STEP $1$:

$1.$ What would be the best process $($or next future state$)$ for this product?

$2.$ Draw a new VSM according to the best knowledge available for target.

What would be the Future state VSM of this product?

STEP $2$:

$1.$ Calculate:

a$.$ Lead time.

b$.$ Throughput

c$.$ Inventory $($WIP $=$ Work in Process$)$

$2.$ State the Findings of the process based on calculations.

$3.$ Analyzing the reasonability of planned changes for this drawn VSM and for the future VSM$,$ what does your calculations reveal about processes?

$4.$ How do results become better in each case $($VSM$)?$

$5.$ Design some possible changes to impact source data.

$6.$ Try some other values in calculations $($simulate a bit$)$

$7.$ Are planned changes reasonable in each case $($VSM$)?$

$8.$ What does it require to implement those changes in reality?
