Because the average programmer makes 1 mistake in every 7-10 lines of
sourcecode, building reliable, large-scale systems poses a challenge for
institutions that have specific needs. The maintenance of such systems in a
cost-effective manner is challenging as maintenance represents 90% of software
development costs, often far more than institutions anticipate. Forward
Engineering is the process of automatically generating software from design
specifications. Using forward-engineering techniques, software designers can
design large software systems, and much of the software can be automatically
generated, following established standards both technically, and also
process-standards established within the industry / organization. Such
techniques are attractive because (a) they streamline the prototyping process,
(b) they allow for the software to evolve at the design level, and (c) they
guarantee that standards / best practices are enforced as they evolve. Many
developments in requirements analysis have allowed specification theory to
elevate the comprehensiveness of software designs, such as the Zachman
Framework. As purchasers, it is important to understand this thoroughly so that
the expensive systems function properly in our organizations. One of us (BR)
has built a forward-engineering engine. That engine subsequently built twelve
different medical software products, based on recent developments in
requirements analysis. This engine has produced twelve products, online in
fifteen different hospitals, spanning five different languages, with 92% of the
source code generated automatically from the design configurations. The
implications of forward engineering to radiology software contracting will be
discussed, along with the implications of requirements analysis to software
purchasing.
1. Understand the concept of forward engineering 2. Assess the difference
between forward engineered and traditionally coded software. 3. Understand the
significance of forward engineered software to the costs and contractual issues
related to software purchases 4. Understand the implication of requirements
analysis in radiology software purchasing. (B.R. is a principle of
MyBestHealth.)
