I just saw an updated post from my previous colleague – a system architect in a software company. In the post he shared with me some blog pages on the topic of project management and planning. Even it is widely used or considered in software industry, but the issues and challenges they met there are more or less the same with our issues and challenges seen in project management, in the industry as an automobile sub-suppler.
Here are some of the blog pages (also some of the “laws” that linked in the page are very enlightening.)

Note: “work-in-progress” means the number of requests (work units) that are being processed, i.e. they have entered the system, but have not got out yet.
