About Lean Schduling International (LSI)

LSI Production Planning and Scheduling Experts for Manufacturers

Lean Scheduling International (LSI) was cofounded by Mike Liddell and Dan Hahn to help manufacturers implement smarter and more innovate APS Solutions.

Mike has 40+ years working within the manufacturing industry, initially as an ERP consultant and then after realizing their severe scheduling limitations felt that he needed to develop a workable Planning and Scheduling Solution. Mike is also the highly respected author of an international book titled “The Little Blue Book on Scheduling” and has written numerous published articles on the subject.

Dan has over 20 years experience in retail and manufacturing technologies, including system selection, project management, implementation and development. Before forming LSI with Mike, Dan had already achieved numerous accomplishments with client successes including reducing a Major Manufacturer’s inventory by $20million with a 40% reduction in clerical staff.

Combining their skills, LSI Cofounders Mike Liddell and Dan Hahn have created and perfected a unique process that is designed to take manufacturers from a typical but flawed ERP planning and scheduling process (Level 5 –see below) to one that is driven by customer demand and the need to continuously improve customer service (Level 1).

One of the things that fundamentally separate LSI from most of its competitors is that we offer as little or as much involvement from us as you desire. Some companies simply want a successful initial implementation. However, normally most clients want a long-term relationship and so we build strong long term strategic partnerships with these key clients. For the most part building and maintaining the types of innovative solutions that allow our customers to gain a competitive advantage in their industries, can only be done when there is a deep level of trust. Typically we have found that there are very few companies who can supply the level of expertise that can take a manufacturer from a Level 5 to a Level 1 or 2.

For a more detailed understanding of the different levels please see below.

APS Levels

The chart below shows the traits that we typically associate with each of the APS level. These levels tie directly to a company’s ability to compete and succeed in today’s fast paced world.

Our experience shows us that Level 4 and 5 manufacturers are not able to compete with a Level 3, 2 or 1 company and we would expect each change in Level to deliver an increase in sales volume, customer satisfaction and ultimately profitability.

Liddell notes that the APS software (Preactor) is an important part of the solution but it’s like trying to improve your golf game by buying a new set of golf clubs… it won’t work unless you have someone who can show you how to use them. Dan Hahn confirms that attempting to implement Preactor without following a proven process is likely to deliver only minimal results.

Both Liddell and Hahn point out that most companies don’t have the high levels of commitment, motivation and innovation that are required to get to Level 1 or 2.
