  1. 1. Lean Construction & Continuous Improvement John Clement / Ian Widdrington 23rd June 2015
  2. 2. Golf Ball Challenge Background to Lean 5 Principles of Lean Value Adding Work & Non-value Adding Work Lean Toolbox SMED Printing Press Break 5S Numbers Continuous Improvement Tools + Cultural Barriers to Continuous Improvement Agenda
  3. 3. Golf Ball Challenge Objective: The golf ball is to touch everyones hands and end up with the person who started the sequence, in the shortest possible time. Rules: First person is the last person to touch the ball Each person to touch the ball in turn, separately 3 timed goes to see how much you can reduce the process time.
  4. 4. Definition What is Lean Construction? Maximising VALUE to you and your clients by Minimising WASTE (NON-VALUE ADDING work) Doing MORE with LESS (less time, less equipment, less effort)
  5. 5. Definition What is Continuous Improvement? Engaging with your workforce to constantly achieve incremental steps of Quality & Efficiency Improvement Some of which steps may lead to real Innovation
  6. 6. History of Lean & CI & Daniel T Jones
  7. 7. Original Gilbreth
  8. 8. 5 Key Drivers of Change Committed leadership Focus on the customer Integrated processes and teams Quality driven agenda Commitment to people. Targets 10% reduction in construction cost 10% reduction in construction time Defects in projects reduced by 20% per year Daniel T Jones contributor Sir John Egan Nov 1998
  9. 9. 1. Specify Value from the customers perspective 2. Map the Value Stream clearly distinguishing Value Adding work from Non Value Adding work 3. Flow: Uninterrupted, balanced flow between Value Creating Steps 4. Pull System dependant on Customer Demand 5. Perfection: Continuous Improvement with Site Operative InvolvementProf Daniel Jones 5 Principles of Lean

  15. 15. Transport Inventory Motion Waiting Over-production Over-process Defects 7 Wastes (Muda) 7 Wastes = Non Value Adding Work MOVE IT OVER THERE UNTIL WE NEED IT 3 Biggest Wastes
  16. 16. 8 Wastes (Lean Sigma) Under-utilised Talent Under-utilised Machinery Waste Materials Wasted Energy
  17. 17. Value Adding Work Operation that changes the product or service, moving it closer to a usable, saleable item 1. It must transform the product or service 2. The customer must be willing to pay for it 3. It must be done correctly the first time Value Adding / Non value Adding
  18. 18. 1 week cycle = 168 hours Which are the Value Adding operations? Roughly how long do they take? ~4 hours = 2.4% Value Add Value Adding Work

  22. 22. Pit Stop Single Minute Exchange of Dies SMED 7 Steps to reducing changeover time using the SMED system: 1. OBSERVE the current methodology 2. Separate the INTERNAL and EXTERNAL activities Internal activities are those that can only be performed when the process is stopped, while External activities can be done while the last batch is being produced, or once the next batch has started. 3. Convert (where possible) Internal activities into External ones. 4. Streamline the remaining Internal activities, by simplifying them - Focus on fixings Its only the last turn of a bolt that tightens it, the rest is just movement. 5. Streamline the External activities, so that they are of a similar scale to the Internal ones Practicality! 6. Document the new procedure, and actions that are yet to be completed. 7. Do it all again: For each iteration of the above process, a 45% improvement in set-up times should be expected, so it may take several iterations to cross the ten minute line.

  26. 26. Change over the press and print: or Unplug heating element Fetch tools from tool store Put on PPE Unscrew old die & remove Fetch new die from store Fit new die and secure in place Plug in heating element Adjust guides to print shape as shown Tighten guide screws Fetch printing materials from store Test print QA check using ruler Print run start How much of sequence is Value Adding? 2. INTERNAL or EXTERNAL 1. Observe Could this be improved? 3. Convert to EXTERNAL 4. Streamline INTERAL 5. Streamline EXTERNAL 6. Document 7. Repeat the process

  31. 31. Analyse the current situation, gathering data, and developing ways to make improvements Test alternative methods - establish a pilot process, or try it out with small number of customers Did it work effectively? Establish as the new norm How can we improve next time? PDCA Cycle (Deming Cycle)
