Revenue per employee is one of the key metrics that the market looks at when evaluating the relative efficiency of software companies.
The numbers don't look too flash for SAS...
Microsoft $958k
VMWare $604k
Adobe $600k
Workday $497k
ServiceNow $483k
Salesforce $379k
Oracle $321k
SAP $322k
SAS $222k
Before any IPO, I expect SAS will want to lift this to at least the level of the laggards in the sector...other old legacy vendors like SAP and Oracle.
Assuming the following source is correct https://www.zippia.com/sas-institute-careers-37623/revenue/
SAS will need to reduce the workforce to about 9500 employees to have similar revenue per employee to SAP.
