Table 6: Identifi cation table for the class diagram
Apart from the fi tness of the individual models, Table 7 can be slightly modifi ed to
calculate the fi tness of the methods and techniques considered as sets of models. For this
purpose, we use the same conceptual model identifi cation tables as described. However, the
fi tness calculation for methods and techniques differs in that the weighted sum is calculated
considering all the conceptual models used by a given method or technique. For example,
Table 8 shows the fi tness calculation for two generic, structured and object-oriented methods,
characterized by the DFD-ER and CD-CU models, respectively.
Table 8 indicates that the best-suited method, with a fi tness of 0.71, is the object-oriented
method. This matches the results of Table 7, where the best-suited conceptual model was the
class diagram. Note, however, that this will not necessarily be true in every case.
