Activity

(Contrast with: process, task)

If you can't describe what you are doing as a process, you don't know what you're doing.
             - Edwards Deming

An activity is a major unit of work to be completed in achieving the objectives of a process. An activity has precise starting and ending dates, incorporates a set of tasks to be completed, consumes resources, and results in work products. An activity may have a precedence relationship with other activities. For example, finish-to-start, start-to-start, finish-to-finish (refer precedence diagram).

Thanks Les, greetings from the Kingdom of Tonga

I am looking for precise definitions for a Quality Management System. The new version of ISO 9001:2015 is much less prescriptive and more flexible than previous versions. We have an external audit scheduled next month, and there are a few gaps to plug in the current QMS.

cheers
