An Investigation Into The Causes And Effects Of Legacy Status In A System With A View To Assessing Both Systems Currently In Use And Those Being Considered For Introduction, Patricia O'Byrne
Other resources
This dissertation analyses the area of legacy systems and determines the effects that are exhibited in legacy systems, presenting them in a legacy effect determination framework, so that management can ascertain whether the system they have is a legacy system. An analysis of legacy causal criteria is carried out, resulting in a table of legacy causes. A new definition of legacy systems is put forward, by defining legacy status as a status held by a legacy system. “A system exhibits legacy status if it is deficient in terms of its suitability to the business, its platform suitability or application software …

There has been a paradigm shift in medical informatics standards in recent years from the message-oriented approach to a more distributed systems approach. However, despite all the early promise of distributed applications, they haven't been widely adopted in the health domain for various reasons. As a result, despite an increasing need for a standardised distributed solution for analytical laboratory instruments, many implementers of instrument interfaces are still using proprietary serial interfaces which do not support distribution. The emergence of the eXtended Markup Language (XML) specification in 1998 revived the fortunes of the messaged oriented methodology. This paper presents a partial …

A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix
Conference papers
Recent international quality standards and European Community legislation have identified new software quality factors. These new factors include suitability, installability and adaptability. Other quality factors need to be reviewed in the light of these developments. This has impacted on established commercial usability evaluation methods to the extent that it is appropriate to ask if these evaluation methods comply with the new standards and legislation. In order to answer this question the commercial evaluation methods need to be appraised (meta-evaluation) using a suitable method appraisal process. This paper describes such an appraisal process which specifically addresses the many considerations raised by …
