Six Companies, Inc. was the contracting firm that was formed to build Hoover Dam and later went on to build Grand Coulee Dam and other large projects. It was a consortium formed by six smaller general contractors in order to submit a bid for the Hoover Dam contract. Because of the immense size of the dam, no single contractor had the resources to make a qualified bid alone. Six Companies was composed of:
Morrison-Knudsen Co of Boise, Idaho,
Utah Construction of Ogden, Utah,
Pacific Bridge Company of Portland, Oregon,
Bechtel of San Francisco, California,
Kaiser of Oakland, California, and
MacDonald-Kahn of Los Angeles, California
The dam was completed two years early, after a bid of $48,890,955.

Since Six Sigma works to reduce defects, data certification improvement programs are often beneficial for the application of their methodologies.
Since Six Sigma and data quality improvement share the same goal of reducing defects, data certification improvement programs are natural candidates for the application of Six Sigma methodologies.
Central to Six Sigma and data certification is the ability to measure data quality throughout the entire process and compare the actual outputs to the desired, required or expected outputs.
Six Sigma is a series of tools, techniques, and business metrics that represent the best in quality and process improvement -- the minimization of variation and defects from products, processes and services to almost zero.
Six Sigma and its frontline Black Belts can be the source of revolutionary and rapid process improvements leading to dramatic increases in both productivity and profitability, and ultimately to sustained enterprise growth.
Six two-day training modules are organized to allow structured implementation of Six Sigma projects and resulting in actual project ROI and certification of company Black Belts.
