The primary goal of our LEAN MANUFACTURING SYSTEM is the reduction and elimination of MUDA or WASTE in our production processes and support systems. Some examples of Muda are: Overproduction, Unnecessary Inventory, Inappropriate Processing, and Defects. With our ongoing commitment to continuous improvement and Kaizen, Walker Corporation has developed specific systems and methods for controlling these types of Muda.

Overproduction simply means producing more than what is actually needed by an upstream process or customer. Unnecessary Inventory is generally the result of poor information flow and batch processing. Walker Corporation has developed and implemented an inventory visual system for controlling overproduction and unnecessary inventory. By using a combination of digital photographs, part identification, part flow, required minimum-maximum stocking levels and defined locations; a very effective, standardized production and inventory control system has evolved.

Inappropriate Processing refers to the inclusion of non-value added operations into the process stream. Walker Corporation is committed to the elimination of non-value added work by systematically and consistently identifying it, determining its root cause and implementing countermeasures thorough Kaizen problem solving to ensure its removal.

Defects refer to defective product and information. Walker Corporation’s commitment to achieving Zero-Defects, utilizes standardized work, on-going training, one-piece process flow, gaging and Pokayoke (mistake-proofing devices) to ensure robust, standardized processes where abnormalities are easily detected.
