Looking for Reality
And the other issue, regarding time, what is to be considered? Per rolls, per packages?
We don't know the ins and outs of your business, you do...what makes sense for this business?
If a case of 500 logo printed envelopes and a case of 1500 sheets of letterhead run about the same, then one case is one case.
If a case of 20 rolls of 1000 stickers each runs in time with a 500pc pack of manuals...there's your answer.
Consider still...it has to get down to "one".
One = 500pk manuals?
One = 20roll case of labels?
One = 500pc case of envelopes?
All of the above?
None of the above?
You have to decide what will work for your particular business flow that will give you value from your VSM...otherwise why bother?
