  • Swimming Upstream in Turbulent Waters: Auditing Agile Development
    Global Business Expansion, 1
    Co-Authors: Priyadarsini Kannan Krishnamachariar, Manish Gupta

    Abstract:

    Agile Approach is a pragmatic fashion of software development, wherein the requirements are flexible to the changing needs of the customers, fast paced markets and the iterations of software are implemented and delivered based on business priorities. A risky or experimental project where the project requirements are not clear/not defined well in advance, are the most suitable candidates for adopting Agile Approach, as Agile enables us to work with calculated risks during development, aiming to reduce the risks. The value of any implementation is realized only if it delivers benefits to organization and users, which could be assured by effective auditing of the implementation by understanding the implications of Agile Approach and figuring out right audit techniques and processes. Many organizations already have well established audit functions and matured IT Audit procedures for auditing traditional SDLC waterfall processes. Yet the methods for auditing software development based on Agile Approach requires a different attitude and audit techniques that goes well with the proactive nature of Agile Approach. This paper aims to present risk based audit Approach on the Agile implementation of software development, how risk identification and assessment can be merged along with the phases of software development and the ways by which Agile techniques can be effectively utilized as tools for audit.

  • Pragmatic web service design: An Agile Approach with the service responsibility and interaction design
    method
    Computer Science – Research and Development, 2009
    Co-Authors: David E Millard, Yvonne Howard, Noura Abbas, Hugh C. Davis, Lester Gilbert, Gary Brian Wills, Robert J. Walters

    Abstract:

    Service-Oriented Architectures (SOAs) are increasingly deployed to achieve distributed systems that are modular, flexible and extensible. However, designing for SOA can be challenging; there are issues involving the granularity of the cooperating services, problems with proprietary data models being exchanged, and there are no currently accepted conventions for describing a service or its interactions at an abstract level. This paper gives an overview of the Service Responsibility and Interaction Design Method (SRI-DM), an Agile Approach for engineering a Web Service design based on capturing a scenario as a use-case, factoring this into a set of Service Responsibility and Collaboration Cards, and constructing a Sequence diagram illustrating their interactions in fulfilling the scenario. Through two case studies the paper shows how using SRI-DM can expose many of the problems of over-engineering SOA and help to create simpler, more pragmatic web service designs.

  • ECOWS – The Service Responsibility and Interaction Design Method: Using an Agile Approach for Web Service Design
    Fifth European Conference on Web Services (ECOWS'07), 2007
    Co-Authors: David E Millard, Robert J. Walters, Yvonne Howard, Noura Abbas, Hugh C. Davis, Lester Gilbert, Gary Wills

    Abstract:

    Service-Oriented Architectures (SOAs) are increasingly deployed to achieve distributed systems that are modular, flexible and extensible. Designing for a SOA can be difficult, however. There are issues involving the granularity of the cooperating services, and there are no currently accepted conventions for describing a service or its interactions at an abstract level. This paper presents the Service Responsibility and Interaction Design Method (SRI-DM), an Agile Approach for engineering a Web Service design, based on capturing a scenario as a use-case, factoring this into a set of Service Responsibility and Collaboration Cards, and constructing a Sequence diagram illustrating their interactions in fulfilling the scenario. The paper presents the notation for each step and describes with the aid of an example how this process is used to create a service design within the domain of e-assessment.
