Paper is in open access: http://bit.ly/2c3RI8P This paper suggests a new type of enterprise models called fractal enterprise models (FEM), with accompanying methodological support for their design. FEM shows interconnections between the business processes in an enterprise by connecting them to the assets they use and manage. Assets considered in th...

The Fractal Process-Asset (FPA) model has been proposed as an approach for identifying business processes and defining relationships between them in an enterprise. This paper reports on a project of applying the model in a Higher Education Institution enterprise. The goal of this project is twofold. One is to design a process architecture that prov...

A promising approach for analyzing and designing an enterprise is to consider it as a complex adaptive system (CAS) able to self-adjust to the changes in the environment. An important part of designing a CAS model is to untangle the dynamic structure of an enterprise. This paper presents a procedure for identifying all processes that exist in an en...
Conference Paper
CPSAM is a context-based process semantic annotation model for annotating business processes in a process model repository. The purpose of the annotation model is to facilitate searching process models, navigating a process model repository and enhance users' understanding of process models. The annotation model has partly been evaluated through an...
Conference Paper
Business process modeling is a complex, time consuming and error prone task. However the efforts made to model business processes are seldom reused beyond their original purpose. Rather than modeling of business processes from scratch, analysts can drive process models, by redesigning the existing ones. A repository is, therefore, necessary to stor...

Reuse of business process models is the act of designing business processes by using existing process models. Reuse of business process models has been considered as a way to reduce the cost of modeling business processes from scratch. In order to support reuse a critical mass of process models is required which justifies the effort of maintaining...

Today reuse of business process models is becoming increasingly important. One of the proven solutions for reusing business process models is the use of repositories. Repositories should have process models and process metadata that can help users in searching, understanding, and interpreting process models. The purpose of this paper is to propose...

Process model reuse is becoming a key approach to addressing the challenges of modeling business processes from scratch. A repository is, therefore, essential to store and manage process models for future reuse. In this paper, we develop a logical data model that enables a Universal Process Repository to store process models in the form of process...

... Our discussion is focused only on the cases of operational decision-making where Fractal Enterprise Model (FEM) [5] could be used ignoring other methods of conducting such decisions. FEM is employed for (1) getting a holistic picture of business activities of interest, (2) analyzing the situation, and (3) finding places in the business where some operational-level decision can or need to be made. ...
... This paper is based on an experience report Elias et al. [22] presented at the working conference for Business Process Modeling, Development and Support in 2014 (BPMDS 2014). The current paper has a more theoretical nature than the experience report, the latter being used in the paper to validate and illustrate our line of thought and findings. ...
... Also, recent works [40], [41] [42], affirm that annotating business processes with a context-based process semantic annotation model facilitates searching models, navigating the repository and enhance understandability of process models. The annotation model consists of the following annotation elements: process type, process area, resource, actor, organizational level, process phase, process relationship, business context, and goal. ...
... Quality management of the company is based on process model built a number years ago. Process model is decomposed into the six levels [4]; altogether, there are 260 process models containing 1400 tasks in the repository [5]. Process diagrams follow BPMN [6] format. ...
... The enterprise model we use for transformational purpose is called a Fractal Enterprise Model (FEM). It was first introduced at PoEM 2012 [10], and then extended and improved in [11]. FEM has a form of a directed graph with two types of nodes Processes and Assets, where the arrows (edges) from assets to processes show which assets are utilized by which processes and arrows from processes to assets show which processes help to have specific assets in healthy and working order. ...
... Shahzad et al. in [4], proposed a generic data model for storing and sharing process models between different modeling languages that only captures fundamental elements of a process. The generic data model is capable to store fundamental elements of a process model in a format that is independent of any process modeling language. ...
... Whereas unplanned reuse does not require any special preparation of a model to enable its later reuse, planned reuse can only be achieved by first preparing the model (e.g., documenting the model, creating metadata). A disadvantage of the unplanned reuse is that the costs of the adaptation of a comprehensive model often outweigh the benefits of reuse [12]. Hence, approaches to reuse smaller units such as labels, elements, rules or fragments [13] emerge to create new models out of existing ones. ...
... However, existing research in the context of process model comprehension addresses only objective factors. Since different kinds of stakeholders (e.g., modeling and domain experts) are involved in working with process models, their expertise in the comprehension of such models varies [16]. Interestingly, research showed that expertise in working with process models is not the only decisive factor influencing process model comprehension [17]. ...
... Here after we briefly describe the phases. In this phase a literature research was done for an overview of the key BP issues and underlined approaches reported by various researchers [15][16][17][18][19][20][21][22][23][24]. We have considered approaches, process classification schemes and BP perspectives [19] to collect a set of process model related metadata. ...
