A Case Study on Software Requirements Engineering using the FBI Virtual Case File Project Report
Virtual Case File (VCF) was a case management software to be developed by the United States Federal Bureau of Investigation (FBI) to replace the existing Automated Case Support (ACS) software system. The goal of the project was to modernize FBI’s suite of investigative software applications; the ACS system was developed in-house consisting of several layers of applications that were outdated and difficult to use. Based on the Goldstein’s [1] report it was identified that the VCF system did not adhere to the requirements of the project and was fragmented. This case study identifies the critical problems from requirements engineering perspective that contributed to VCF project failure and discusses software engineering methods that would assist in requirements gathering
Flight software requirements and design support system
The desirability and feasibility of computer-augmented support for the pre-implementation activities occurring during the development of flight control software was investigated. The specific topics to be investigated were the capabilities to be included in a pre-implementation support system for flight control software system development, and the specification of a preliminary design for such a system. Further, the pre-implementation support system was to be characterized and specified under the constraints that it: (1) support both description and assessment of flight control software requirements definitions and design specification; (2) account for known software description and assessment techniques; (3) be compatible with existing and planned NASA flight control software development support system; and (4) does not impose, but may encourage, specific development technologies. An overview of the results is given

Miki: a wiki for synchronous modeling of software requirements
Eliciting a high quality requirements model that can be traced down to implementations is a challenge. Keeping models updated for evolving software systems is a further challenge. Formal modelling methods are one approach - but one that is too rigid and costly for many small software engineering companies [1]. We propose a light-weight alternative, using a wiki as the synchronous bridge between requirements capture and more formal modeling features of the IDE such as Eclipse
Onboard shuttle on-line software requirements system: Prototype
The prototype discussed here was developed as proof of a concept for a system which could support high volumes of requirements documents with integrated text and graphics; the solution proposed here could be extended to other projects whose goal is to place paper documents in an electronic system for viewing and printing purposes. The technical problems (such as conversion of documentation between word processors, management of a variety of graphics file formats, and difficulties involved in scanning integrated text and graphics) would be very similar for other systems of this type. Indeed, technological advances in areas such as scanning hardware and software and display terminals insure that some of the problems encountered here will be solved in the near-term (less than five years). Examples of these solvable problems include automated input of integrated text and graphics, errors in the recognition process, and the loss of image information which results from the digitization process. The solution developed for the Online Software Requirements System is modular and allows hardware and software components to be upgraded or replaced as industry solutions mature. The extensive commercial software content allows the NASA customer to apply resources to solving the problem and maintaining documents
Software requirements: Guidance and control software development specification
The software requirements for an implementation of Guidance and Control Software (GCS) are specified. The purpose of the GCS is to provide guidance and engine control to a planetary landing vehicle during its terminal descent onto a planetary surface and to communicate sensory information about that vehicle and its descent to some receiving device. The specification was developed using the structured analysis for real time system specification methodology by Hatley and Pirbhai and was based on a simulation program used to study the probability of success of the 1976 Viking Lander missions to Mars. Three versions of GCS are being generated for use in software error studies

Completeness, robustness, and safety in real-time software requirements specification
This paper presents an approach to providing a rigorous basis for ascertaining whether or not a given set of software requirements is internally complete, i.e., closed with respect to questions and inferences that can be made on the basis of information included in the specification. Emphasis is placed on aspects of software requirements specifications that previously have not been adequately handled, including timing abstractions, safety, and robustness
Modelling the Strategic Alignment of Software Requirements using Goal Graphs
This paper builds on existing Goal Oriented Requirements Engineering (GORE)
research by presenting a methodology with a supporting tool for analysing and
demonstrating the alignment between software requirements and business
objectives. Current GORE methodologies can be used to relate business goals to
software goals through goal abstraction in goal graphs. However, we argue that
unless the extent of goal-goal contribution is quantified with verifiable
metrics and confidence levels, goal graphs are not sufficient for demonstrating
the strategic alignment of software requirements. We introduce our methodology
using an example software project from Rolls-Royce. We conclude that our
methodology can improve requirements by making the relationships to business
problems explicit, thereby disambiguating a requirement's underlying purpose
and value.Comment: v2 minor updates: 1) bitmap images replaced with vector, 2) reworded

Towards a document structure editor for software requirements analysis
Of the six or seven phases of the software engineering life cycle, requirements analysis tends to be the least understood and the least formalized. Correspondingly, a scarcity of useful software tools exist which aid in the development of user and system requirements. It is proposed that requirements analysis should culminate in a set of documents similar to those that usually accompany a delivered Software product. The design of a software tool, the Document Structure Editor, which facilitates the development of such documentation
