How do we ensure completeness of the solution once designed?

In my earlier post I had explained in four lines how system can be decomposed into components, but then how exactly can we ensure our designed system matches the requirements of the client. Well for this we need to track it (requirements).

While decomposing solution into logical components we arrive at logical components by divided requirements (functional and non-functional) into logical group and further dividing them into groups. For ensuring completeness of the solution, we need a process to track down which requirement are going to be satisfied by which component.

Once we have mapping of requirements to components all we need is to check if all requirements are taken care of. If not then we need to check feasibility of adjusting missed requirements into any of the identified components or identify new component to meet the missed requirements.
