as “1” are included in antecedent set. The intersection set represents the common
values of reachability and antecedent sets. Finally, the levels are decided for a
variable if for that particular variable, both reachability set and intersection set is
common. For better understanding of level partitioning, Table 8.6 represents the
level partitioning of various barriers (Tables 8.7, 8.8, and 8.9).
This level partitioning is used to construct the hierarchical structure as
represented in Fig. 8.3.
The values obtained through driving and dependence power of each of the barrier
are used to plot a graph for MICMAC analysis, where driving power is plotted on
X-axis and dependence power on Y-axis as shown in Fig. 8.2.
All the barriers above the half of Y-axis (i.e., top two quadrants) are considered to
have high driving power on the whole system. Especially the barriers in the top left
quadrant have very high driving power and low dependence power and are considered most important for the system. In this case lack of technologies (BI09) is the
only barrier in top left quadrant and hence has the most impact on the whole system
(Fig. 8.3).
