Software Process ImprovementUsingCapability Maturity Model

By

Ritesh Reddy Nagaram


Introduction
Introduction:

  • Organizations which are developing software processes are facing many problems regarding the need for change of already existing structure.

  • There are many issues that have are being raised to develop a process. To overcome the issues many models have been published.

  • One of the best and most popular model in use is Capability Maturity Model [1,2].


Software process improvement
Software Process Improvement:

  • A software process is a collection of artifacts, attributes, activities, methods and procedures.

  • We use software process to build up a new software or maintain a already existing one.

  • In the way of developing or maintaining a software, introducing new methods for further refinement of product quality is called Software Process Improvement.


Software process
Software Process:

A Process is defined in 3 steps:

1)Policy: It represents general statements or guidelines of an organization.

2)Process: It describes about “what to do” in the process. It has a overview of key areas like key activities, planning, staffing, scheduling, risk management etc.

3)Procedure: It describes about “how to do” in the process. It identifies tools, methods and techniques to be used in the process [3].


Capability maturity model cmm
Capability Maturity Model (CMM):

  • CMM is a model used to improve the software process of an organization.

  • It was first described by Watts Humphery.

  • Later it was developed by Software engineering Institute at Carneige Mellon university.

  • It is the most popular and efficient model used for software process improvement [2].


Stages of cmm 4
Stages of CMM [4]:

Fig 1 Phases of Capability Maturity Model (CMM)


Initial
Initial:

  • It is the starting phase of the process.

  • It is the stage where the process is ready to be nurtured.

  • Documentation not yet prepared.

  • Initial knowledge about requirements, cost, schedule will be discussed [4].


Repeatable
Repeatable:

  • For consistent results some of the processes in the project are repeatable.

  • Key Process Areas are

    1)Requirement Management.

    2)Software Project Planning.

    3)Software Quality Assurance.

    4)Software Configuration Management.

    5)Software Project Tracking and Oversight.

    6)Software Subcontract Management [4].


Defined
Defined:

  • Its prime focus is on tailored engineering and process management.

  • Defined processes are subject to change as the time progress.

  • Key Process areas are:

    1)Organization process Focus.

    2)Integrated Software Management.

    3)Software Product Engineering.

    4)Training program.

5)Organization Process Definition.

6)Intergroup Coordination.

7)Peer Reviews [4].


Managed
Managed:

  • The main focus of this phase is about the quality of processes and products.

  • Key Process areas are:

    1)Quantitative Process Management.

    2)Software Quality Management [4].


Optimizing
Optimizing:

  • This is the final and important phase of the process

  • The focus in this phase is to increase the process performance continuously.

  • Key Process areas are:

    1)Process Change Management.

    2)Technology Change Management.

    3)Defect Prevention [4].


Conclusion
Conclusion:

  • CMM is the best model for process improvement.

  • Step by step procedure makes it easy to implement.

  • Covers all the important areas of the process.

  • Good Documentation.


Future enhancements
Future Enhancements:

  • CMM is a very good model for big organizations, but what when coming to smaller ones.

  • Quality Assurance or Checking should be done at the end of every phase.

  • Importance to staffing should be given.

  • It cannot be assured with defined results but gives the most efficient result.
