Determine evaluation criteria
Use the Service Model, Software Architecture Document, and the Component Model to identify criteria against which
the Architectural Proof of Concept is to be evaluated.
|
Decide on construction approach
Select the techniques to be used for constructing the Architectural Proof of Concept, for example:
-
Conceptual modeling
-
'Rapid' Prototyping
-
Simulation
-
Automatic translation of specifications to code
-
'Executable' specifications
-
Construction of 'spikes' as prototypes - vertical slices through layers
You need to be able to reason about these models, in the process discovering something about both problem and
solution spaces.

Select assets and technologies for proof of concept
Select the assets and technologies to be used to construct the proof of concept. In this case, prime
assets will include the components which are the current candidates for realizing the service that is being considered.
|
Construct proof of concept
Work with the developer to build the proof of concept, using the selected assets and technologies, to determine
whether the chosen realization approach will satisfy the Quality of Service requirements of the service.
|
Evaluate proof of concept
Test the proof of concept against the evaluation criteria. How this testing is performed will depend on the
form of the proof of concept. For example, in the case of an executable prototype, this might be through demonstration;
in the case of a conceptual model, through inspection and reasoning, or, for a simulation, requiring the set-up and
running of the simulation model with input data derived from the evaluation criteria, then the collection and analysis
of output data from the model.
|
Assess Results
Assess the evaluation's results to determine whether the attempted approach delivers the Qualities of
Service that are specified for the service that was being considered. If so, this can be noted in the Design
Model and in the Software Architecture Document as a "closed" issue. If not, work to identify (and then
assess) an alternative solution for realizing the service.
