A software developer facing a modelling task may follow different styles at different levels of abstraction and precision, to better cope with the aims and the potential users of the model. We address the problem of modelling the business processes by means of UML activity diagrams, and present five styles differing in the precision level, from the Ultra-Light style, where the nodes and the edges of the activity diagram are decorated by freely-formed text, to precise styles where instead OCL and UML actions are used. Then, we propose a practical empirical method for choosing the most suitable style depending on the context in which the models will be used (why, when, where, how long, by whom).
Business Process Modeling for developing Process Oriented IT Systems
2004
Information system developers are challenged to develop systems that should meet the requirements of modern organizations. By promoting the enterprise-wide integration, the paradigm of Business Process Management contrasts with traditional information system development. The latter was suffered, but also crystallized, the vertical division of the enterprise activities. In addition, the paradigms of Business Process Reengineering and Improvement contrast with traditional information system development that focused on automating and supporting existing business processes. Now, enterprises should create new ways of working to survive in a competitive environment. In this context, enterprise modeling can help understanding the current business situation and establishing a vision of what the future should be like. Therefore, business process modeling becomes a prerequisite for system requirements elicitation and system development.
Business processes in technology and information services
Universidad & Empresa, 2019
En este trabajo definimos y simulamos procesos en una compañía que presta servicios de tecnología de la información con el propósito de mejorar la atención y las funciones definidas en cada proceso. Analizamos diversos trabajos con respecto a la gestión de procesos de negocios y simulación. Para nuestro modelo de desarrollo, diseñamos una metodología basada en la gestión de procesos de negocios. Los procesos y las actividades fueron modelados y simulados con la ayuda de una herramienta de software para estables los tiempos y el número deposibles estancias ejecutadas. Dichos tiempos y procesos pueden ser adaptados al nivel de rendimiento deseado. El resultado de dichos procesos contribuyó a la realización de actividades de negocio de tal manera que las mismas sean más eficientes con respecto al uso del tiempo y por lo tanto otorguen un servicio de alta calidad.
Business Process Modeling in Software Development
1997
This paper is structured into two parts, dealing with notational and methodological aspects, respectively. The rst part introduces a description technique for business processes which p r o vides both an intuitive, graphical notation and a textual syntax. The de nition of semantics of this description technique is related to a mathematical system model. Using this mathematical system model as a common formal basis, the relation between business process model and other models employed in software development can be precisely de ned. In the second part, a business process driven method of software development is outlined, as well as a systematic approach to business process reengineering. As software development and business process reengineering are closely related and often occur together in practice, these two approaches will be integrated into a method which systematically combines both techniques.
Towards a Framework for Evaluating Usability of Business Process Models with BPMN in Health Sector
Procedia Manufacturing, 2015
The importance of the analysis, modelling and management of a business process is not restricted to a specific enterprise sector. In the field of health management, as a result of the nature of the service offered, health institutions' processes are also the basis for decision making which is focused on achieving their objective of providing quality medical assistance. Business processes in hospitals are very complex and variable. BPMN (Business Process Model and Notation) is a user-oriented language specifically designed for the modelling of business (organizational) processes. The objective of this work is to show the experience obtained in the creation of the conceptual models of certain hospital processes which can be used as a basis for others in collaboration with hospitals in order to model their processes using BPMN. In first instance, the processes were modeled with purposes to apply metrics for measuring the usability as a software quality attribute according to standard ISO 9126. The next challenge is to evaluate the usability of the models from the point of view of the user according to standard ISO 9241-11 that defines usability as "the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use". Starting from usability engineering, a proposal of a framework that considers evaluation criteria about previously modeled processes with BPMN results necessary. In order to achieve the framework are considered studies on the usability evaluation for business process modeling tools and languages.
Representing business processes: conceptual model and design methodology.
2009
In this work we present our contributions to business processes modeling. Namely, we have undertaken a thorough analysis of the OMG standard BPMN, along with other related technologies like WS-BPEL and XPDL. Such analysis has pointed out several weaknesses that motivate our contributions. We propose a new conceptual model of BPMN called BPeX as a clear and principled way to represent and reason about business processes. We provide a three-phase design methodology to model business processes focusing on BPMN and we introduce the notion of business process normal form. We introduce also the concept of business process views and apply them to business processes access control. Finally, we provide an extension to BPMN with privacy policies. Relevant parts of BPMN conceptual model will be included as part of the forthcoming BPMN 2.0 standard.
Analysis and Improvement of Business Process Models Using Spreadsheets
Software in general is thoroughly analyzed before it is released to its users. Business processes often are not – at least not as thoroughly as it could be – before they are released to their users, e.g., employees or software agents. This article ascribes this practice to the lack of suitable instruments for business process analysts, who design the processes, and aims to provide them with the necessary instruments to allow them to also analyze their processes. We use the spreadsheet paradigm to represent business process analysis tasks, such as writing metrics and assertions, running performance analysis and verification tasks, and reporting on the outcomes, and implement a spreadsheet-based tool for business process analysis. The results of two independent user studies demonstrate the viability of the approach.
Business processes modelling, transformation and realization
Brief characteristics of business processes (BP) is made, BP conceptual and mathematical models are suggested as one of basics for their analysis and realization methods development, which includes BP modeling and analysis, BP model transformation to computational processes (CP) model, and CP realization. The suggested models and algorithms allows to raise the efficiency of BP modeling, analysis, realization and reengineering, improving the technology of Internet-based information system (IBIS) development and reduce human factor effect on development process.
