What is SEI? CMM? ISO? IEEE? ANSI? Will it Help?

In this tutorial, we are going to discuss what is full form and meaning of the following terms like SEI, CMM, ISO, IEEE, and ANSI with a complete explanation and also we will see how these certifications will be helpful for the software industry.

In this article we providing the five different types of certifications with complete details.


#1) SEI

SEI stands for ‘Software Engineering Institute' at Carnegie-Mellon University, initiated by the U.S. Defense Department to help improve software development processes.

#2) CMM

CMM stands for ‘Capability Maturity Model', developed by the SEI. It's a model of 5 levels of organizational ‘Maturity' that determine effectiveness in delivering quality software.

It is geared to large organizations such as large U.S. Defense Department contractors. However, many of the QA processes involved are appropriate to any organization, and if reasonably applied can be helpful.

Organizations can receive CMM ratings by undergoing assessments by qualified auditors.

Level 1 – Characterized by chaos, periodic panics, and heroic efforts required by individuals to successfully complete projects. Few if any processes in place; successes may not be repeatable.

Level 2 – Software project tracking, requirements management, realistic planning, and configuration management processes are in place, successful practices can be repeated.

Level 3 – Standard software development and maintenance processes are integrated throughout an organization, a Software Engineering Process Group is in place to oversee software processes, and training programs are used to ensure understanding and compliance.

Level 4 – Metrics are used to track productivity, processes, and products. Project performance is predictable, and quality is consistently high.

Level 5 – The focus is on continuous process improvement. The impact of new processes and technologies can be predicted and effectively implemented when required.

#3) ISO

ISO stands for ‘International Organization for Standards' – The ISO 9001, 9002, and 9003 standards concern quality systems that are assessed by outside auditors, and they apply to many kinds of production and manufacturing organizations, not just software.

The most comprehensive is 9001, and this is the one most often used by software development organizations. It covers documentation, design, development, production, testing, installation, servicing, and other processes.

ISO 9000-3 (not the same as 9003) is a guideline for applying ISO 9001 to software development organizations. The U.S. version of the ISO 9000 series standards is exactly the same as the international version and is called the ANSI/ASQ Q9000 series.

The U.S. version can be purchased directly from the ASQ (American Society for Quality) or the ANSI organizations.

To be ISO 9001 certified, a third-party auditor assesses an organization, and certification is typically good for about 3 years, after which a complete reassessment is required.

Note that ISO 9000 certification does not necessarily indicate quality products, it indicates only that documented processes are followed.

#4) IEEE

IEEE stands for ‘Institute of Electrical and Electronics Engineers'.

Among other things, creates standards such as ‘IEEE Standard for Software Test Documentation' (IEEE/ANSI Standard 829), ‘IEEE Standard of Software Unit Testing (IEEE/ANSI Standard 1008), ‘IEEE Standard for Software Quality Assurance Plans' (IEEE/ANSI Standard 730), and others.

#5) ANSI

ANSI stands for ‘American National Standards Institute', the primary industrial standards body in the U.S. publishes some software-related standards in conjunction with the IEEE and ASQ (American Society for Quality).

  1. as for as my knowledge the matrices related a s/w project is tracablity matricec this document specifies the mappig the testcases to actual requirments i.e. the test cases are exaclty matching to the actual requirment or not

  2. Hi,

    Can someone please help me in preparing ISTQB exam?

    If anyone else has appeared can you please post how the topics will be and how far it is easy to prepare?

    Many people are confused about the difference between quality assurance (QA), quality control (QC), and testing. They are closely related, but they are different concepts.

    * Quality Assurance: A set of activities designed to ensure that the development and/or maintenance process is adequate to ensure a system will meet its objectives.
    * Quality Control: A set of activities designed to evaluate a developed work product.
    * Testing: The process of executing a system with the intent of finding defects. (Note that the “process of executing a system” includes test planning prior to the execution of the test cases.)

    QA activities ensure that the process is defined and appropriate. Methodology and standards development are examples of QA activities. A QA review would focus on the process elements of a project – e.g., are requirements being defined at the proper level of detail.

    QC activities focus on finding defects in specific deliverables – e.g., are the defined requirements the right requirements

    Testing is one example of a QC activity, but there are others such as inspections

    The difference is that QA is process oriented and QC is product oriented.

    Testing therefore is product oriented and thus is in the QC domain. Testing for quality isn’t assuring quality, it’s controlling it.

    Quality Assurance makes sure you are doing the right things, the right way.
    Quality Control makes sure the results of what you’ve done are what you expected.

  4. Capability Maturity Model® Integration (CMMI) is a process improvement approach that provides organizations with the essential elements of effective processes. It can be used to guide process improvement across a project, a division, or an entire organization. CMMI helps integrate traditionally separate organizational functions, set process improvement goals and priorities, provide guidance for quality processes, and provide a point of reference for appraising current processes

  5. I got more info, But till i am searching for regular expression concept in any automation tool, To resolve the related issues in the same, So please let me know,


  6. got more info, But till i am searching for regular expression concept by using automation tool, To resolve the related issues by using the same, So please let me know,


  7. the CMM topic was not clear,i need more and real time exmple for that topic,and how a company of cmm level 2 can change to cmm leve 3?

  8. Hi Friends,

    I am doing the testing for websites (manually)

    –Is there any automation tool to test the websites,

    –I have been working as a manual tester for past one year, i want to switch to other company.

    Can anyone tell me, what do i need to prepare to get the job in other companies.

    Do i need to do any course or certification for better future

    Please write me back….

  9. Testing is an art . The skill develops with more test assignments. Explore more with all banking sites and other public sites. you can find so many bugs

    Allways put yourself as an end user and test and assume different roles

  10. The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement. The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels. It can also be employed if a current process requires more than just incremental improvement. Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts, and are overseen by Six Sigma Master Black Belts.

  11. hi, i would like to learn software testing course

    My qualification is diploma in mechanical engineering & 5 yrs exp in Quality

  12. Clear information is not given on CMM & ISO as it is viewing by number of people please give required information on it. Every knows a little bit of information on it but requires understandable information

  13. @ Vijay
    One more ISO standard, ISO 27001 which is implemented in software companies for the information security.


  14. I suppose there is a mistake in full form of ISO in the article above ISO stands for ‘International Organization for Standardization’ and not ‘International Organization for Standards’

  15. Hi Joe,

    CMM means Capability Maturity model,Its a methodology used to refine and improve software developement process in a software company.
    Their are 5 levels of CMM. Any companies which practices the rules will be called as a CMM level company. Once again depending on the level which the follow. They will be certified.
    CMM is a thing of past it has been successfuly replaced by CMMI ( Capability Maturity model integration).

    The CMM defines five levels of software process maturity, based on an
    organization’s support for certain key process areas (KPAs).
    Level 1 (initial) describes an organization with an immature or undefined process.
    Level 2 (repeatable),
    Level 3 (defined),
    Level 4 (managed),
    and Level 5(optimizing), respectively, describe organizations with successively higher levels of software process maturity.


  16. What is Test Metrics & Tracibility Metrics in the Software Testing. And What is the defference between them

  17. Hi Abhishek,

    I have mentioned What is Test Metrics & Tracibility Metrics as given below:

    I think, due to similarity in phonetics the words Metrics and Matrix cause confusion. Due to confusion, few of us use these words interchangeably. So to avoid confusion and to have clarity, I would like to explain the difference between them and provide few examples.


    Metric is a measurement. We can classify Software Quality metrics as Product Quality metrics and Process Quality metrics.

    Product Quality Metrics describe the characteristics (i.e. Size, complexity, performance Quality level of the product). For your reference, I mentioned a list of product quality metrics here (not an exhaustive list):

    Mean time to failure

    Defect density

    Customer Problems

    Customer Satisfaction

    Fix backlog

    Fix response time

    Defective fixes

    Process Quality Metrics Used for improving the software development and maintenance process. For your reference, I mentioned a list of process quality metrics here (not an exhaustive list):

    Phase-based defect removal pattern

    Defect removal efficiency

    Defect arrival pattern

    Above given metrics are just a few from a huge list. We will discuss basic metrics in future blog entries. Where as in next blog entry we will discuss about test matrix and metrics can be measured using the same.


    Matrix is a data representation and data collection mechanism. Then we use collected data to derive metrics. For your reference, I mentioned a list of Matrix here (not an exhaustive list):

    Requirements Traceability Matrix

    Functional Traceability Matrix

    Test Matrix


  18. Software s also having standards…!!
    While measuring it wht wil they consider, like the application’s compatabiity r the application’s performance r somthing else. Pls tel me wht all they will consider?

  19. There is no technical term called “matrics” in software industry. It is Metrics or matrix only. I think Suresh Balakrishnan [Note no 36] has given some good comment over for metrics. In addition to that in the management level they will include schedule variance, effort variance, productivity etc…

    For Sridhar [note no 39] if you are going to start your groundwork for CMMi it would be better to get some consultation from the certifying body/agencies like KPMG,DNV, BVQi ,intertex etc..They will guide you with the quality manuals and standards.

    My personal opinion is, if you are not having any other certification like ISO 9000:2000 first get those basic certifications and then proceed .So that you can easily achieve your goals.

  20. hello everybody,
    here everybody is asking the questions but only a few answers, seems like everybody visits this site to put questions only.

  21. The deference between ISO & CMMI
    ISO : What you have documented you should follow that
    CMMI: SEI(Software Engineering Institiute) has given Generic gols,Specific gols and Specific practices based on that you should imlement.
