Operational Intelligence and Sustainability - A Game Changing Opportunity

Organizations across the world pride themselves on their tailor made operations and processes that form the centre of strategies and core values. It is well understood that Sustainability and Profitability to an organization is always aligned around these critical operations, processes and policies.

The Sigma Sustainability Institute (SSI) was established to address the problem of aligning sustainability and intelligent process improvement to profitability and overall organizational well-being.

The SSI Management Framework and Methodology (MFM) is a field proven approach to operation and process centred sustainability and performance management. Achievement of the required Operational Intelligence is done through comprehensive business process re-engineering and improvement through tried and tested measuring, monitoring and analysing tools.
