EngineeringWhat is a DSS?
Turns Data into Information
Allows data driven decisions – Analysis functions (cost vs service)– Data display– Manipulated reporting
Built around business process
Securely stores data

EngineeringClosing Thoughts
Turns Data into Information
Significant value can be unlocked through DSS use– Better, consistent decisions– Data preservation– Precursor to asset management implementation
Tools built around a business process, not process built around software.
