Implementation to Customer

Implementation artifacts delivered to the customer must match the artifacts delivered to test.

It is possible for parts of the implementation to be withheld from the customer, so the released executable code is often a subset of the tested executable code.

The implementation may include internal support for test execution and performance profiling. These features may be turned off for the customer if they affect the behavior or performance of the product.

Another category of implementation artifacts that go directly to customers is screenshots included in documentation.
