Communicating GUI Requirements for Medical Device Software Takes Words and Pictures, Intertech's Dave Vogel Writes
| Source: Intertech
NORWOOD, MA -- (MARKET WIRE) -- October 25, 2006 -- Now that medical device software looks more
like personal computer software, communicating graphical user interface
requirements has become more challenging because of the need for documented
requirements and traceability to designs and verification tests, David
Vogel, president of Intertech Engineering Associates, writes in the Oct. 20
issue of Mass High Tech.
"Understanding the problems and giving some forethought about how to deal
with GUI requirements will result in shorter requirements and development
schedules.....and result in more robust software that meets user and market
needs," he writes.
And communicating GUI requirements successfully takes both pictures and
words -- and it's the latter that developers often skimp on.
"Developers need words to explicitly describe what is important enough
about the picture to become requirements. Testers need to know this too so
that their verification tests are neither too superficial nor filled with
minutia," Vogel asserts.
For best results, pictures and text medium must stay synchronized. That
takes more work, but it's more than offset by overall savings in time and
more effective development.
