Sigma-TSI: The Open Sigma Project

Sigma is an open source multi-user relational database used to help manage engineering and construction projects. Sigma was built by project integration engineers to perfectly match the project information requirements.

Main modules include Document Control, Correspondence, Punch/Deviations, Requirements Management, Configuration/Change control, Interface management and many others.

The key to Sigma's success is the fully integrated nature of the info repositories, along the fully customizable open nature of the tool.

Sigma has evolved over many years and has many branches in use in different parts of the world. This site is home to the Sigma-TSI distribution.
