Factor 1: Collection Time
.
The collection time for a measure is composed of two
sub-factors which are Duration and Frequency.
Duration describes the time required to collect a measure 'A'. Frequency describes
how many times that specific measure 'A' is needed to be collected. Based on these
data, the cumulative collection time weight (CCTW) is calculated by the following
formula;

Factor 2: Cost
.
The cost of a measure is determined based on the resources required
(both human and non-human). It is comprised of one sub-factor: Utilization. Utiliza-
tion factor is related to two sub-factors which are 'Resources' and 'Expense'. Re-
sources contain the details regarding the number of resources required as well as their
cost as; No of Resources and Resource Cost. Expense involves any other additional
expenses such as the requirements for training, tools, hardware, etc.

Significant Factors for Measures Selection
We defined three classes of resources with respect to their roles in an organization
as Upper Management Resource (UMR), Middle Management Resource (MMR) and
Resource [Developer, Tester, Analyst] (R). Individual resource cost (IRC) is calcu-
lated by the following formula;
