“…Teichroew and his team of Ph.D. students had invented CASE, a set of technologies and processes for developing high quality code. The team continued the to make substantial progress on CASE tools for many years [67]. Nunamaker, however, remained focused on the question of how a systems analyst could bring 4000 stakeholders to consensus around the requirements for a large, complex system without having to hire consultants to sit with each stakeholder and write PSL.…”

From our desk chairs it may be tempting to work up an idea, build a quick prototype, test it in a lab, and say, "Our work here is done; the rest is merely details." More scholarly knowledge awaits discovery, however, by researchers who shepherd an information systems (IS) solution through the last research mile, that is, through successful transition to the workplace. Going the last research mile means using scientific knowledge and methods to address important unsolved classes of problems for real people with real stakes in the outcomes. The last research mile proceeds in three stages: proof-of-concept research to demonstrate the functional feasibility of a solution; proof-of-value research to investigate whether a solution can create value across a variety of conditions; and proof-of-use research to address complex issues of operational feasibility. The last research mile ends only when practitioners routinely use a solution in the field. We argue that going the last research mile negates the assumption that one must trade off rigor and relevance, showing it to be it a false dilemma. Systems researchers who take their solutions through the last research mile may ultimately have the greatest impact on science and society. We demonstrate the last research mile with cases from our own work and the work of others spanning more than forty years. As a professor of information systems at San Diego State University, Robert O. Briggs researches the cognitive foundations of collaboration and uses his findings to design new collaborative work practices and technologies. He is cofounder of the collaboration engineering field and co-inventor of the ThinkLets design pattern language for collaborative work processes. He has made exploratory, theoretical, experimental, and technological contributions to the areas of team productivity, technology-supported learning, ideation, creativity, consensus, satisfaction, willingness to change, and technology transition. He has designed collaboration systems and collaborative workspaces for industry, academia, government, and the military. He co-chairs the Collaboration Systems and Technology track for the Hawaii International Conference on System Sciences. He lectures worldwide on collaboration theory and practice, and on the logic of scientific inquiry. He has published more than two hundred scholarly works collaboration systems and technology, addressing issues team productivity, technology-supported learning, creativity, satisfaction, and technology transition. He earned his doctorate Management Information Systems at the University of Arizona in 1994. Air Force officer. He has extensive experience working with the Department of Defense. As a contractor and academic, he has been awarded contracts and grants totaling $39.85 Million over the last 12 years (principle investigator awards total $16.89 Million).

“…The tools and methods of the time permitted and assisted in the organization of the requirements, refinement of details, consistency checking, preparation of the specification, and in some cases, formalization of these requirements (Alford, 1977;Ross, 1977;Teichroew, 1977;Alford, 1978;Zave, 1982;Burstin, 1984;Alford, 1985;Borgida, 1985;Sievert, 1985;Estrin, 1986). Some of these tools also provided a means to relate design and implementation artifacts to their individual requirements to assist in the eventual validation of the realization of the requirements.…”

Abstract. Abstraction identification is named as a key problem in requirements analysis. Typically, the abstractions must be found among the large mass of natural language text collected from the clients and users. This paper motivates and describes a new approach, based on traditional signal processing methods, for finding abstractions in natural language text and offers a new tool, AbstFinder as an implementation of this approach. The advantages and disadvantages of the approach and the design of the tool are discussed in detail. Various scenarios for use of the tool are offered. Some of these scenarios were used in case study of the effectiveness of the tool on an industrial-strength example of finding abstractions in a request for proposals.
