It is possible to meet all project specifications and not meet client expectations or fail to meet one or more specifications and still meet or exceed a client's expectation.

Meeting project specifications is important, but ultimately the goal is to satisfy the client's needs and expectations. It is possible for a project to meet all specifications and still not meet the client's expectations, perhaps because the client's needs were not fully understood or communicated. On the other hand, a project may not meet all specifications but still exceed the client's expectations by delivering key features or benefits that were not originally requested. Ultimately, client satisfaction should be the main focus of any project.
