Implementing Lean in Software
Unknown to many, all supply planning applications have “Lean” controls built within them. And there are in fact some situations where a reorder points will provide a superior output. With supply planning, even within a single company, it is not one size fits all. The trick is understanding when to deploy each of the approaches available in software that companies already own.

There are simply a great number of misunderstandings regarding reorder points – misunderstandings that this book helps clear up.
Rather than “picking a side,” this book shows the advantages and disadvantages of each.
- Understand the Lean Versus the MRP debate.
- How Lean relates to reorder point.
- Understand when to use reorder point.
- When to use reorder points versus MRP.
