# 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 the process classification phase, four steps/tasks are performed: the process analysis to verify what is eligible for automation; the potential analysis for automation; the calculation of the prioritization index; and the classification step. The classification helps specialists in the business area in determining the list of processes categorized by automation priority. In the validation phase for eligibility for automation, an evaluation of the process level of maturity (property P1) and standardization (property P2) is performed. The maturity evaluation considers the environment and process stability, as well as the predictability of results. For this, two questions are adopted for use by business analysts. Table 5 presents the list of properties and questions adopted in each activity of the first three classification process steps/tasks. Regarding the process standardization evaluation phase, specialists are asked to perform a validation if the [PERSON] et al. [18] process perspectives can be extracted (specifying them), checking to see if activities are carried out following the same (or similar) operational procedures. According to  
Figure 5: Illustration of the overall approach. \begin{table}
\begin{tabular}{c c c c c} \hline \hline
**Task** & **ID** & **Property** & & **Questions** \\ \hline \multirow{6}{*}{Validate Eligibility} & \multirow{6}{*}{P1} & \multirow{6}{*}{Maturity} & 1. & Are the same results (or services) been expected by specialists that interact with the processes (i.e., process objectives)? \\  & & & 2. & Is the environment of the process stable (e.g., from the point of view of business applications, platforms adopted are stable)? \\ \cline{2-5}  & & & 1. & Is the extraction and specification of the four process perspectives [18] (dynamic, behavioral, organizational, informational) possible? \\ \cline{1-1}  & & & 2. & Are activities carried out following the same (or similar) operational procedures? \\ \hline \multirow{6}{*}{Evaluate Potential} & \multirow{2}{*}{P3} & \multirow{2}{*}{Access to systems/data sources} & 1. & The processes usually require manual access to systems or data sources (multiple or individual with frequency) to be completed? \\ \cline{2-5}  & & & 1. & Is the decomposition of the business process into clearly defined sub processes possible? \\ \cline{1-1} \cline{2-5}  & & & 1. & Are the activities carried out based on well-defined business rules? \\ \cline{1-1} \cline{2-5}  & & & 1. & Are the activities carried out based on well-defined business rules? \\ \cline{1-1} \cline{2-5}  & & & & * \\ \cline{1-1} \cline{2-5}  & & & & * \\ \cline{1-1} \cline{2-5}  & & & & * \\ \hline \hline \end{tabular}

Table 5: Properties and questions adopted in each task of the classification phase. [PERSON] et al. [26], when it is possible to extract perspectives [18] clearly from the process definition, it is also possible to adopt modeling tools (e.g., business process model and notation) in the process specification [82]. Table 6 presents four perspectives and examples of questions adopted for information extraction in the context of intelligence and investigation units. For the evaluation of the potential weight of a business process to be automated, three properties were considered: if the process usually accesses systems or data sources (multiple or individual with frequency) (P3); if there is a possibility of decomposing a process into sub processes (P4); and if the activity performed is based on a pre-defined business rules (P5). According to [PERSON] et al. [83], processes activities can be atomic or non-atomic where, especially considering the two cases in measuring the potential for automation of a process [26]:  
* Atomic activities (Case 1): To make it possible to calculate the automation potential weight for the of atomic activities, a question-based approach (questions presented in Table 5) is adopted by the business analysts for the three properties.
