The findings reported are based on a daily data-collection process including 2152 work requests which required 11365 days to complete. This set of empirical data confirms some of the findings of the opinion surveys in terms of the stability of the overall workload distribution in the maintenance area, while the analysis of any subset of data indicates that this overall average hides significant differences. The authors include a discussion on the improved measurement program implemented, and illustrate how insights into the maintenance process are gained through various measurements.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

The implications for those wishing to monitor improvements in their maintenance process are discussed, and it is concluded that measurement of average program lifetime is likely to be a better indicator of maintenance improvements than overall maintenance costs. The author also contrasts data processing and embedded systems and suggests that the latter are likely to obey different rules. Embedded systems are therefore excluded from the conclusions drawn.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

The editor offers new capabilities for the graphical construction and editing of data structures. Once data structures have been built graphically, they can be used for testing programs or fragments of programs. The data editor is integrated into a programming environment where it may be used as a debugging aid for the programmer, and it is closely tied to the run-time system of the environment, allowing it to control the duration of execution in a way similar to setting breakpoints. The history of all variables is kept, so the user can retrace the steps by which a variable reached its current state.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

The basic concept of these tools is that integration is made through a model of the underlying software, implemented using an object-oriented technology. Experiences related to the use of these tools are described.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

Validity criteria are defined mathematically. The approach is based on validating selected metrics against related quality factors during development and using the validated metrics during maintenance to: establish initial quality objectives and quality control criteria and prioritize software components (e.g., module) and allocate resources to maintain them. The author illustrates both a case of passing a validation test (discriminative power) and failing a validation test (tracking).<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

The approach to code-to-code (horizontal) transformation is based on a high-level understanding of the programming and application domain concepts represented by the code. A very unique characteristic of this approach is its use of concept recognition, the understanding and abstraction of high-level programming and application domain entities in programs, as the basis for transformations. A program transformation tool has been developed to support the migration of a large manufacturing control system written in COBOL.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.

The DBSD paradigm models the process of software development and maintenance as a continuous problem-solving activity where the decision is the focal point. An important aspect of this process is the preparation for perfective and corrective maintenance by identifying conditional decisions whose validation depends on experience with the production system. Validation requires the instrumentation of the production system to collect data which will support or refute the decision. The authors discuss the instrumenting of a prototype DBSD support environment to collect data to validate the proposed process model. Also given are the results of some preliminary data.<<ETX>>","PeriodicalId":269572,"journal":{"name":"Proceedings.
