This is the second part of a two-part post. Part 1 was posted last week. 6. Optimise stock over the range The same investment in stock can produce better or worse levels of availability. This is intuitively obvious if we think of some reductio ad absurdum examples: all of our stock invested in a single […]

The author, Steve Sordy, has chosen a title that is a kind of teasing of the more dogmatic of lean devotees – British culture has little patience […]

I lent a hand yesterday at a workshop run with a client to aid configuration of an upgrade to their ERP system. The workshop, which focussed on DRP (Distribution Resource Planning) and Deployment (how we turn DRP plans into purchase orders and stock transfers), threw up the following problem.
