7.3.3 Computing a Task Set Selector Value
To select the appropriate task set for a project, the following steps should be con-
ducted:
? How do we 1. Review each of the adaptation criteria in Section 7.3.2 and assign the appro-
choose the
appropriate task priate grades (1 to 5) based on the characteristics of the project. These grades
set for our should be entered into Table 7.1.
project?
2. Review the weighting factors assigned to each of the criteria. The value of a
weighting factor ranges from 0.8 to 1.2 and provides an indication of the rel-
ative importance of a particular adaptation criterion to the types of software
developed within the local environment. If modifications are required to bet-
ter reflect local circumstances, they should be made.
3. Multiply the grade entered in Table 7.1 by the weighting factor and by the
entry point multiplier for the type of project to be undertaken. The entry point
multiplier takes on a value of 0 or 1 and indicates the relevance of the adap-
tation criterion to the project type. The result of the product
grade x weighting factor x entry point multiplier
is placed in the Product column of Table 7.1 for each adaptation criteria indi-
vidually.
4. Compute the average of all entries in the Product column and place the result
in the space marked task set selector (TSS). This value will be used to help
select the task set that is most appropriate for the project.
