Set of attributes

The central aim of the preparation stage of the evaluation is arriving at a set of attributes which satisfy the following conditions:

The framework as such does not offer an explicit methodology for the creation of such sets of attributes other than that it commits itself to taking ISO 9126 as a starting point. However, the PTB provides us with an increasingly powerful instrument for this process, in that it contains growing libraries of attributes and their definitions, linked to validated measures and methods.

The criteria listed above will ensure a considerable amount of reusability of the various elements of the PTB and, even where those elements may not be directly reusable, the PTB will still provide us with a repertoire of options and information to guide decisions about those options.

Section Measures will present guidelines and exemplification on the basis of work done in the TEMAA project.
