Agreed. However I would add that much of those
phases are about perception. It has *always* taken
an understanding of all three elements to make even
a fairly simple search-and-transaction web site
successful. From the perspective of building ecommerce
web sites, this has been the sequence in client perceptions:
1. Clients were mad about cool HTML and flashy
interfaces, and it was extremely difficult to make
them see reason. However, they were blind to data
exchange and knowledge handling, so I was able
to build those parts of web sites in relative peace
and quiet.
2. Now clients are gradually accepting that an
interface has to be usable, and are slowly and
reluctantly giving up the cool HTML. However,
they have discovered data exchange -- or more
properly they have read about XML -- and are
now focusing their interest on that. As HTML
was at first, it's a tools-before-architecture
mentality. Ready-fire-aim.
3. Semantics is still beyond their radar screen.
Right now people's minds go numb when they
hear "knowledge management." However, once
the clients realize there are actual knowledge
management tools in the offing, they will want
some of those.
