Why PI?

Never Able to Configure Power Suite to Real Plant Environment

Reports Were Not Valid and Had to Redo Manually Using Spreadsheets with Manual Input from Bailey Logs

Power Suite Only Handled Under a Hundred Data Points and Was Unable to Support Technical Monitoring

There Was a Need for Fast, User Friendly Interface to Support Operations and Business Decisions
