Quality Filter Mapping is part of the Value Stream Mapping toolkit and is used to analyse processes/functions with respect to Quality.
The results of a Quality Filter Map shows how much waste is being generated within an organisation at each stage of the process.
Three types of Quality are measured as part of the model
• Product Quality – Defective Item provided to customer<br />• Defect Quality – Defective item found prior to receipt by customer<br />• Service Quality – Defect that affects the ability of the supplier to provide the service or product to the customer
Quality failures/defects are represented as a ratio (typically parts per million).
Results of Quality Filter Mapping are commonly used to feed into continuous improvement plans. A revised map is then generated after implementation of improvement plans to measure the result of improvements.
