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

· SEI = ‘Software Engineering Institute’ at Carnegie-Mellon University; initiated by the U.S. Defense Department to help improve software development processes.

· CMM = ‘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.

· ISO = ‘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.

------------

· IEEE = ‘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.

· ANSI = ‘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).

what is difference between QA and QC?and role of QA and AC?

#11 zakir on 11.26.07 at 10:21 am

@ vamsi

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.

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

#21 Ramakrishnan N on 03.05.08 at 5:43 am

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

wat is six sigma

#25 Deepak on 03.12.08 at 4:35 am

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.

#33 Joe on 05.21.08 at 10:21 am

give more explaination on CMM levels

#34 Tiger2K on 05.21.08 at 12:46 pm

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.

Tiger2K

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

#36 Suresh Balakrishnan on 06.05.08 at 10:30 am

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.

Metrics:

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:

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

Thanks,
Suresh

#44 HariPrasad on 10.15.08 at 7:42 am

Give me details of matrics

#45 SUresh Babu on 12.31.08 at 8:40 am

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.

Thanks!!

I want to have the standard for SEI CMM Level 3 certification. Which are the Certifying Bodies doing this certification. Pl. let me know.What is the preparation required , if a organization wishes to be certified to this standard?
Thanks & Regards
Priya Ahire

#53 Suresh on 12.31.09 at 4:51 am

Hi
There are plenty of certifying agencies and freelancers as well for CMMI L3 certification. The agencies are like KPMG, TUV, and DNV etc…You can search for SEI registered freelancers as well.

The approximate process for CMMI is like this,

1. Find the consultation agency,
2. Find the certification body,
3. Perform Gap analysis,
4. Perform Process definition,
5. Implementation,
6. Assessment [Stage 1, 2…],
7. Final assessment.

Thanks!!

differents b/t sei-cmm and iso9000

#56 San on 04.27.10 at 7:29 am

Hi Mani,

CMMi and ISO both are the basically quality certifications for organizations. ISO standards are generic, any of the company can implement the QMS i.e. ISO 9001:2008. There are only 8 standards in ISO9001:2008. ISO conduct surveillance audit every year and recertification audit after 3 years to ensure whether the organization is working as per the standards defined in organization’s Quality Management System.

Similarly in CMMi Level 5, there are 22 process areas and organization has to follow the same. There are accessors, who access the the organization’s processes. CMMi framework is very wise, you will have to go through with the process areas to understand in detail.

Basically these standards or process areas are just the guidelines for the organization to work.

#66 vamsi on 04.10.13 at 5:14 am

@Teja

there is no difference between CMM and SEI CMMI , SEI is a certification body where it will give the certification from Carnegie Mellon University U.S.A. CMM is now changed into CMMI where it was updated.
