Tentative Keynote Speakers


Professor Joxan Jaffar

Department of Computer Science,

National University of Singapore.

Joxan Jaffar received his B.Sc.(Hons, 1st class) and M.Sc. from Melbourne University in 1979 and 1981, and his Ph.D. from Monash University in 1985. From 1982 through 1986, he was a Lecturer in Monash, and from 1986 through 1995, he was a Research Staff Member and Project Leader in the IBM. T.J. Watson Research Center, Yorktown Heights, New York. He joined NUS in 1995, became Head of the Department of Computer Science in 1998, and Dean of the School of Computing from 2001-2007. His interests are in programming languages and applications, with emphasis on the logic and constraint programming paradigms. Amongst his main contributions are the principles of constraint logic programming, and the widely-used CLP(R) system. His current interests center around program analysis and verification, and the design of concurrent programming languages.

Symbolic Tracing for Program Reasoning

Formal reasoning about programs is a key component of software engineering. Unfortunately, present tools for program reasoning are typically limited in scope, or else they require manual aid of an expert nature. In this talk, I will present a new framework for the generation of symbolic execution traces with emphases on transparency,flexibility and increasingly, practical performance. At the heart of the framework is Constraint Logic Programming (CLP), which was originally designed as a high-level declarative programming language. In this work, we adapt and extend the concepts of CLP to focus on representing the operational behavior of programs. We then show a number of algorithms that form the basis of efficient implementation.

Today, he is focusing his experience in software engineering in the areas of education, and software product lines for embedded, ubiquitous systems. He currently serves in several boards and advisory committees including the National Science Foundation, the Software Engineering Institute, and ihe has also provided professional expertise to international organizations including the European Software Institute, Australian Defense Science and Technology Office, Kyoto Computing Gaikum, Kuwait University, Cairo University, among others.

Research Challenges for Institutionalizing Software Product Lines

The competitiveness of development organizations depends increasingly on the ability to improve their design and development processes faster than their competitors. A promising approach is to move our focus from engineering single systems to engineering families of systems by identifying “reusable” solutions that support the future development of multiple systems. An organization that focuses on a “range of similar” products can potentially take advantage of economies of scope, a benefit that comes from developing one asset used in multiple contexts, thus reducing development, maintenance, support and marketing costs, since products would share a common design, development effort, and actual components. Building systems from a common component base reduces risk and improves quality by using trusted, proven components; it reduces cycle time and cost of new applications by eliminating redundancy. An asset-based approach allows the management of legacy systems more efficiently, increasing the likelihood of longer time-IN-market. And finally, an organization based on product lines evolves a common marketing strategy, and strengthens core competency around strategic business interests and goals. Thus, the overall goal is to produce quality products consistently and predictably by moving toward an asset-supported, component-based product lines development approach. This transition must be planned carefully encompassing not only technical issues but also organizational and business aspects. Assessing the sstate-of-the-art helps in focusing the research agenda in the critical problems limiting the advancement of the field. What are the top remaining problems for SPL research? What are current top areas of SPL research? In this presentation, we address these and other questions referring to the technological challenges of building product lines. Due to space constraints however, we do not discuss specific technology in detail. Rather, we present a roadmap for the various research areas, relevance and promising approaches. We discuss briefly some of the most relevant contributions in the SPL research timeline from details of a survey we have conducted. We conclude with a discussion of the effort that lies ahead.

Paradox between Software Development Productivity and Success Rate – Are we striking the right balance?

Software systems produced in recent years are more complex and sophisticated than those of yester years. At the same time there is constant pressure to produce quality software in a shrunk cycle time due to fierce competition and rapid change in technology. Software industry in general is struggling to strike the right balance between productivity and success rate. The success rate is defined from two schools of thoughts: “Does the delivered system meet or exceed the expectations we had for it?” and “Did the system come in "up to spec," on time, and on budget?” This keynote describes an approach to achieve continuous improvement in success rate and productivity by using the combination of “Methodologies”, “Processes” and “Changing behavior pattern of software Engineers”. Undoubtedly there has been substantial amount of work in “Methodologies” and “Processes” over the years, but amalgamation of two in a way so that engineers who are developing the software can relate to and feel motivated to improve success rate and productivity, has been missing. This keynote addresses this issue, by focusing on the following:

  • Systematic inclusion of practices of Six Sigma for Product Development (SSPD) to translate the Voice of Customer (VOC) into measurable Requirements. Historical data have shown that errors in requirements contribute to a consistent, absolute project failure rate (~50%) that can’t be reduced.
  • Critical KPIs from CMMi (QPM and PP) to ensure project life cycle remains predictable.
  • Use of “Agile” methodology for development to ensure motivation of engineers remains high at the same time generating better productivity and low defect density in turn resulting into high probability of success rate.
