Many people
have asked me how to depict the Inventory or the Cycle Times when those are in
parallel on the real process.
Do they
must make the sum or take the biggest?
The answer
is: for Inventory you must consider the biggest,
however for the Cycle Time you must do the Sum.
Please see
the example on the VSM Toyota 500N center cell current state second quarter
2004.
Fig.
Please note
that for the first processes of VSM the cycle time considered on Lead Time (VA)
was the sum of (30 sec + 2 sec + 62 sec = 94 Sec).
And for the
Inventory that coming from those processes was considered the biggest one of
the 4 Inventories ( 4 Days, 5 Days,
4 Days 1.5 Days) , to be represented on
Lead Time as NVA.
Same
considerations were taken for the VSM Future Toyota 500N center Cell Quarter
2004.

I really
hope this can help you on your next projects.
