The construction of a CIB cross-impact matrix will be described with the help of a simple example. The example describes a fictitious country "Somewhereland" with six interdependent factors in the fields of politics, economy and society. The steps of the CIB process are as follows:
1) Compile a list of the most relevant system factors ("descriptors").
In our example the list of descriptors contains the factors:
B. Foreign policy
D. Distribution of wealth
E. Social cohesion
F. Social values
This example represents a rather small CIB matrix. Usually a CIB analysis comprises 10-20 descriptors (and occasionally more).
2) Define a set of qualitative states which characterize the possible states of the descriptors.
(The number of states may differ from descriptor to descriptor)
Considering the fictitious country "Somewhereland" the following list of descriptor states may be used as an example: A. Government:
A1 "Patriots party"
A2 "Prosperity party"
A3 "Social party" B. Foreign policy:
B3 Conflict C. Economy:
C3 Dynamic D. Distribution of wealth:
D2 Strong contrasts E. Social cohesion:
E1 Social peace
E3 Riots F. Social values:
3) Make a judgement about the impact of state x of descriptor X on state y of descriptor Y, based on literature reviews, expert interviews, or other appropriate investigations.
Only direct influences must be accounted for these judgements. The resulting indirect influences will be automatically constructed by the CIB algorithm.
Express your judgement in a qualitative scale as follows:
In our example we may conclude that the occurence of riots will strongly motivate many citizens of Somewhereland to retreat mentally into their closer social references: the family. Therefore, +3 is chosen for the cross-impact of the state "E3 Social cohesion: Riots" on the state "F3 Social values: Family".
This procedure results in a cross-impact matrix. Fig. 2 shows the matrix for our example. The data of the matrix don't attempt to express a real situation and should be understood as an example.
