Table 13 Hypotheses for the maintenance study

From: Model-based reuse for crosscutting frameworks: assessing reuse and maintenance effort

H0 m There is no difference between using editing a reuse model and editing the reuse code in terms of productivity (time) when maintaining an application that reuses a CF.
Then, it is equivalent to edit any of the artifacts. Tc m - Tm m 0
Hp m There is a positive difference between using editing a reuse model and editing the reuse code in terms of productivity (time) when maintaining an application that reuses a CF.
Then, editing the reuse code takes more time than editing a reuse model during maintenance. Tc m - Tm m > 0
Hn m There is a negative difference between using editing a reuse model and editing the reuse code in terms of productivity (time) when maintaining an application that reuses a CF.
Then, editing the reuse code takes less time than editing a reuse model during maintenance. Tc m - Tm m < 0
  1. Considering the Reuse Study, there are three hypotheses for the outcome. In the first one, both are equivalent, while in two of them, a technique is faster.
