What are different characteristics of Capability Maturity Model (CMM)?

Capability maturity model or CMM as it is often abbreviated. It is a development model developed after a prolonged study of the data collected from various organizations from all over the world.

Characteristics of Capability Maturity Model
1.The development of this model was funded by the USDD (United States department of defence).

2.The capability maturity model became the foundation for the development of software engineering institute or SEI as it is popularly known as.

3.The term “maturity” emphasises process optimization and level of formality.

4.Processes are optimized from ad-hoc practices to steps that have been formally defined.

5.Nowadays this model is being used effectively for management of result metrics.

6.Capability maturity model has proved to be great help in active optimization of the processes.

7.This model allows improvement in the development processes of an organization.

8.It is an effective and good approach towards improvement of any organization’s development processes.

9.This model is securely based upon the frame work of process maturity which was developed in 1989.

10.Initially it was used for objective assessment of the processes carried out by the contractors of the government to keep a track on the project.

11.CMM is not only used in the field of software engineering but, it is also applied to organizational processes of a business.

12.It is used in other fields like:
- Software development
- System engineering
- Software maintenance
- Project management
- System acquisition
- Risk management
- Information technology
- Human capital management and
- Services

Where is Capability Maturity Model used?

Capability maturity model is being extensively used in various organizations like in commerce, government offices, software development organizations and industry.

What was the need for Capability Maturity Model?
- In the 20th century the use of computers was wide spread.

- Computerized processes were thought to be less costly, effective and flexible way to carry out tasks.

- As more and more organizations started adopting computerized processing systems, the demand for software development eventually rose.

- As a result CMM was developed, of course with lots of failures.

- The computers were a new technology at that time and so there was a lot of pressure on developers to deliver quality products within a stipulated period of time.

- The US military was in havoc that because all their projects were running out of budget and time.

- So in order to know the reason behind all this, they funded the study at SEI. Active study started at SEI.

- It was watts Humphrey who actually came up with the actual idea of CMM.

- He based his approach on the evolution of software development practices.

- He concentrated on all the processes as one instead of concentrating on just one software development process.

- Since then the CMM has become popular among various organizations and is used as a powerful tool for improving overall performance of the business.

Though CMM proved to be a very effective tool for business but many times it caused problems in software development.

- CMM didn’t allow use of multiple software development practices. It was superseded by CMMI.

- These days still the capability maturity model is being used as the model with the capability of handling general processes when it comes to public domain.

Some Important Facts About CMM
1.CMM is still maintaining its position as a model of maturity of process.

2.CMM provides a place to start the development.

3.It uses a common language and the development is based upon a shared vision.

4.It effectively develops a frame work for actions according to their priority.

5.For an organization it defines the ways for improvement.

6.It is used an aid for better and effective understanding.

CMM has 5 aspects:
- Maturity level
- Key process area
- Goal
- Features
- Practices.
