type by the salient features of its most representative and discriminating members. Like
CORCAS, the CASSET report may contain any type of background variable information
describing a case that will fit in the allocated space, just as on a PRTVAR report, with “base
of assignment” and “job title” often being the most useful variables to aid analysts’
interpretations.
JOBMOD - The JOBMOD (Job Type versus Task Module mapping) program aggregates
the case- and task-level indices computed by the four advanced analysis programs and uses
these aggregate measures to relate task clusters to job types and vice versa. The description
of job types by a handful of discriminant clusters of tasks, and the association of each task
cluster with the types of jobs of which it is an important component, is a basic requirement
for defining and integrating the MPT components of an existing or potential Air’ Force
specialty or weapons system. If AFSs are to be collapsed or shredded out, or new jobs are
to be assigned to an occupational area, or old jobs are to be moved to another occupational
area, such highly summarized, yet meaningfully discriminant hard data are essential (Phalen,
Staley, & Mitchell, 1989:4-5).
Within a specialty being studied, a JOBMOD printout is generated for each job group
showing the relationships of the set of task modules to the cases representative of the job.
An example of such a printout is given below:
JOBMOD ANALYSIS OF TASK MODULES WITHIN A JOB GROUP
ST0035 Centrifuge Operators (n= 5)
01 = Number of tasks in module
02 = Average Percent Members Performing (PMP) within group performing task within the nmdute
03 = Average sum of Percent Time Spent (PTS) for group performing tasks within the module
04 = Percent of most time-consuming task s’time covered by tasks in module
OS = Percent of tasks in module which are core tasks for the group
06 = Percent of the group’s core tasks which are in the module
07 = Percent of tasks in module which are discriminating or unique for the group
08 = Percent of group’s discriminating or unique tasks which are in the module
