 # Project Analysis
 Project level analysis enables us to understand key metrics such as slot_time, bytes_scanned, bytes_shuffled  and bytes_spilled on a daily basis within a project. The metrics are examined as averages, medians and p80s. This enables us to understand at a high level what jobs within a project consume 80% of the time and 50% of the time daily.
