in the sprint planning that has to happen. For example, Jean-Luc would let
me know we really needed to have a
certain aspect of the UI sorted out by
some particular sprint, which meant
I had essentially received my marching orders. Conversely, there also were
times when I needed to see some particular functionality in place in time to
use it as part of a live build I wanted to
incorporate into an upcoming round
of formative testing. That, alone, would
require a ton of coordination.
The other important influence on
sprint planning comes from product
management, since they too often
want to be able to show off some certain capabilities by some particular
date. With all three of these vested in-

terests constantly vying to have certain
parts of the product materialize by certain points in time, there’s plenty of negotiating to be done along the way.
RutteR: Yes, but I think you have
to accept that some reengineering of
bits and pieces along the way is just an
inherent part of the process. That is,
based on feedback from testing, you
can bank on sprints down the line involving the reengineering of at least a
few of the things that have already been
built. But as long as that’s what you ex-pect…no problem.
aGathos: I think you’re right about
that: we have to develop a mind-set
that’s accepting of changes along the
way. But I actually think the biggest
problem is the tooling. The develop-

ment tools we have today don’t help
us with all those iterations because
they don’t provide enough separation
between the business logic and the UI.
Ideally, we should be able to change
the UI from top to bottom and revisit
absolutely every last bit of it without
ever touching the underlying logic.
Unfortunately, today that just isn’t the
case.
GosPeR: That’s why, as a UX interaction designer, you have to be prepared
to demonstrate to the product developers that any changes you’re recommending are based on substantive
evidence, not just some intuitive or
anecdotal sense of the users’ needs.
You need to make a strong case and be
able to support design changes with as
