Adapting Riva to Support Case Strategy Processes and Enable Modeling a Generalized Business Process Architecture

Riva is a business process architecture (BPA) modeling approach that has been used within the software engineering domain to model key business processes for specific organizational boundaries. Also, Riva is mainly a facilitated approach that relies heavily on interactions with stakeholders to determine the key entities that constitute the foundation of modeling a BPA-of-interest, especially in its early stages. Accordingly, Riva is not considered an independent approach (without heavy interaction with stakeholders), nor is it applied to support the derivation of generalized BPA models from multiple heterogeneous sources. Furthermore, while deriving business processes from the identified Riva entities, Riva is anticipated to identify and model Case Processes (CPs), Case Management Processes (CMPs), and Case Strategy Processes (CSPs) and their interrelationships. However, the Riva approach proposed in the literature mainly supports modeling CPs, CMPs, and their interrelationships, and lacks the support of modeling the CSPs, nor their related relationships. To address the limitations mentioned above, this paper presents an adaptation to the Riva-BPA modeling approach that enables modeling of a generalized BPA from multiple heterogeneous sources. In addition, this adaptation facilitates the identification of business processes not only based on the direct interaction with stakeholders but also by utilizing independent elicitation techniques of entities. Moreover, this paper extends Riva to model the corresponding CSPs and their related relationships. The proposed adaptation has been evaluated by experts in the domains of business process modeling and software engineering.
