Questionnaire resources
It has been observed that questionnaires are the most frequently
used tools for usability evaluation. This page is a list of usability
questionnaire resources, extending the information presented on
the questionnaires page of Usabilitynet.
 SUMI
This is a mature questionnaire whose standardisation base and manual
have been regularly updated. It is good for desktop products, but has
also been used to evaluate command-and-control applications. It is a commercial
product which comes complete with scoring and report generation software.
It is designed and sold by the Human Factors Research Group at University
College Cork.
WAMMI
This is a new questionnaire, designed to evaluate the quality of use
of web sites. It is backed up by an extensive standardisation database,
and it is purchased on a per report basis. It is the result of a joint
development project by Jurek Kirakowski and Nigel Claridge.
SUS
This is a mature questionnaire, developed by John
Brooke in 1986 and
not
published until years later. It is very robust and has been extensively
used and adapted. It is public domain and nobody has published any standardisation
data about it. Of all the public domain questionnaires, this is the most
strongly recommended.
QUIS
This is a questionnaire developed by Kent Norman that has been modified
many times to keep it current since its first appearance. It is commercially
available and is championed by Ben Shneiderman in his book Designing the
User Interface. Reading, MA: Addison-Wesley Publishing Co., 1998. Despite
lack of standardisation and validation data, it has many adherents.
USE (see http://www.mindspring.com/~alund/USE/IntroductionToUse.html)
This questionnaire is still in development by Arnie Lund (last updated
11/11/98). It attempts to create a three-factor model of usability that
can be applied to many situations. However, no reliability or validation
data are presented. Public domain use is encouraged.
CSUQ
This is a well-designed questionnaire developed by Jim Lewis and it is
public domain. It has excellent psychometric reliability properties but
no standardisation base.
IsoNorm
(in German only)
This questionnaire is designed to test the usability quality of software
following the ISO 9241 part 10 principles. It is created by a team led
by Jochim Puemper. Strong reliabilities are claimed for the sub-scales,
although it appears there may be a strong inter-correlation between them
as well. Downloads and an on-line version are available from the above
URL, as well as articles about it (all in German.)
IsoMetrics
This questionnaire is produced by Guenter Gediga and his team. It is
another attempt to produce a way of measuring ISO 9241 part 10, with reference
to specific software features that may give rise to low usability data.
It is therefore good both for summative and formative assessments. The
questionnaire is well researched and detailed statistical information
is given. Downloads of English and German versions are available. There
is no standardisation base for it but it is public domain.
