Example 4.3. Building of an optimum linguistic scale for the software
completeness evaluation.
For defining the optimum set of the linguistic scale used to
estimate the software completeness, five experts generated three ranges of this scale:
1.
“incompleteness”, “partial completeness”, “complete completeness”;
2.
“incompleteness”, “partial completeness”, “ basic completeness”, “complete
completeness”:
3.
“incompleteness”, “partial completeness”, “basic completeness”, “essential
completeness”, “complete completeness”.
To estimate a characteristic “complete completeness” which characterizes degree
of the software possession, all necessary parts and features required for carrying
out its explicit and implicit functions, 25 software products for supporting
financial activity of firms was chosen (Table 4.3).
Results of the software completeness evaluation made by five experts within
the limits of a linguistic scale "incompleteness", “partial completeness", “basic
completeness”, “complete completeness” are summarized in Table 4.4.
Based on the method described in § 2.2 and data of Table 4.4, membership
functions of term-sets of five COSS's (models of expert evaluations of software
completeness) the graphs of which are represented in Fig. 4.3, were obtained.
Using definitions of §3.1, an additive index
of the general consistency of

was calculated,
respectively. Based on the obtained values
the conclusion was drawn on a sufficient consistency of models of expert
evaluations of software completeness.
