Abstract

Purpose

Many service-oriented software engineering (SOSE) methods from industry and academia claim their compliance with SOA and SO, but there is a lack of framework to assess the existing methods or to provide new ones. First, the paper questions: (Q1) to what extent an approach would consider the three aspect: service, composition, and management to deliver software solutions that are conformed to SO and SOA principles; (Q2) to what extent an approach would consider the aggregates of a method, including representation techniques, assisting tools, and inspection techniques to assess the delivered solution (service and composition), in addition to the process; and (Q3) to what extent an approach would consider the alignment of business and IT through the application of model-driven development by using standards such as model-driven architecture. Then, the paper compares four generic approaches: top-down, bottom-up, green-field, and meet-in-the-middle, within a framework, to highlight their strengths and weaknesses. Finally, the paper aims to propose a business-oriented approach that focuses on the value a business can add to its customers, whereby the value must be specified in a contract to be largely re-used.

Design/methodology/approach

This work develops a framework as an abstract model for SOSE generic methods. Then, it uses the framework as an analytical study to compare the generic methods and come up with research issues and a new method for SOSE.

Findings

A set of guidelines that a SOSE method develops should consider when selecting or developing a new method.

Research limitations/implications

Comparison of existing SOSE methods within the findings of the proposed framework. The paper has theoretical implications as the open issues provide a research roadmap towards the realization of SOA in accordance with a maturity model.

Practical implications

This has practical implications as it: provides a better understanding of the approaches, as they are ambiguously used by the existing methods; and assists developers in deciding an approach having the necessary knowledge related to its process, strengths and weaknesses.

Originality/value

None of the existing comparison framework has raised the level of abstraction up to generic methods such as top-down, green-filed, meet-in-the-middle and bottom-up.

Abstract

Purpose

The purpose of this paper is to consider the method engineering perspective for service-oriented system engineering (SOSE). A number of SOSE methods have been proposed in both academia and industry. Given this, many intuitive, common questions arise. To answer these questions, many comparison frameworks have been developed. Each of which has considered certain methodological perspectives. However, less attention has been given to the method engineering (ME) perspective. The authors argue that this perspective would answer the question “what ME to apply in order to produce SOSE methods that themselves produce quality services at different levels of abstraction and SBAs”. This research question is further decomposed into other questions; the main one is “whether the existing ME do apply to service orientation”. Answering such a question would lead to either developing SOSE methods by using the existing ME or developing a new ME or framework for the specifics of SOSE.

Design/methodology/approach

This work first provides a literature review on ME approaches and techniques; then, it compares a sample of existing SOSE methods with respect to their ME within a comparison framework that comprises a set of relevant properties of a solution that would be provided by an SOSE method, namely, service-oriented architecture (SOA) adoption, quality of services and ME; and finally, it discusses the applicability of the existing ME to SOSE.

Findings

Strengths and weaknesses of the existing methods with respect to the aforementioned criteria, in addition to SOSE methodology open issues, were identified. The comparison has shown that while the existing SOSE methods have proved their success in a specific task, they still present some weaknesses. Therefore, it is better to benefit from the advantages of the existing ME techniques, notable method fragments, even if they need some alteration.

Research limitations/implications

While this work has many open issues related to SOSE methods with respect to ME, it could be further developed in many directions by exploring the open issues. For instance, the generation of a new ME technique and application of this new ME technique to the existing SOSE methods to see to what extent the existing methods may be situational.

Practical implications

This work has practical implications, as it provides a better understanding of different views of SOSE methods, and assists the method engineers in deciding which ME technique is most suitable to their situation.

Social implications

The produced artifact provides a research roadmap toward SOSE ME.

Originality/value

None of the existing comparison frameworks for SOSE methods has considered the criteria such as SOA adoption and ME techniques. Indeed, ME techniques and approaches would allow better reuse of the existing proven fragments of methods.

Abstract

Purpose

This paper aims to propose a service-oriented framework for performing content annotation and search, adapted to the task context. Media production workflows are becoming increasingly distributed and heterogeneous.The tasks of professionals in media production can be supported by automatic content analysis and search and retrieval services.

Design/methodology/approach

The processes of the framework are derived top-down, starting from business goals and scenarios in audiovisual media production. Formal models of tasks in the production workflow are defined, and business processes are derived from the task models. A software framework enabling the orchestrated execution of these models is developed.

Findings

This paper presents a framework that implements the proposed approach called Metadata Production Management Framework (MPMF). The authors show how a media production workflow for a real-world scenario is implemented using the MPMF.

Research limitations/implications

The authors have demonstrated the feasibility of a model-based approach for media processing. In the reification step, there is still information that needs to be provided in addition to the task models to obtain executable processes. Future research should target the further automation of this process.

Practical implications

By means of this approach, the implementation of the business process defines the workflow, whereas the services that are actually used are defined by the configuration. Thus, the processes are stable and, at the same time, the services can be managed very flexibly. If necessary, service implementations can also be completely replaced by others without changing the business process implementation.

Originality/value

The authors introduce a model-based approach to media processing and define a reification process from business-driven task models to executable workflows. This enables a more task-oriented design of media processing workflows and adaptive use of automatic information extraction tools.

Abstract

Purpose

This study aims to identify the level of security from existing work, analyze categories of security as a service (SECaaS) and classify them into a meaningful set of groups. Further, the report will advise commercial applications and advice of SECaaS as an extended context to help firms make decisions.

Design/methodology/approach

This paper compares the SECaaS categories in Cloud Security Alliance (CSA) with the security clauses in ISO/IEC 27002:2013 to give a comprehensive analysis of those SECaaS categories. Reviewed from a number of related literature, this paper analyzes and categorizes SECaaS into three major groups including protective, detective and reactive based on security control perspectives. This study has discussed the three groups and their interplay to identify the key characteristics and problems that they aim to address.

Findings

This paper also adds new evidence to support a better understanding of the current and future challenges and directions for SECaaS. Also, the study reveals both the positive and negative aspects of SECaaS along with business cases. It advises on various sizes and domains of organizations to consider SECaaS as one of their potential security approaches.

Originality/value

SECaaS has been demonstrated to be one of the increasingly popular ways to address security problems in Cloud computing. As a new concept, SECaaS could be treated as integrated security means and delivered as a service module in the Cloud. However, it is still in infancy and not very widely investigated. Recent studies suggest that SECaaS is an efficient solution for Cloud and real industries. However, shortcomings of SECaaS have not been well-studied and documented. Moreover, reviewing the existing research, researchers did not classify the SECaaS-related categories.

Abstract

Purpose

This paper aims to present Long4Cloud (long-running workflows execution environment for cloud), a distributed and adaptive LRW execution environment delivered “as a service” solution.

Design/methodology/approach

LRWs last for hours, days or even months and their duration open the possibility of changes in business rules, service interruptions or even alterations of formal regulations of the business before the workflow completion. These events can lead to problems such as loss of intermediary results or exhaustion of computational resources used to manage the workflow execution. Existing solutions face those problems by merely allowing the replacement (at runtime) of services associated with activities of the LRW.

Findings

LONG4Cloud extends the previous works in two main aspects, namely, the inclusion of dynamic reconfiguration capabilities and the adoption of an “as a service” delivery mode. The reconfiguration mechanism uses quiescence principles, data and state management and provides multiple adaptive strategies. Long4Cloud also adopts a scenario-based analysis to decide the adaptation to be performed. Events such as changes in business rules or service failures trigger reconfigurations supported by the environment. These features have been put together in a solution delivered “as a service” that takes advantage of cloud elasticity and allows to better allocate cloud resources to fit into the demands of LRWs.

Originality/value

The original contribution of Long4Cloud is to incorporate adaptive capabilities into the LRW execution environment as an effective way to handle the specificities of this kind of workflow. Experiments using current data of a Brazilian health insurance company were carried out to evaluate Long4Cloud and show performance gains in the execution of LRWs submitted to the proposed environment.

Abstract

Purpose

Similar to many business processes, waiting times are also essential for health care processes, especially in obstetrics and gynecology outpatient department (GOD), because pregnant women may be affected by long waiting times. Since creating process models manually presents subjective and nonrealistic flows, this study aims to meet the need of an objective and realistic method.

Design/methodology/approach

In this study, the authors investigate time-related bottlenecks in both departments for different doctors by process mining. Process mining is a pragmatic analysis to obtain meaningful insights through event logs. It applies data mining techniques to business process management with more comprehensive perspectives. Process mining in this study enables to automatically create patient flows to compare considering each department and doctor.

Findings

The study concludes that average waiting times in the GOD are higher than obstetrics outpatient department. However, waiting times in departments can change inversely for different doctors.

Research limitations/implications

The event log was created by expert opinions because activities in the processes had just starting timestamp. The ending time of activity was computed by considering the average duration of the corresponding activity under a normal distribution.

Originality/value

This study focuses on administrative (nonclinical) health processes in obstetrics and GOD. It uses a parallel activity log inference algorithm (PALIA) to produce process trees by handling duplicate activities. Infrequent information in health processes can have critical information about the patient. PALIA considers infrequent activities in the event log to extract meaningful information, in contrast to many discovery algorithms.

Abstract

E‐business information systems are computer applications that leverage intra‐ and inter‐firm process and systems integration. Considering the growth and strategic importance of e‐business, while it is important for organizations to carefully plan for and architect e‐business systems, none of the existing information systems planning models is adequate for the task. An e‐business architecture planning model is developed by identifying 12 generic e‐business models and three axes on which drivers of the information architecture needs of e‐business firms fall. Sowa and Zachman’s information architecture is augmented to further facilitate e‐business information systems architecture planning.

Abstract

In the 1990s, companies focused on the design and implementation of their internal business processes to overcome functional barriers. The 2000s are about the integration between enterprises and inter‐enterprise processes, particularly the improvement of supply chain management and customer relationship processes, The major enabler is the Internet, which has resulted in entire networks of e‐business processes across various organizations. To design and implement those processes efficiently and effectively, more and more organizations use available industry standards in the form of reference models, e.g. the supply chain reference model (SCOR), the RosettaNet Standards, or software reference models. Unclear for many enterprises is how to use those standards. This article describes a comprehensive methodology for the use of reference models, to design and implement inter‐enterprise collaborations within value chain networks. The methodology leads to fast and reliable results in value chain improvement. It increases the performance of the implementation procedure and the resulting business processes.

Abstract

A fundamental approach to setting up an e‐business initiative is needed to fully utilise the capabilities of Internet technology in a specific business setting. Such an initiative has to build on the strengths of the organisation and take full advantage of the opportunities in the market, meanwhile identifying costly unsuccessful projects and preventing unwanted market disturbances introduced by carelessly designed e‐commerce solutions. In this paper, a method is presented for the development of an e‐business, based on research in the area of strategic information systems planning. The proposed method is designed to help clarify a strategic e‐business vision and to solicit management commitment to change and take action on new business opportunities. In addition, it takes into account the unique possibilities of an organisation’s IT architecture, thus further advancing the value of past investments in IT.
