SIRF Inventory Management from a LEAN perspective - Dave Harnett from Continuous Wave

Thanks to all for attending the online SIRF OERt Masterclass | Inventory Management from a LEAN perspective on Tuesday 28th March 2023.

Our sincere thanks to Dave Harnett from Continuous Wave for sharing his experience, insights and knowledge around the practical application of LEAN principles to inventory management.  From Dave’s presentation it was clear that the same LEAN principles that were originally applied in the automotive industry, has proved to readily work across multiple other industry sectors.

Inventory Management from a Lean Perspective

Attendees expressed the following AIMS from this session:


  • Inventory management philosophy in light of supply chain challenges & cost
  • Optimization of inventory management with no interruption on finished goods
  • What to keep, when to keep, how to keep, and at what cost
  • What may be the best inventory approach/practice for my business
  • Applying which LEAN methodologies to achieve
  • How to control and optimize inventory over multiple sites and large geographic area
  • How to implement measurable improvements to support change to our business
  • How would “make to order” type orders work when short orders and variations to inventory needed.


Detailed and pointed questions raised by attendees were answered by Dave by quoting from practical solutions applied to actual industry IM situations and duly noted.  Particular interest was expressed around the application of Cyclic Supply,  Material Flow (Kanban) as well as the 80/20 rule applied to inventory storage.
