Six Sigma

Initially used in manufacturing operations as a methodology for defining and improving processes, Six Sigma's broad applicability has been acknowledged across all enterprises. Through mathematical measurement, the goal of Six Sigma qualified processes is to perform tasks better, faster and at reduced cost.

The Six Sigma approach:

• Identifies quantitative business goals - goals which provide direct value to the customer.
• Identifies specific processes with the greatest influence over business goals.
• Identifies critical inputs affecting process performance and goals are related to changes in process outputs.
• Proposes improvements which are implemented on a pilot basis and, if measurements indicate goals have been achieved, institutionalised.

Individual processes are selected based on their ability to affect business results and provide visible value to the customer. The connection between process performance measurement and business is always explicit, so it is comparatively easy to measure return on investment.

Unlike the model based approaches to process improvement such as the Capability Maturity Model Integrated (CMMI), Six Sigma is not domain specific. Six Sigma does not include any process models.

Pirean adopt Six Sigma techniques to provide a continuous improvement methodology. Following Six Sigma's DMAIC (Define, Measure, Analyze, Improve and Control) methodology for process improvement, we measure process and software development against our clients’ requirements - providing rigorous in-process metrics, cause analysis and continuous improvements throughout the development lifecycle - ensuring defect free deliveries and a lower cost of development.

Through adoption of Six Sigma quality measures Pirean ensure all projects are customer focused and all deliverables meet specified requirements. Through our process of continuous improvements the number of defects found and project development time is reduced, leading to the rapid deployment of premium quality deliverables.

Through effective knowledge management and a healthy proliferation of cross-training problem resolution and time to delivery are reduced, bringing tangible cost savings to the customer.
