An Introduction to Requirements Traceability

This report surveys the requirements traceability literature and gives some recommendations for further research and for an approach to consultancy concerning traceability in the 2RARE project. The problem of maintaining traceability in a development project is viewed as the problem of maintaining an information system that maintains the relevant links between items developed during the process. These items may vary from requirements to design and implementation documents. To develop and implement such an information system, we must identify the needs for tracking information, made a model of this information, design usage procedures for the system, and implement the system. Accordingly, the literature on traceability is organized under the headings needs, models and usage. Furthermore, tracking tools are briefly reviewed

A Conceptual Basis for Feature Engineering

The gulf between the user and the developer perspectives lead to diculties in producing successful software systems. Users are focused on the problem domain, where the system's features are the primary concern. Developers are focused on the solution domain, where the system's life-cycle artifacts are key. Presently, there is little understanding of how to narrow this gulf

Factors shaping the evolution of electronic documentation systems

The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments

Collected software engineering papers, volume 6

A collection is presented of technical papers produced by participants in the Software Engineering Laboratory (SEL) during the period 1 Jun. 1987 to 1 Jan. 1989. The purpose of the document is to make available, in one reference, some results of SEL research that originally appeared in a number of different forums. For the convenience of this presentation, the twelve papers contained here are grouped into three major categories: (1) Software Measurement and Technology Studies; (2) Measurement Environment Studies; and (3) Ada Technology Studies. The first category presents experimental research and evaluation of software measurement and technology; the second presents studies on software environments pertaining to measurement. The last category represents Ada technology and includes research, development, and measurement studies
