This document summarizes a presentation given at the Lean Healthcare Forum in 2006. The presentation discusses why lean principles are applicable to healthcare, focusing on reducing waits and improving information flow through linear processes like emergency admissions. It provides examples of applying lean to optimize hearing aid processes, initially reducing contacts from 4 to 3 and the process time from 705 days to 60 days. The presentation notes that lean efforts should start with important but limited areas, and have sufficient buy-in, while avoiding pre-set targets that could undermine the work.
