are also possible for unstructured processes. However, creating an integrated process model cov-
ering all perspectives (Stage 3) is often not possible. Instead separate models are generated for the
other perspectives, e.g., a social network

12.2 Approach

∗
In Sect. 11.3, we introduced the L life-cycle model describing an idealized process
mining project aiming at improving a Lasagna process. Only the initial stages are
applicable for Spaghetti processes. Figure 12.5 shows the most relevant part of the
∗
L life-cycle model. Note that Stage 4 has been removed because operational sup-
port is impossible for the processes just described. To enable history-based predic-
tions and recommendations, it is essential to first make the “Spaghetti-like” process
more “Lasagna-like”. In fact, Stage 3 will also be too ambitious for most Spaghetti
processes. It is always possible to generate process models as shown in Figs. 12.1
and 12.4 (Stage 2). Moreover, it is also possible to view dotted charts, create so-
cial networks, etc. However, it is very unlikely that all of these can be folded into a
meaningful comprehensive process model as the basis (the control-flow discovered)
is too weak.
