Below, we concentrate on functionality, and the attributes, measures and methods attached to that particular quality characteristic. Efficiency, maintainability and portability we find are of importance to software developers and maybe certain purchasers of systems, but not relevant to the NL focus of the present work. First, we consider the task in more detail.
