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

In this tutorial, we will discuss the full form and meaning of the following terms like SEI, CMM, ISO, IEEE, and ANSI with a detailed explanation. We will get to know how these certifications will be helpful in the software industry.

In this tutorial, we will explore the five different certifications along with their complete details.

Let’s move on!!


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


SEI stands for ‘Software Engineering Institute’.

SEI at Carnegie-Mellon University was started by the U.S. Defense Department to help in improving software development processes.


CMM stands for ‘Capability Maturity Model’. It was developed by the SEI. It’s a model of 5 levels of organizational ‘Maturity’ that determines the 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, they 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 complete projects successfully. If few of any processes are in place, then successes may not be repeatable.

Level 2 – Software project tracking, requirements management, realistic planning & configuration management processes are in place, and 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.


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, and not just software.

The most comprehensive is 9001, and this is the most often used one 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 show quality products necessarily, but it indicates only that documented processes are followed.


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

Among the 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.


ANSI stands for ‘American National Standards Institute’.

ANSI is the primary industrial standards body in the U.S. that publishes some software-related standards in conjunction with the IEEE and ASQ (American Society for Quality).
