DESCRIPTION
User centred design is now mainstream. It’s widely accepted as the best way to create usable systems. Not everyone follows the ISO standard for UCD (ISO 9241-210 previously known as ISO 13407) but the basic principles seem unarguable. Start by understanding the users and context. Then set measurable objectives and test potential designs against these objectives with typical users. Keep refining the design till it meets the objectives. What could possibly go wrong? In this presentation we discuss a number of real world stumbling blocks which mean that even when the process is followed properly ( and not doing it properly is one of the first stumbling blocks), the results are not always what was wanted. Issues include failing to get management buy-in, testing with the wrong users and fixed project schedules which preclude fixing known problems.

If UCD is so great, why are more systems not perfect?
User centred design is now mainstream. It's widely accepted as the best way to create
usable systems. Not everyone follows the ISO standard for UCD (ISO 9241-210 previously
known as ISO 13407) but the basic principles seem unarguable. Start by understanding the
users and context. Then set measurable objectives and test potential designs against these
objectives with typical users. Keep refining the design till it meets the objectives. What could
possibly go wrong? In this presentation we discuss a number of real world stumbling blocks
which mean that even when the process is followed properly ( and not doing it properly is
one of the first stumbling blocks), the results are not always what was wanted. Issues
include failing to get management buy-in, testing with the wrong users and fixed project
schedules which preclude fixing known problems.

Actually, IT projects have a
long history of failure

Typical reasons for failure
1. The technology didn’t work

“in the FCO’s long history of
ineptly implemented IT
initiatives, Prism is the most
badly-designed, ill-
considered one of the lot”

Standards trivia
• Started as ISO 13407
• “Human centred” to
reflect more stakeholders
• Revision is part 210 of
ISO 9241 series
• Part 210 contains “shalls”
ie can claim conformance

Plan the human-centred design process
• What can go wrong?
– Phased development with no time to
incorporate feedback after initial phases
– Organisational changes exposed
‘accidentally’ during design consultation
• Lessons
– Plan for time to incorporate feedback
– Don’t use IT to force organisational change

Understand and specify the context of use
• What can go wrong?
– Scope and position of new product assumed
by remote teams
• Lesson
– Communicate context of use as early as
possible to as many stakeholders as possible

Specify the user requirements
• What can go wrong?
– Project team “hadn’t decided who would use
system”, planned to install then see “who took
to it best”
• Lesson
– Be absolutely clear about target user
characteristics

Produce design solutions to meet user
requirements
• What can go wrong?
– Too early focus on detail, users reluctant to
criticise what appear to be fully worked designs
• Lesson
– Keep design concepts simple prior to initial
evaluation

“Most government IT
therefore remains trapped in
an outdated model, which
attempts to lock project
requirements up-front and
then proceeds at a glacial
pace. The result is repeated
system-wide failure”

Government, March 2011

Iterate where appropriate
• What can go wrong?
– Not enough time to iterate, made worse by
contractual straightjackets
• Lesson
– Plan better, gain management buy in to
agile/ucd process to minimise risk as part of
organisations IT governance

“Many forms of Government design process have
been tried, and will be tried in this world of sin and
woe. No one pretends that democracy user
centred design is perfect or all-wise. Indeed, it has
been said that democracy user centred design is
the worst form of Government design process
except for all those other forms that have been
tried from time to time."
‘based’ on a speech by Winston Churchill, 1947
