for workers in lean manufacturing—high motivation, teamwork and flexibility, and multiple skill sets—can be negatively influ- enced by an uptight working environment and lack of strategy in human resources.
Six sigma is the theme of several more popular papers. Another paper by S. Arunachalam, “Operational Excellence Through Six Sigma” (TP05PUB21), emphasizes how investing in quality improvement methodologies should be considered equally important to investment in equipment and machinery. “Combining Lean and Six-Sigma for Optimal Results”
(TP06PUB123) discusses these two powerful philosophies and their supporting tools for improving quality, productivity, profitability and market competitiveness in a holistic manner. Authors Elizabeth Cudney, Merwan Mehta, and Richard Monroe propose using the DMAIC process, a basic six-sigma tool, to merge the implementation of both philosophies, re- sulting in impressive results and substantially reduced waste and variation.
Maintenance can be a large overhead expense in most
lean facilities. “Six Sigma Keys to Lean Maintenance Reliability in 30–60 Days” (TP04PUB308) by Howard C. Cooper uses DMAIC to help eliminate root causes of unscheduled downtime and scrap and rework (low yield) in several plants. With proper expertise, these methods can be implemented in 30-60 days for 70–92% reduction of unscheduled downtime. “Preventive Maintenance of Dies” (TP07PUB190), as author C. Padmanab- han from India describes, involves rectifying quality issues—like scratches, burrs and breakage—as well as quantity-related issues such as ejection, handling and packaging. The cost of preventing failure is less when compared with the cost of repairing. Just as important is a tool that is properly designed so its operation can be predicted. The data from die performance and production feedback will ensure positive results of preven- tive maintenance and become predictive maintenance.
