[Year 12 Its] When is programmming started in the SDLC

Thu Apr 27 09:26:49 EST 2006

Hi
I am not sure of what John refers to as "starting the software".
I assume he means after development and testing, which follow the
planning/analysis and design stages. So this occurs during
implementation when the software is introduced and run - with an
appropriate (implementation) changeover strategy.
I used to think that omitting the planning phase was a problem, but at
this level it makes sense to assimilate it into "analysis". SO the
traditional six stages are reduced to: planning/analysis, design,
development, implementation, evaluation/maintenance.
It is the same in both Vic and NSW AFAIK,
hope this helps

Dear All,
These issues just make it more confusing for both us as teachers and our
students. Look at several books on systems analysis and get several
versions of when some things happen in the "SDLC" (...begins retreating
as hisses and boos begin, and fruit is about to be thrown...lucky
water-melons are out of season as Groucho once said....). Oh how I miss
the "old" days of computer science, when we really got into topics such
as how hardware works, programming involving searching,
sorting,linkedlists etc, binary logic and gates, number systems
(...knows this is sounding like a broken record and thus stops this
useless remimiscence..). 
But on a more serious note, thanks for the ideas. The SDLC is here to
stay in the course for the next few years, so the more clarification we
get, the better.

Regards (...this is probably implementation..) Frank
