But surely he is?
Around 100 years ago there was a prediction that cars would not succeed because
1:-each car needed a mechanic, and 2:-at that current rate of acquisition, by
1950 every young man in america was going to need to be a mechanic. But in
practice thats what happened. Every car became user friendly enough to be home
maintained except for the periodic maintenance from garages.
In a parallel situation now we have solutions being created in spreadsheets,
visual basic. These user domain tools are dumb but are created by intelligent
beings untrained in the computer domain. Given a little more evolution, with a
drop in impedance of information reticulation, storage, and processing, the
same will happen to IT.
> The truth is that we should all work on our system modelling skills
Some of us are pretty good at that and find it increasingly irrelevant. We are
facing price concious buyers who would rather pay a little for something now
than a lot for something latter maybe. Our high end people (e.g. IBM) are
sabotaging our reputations with megabuck screwups (INCIS) based on the old
waterfall model. We are finding increasingly valid hueristics such as the
iterative build processes (the spiral development in preference to the
waterfall model).
The secret to your system modeling skills is a cyclic process of
RAD-deploy-trial, RAD-deploy-trial, in a spiral fashion. System modelling in
the big bang model fails because the user behaviour is changed by the system
that is applied. There is no process that allows system modelling to anticipate
how the user will adapt his work to the new model. Given this, there is no
reason why the dentist cannot mold the product. And the end result will be
exactly right for the dentist, but will be fundamentally different to the model
of the dentistry requirements one would create at the beginning.
