Explain why it is not necessary for a program to be completely free of defects before it is delivered to the customer. Under what circumstances would this be considered normal practice. Under what conditions should this be avoided

Testing is a procedure. which shows a program does what it is proposed to do and to find program surrenders before it is placed into utilization. It isn't essential for a program to be totally liberated from surrenders before it s conveyed to clients it is that it isn't constantly (99% of the time) conceivable to convey an imperfection free item to the client which is of 100% quality. What's more, trying can't totally approve that a framework is fit for its planned reason as this requires a nitty gritty information on what that reason will be and precisely how the framework will be utilized. As these subtleties unavoidably change between choosing to get a framework and conveying that framework, the testing will be essentially inadequate. Furthermore, it is essentially unimaginable for all with the exception of paltry framework to have a total test set that covers every potential ways that the framework is probably going to be utilized.  

A program need not be totally liberated from deserts before conveyance if:

1. Remaining deformities are minor imperfections that don't cause framework debasement and which are transient for example which can be cleared when new information is input.

2. Remaining imperfections are with the end goal that they are recoverable and a recuperation work that causes least client disturbance is accessible.

3. The advantages to the clients business from the framework surpass the issues that may be brought about by the rest of the framework abandons.
