# Process Automation and Blockchain in Intelligence and Investigation Units: An Approach
## 4 The Proposed Approach
### Overall Approach
#### 4.2.1 Classification of Processes (Understand)
In case of negative answers in any of the questions for an activity of a process, the potential is 0 (i.e., \(Pot(Ap)=0\)) otherwise is 1 (i.e., \(Pot(Ap)=1\)). * Activities composed of sub-processes (Case 2): for activities composed by atomic activities, the potential weight, in this case, is obtained from the product of the percentage of these activities, that is, \(Pot(Ap)=Perc(P3)\ x\ Perc(P4)\ x\ Perc(P5)\). The obtained value will be between 0 and 1. Furthermore, to calculate the priority index, we consider the transactions volume (P6) and complexity (P7). The property P6 is defined considering the average transactions performed per month by all process actors (i.e., specialists of the selected unity) divided by 30 (recommendation). For the property P7, the time it usually takes to finish the process was used [31]. In the context of the specialized units, some processes requires less than two hours to be completed, while others may take a day or more. Adapting the method proposed by [PERSON] et al. [26], two steps (tasks) are carried out to perform this analysis. In the first, the index is calculated for each activity. In the second, the results are used to calculate the expected priority index. * Task 1: For each process activity, the properties P6 and P7 are analyzed using the scale for assigning a relevance weight (SARW) model (Figure 6). Aiming at the quantification of the relevance for process automation based in the level of complexity and transaction volume, this model was \begin{table}
\begin{tabular}{c c c} \hline \hline
**Perspectives** & **Descriptions** & **Questions** \\ \hline Functional & In this perspective, performed activities and their dependences are considered, as well as the relevant flows of informational entities like data, assets, among others. & 1. What are the activities performed? 2. What are the expected input and output parameters for each activity? 3. What are the dependencies between activities? 4. What are the relevant entities informational flows? \\ \hline Behavioral & Considers the moment and the form of how processes elements are performed (e.g., sequential form) and how they control dependency information between the activities. & 1. What is the order of execution of the identified activities? 2. How does the execution take place (details of operating procedures)? \\ \hline Organizational & The responsible for the execution of the process activities are identified, as well as the adopted communication mechanisms and the place in the organization where activities are executed. & 1. Who are the people responsible for carrying out each activity? 2. How does the iteration/communication take place between the specialists involved? \\ \hline Informational & Entities specifications manipulated by the processes are identified (e.g., assets, data, among others) & 1. What are the entities manipulated by the process? 2. How is the interaction with systems/data sources (if any)? 3. What are the research standards/methodologies/techniques adopted? \\ \hline \hline \end{tabular}

Table 6: Perspectives adopted for information extraction and adopted questions examples. adapted from [PERSON] et al. [31] and [PERSON] et al. [83]. With this scale, specialists are able to analyze these properties where one of the available values (i.e., 0, 0.25, 0.5, 0.75, and 1) can be achieved (denoted by Pi(A)), and a scale value (low, moderate, and high) can be determined to each property. * Task 2: To calculate the priority index of the whole process (\(N\) activities), denoted as _Pi(Pt)_, an average of the values obtained from Task 1 is calculated (the priority index will be valued between 0 and 1). Therefore: \[Pi(Pn)=\frac{\sum_{i=1}^{N}Pi(Ai)}{n}\] (1) Finally, to obtain a list of processes subject to automation in order of priority, the final step assigns a category classification to a process based on the results of step 2 (potential evaluation) and step 3 (priority index calculation). We classified and processed a quadrant (Figure 7) based on [PERSON] et al. [26].
