If ISO 9000 defines the level of quality, then Six Sigma defines an approach for improving business processes to achieve client satisfaction, by providing the underlying quality standard for all of United Advisors’ business practices.

Six Sigma is a system of practices originally developed by Motorola to systematically improve processes by eliminating defects. Defects are defined as units that are not members of the intended population. A high sigma means few defects. Six Sigma has become an element of many Total Quality Management (TQM) Initiatives.

Six Sigma has two methodologies: one is used to improve an existing business process; the other is used to create new product designs or process designs in such a way that it results in a more predictable and reliable defect-free operation. In each case designing, measuring, analyzing, improving and controlling the business methodology or process is critical to ensuring a low level of defects.

Six Sigma is based on a few key concepts that define and describe quality in any particular business:

  • Critical to quality: attributes most important to the customer
  • Defect: failing to deliver what the customer wants
  • Process capability: what your process can deliver
  • Variation: what the customer sees and feels
  • Stable Operations: ensuring consistent, predictable processes to improve what the customer sees and feels
  • Design for Six Sigma: design to meet customer needs –both internal and external customers — and process capability


United Advisors has spent a great deal of time defining and analyzing each of our business processes in the manner described above. We have developed the documentation that employees will follow to ensure that these processes are repeatable and not subject to wide variation in outcomes. Our ultimate goal is to continuously improve our processes and capabilities in order to meet our customer needs.
