5.2 Drop in Duration of Tasks
On the other hand, the duration of the
Resolution
task significantly drops in the
Im-
plementation
and
Component and Integration testing
phases, while the duration of the
Analysis
and
Evaluation
task increases. The decrease of the
Resolution
could be ex-
plained by the fact that the project had a fixed deadline. It was not possible to spend
more time on the
Resolution
activity because of the fact that more time was simply
not available. This hypothesis was also given by the organization that provided us
with information prior to our analysis. However, this hypothesis does not explain the
increase of the duration of the
Evaluation
task
5.3 Total Throughput Time
Considering the total throughput time of a case, the throughput time is the highest
during the
Specification, Design, System testing, Customer testing
and
Consumer use
