    Mascot is the MOD preferred software design method for embedded software systems. It has been widely used, both with and without toolsets, for the design of software written in Pascal and CORAL 66. A report of a study funded by RSRE proposed how to implement Mascot 3 systems using Ada. The paper builds on that study to propose a mapping to allow Mascot 3 to be used with Occam. The proposed method is easy to use without a toolset and appears to produce efficient Occam programs View full abstract»

    The Information Utility was a large research and development project in a medium-sized company. The project encompassed a number of very challenging problems central to the information industry, e.g. libraries. In this project, in this environment, the technical challenges were overshadowed by the philosophical changes required within the company itself. The question of when or whether to move out of a proprietary hardware product environment was central to many of the problems and is faced by other small or medium-sized companies with similar approaches. The paper examines the technical challenges faced by the project in light of this environment. Although this is an example from a single project, similar problems arise in many different projects and companies View full abstract»

    Syntax-based editors typically provide rudimentary operations for manipulating abstract syntax trees. The incorporation of higher level manipulation facilities into such editors can make editing both easier and less error-prone. The authors have implemented a prototype editor that adds useful higher level manipulation facilities, including mid-level semantics-altering manipulations and high-level semantics-preserving transformations. They describe the basic organisation of these manipulations into a manageable number of overloaded commands and show how the commands can be combined in useful editing scripts View full abstract»

    Desired improvement in the software process and product has given rise to greater use of quantitative management techniques in software development. The use of algorithmic-based software cost estimation tools has been a part of this movement. The paper uses data collected from six commercial organisations on 112 software projects to investigate the extent to which organisations need to calibrate these tools to their own environment. It is found that calibration is mandatory if reasonable accuracy is to be obtained from the tools View full abstract»
