  • sing the PDCA method, your company will discover what processes need to improve.....  from what we “think” are the problems to what we “know” are the problems.  Through use of flowcharts and root cause analysis you will determine where the waste is, implement the changes, and set up measurement systems to create greater efficiencies and reduce the areas of waste.
  • Standard defined problem solving methodology should be applied on the basis of the complexity of the task since it requires high amount of manpower and time.
  • PDCA has a laid a systematical background to the problem solving but there are many problem solving tools :8DDMAICTRIZ ( German Standard for inventive problem solving) Rapid problem resolution (IT)Grow ( Goal, reality, obstacles and way forward) Math approachKepner-TregoeDMADV- Define, measure, Analyse, Design and VerifyLean Kaizen Six sigma tool box: Kano Model-customer requirement structuring
  • The PDCA Cycle (figure 4) was originally conceived by Walter Shewhart(1930), and is often referred to as "the Shewhart Cycle". It was lateradopted and promoted for quality purposes very effectively by the famousQuality Management authority, W. Edwards Deming. The model provides aframework for the improvement of a process or system and is shaped byfours main steps: plan, do, check and act.
  • D0-Gathered very shortly after defect was found ( info lost with time) like: m/c, operator, batch details, time of failure, processing conditions and special circumstances. 8D is extensively used when there is a defect. Application: AutoManfHealth careData processingSoftware developmentFinancial Services
  • Gemba is a japanese word means the real place or job floor or production floor where the value addition activity wrt the customer takes place.
  • ( Capability index, process centricity index, histograms, pareto graphs etc )
  • e.g. specifications, training manuals, or “mistake proofing” the process
  • 8D problem solving
