This document discusses several ISO standards related to usability and human-centered design. It outlines standards that define what usability information should be documented, how to conduct and report on usability tests, and how to implement user-centered design processes. The document recommends some key ISO standards, including ISO 9241-11 which defines usability, ISO 9241-210 which provides guidelines for human-centered design processes, and ISO/IEC 15288 which integrates user-centered design into systems engineering. It encourages contributions to ISO standards to help improve processes for user experience and accessibility.

What ISO standards can do for you, and you can do for ISO
Nigel Bevan, Professional Usability Services
Documenting information about usability
ISO/IEC
25063
explains
what
information
about
the
context
of
use
should
be
identified
and
documented
at
different
stages
of
design
and
development.
ISO/IEC
25064
explains
what
should
be
contained
in
a
user
needs
report.
ISO/IEC
DIS
25065
defines
the
content
of
usability
evaluation
reports.
Usability and human-centred quality
ISO
9241-­‐11
defines
usability
as:
The
extent
to
which
a
product
can
be
used
by
specified
users
to
achieve
specified
goals
with
effectiveness,
efficiency
and
satisfaction
in
a
specified
context
of
use.
ISO
CD
9241-­‐220
defines
human
centred
quality
as:
Usability,
accessibility,
UX,
and
risk
reduction.
ISO
20282-­‐2
provides
a
rigorous
usability
test
method.
ISO/IEC
25062
provides
a
means
to
document
summative
usability
test
results.
Helping your organisation improve its
process
ISO
TR
18529
provide
the
most
comprehensive
and
authoritative
definition
of
the
activities
needed
to
implement
user
centred
design,
derived
from
a
wide
range
of
sources
including
surveys
of
best
practice
in
industry.
It
can
be
used
as
the
basis
for
assessing
whether
a
project
has
adequately
implemented
human
centred
design,
or
for
assessing
the
usability
maturity
of
an
organization.
Good practice in user centred design
The
ISO
9241-­‐210
standard
for
human-­‐centered
design
processes
for
interactive
systems
is
intended
as
a
manager’s
guide,
and
is
probably
the
best
concise
introduction
to
usability
that
is
available.
Better user interface design
The
collections
of
guidelines
in
ISO
standards
provide
a
very
good
primer
for
good
practice
in
user
interface
design.
They
can
also
provide
authoritative
evidence
to
cite
if
a
user
interface
design
decision
is
challenged.

Making usability a part of systems
engineering
Usability
has
been
broadened
into
the
concept
quality
in
use
in
software
quality
standards:
a
high
level
objective
to
design
a
product
so
that
it
is
effective,
efficient,
satisfying
and
risk-­‐free
for
its
users.
The
basics
of
the
user
centred
design
process
have
been
integrated
into
the
ISO
systems
engineering
standard
ISO/IEC
15288.
