VALUE STREAM MAPPING IS A LEAN-MANAGEMENT METHOD FOR
ANALYZING THE CURRENT STATE AND DESIGNING A FUTURE STATE FOR
THE SERIES OF EVENTS THAT TAKE A PRODUCT OR SERVICE FROM ITS
BEGINNING THROUGH TO THE CUSTOMER. AT TOYOTA, IT IS KNOWN AS
"MATERIAL AND INFORMATION FLOW MAPPING”. IT CAN BE APPLIED
TO NEARLY ANY VALUE CHAIN.

DEFINITION

@kmugrage
VALUE STREAM MAPPING
“EASY TO UNDERSTAND” EXAMPLES ARE EVERYWHERE

@kmugrage
VALUE OF THE CURRENT STATE MAP
GAIN A COMMON UNDERSTANDING
▸ You have to understand it to make it better
▸ Be honest, you don’t know how the software gets to prod

@kmugrage
VALUE OF THE CURRENT STATE MAP
ESTABLISH A BASELINE
▸ You need to know where you are now
▸ Helps identify waste
▸ Raise visibility

@kmugrage
CREATE A CURRENT STATE MAP
THE MEETING
▸ Everyone who does the work is involved
▸ “I know what they do” doesn’t count
▸ Don’t do this in ink, it’s going to change a lot

@kmugrage
CHOOSE A PROCESS
GET A TEENAGER TO DO HIS CHORES
▸ This has value to the whole team
▸ There is the perception of unfairness

@kmugrage
IDENTIFY THE PROCESS TO BE MAPPED
LAYOUT WHY YOU’RE DOING IT
▸ Value we expect from the process
▸ Challenges
▸ Constraints

CURRENT STATE
ACKNOWLEDGE VARIABLES IN YOUR PROCESS
▸ Lot is double sized
▸ There are two of them

@kmugrage
CURRENT STATE
PAY ATTENTION TO THE ROOM
▸ “I have a job now, I’ll pay you to do
them”
▸ Too many input sources
▸ Expensive knives should just go in
the dishwasher
Disclaimer: Not my actual house

@kmugrage
CURRENT STATE
QUALITY ISSUES WITH DOING THE DISHES PROCESS
▸ Dirty dishes sitting in the sink
▸ Dried on stuff doesn’t really wash off easily
▸ Despite best effort, dog licking dishes in sink doesn’t help

DID HE REALLY JUST DO A TALK ABOUT WASHING DISHES?
▸ You need a baseline
▸ The whole team participates
▸ Count the actual work
▸ Just stop doing the silly stuff
▸ Automate low hanging fruit ﬁrst
