Our team haven't completed any project in afternoon time and before deadline. inspite of our effort we have completed every project night before deadline or hours before deadline. Have you got these experience ?

Completion is a relative term in software industry. One can never say my product is 100% finished. There is always some polishing and bug fixing left out even after release. So basically when you are completing before deadline, you only get satisfied by the amount of work till you have no more time to improve it. Does that make sense?
