around the Test Designer and Tester roles. The most important skills required for this work
include focus on test asset coverage, an eye for potential reuse, consistency of test assets and an appreciation of
As a heuristic for relative resource allocation by phase, typical percentages of test resource use for this workflow
detail are: Inception - 05%, Elaboration - 20%, Construction - 10% and Transition - 10%.
Where the requirement for test automation is particularly important, this work may take more effort and, therefore,
more time or more resource. In some cases it may be useful to assign the creation and maintenance of automation assets
to a separate sub-team, allowing them to specialize on automation concerns. This allows the other team members to focus
on the improvement of non-automation test assets.
