ISO 9000

22

BackgroundWhat is ISO?

International Organization for Standardization Formed in 1946 to promote standards that would

facilitate international communication and trade Headquartered in Geneva, Switzerland Has over 90 member countries If a country adopts a standard, they may or may not

legislate its use The United States is represented by the American

National Standards Institute

23

Background (continued)

What is ISO 9000? A series of international quality standards (not just for

software) As of 2007, over 100 countries, including the U.S. and

the European Community (EC), has adopted ISO 9000 ISO 9000 is extremely popular in the EC, so companies

wanting to do business in Europe need to strongly consider ISO 9000

24

Philosophy

ISO 9000 standards place emphasis on the customer's quality requirements andapplicable regulatory requirements

while aiming toenhance customer satisfaction and achieve continual improvement of its

performance in pursuit of these objectives.

25

Registration

ISO 9000 Registration Certificates Obtained through third-party assessment That is, ISO accredits third-parties as ISO 9000 registrars

Unlike CMMI, there are no maturity levels, only “certified” or “not certified”

Initial registration commonly takes a year to 18 months The registrar conducts an initial on-site visit, and then

(after registration) does a follow-up visit every six months
