HFMEA HFMEA stand for Healthcare Failure Mode and Effects Analysis. It is an analysis of potential failure modes within a system for classification by severity or determination of the effect of failures on the system. It is widely used in manufacturing industries in various phases of the product life cycle and is now increasingly finding use in the service industry. Failure causes are any errors or defects in process, design, or item, especially those that affect the customer, and can be potential or actual
Implementation of HFMEA Step 1- Select a Process – Select the process you want to examine. Define the scope (Be specific and include a clear definition of the process or product to be studied). Step 2 - Assemble the Team - Assemble the Team – Multidisciplinary team with Subject Matter Expert(s) plus advisor Step 3 - Graphically Describe the Process Step 4 - Conduct the Analysis Step 5 - Identify Actions and Outcome Measures

The Risk priority Number (RPN) is calculated for each of the causes. RPN is calculated by (Severity) X (Occurrence) X (Detection) Highest RPN 1000 lowest 1 RPN
5 Whys Analysis The 5 Whys is a technique used in the Analyze phase of the Six Sigma DMAIC methodology. It's a great Six Sigma tool that doesn't involve data segmentation, hypothesis testing, regression or other advanced statistical tools, and in many cases can be completed without a data collection plan.Analyze phaseDMAICdata segmentationhypothesis testing regressionother advanced statistical toolsdata collection plan
