based on BRS orgn. Quality people prepare the srs of 
project this document should be accepted by customer.

There are some criteria which a project or test manager 
signs off the project..
1. If the budget gets exceeds the proposed.
2. If the time for completion is getting increased while 
the implementation date is closer.
3. When atleast 90% of test cases are executed and no 
critical or major bugs are in open status.
4. When the application is not stable more to test!!!!

Project Sign-off means the product is deliverd to the 
client and the client has accepted the product, so that the 
Software service provider(Software development company) 
will no more be responsible for any sort of further 
development/maintainance/modification without any seperate 
OR new billing for the same.
