About Lean SchEduling International (LSI)


LSI was founded by Mike Liddell and Dan Hahn in (2001) to help manufacturers adopt and succeed in the implementation of innovative Advanced Planning & Scheduling (APS) software solutions. Combining their skills, Mike and Dan created and perfected a unique process designed to take manufacturers from a typical but flawed ERP planning and scheduling to a process that is driven by customer demand while delivering on exceptional customer service.

LSI not only helps clients select the right solution, we also help them implement technology, we also help our clients get more from their investment by implementing better business processes in ways that extract its full potential throughout the manufacturing workflow.

Commitment to the Right Solution

It can be easy to lose sight of your business objectives when you see a sexy looking APS demo and a clever sales pitch with the latest in high-tech gimmicks. The reality is that over the last 20 years, LSI has seen many systems come and go. This has left a trail of unhappy customers who invested a significant amount of time and money on something that never actually worked for them.

Our deep software and industry expertise allow us to deliver APS solutions that address your specific planning and scheduling needs. By avoiding the numerous and expensive pitfalls that typically ruin most APS implementations, LSI helps you drastically reduce the amount of time it takes to realize measurable results while putting in place a growth platform that allows you to constantly improve and innovate.

Relationships are everything

LSI has stood the test of time as a business because we develop earnest relationships with each of our clients. The hard truth is that most ERP resellers and consultants lack the in-depth knowledge and experience that can only be gained through years of working in the trenches. We take the time to put in place an LSI team that will deliver the results you expect and the skills you require. In the end, the only people who can give you the full story of what it takes to succeed are our customers.


With almost 100 years of combined experience, LSI’s team of technical and sales consultants helps customers pursue innovative concepts to effectively get the best out of APS. Whether it is a pre-sales consultation or post-sales software implementation or training, LSI’s staff is committed to the customer during the entire process and beyond. Please meet our team.

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 APS solution is to adopt a three-legged stool strategy.
Unless you take time to ensure all three legs are firmly in place, your APS solution will give you only minimal benefits.
