Examples
• Motorola: As one of the first large companies to use Six Sigma, it implemented it on
a trial basis to streamline product quality and services to increase revenues. The
results were very encouraging, and improved the overall performance of the
company.
• General Electric: GE has had issues with product quality and overall service. It
employed Six Sigma on a trial basis, and streamlined its product assurance process,
resulting in increased revenue.
• Microsoft: The secret behind their stellar service record and product line is Six
Sigma. The software and products leader is now considered a poster child for Six
Sigma implementation.
