2002). The ontological model of the CO is the
conceptualization of a generic organization
considered to exist in every enterprise and responsible
for controlling its viability (Aveiro et al., 2011). That
is, the ontological model of the CO is a default subset
of the ontological model of every organization
(Aveiro, 2010; Aveiro et al., 2011).
If no applicable rules exist to deal with one
specific dysfunction, it is considered to be an
unexpected exception (Aveiro, 2010; Aveiro et al.,
2011). In this last case, a microgenesis strategy is
applied by the GO, starting an organizational
engineering process (OEP) to identify the root cause
of the dysfunction and the necessary acts to adjust the
OA and eliminate or circumvent the unexpected
exception (Aveiro, 2010; Aveiro et al., 2011),
changing the organizational self (Aveiro, 2010). This
type of exceptions must be solved with human
intervention and with innovative OA (Mourão and
Antunes, 2007). An OEP can be initiated for two
different reasons: because there is no associated and
known expected exception causing the dysfunction;
or because all resilience strategies have been tried
without success (Aveiro, 2010). In the OEP, there is
an intertwining play between three major categories
of acts: unexpected exception handling acts, OA state
changes and OA operationalization acts (Aveiro,
2010). Based on previous work (Mourão and
Antunes, 2007), Aveiro argues that all OEP starts
with the detection of an unexpected exception, that is
monitored and leads to a diagnostic (Aveiro, 2010;
Mourão and Antunes, 2007). Recovery actions may
be applied to eliminate or circumvent the unexpected
exception (Aveiro, 2010; Mourão and Antunes,
2007). In this sense, the primary purpose of the GO is
to preserve an updated organizational self and an
updated ontological model (Aveiro, 2010).
The responsibilities for the handling and follow
up of OEP should be clear (Mourão and Antunes,
2007) so that actors can stay accountable for their
decisions. According to Aveiro (2010), the actor role
‘handler of the OEP’ is crucial, as s/he coordinates the
several acts needed to change the organizational self,
either by the operationalization or discontinuation of
OA, as shown in the Actor Transaction Diagram (see
Aveiro, 2010, p. 120). The Object Fact Diagram of
OEP, under the GO, presents its classes, fact types,
and results (see Aveiro, 2010, p. 115), while the
Monitoring, Diagnosis, Exception and Recovery
Table (MDERT) consolidates the information of the
dysfunction monitoring, as well as its diagnosis (see
Aveiro, 2010, p. 117).
2.3 Analysis of Causes
To accurately detect the root cause, a detailed
assessment of the dysfunction and exception is
required (Mourão and Antunes, 2007). The diagnosis
should be an iterative process where different actors
may collaboratively contribute (Mourão and Antunes,
2007). To aid in the handling of current unexpected
exceptions, the organization should keep the record
of past monitoring, diagnosis and recovery facts.
During the diagnosis phase, the responsible agent
should review past dysfunctions related to that same
viability norm or to other norms that might have
suffered from similar exception kinds (Aveiro, 2010).
A consultation with actors that have been previously
involved in the monitoring and diagnosis of akin
dysfunctions might also help (Aveiro, 2010). The
actor's perception over the exception may change
along the iterative process of diagnostic, especially
when new facts are uncovered (Mourão and Antunes,
2007). The diagnosis, usually performed by the agent
responsible for the OEP, should collect the
information needed to detect the root cause of the
exception (Aveiro, 2010). The monitoring phase
includes the necessary actions to control the progress
of the OEP, making sure that updated information
about the exception is available to the agents that need
it (Aveiro, 2010; Mourão and Antunes, 2007).
Consequently, monitoring actions might bring
environmental information to the system (Mourão
and Antunes, 2007). During and after the diagnosis,
actors may implement different recovery actions, as
new data is obtained (Mourão and Antunes, 2007).
The information about applied recovery actions
should be kept (Mourão and Antunes, 2007). Based
on the information collected in the diagnosis phase, a
bundle of OA is generated, operationalized (or
discontinued) and approved, to solve the exception
handled by the OEP (Aveiro, 2010).
Authors argue that the concept of root cause seeks
to prevent a diagnosis from stopping too quickly
(Smith, 1998), but it should not be taken too far, as
well. Hence, it is argued that detecting the root cause
is to identify where effective action can be taken to
prevent dysfunction recurrence (Smith, 1998). The
literature presents different frameworks to detect root
causes of exceptions (Bilsel and Lin, 2012; Ishikawa,
1986; Smith, 1998). The cause-and-effect diagram by
Ishikawa is one of the most popular frameworks
(Bilsel and Lin, 2012), as it recognizes that an effect
can have more than one cause and that one cause can
provoke more than one effect. The cause-and-effect
diagram allows to group causes by categories,
