The practice of Six Sigma® really works. It takes an organization that is willing to dedicate time and resources to the cause, a consultant with a fundamental understanding of the business challenge coupled with a comprehensive Six Sigma curriculum aimed at the right people, and a versatile statistical analysis tool that provides the methods and details to generate results.

52 Projects Result in Multimillion Dollar Savings

National Semiconductor Corporation’s (National) manufacturing arm is known as the Central Technology & Manufacturing Group (CTMG). Comprised of three wafer fabs (Texas, Maine, United Kingdom), three international assembly sites (Singapore, Malaysia, China), and the CTMG group at headquarters in Santa Clara, CA, National’s manufacturing organization reported multi-million dollar savings to the bottom line, and tens of millions in soft dollar savings (cost avoidance, incremental revenue) at the conclusion of its Six Sigma initiative. During the first wave, 52 projects were completed to achieve a 72 percent project success rate. Sixteen Black Belts and 62 Green Belts, who led and contributed to these projects, were trained and supported by Thomas A. Little Consulting (TLC).

JMP® Chosen for Superior Analytics

National’s various product offerings reflect its focus on analog chips, which transform physical information – light, sound, pressure, and radio waves – into data that electronic systems, such as cell phones, flat-panel displays and computers, can use. National’s chips include stand-alone devices and subsystems in the areas of power management, display drivers, audio, amplifiers and data conversion.

During production of each of these products, JMP® software, a statistical analysis package, helps National analyze and understand what drives performance by identifying product sensitivities and the root cause of manufacturing inefficiencies. JMP provides a unique environment that allows Six Sigma practitioners to customize the software and adapt it to meet the widely varying needs of the people working in the organization.

“JMP’s analytical component is superior to the other software packages we considered, ” said Mark Seay, Director of Quality for National. “We analyzed the same data with several statistical analysis packages and found that JMP provided a more comprehensive solution for our needs.” Seay added, “Now all of our manufacturing sites are using JMP, and we found that deployment was faster from both an ease-of-use and technical standpoint.”

“JMP software’s ease-of-use and analytical power makes it the ideal analytical engine to use for Six Sigma, ” said Tom Little, President of Thomas A. Little Consulting. “JMP speeds up the overall deployment of Six Sigma as well as simplifies and standardizes many of the steps used in Six Sigma data analysis.”

Challenges Became Opportunities for Success

National wanted quick penetration and results from its Six Sigma initiative. To achieve success, there were three challenges that required attention. First, each CTMG site had its own continuous process improvement approach, but the business processes were not tracked and measured consistently across facilities. With the help of TLC, it was determined that there was upwards of 30% - 50% waste in some of the critical CTMG processes. Second, challenges persisted to secure dedicated resources to manage the Six Sigma projects and maintain the discipline and rigor of following and reviewing new business practices. Finally, the value of Six Sigma to the organization had to be proven.

Six Sigma® Training Key to First Wave Results

Thomas A. Little Consulting worked with National to set up the infrastructure for its Six Sigma initiative in the CTMG organization. The consultants developed the roadmap for deploying Six Sigma across multiple CTMG sites, and provided the training, status updates, and management support to bring each project to completion. TLC conducted the management overviews, Champion training, DMAIC training, and provided direct Master Black Belt project support. Software training for features like JMP Design of Experiments (DOE) and JMP Scripting Language (JSL) were also part of the implementation.

Using JMP’s unique DOE capabilities, National experienced dramatic breakthroughs in performance. The results were increased throughput, speed and operating efficiency of its machines, all while maintaining equal or better quality products. DOE experiments saved the company thousands of dollars by reducing variation among processes and extending tool life.

As part of the implementation, TLC generated scripts using JSL to standardize and automate reports in the Improve and Control phases of Six Sigma. The scripts simplified tasks and helped novices perform analyses easily and consistently.

“TLC did a fantastic job deploying wave one of our Six Sigma initiative, ” said Mark Seay. “Its team was very knowledgeable and applied the software and Six Sigma methodology very quickly in the context of our own projects, which adds value for our engineers.”

The projects launched in wave one focused on ways CTMG could streamline processes, increase productivity, use equipment more efficiently, extend the life of the product, and control costs. Certain projects identified ways in which CTMG could reduce defects and increase yield. “With the help of TLC, we’re using JMP in areas we would have never thought to apply it, ” Mark Seay said. “In a data-rich environment, it is sometimes hard to make sense of all the information. This is where JMP’s depth of features is great.”

Michael Haslam, Master Black Belt, said, “JMP’s speed is spectacular. It provides instant gratification by helping us identify more yield improvement opportunities. JMP provides better exploration of data, and as a result we were able to break a barrier and improve yields by one percent in the first wave of our Six Sigma implementation.”

Collaboration Streamlines Problem Solving

Thomas A. Little Consulting and JMP software help National Semiconductor understand its manufacturing process variability and core process capabilities through Six Sigma projects. TLC is the expert at helping National define the problem and prioritize tasks to generate the most immediate return on investment. Once the areas for improvement have been isolated, JMP drives performance by providing the statistical analysis tools needed to diagnose the root cause of inefficiencies and help reduce process variability.
