Challenges and Approaches to Engaging Stakeholders in Requirements Engineering
This event took place on Tuesday 25 October 2005 at 12:15

 
Prof. Pericles Loucopoulos Information Systems Group, School of Informatics, the University of Manchester, UK

A key challenge in the development of systems is the engagement of domain experts in their articulation, agreement, and validation of requirements. This challenge is particularly pronounced at the early requirements phase when multiple stakeholders from different divisions and often different organisations need to reach agreement about the intended systems. Decisions taken at this stage have a profound effect on the technical and economic feasibility of a project. The response of the Requirements Engineering community has been the introduction of a variety of conceptual modelling formalisms and appropriate requirements engineering processes. There is sufficient empirical evidence however that demonstrates the alienation of stakeholders from such notations and processes. The possible acquiescence of stakeholders approving a specification, without a deeper understanding of the modelled system, can lead to potentially profound problems due to differences between the expected value from the target system and that which is finally delivered. This talk will explore issues, challenges and approaches associated with capturing of, negotiating about and agreeing on early requirements from a design stance, using examples from large scale industrial applications.

Future Internet is...


Future Internet
With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

  • Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

  • Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection

  • Interoperability of semantic data and metadata, and of services which will be dynamically orchestrated

  • Pervasive usability for users of mobile devices, different languages, cultures and physical abilities

  • Mobility for users who expect a seamless experience across spaces, devices, and velocities
