The conference

In 2020, Marris Consulting celebrates its 15th anniversary.  On the occasion of its birthday, on April 1st, (just like Apple!) Philip Marris, its founder and CEO, shared 15 client cases among the 250 cases of his 30-year career. Fifteen "war stories" of performance improvement in companies from many different industrial sectors, including: aeronautics, space, fast food, steel, automotive, MRO, pharmaceutical, rail, luxury goods, etc.

Following the success of the webinar in French that was held on the anniversary date of the 1st of April 2020 we are hosting a repeat session but this time in English on the 6th of April.

This conference was an opportunity to discover how a cocktail of Theory of Constraints, Lean, Agile, Six Sigma and common sense can achieve extraordinary improvements very quickly: 

  • Improvements in due date performance (fewer broken promises)
  • Reduction of production lead times
  • Increase in Throughput and productivity
  • Reductions in inventory
  • Improved cash flow
