The basic relationship, WIP = CT x TH known as Little’s Law has wide application in both production systems as well as projects . However, when some parts/tasks are never completed because they are either scrapped (yield loss) or have become obsolete (as in a project), the application becomes a bit more complex. This study presents an analysis of these situations and concludes with a more general set of Little’s Law equations, as referenced in Factory Physics .
