Lean Simplified - Value Stream Mapping - Patient Scheduling

well hi this is Jay Arthur and let's talk about value stream mapping for lean I call it lean simplified and let me introduce you to the power tools for this they're called post notes I use the square ones for activities and the arrows for the gaps between activities let me give you an example I worked with a group a while back and it was taken 140 days to process a transaction if you will and that's it seemed entirely too long and so what we did was we started to lay out the value stream the map of what happened and first step logged a request and then they evaluate the requests and then they'd research the request and then they decide if the request was valid or not then they'd schedule an exam diagnose the patients and treat that patient now at this time this 140 days was the fastest of anywhere in the nation now I always use these little arrows to show the time in between but here's what I've learned from working in a lien environment with many different kinds of processes you quickly discover that maybe three minutes of out of every hour or spent with people doing something or machine is doing something but the other 57 minutes are all spent the products waiting on something to happen I call this 357 roll so what happened here was I asked to miss it okay so how long does to take the log to request they said nah maybe five minutes I said okay and then how long should take to evaluate the request and they said 25 days I said really you got one guy one sheet of paper working on this for 25 days and this well no actually you know it's maybe 3040 minutes to evaluate the request I said oh so there's 25 days of delay they said yeah I said okay so what happens next well we research the request really I said how long does that take and they said 120 days I said really 120 days one guy one sheet of paper and well no that might take an hour I said so there's a hundred and twenty day delay and very quickly you discover out of this 140 day process you know a lot of it is stuck in these these two boxes right here then if it's okay they schedule the exam I said how long did that take maybe 10 minutes how long before you actually get to do the exam well as much as seven days and then it might be you know maximum one day before you get around the treatment the diagnosis maybe an hour the treatment that could be ongoing so what you discover here is in that hundred and forty plus days there was only seven hours of real work in the entire process so once you've mapped the value stream then you want to figure out well how can I redesign this to get rid of these big delays especially that one and this one on top of it I said well could you just log the request and get right into a valuating well maybe I said well can you do the research request in the background and the the doctor said well we can usually tell from looking at the patient whether what they're asking for it was really caused by what they say it was caused by and so literally we can take it and go straight to scheduled exam eval schedule and get right into diagnosis and they actually cut this process down to about the maximum of the 30 days now and that's how easy it is to redesign and reevaluate a process using value stream mapping in the background here I have a picture of a painting of Jimi Hendrix by a guy named Denny dent if you go on YouTube you can watch Denny paint this particular picture in about three-and-a-half minutes it's four feet by five feet and he gave me permission to be a little bit more loosey-goosey with the value stream mapping process you can get into all kinds of detail telling what each one of these things does but until you get rid of these giant delays all those little things irrelevant anyway that's the essence of value stream mapping and speeding up your process Thanks
