Flexible coordination techniques for dynamic cloud service collaboration

The provision of individual, but also composed services is central in cloud service provisioning. We describe a framework for the coordination of cloud services, based on a tuple‐space architecture which uses an ontology to describe the services. Current techniques for service collaboration offer limited scope for flexibility. They are based on statically describing and compositing services. With the open nature of the web and cloud services, the need for a more flexible, dynamic approach to service coordination becomes evident. In order to support open communities of service providers, there should be the option for these providers to offer and withdraw their services to/from the community. For this to be realised, there needs to be a degree of self‐organisation. Our techniques for coordination and service matching aim to achieve this through matching goal‐oriented service requests with providers that advertise their offerings dynamically. Scalability of the solution is a particular concern that will be evaluated in detail

Integrating the goal and business process perspectives in information system analysis

There are several motivations to promote investment and scientific effort in the integration of intentional and operational perspectives: organisational reengineering, continuous improvement of business processes, alignment among complementary analysis perspectives, information traceability, etc. In this paper we propose the integration of two modelling languages that support the creation of goal and business process models: the i* goal-oriented modelling method and Communication Analysis, a communication-oriented business process modelling method. We describe the methodological integration of the two modelling methods with the aim of fulfilling several criteria: i) to rely on appropriate theories; ii) to provide abstract and concrete syntaxes; iii) to provide scenarios of application; and iv) to develop tool support. We provide guidelines for using the two modelling methods in a top-down analysis scenario. We also present an illustrative case that demonstrates the feasibility of the approach.Peer ReviewedPostprint (author's final draft

An Assessment Tool for Bank Industrialisation - Challenges and Opportunities for Business Process Management

This paper presents an assessment tool for bank industrialisation and highlights the results of an actual European Retail Banking Market Survey. Basis for bank industrialisation is a professional business process management. Due to the implementation of industrialisation methods banks expect an increase in efficiency and organisational performance. Results from an European Banking Survey shows that one of the banks’ greatest weaknesses is the low maturity level of the internal business process management. From the banks perspective the main challenges are the high effort for process modelling as well as the evaluation of the industrialisation maturity and the missing experience in using industrialisation methods and instruments. Therefore, the assessment tool enables banks to evaluate their organisational readiness for industrialisation and gives recommendations for the use of suitable industrialisation methods. The tool support banks to identify potentials due to industrialisation and help to increase organisational performance

Evaluating Business Process Improvement Patterns by Simulation

Existing approaches for business process improvement often lack systematic guidelines to transform a business process into an enhanced state, which we refer to as the “act of improvement”. To close this gap, a pattern-based approach has been designed and developed in previous works. In this paper, the usefulness of “Business Process Improvement Patterns” (BPI-Patterns) as a means of improving business processes is analyzed. For this purpose, a simulation experiment is performed in which several BPI-Patterns are applied to evaluate whether their anticipated effects can be confirmed for real-life business processes. From the analysis of the simulation results, i.e. how the application of BPI-Patterns affects the business processes, we investigate enabling as well as hindering factors that influence the implementation of BPI-Patterns. These factors may serve as a means to further specify instances of BPI-Patterns and also contribute to the overall evaluation of the BPI-Pattern approach

GoBIS: An integrated framework to analyse the goal and business process perspectives in information systems

[EN] Context Organisational reengineering, continuous process improvement, alignment among complementary analysis perspectives, and information traceability are some current motivations to promote investment and scientific effort for integrating goal and business process perspectives. Providing support to integrate information systems analysis becomes a challenge in this complex setting. Objective The GoBIS framework integrates two goal and business process modelling approaches: i⁎ (a goal-oriented modelling method) and Communication Analysis (a communication-oriented business process modelling method). Method In this paper, we describe the methodological integration of both methods with the aim of fulfilling several criteria: i) to rely on appropriate theories; ii) to provide abstract and concrete syntaxes; iii) to provide scenarios of application; iv) to develop tool support; v) to provide demonstrable benefits to potential adopters. Results We provide guidelines for using the two modelling methods in a top-down analysis scenario. The guidelines are validated by means of a comparative experiment and a focus-group session with students. Conclusions From a practitioner viewpoint (modeller and/or analyst), the guidelines facilitate the traceability between goal and business process models, the experimental results highlight the benefits of GoBIS in performance and usability perceptions, and demonstrate an improvement on the completeness of the latter having an impact on efficiency. From a researcher perspective, the validation has produced useful feedback for future research.This work has been supported by the Spanish MICINN Project ProS-Req (TIN2010-19130-C02-01, TIN2010-19130-C02-02) and EOSSAC (TIN2013-44641-P); the Generalitat Valenciana Project IDEO (PROMETEOII/2014/039); the FPI-UPV Pre-Doctoral Grant; the European Commission Project CaaS (FP7 611351); and the ERDF Structural Funds.Ruiz Carmona, LM.; Costal, D.; España Cubillo, S.; Franch, X.; Pastor López, O.

Identification of Critical Business Processes: A Proposed Novel Approach

Critical Business Processes (CBPs) are processes that are crucial to the financial stability and operations of an organisation. This paper focuses on surveying the literature, while presenting a critical synthesis of the findings of previous studies on CBPs. The paper seeks to extensively and critically review the current literature to understand state-of-the-art methods and key research gap for CBP identification. While this paper targets the process of identifying the gap in literature, it helps in finding out what is needed for mitigating it, motivating the future researches in this area, and pushing the boundary between human and machine interaction in key strategic decisions for organisations along with security implications
