  • 25% Innovation in workbook design
  • 25% Innovation in merging of data sources
  • 25% Innovation in use of Google Cloud Platform beyond Big Query e.g. Dataflow, Google Compute Engine, DataProc, etc.

The Panel will evaluate and attribute a score between 0-100 to each Submission made up of scores between 0-25 for each of the above listed criterion. The top twenty submissions that receives the highest overall score from the Panel will be selected to continue on to Round 2.
