- Quality filter mapping
Quality Filter Mapping is part of the
Value Stream Mapping[Global Logistics and Distribution Planning: Strategies for Management By C. Donald J. Waters ISBN 0749439300] 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 [Best Practice Procurement: Public and Private Section Perspectives: Andrew Erridge, Ruth Fee, John Mcllroy ISBN 0566083663]
• Product Quality – Defected Item provided to customer
• Defect Quality – Defected item found prior to receipt by customer
• 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 post improvement plan to measure the result of improvements.
