementation in the organization, is usually carried out in the organizational development process. Since 1991, CMM there have been many models, covering a variety of areas of expertise. Where there is a famous model systems engineering · Software Engineering · Software Procurement · integrated product and process development. However, when companies want in the organization of different areas of expertise to improve the process, these models differ for different areas of expertise in architecture · content and methods of limiting the ability of the organization to improve the successful implementation. In addition, such a model will be integrated within the organization also increased and improved training · certification costs. A number of professional fields including model plus integrated support for training and certification will solve these problems. CMMI (Capability maturity model integration) is to merge the three models into a framework Capability Maturity Model for Software (SW-CMM) v2.0 draft C, Electronic Industries Alliance Interim Standard (EIA / IS) 731 Integrated Product Development Capability Maturity Model (IPD-CMM) v0.98 Like other models CMM, CMMI process improvement provides guidance, rather than describing the process or processes. The actual process used by the organization depends on many factors, including applications · organizational framework and scale. CMMI will join a number of proven methods architecture, to help the group evaluate the organization of a software process maturity · ability degree, and establish priorities for improvement and implement improvements. From CMMI CMMI framework can produce different models, you must first determine which model is best suited to the needs of business process improvement. Staged description or continuous description staged Description: staged representation provides a systematic and structured way, once reached a stage model-based process improvement. Reach each stage in the process to ensure that there is sufficient infrastructure, the next stage of the process can be used as a basis for improvement. Process maturity level domain based organization, and process improvement to do some guesswork. Staged representation based on the maturity level of implementation of the provisions of the order of process improvement, which defines an organization to improve the path from the initial level to the optimized level. Achieve each maturity level to ensure that there is adequate infrastructure in the process, can be used as a basis for the next maturity level, and allows continuous and gradual improvement. If you do not know which one to choose the process begins to improve, the staged representation for you is a good choice. It gives you a set of specific processes, improvements for each phase. Decided that the group process, from ten years of research and experience in process improvement. Continuous Description: When using the CMMI process improvement model, continuous representation provides maximum flexibility. An organization may choose to improve the problems related to the performance of a single process, or you can use a number of areas in order to work closely with the organization's business objectives. Continuous representation also allows an organization to different process improvement to different levels. However, there are some restrictions in the organization of choice, because there are some process areas are mutually dependent. If you know in your organization need to improve the process and understand the dependencies between the CMMI process areas. For your organization, the continuous representation is a good choice. Or both systems engineering or software engineering Jieyou description can use continuous process improvement based on business need to choose the order, reduce business risk, which made for process improvement through ISO provides a convenient comparison. The ability to use the degree (Capability) to measure. Staged description provides process improvement has been validated order to facilitate the transplant from CMM. Use Maturity (Maturity) to measure process improvement. Systems engineering including the development of the entire system, including the software may or may not be included. Software engineering for the development of software systems, mainly in the use of the system · · quantitative scientific approach to development · run · maintenance software. Project managed by the Software Engineering Institute at Carnegie Mellon University, USA (SEI) was founded in the CMM (Capability Maturity Model Software Capability Maturity Model) certification assessment, in the past ten years, the global software industry produced very far-reaching impact. CMM has five levels, respectively, marking the software companies the ability to five levels of maturity degree. From low to high, the accuracy of production planning software developed progressively increased, the unit works progressively shorten the production cycle, the unit cost of the project progressively reduced. According to SEI statistics, by evaluating the software company's estimate for the project and the ability to control increased to about 40% to 50%; productivity increased by 10% to 20%, the error rate dropped by more than a third of the software product. For a software company, it reaches into the scale CMM2 basically developed, basically have the basic framework and methodology of a modern enterprise software, with the ability to undertake outsourcing projects. CMM3 assess the need for large software integration grasp, including the integration of the overall architecture. In general, the higher the CMM certification through the level, the more likely to get their users' trust in the country, the competitiveness of the international market is also stronger. Therefore, whether through the CMM certification has become an important indicator to measure enterprise engineering software development capabilities internationally. CMM is the world recognized software products into the international market permits, it is not just the product quality certification, it is a way to software process improvement. Brocade responsible person involved in CMM assessment, said assessment by CMM certification is not a goal, it's just pushing software companies in product development, production, service and management tools continue to mature and progress, is a continuous upgrade and improve their own process capability. If a company is ultimately assessed by the CMMI certification, marking the company's quality management capacity has risen to a new level.
