Why LSI?

The 3-Legged Stool Strategy

The difference between implementing and building an APS solution that can give you a permanent strategic advantage is NIGHT and DAY. LSI knows with absolute certainty, the only way to achieve meaningful results implementing a successful planning & scheduling solution is to adopt a three-legged stool strategy.
