Explain the different Models in CMMIThe models in CMMI are:
1. Product and service development (CMMI for Development model)
2. Service establishment, management, and delivery (CMMI for Services model)
3. Product and service acquisition (CMMI for Acquisition model)
Development Model: It is inevitable to reach the quality product or service to customer on time. Using CMMI-DEV model, could help enterprises achieve product delivery on-time with high quality, especially the service relies heavily on software. This model is a collection of best practices which an organization follows for dramatically improvement of effectiveness, efficiency and quality of the product.
The benefits that are experienced by the organizations using CMMI-DEV are:
1. Better customer satisfaction
2. Increased quality
3. More accurate schedules
4. Lower development costs
5. Substantial return on investment
6. Improved employee morale and reduced turnover
Services Model: CMMI-SVC is a guide for helping service provider organizations to reduce costs, improve quality and improvement of predictability of schedules. The service providers deserve the development community enjoyed opportunities for years. The service providers are based on community models by practice deserves the opportunity to improve the processes.
CMMI-SVC provides best practices to
1. Decide the services providing, define services standards
2. Ensure that they obtain the elements to deliver a quality service, consumables and equipment.
3. Place the new systems in locations, change the existing systems, and retire obsolete systems.
4. Handle the elements that goes wrong for preventing from moving wrong in the first place
Acquisition Model: CMMI-ACQ is a best practice model which helps to improve relationships with the suppliers by helping improvisation of own processes. The project control can be increased, global sourcing of products could be better managed, and acquire the solutions which meet the needs of organization. This model is based on CMMI framework, and has 22 process areas, out of which six are acquisition practices specific and sixteen are shared among other CMMI models.
The six process areas that are specific to acquisition practices are
1. Acquisition Requirements Development (ARD)
2. Solicitation and Supplier Agreement Development (SSAD)
3. Agreement Management (AM)
4. Acquisition Technical Management (ATM)
5. Acquisition Verification (AVER)
6. Acquisition Validation (AVAL)Explain the different Models in CMMI.Different CMMI models are:
CMMI for Development: Describes Product and service for development processes. An organization usually does not build everything it needs for build a product. It builds some elements and acquires some to build a product. CMMI for development includes processes to manage this. It also includes best practices that address development process.
CMMI for Acquisition: Describe Product and service acquisition processes. It defines processes that provide guidance to acquisition organizations for managing acquisitions of products and services. It enlists the processes needed for acquisitions and integrates various knowledge bodies that are needed.
CMMI for Services: Describe Service establishment, management, and delivery processes. Includes guides to reduce costs, improve quality and predictability. Guides organizations to define what services they should be providing, define standards, let the world know about them.
