By the formula (6.10), rating points of software products and the obtained results
are summarized in Table 6.8.
Upon the experts' agreement the weight coefficients

equal to 1/3.
The obtained rating points of software products were used to develop
managerial instructions aimed at achieving future success of software products
[228—230].
Values of rating points are grouped in three intervals [0; 0.2], [0.2; 0.6],
[0; 6.1], to which linguistic values: "low", "mean", "high" are assigned,
accordingly.

If the rating point of software product falls in the first interval [0; 0.2], the
software product comes back to the beginning of previous development cycle. If
the rating point of software product falls in the last interval [0.6; 1], the software
product is transferred to the next development cycle. If the rating point of software
product falls in the mean interval [0.2; 0.6], the aggregation operator of
information will be used to develop managerial instructions.
