Testing and Evaluation
Having completed manufacture, assembly and wiring the next stage is to test the artefact to see how
well it performs. At this point it is necessary to revisit the requirements, as identified in the analysis,
and test the operation of the artefact under these headings.
A clear outline of the tests carried out as well as factual information resulting from the tests must be
presented. The tests must be designed such that they can identify to what extent the artefact satisfies
the design requirements. Tests may show up shortcomings in the design of the artefact and this may
require some redesigning and manufacture to overcome these problems.
Evaluation affords the opportunity to reflect on the completed project. In carrying out the evaluation
both the process of design and manufacture of the artefact, the completed artefact and the test results
must be reviewed. Critical appraisal, as well as possible changes to future design, is an essential
component of a thorough evaluation.
The following points may be used to guide a complete evaluation:
