A Overview of the Six Sigma Process

Six Sigma is a business management strategy that seeks to identify and remove the causes of defects and errors in manufacturing and business processes.

It uses a set of quality management methods, including statistical methods and creates a special infrastructure of people within the organization ('Black Belts' etc.) who are experts in these methods.

The Six Sigma DMAIC Process

Each Six Sigma project carried out within an organisation follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase).

Our Ability To Train Your People

We at Fitco can train key people in your organisation to become Six Sigma experts, namely ‘Green’ and ‘Black’ Belts. We will also train them with the TOC methodology and Lean culture.

Having such people in your company will enable you to instill a permanent continuous improvement culture in your organisation that will ensure long term profitability long after we have finished our initial project.

The Kaizen Process

A highly effective process of achieving rapid improvements is to hold a Kaizen event. This compresses a whole Six Sigma project into a week long intensive process designed to complete the project very quickly and is a proven methodology we can administer for you.
