10. When one technology is
displaced by another
technology, the pattern might
look something like this:
16. The graph below suggests that
mobile phone cameras are
increasingly used instead of
DSLR cameras…
17. And perhaps even more
evidently, mobile phone
cameras are displacing
compact cameras.
18. The Technology S-curve would
predict that a technology is
more likely to be displaced
when it has reached the limits
of what is scientifically possible.
19. But compact cameras have not
reached this limit – in fact they
are becoming better and better
all the time.

Yet still they’re being replaced…
21. This simple example illustrates
one of the greatest problems
with the Technology S-curve:

one of the greatest problems
with the Technology S-curve:
it doesn’t take the market into
consideration.
23. Another problem:
It is one-dimensional, but
technologies need to be
compared across several
dimensions.
24. Let’s try to map compact
cameras and mobile phones in a
different way!

any additional customer value.
Who needs another megapixel when you
have 10 already?

mobile and compact cameras.

products then improves over

Mobile cameras still offer worse image quality, but
it is good enough. Also, they are easier to bring
along. At this point, compact cameras will be
replaced, this started to happen in 2005-2006… Portability
46. The phenomenon is called
’Technology overshooting’, and
refers to when technologies
have not reached their peak of
the S-curve, but are still
replaced because customers do
not value additional
performance.
