Product Quantity Process Routing Matrix
PQPR matrix is a combination of the Product Quantity (PQ) analysis matrix & the Process Routing analysis (PR) matrix. It is used as a valuable tool to prioritize the focus of improvement efforts on building VSM for a range of products.
Product Quantity (PQ) analysis matrix is the tool that shows us to focus on the product family that contributes highest volume or highest revenue as compared to other product varieties in the organization and helps the lean manager to maximize the profits
Process Routing analysis (PR) matrix is the tool that helps to prioritize the product family having similar process steps and the manager’s take the decision on which product family to map first
Operations will be benefited by using PGPR matrix:
· When a manager wishes to develop a VSM to optimize its manufacturing processes for a variety of items,
· When a PGPR matrix can be prepared for the entire product range.
· When PGPR matrix aids manager in deciding which product range to prioritize for creating VSM
· When managers prioritize boosting the organization's margins
Example:
XYZ manufacturer produces only pain relief products in the form of balm, spray, liquid, gel, etc.
PQPR matrix 1 shows the list of pain relief products along with their sales volume and the processes followed in manufacturing. PQPR matrix 2 explains how products having similar processes are combined to a product family
With the help of PQPR matrix, lean manager takes the decision to focus on products of Product family no. 1 first since high sales volume % of 42% contribute’s to organization’s revenue and the manager builds VSM for Product family no. 1 first to improve the process thereby increasing the margins. Then, he gives the 2nd priority to Product family no. 2 and 3rd priority to Product family no. 3 for process improvement by building VSM
