Human Factors; Procedure
In cruise; Dispatch sent this message. 'Operations just called; revised Take Off Weight (TOW) 140.1. +900 LBS. Better late than never I guess.' We adjusted Zero Fuel Weight (ZFW) accordingly. Although nothing bad happened; this could create a greater problem since we took off with the wrong data. An engine failure or abort at or near V1 could be unsuccessful as a result.Preventative Measures: Some type of ground operations check and balance to verify weights.
