May 2000 MEDIC E Phase May 2000 MEDIC E Phase MEDIC - E The “E” Phase MEDIC - E Overview A Breakthrough Approach MEDIC E:Explore and Evaluate Phase Focus: To gain a quantitative understanding of how the process can be improved Key Deliverables: Quantified relationships of the inputs and other process variables to the outputs Root causes Key Drivers Analysis of waste (e.g. defects or non-value add activity Explore Evaluate Identify non value add activities List all potential factors which could explain why process variation occurs Experiment: Isolate and verify the root cause (or key driver) by testing each potential cause against alternative corrective actions Conclude what conditions have to be improved/redesigned to realise the breakthrough Explore Define precisely the problem (is/is not comparison) Explore possible causes - use a Fishbone diagram Find Root Cause: e.g. use “5 whys” Hypothesis generating/testing Non-Value-Added Analysis Some examples on non-value added activities Proof-reading Counting the amount of work Inspection and checking Sorting work Logging information Checking calculations Reviewing and approving Moving and set-up Monitoring work Stamping Any type of rework Use tables to analyse process map elements And Quantify where possible Evaluation and Prioritisation Use a Pareto chart - preferably covering at least 80% of the gap Prioritise based on: Cycle Time Frequency Cost impact Ease of solving Root Cause Analysis Conduct a root cause analysis for the top three to five items identified in the Pareto chart Use Cause Effect Diagram for Root Cause Analysis Root Cause Analysis: Whys Root Cause Analysis: Whys Whys: Example Root Causes: Tips Rarely is there only one root cause of a problem; avoid the single solution trap It is not uncommon to find that one countermeasure will solve (or help counter) multiple root causes A fully developed root cause analysis provides a road-map for future continuous improvement efforts Root Cause = Error Cond
