In order to progress through events, a function/ active event must be executed. Depending on the process flow, the function has the ability to transform event states or link to other event driven process chains.

To alleviate this issue, and shed some light on what to consider when selecting an appropriate conceptual modeling technique, the framework proposed by Gemino and Wand will be discussed in the following text. However, before evaluating the effectiveness of a conceptual modeling technique for a particular application, an important concept must be understood; Comparing conceptual models by way of specifically focusing on their graphical or top level representations is shortsighted. Gemino and Wand make a good point when arguing that the emphasis should be placed on a conceptual <a href="/wiki/Modeling_language" title="Modeling language">modeling language</a> when choosing an appropriate technique. In general, a conceptual model is developed using some form of conceptual modeling technique. That technique will utilize a conceptual modeling language that determines the rules for how the model is arrived at. Understanding the capabilities of the specific language used is inherent to properly evaluating a conceptual modeling technique, as the language reflects the techniques descriptive ability. Also, the conceptual modeling language will directly influence the depth at which the system is capable of being represented, whether it be complex or simple.<sup id="cite_ref-Gemino_and_Wand_9-0" class="reference"><a href="#cite_note-Gemino_and_Wand-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Considering_affecting_factors">Considering affecting factors</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Conceptual_model&action=edit&section=13" title="Edit section: Considering affecting factors"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Building on some of their earlier work,<sup id="cite_ref-early_Gemino_and_Wand_10-0" class="reference"><a href="#cite_note-early_Gemino_and_Wand-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> Gemino and Wand acknowledge some main points to consider when studying the affecting factors: the content that the conceptual model must represent, the method in which the model will be presented, the characteristics of the model's users, and the conceptual model languages specific task.<sup id="cite_ref-Gemino_and_Wand_9-1" class="reference"><a href="#cite_note-Gemino_and_Wand-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> The conceptual model's content should be considered in order to select a technique that would allow relevant information to be presented. The presentation method for selection purposes would focus on the technique's ability to represent the model at the intended level of depth and detail. The characteristics of the model's users or participants is an important aspect to consider. A participant's background and experience should coincide with the conceptual model's complexity, else misrepresentation of the system or misunderstanding of key system concepts could lead to problems in that system's realization. The conceptual model language task will further allow an appropriate technique to be chosen. The difference between creating a system conceptual model to convey system functionality and creating a system conceptual model to interpret that functionality could involve two completely different types of conceptual modeling languages. </p> <div class="mw-heading mw-heading4"><h4 id="Considering_affected_variables">Considering affected variables</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Conceptual_model&action=edit&section=14" title="Edit section: Considering affected variables"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Gemino and Wand go on to expand the affected variable content of their proposed framework by considering the focus of observation and the criterion for comparison.<sup id="cite_ref-Gemino_and_Wand_9-2" class="reference"><a href="#cite_note-Gemino_and_Wand-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> The focus of observation considers whether the conceptual modeling technique will create a "new product", or whether the technique will only bring about a more intimate understanding of the system being modeled. The criterion for comparison would weigh the ability of the conceptual modeling technique to be efficient or effective. A conceptual modeling technique that allows for development of a <a href="/wiki/System_model" class="mw-redirect" title="System model">system model</a> which takes all system variables into account at a high level may make the process of understanding the system functionality more efficient, but the technique lacks the necessary information to explain the internal processes, rendering the model less effective. </p><p>When deciding which conceptual technique to use, the recommendations of Gemino and Wand can be applied in order to properly evaluate the scope of the conceptual model in question. Understanding the conceptual models scope will lead to a more informed selection of a technique that properly addresses that particular model.

Conceptual models have a certain purpose in mind, hence the core semantic concepts are predefined in a so-called meta model. This enables a pragmatic modelling but reduces the flexibility, as only the predefined semantic concepts can be used. Samples are flow charts for process behaviour or organisational structure for tree behaviour. </p><p>Semantic models are more flexible and open, and therefore more difficult to model. Potentially any semantic concept can be defined, hence the modelling support is very generic. Samples are terminologies, taxonomies or ontologies. </p><p>In a concept model each concept has a unique and distinguishable graphical representation, whereas semantic concepts are by default the same. In a concept model each concept has predefined properties that can be populated, whereas semantic concepts are related to concepts that are interpreted as properties. In a concept model operational semantic can be built-in, like the processing of a sequence, whereas a semantic model needs explicit semantic definition of the sequence. </p><p>The decision if a concept model or a semantic model is used, depends therefore on the "object under survey", the intended goal, the necessary flexibility as well as how the model is interpreted. In case of human-interpretation there may be a focus on graphical concept models, in case of machine interpretation there may be the focus on semantic models. </p> <div class="mw-heading mw-heading3"><h3 id="Epistemological_models">Epistemological models</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Conceptual_model&action=edit&section=19" title="Edit section: Epistemological models"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>An epistemological model is a type of conceptual model whose proposed scope is the <a href="/wiki/Knowledge" title="Knowledge">known</a> and the knowable, and the <a href="/wiki/Belief" title="Belief">believed</a> and the believable. </p> <div class="mw-heading mw-heading3"><h3 id="Logical_models">Logical models</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Conceptual_model&action=edit&section=20" title="Edit section: Logical models"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In <a href="/wiki/Logic" title="Logic">logic</a>, a model is a type of <a href="/wiki/Interpretation_(logic)" title="Interpretation (logic)">interpretation</a> under which a particular statement is true.
