EDITORIAL
By Monique Cuvelier
If you build it, they may come -- but they'll leave if they can't
figure out how to use it. The difference between a website that's
accessible to everyone and one that's overly complicated can break an
online venture.
Yet it's the fate that befalls too many websites: usability and
accessibility are pushed aside, considered nice to have, but not
essential to have. It's understandable when companies are facing
burning issues such as compliance regulations or meeting financial
goals or making delivery deadlines. But none of that matters a whit if
no one can use the thing you're building.
Just ask Jenny Craven and Mikael Snaprud, who wrote this issue's
feature on their ambitious project to improve web accessibility. They
estimate 10 per cent of the population has some kind of a disability
that can prevent them from fully using a site, which will only
increase as the population ages.
Outside help might be the answer if you need to make your site more
usable, but you want to make sure you hire the right person. Usability
veteran John S. Rhodes offers concrete tips on how to find and work
with the right professional.
Of course, we're not discounting those burning issues, such as
compliance with anti-money-laundering legislation. That's why we asked
Eldin Rammell to review a book we know many of you might be
considering these days: "Making IT Governance Work in a Sarbanes-Oxley
World". We also invited VIP editor Pam Foster to give us a list of the
most useful websites she used when writing her impressive feature on
compliance in the August issue of VIP
(available by the end of the month). Her detailed articles can help
you comply with the myriad financial regulations in force today.
We know working in the information industry is as much about juggling
as it is being an expert in knowledge. We might not be able to handle
everything for you, but in this issue we hope to increase your
dexterity so you can keep all the balls in the air.

MY FAVOURITE TIPPLES
By Pam Foster
As editor of VIP , I've been working to help
our readers better understand compliance issues by researching what
products the major information providers are offering to help
professionals meet anti-money laundering regulations. This month,
we're featuring several articles on the topic, which you can read by
subscribing to VIP, but here are some additional websites I found
useful in my research. I know you'll find them useful too.
* Financial Services Authority (FSA) is the
UK's single financial regulator. The FSA Library is a good starting
point for locating international information on corporate
accountability regulations.
* The Joint Money Laundering Steering Group (JMLSG) website
is a service provided by the British
Bankers' Association on behalf of JMLSG. It contains important
information about countering money laundering.
* The Law Society is the regulatory
and representative body for 116,000 solicitors in England and Wales.
It offers extensive guidance on money laundering.
* Bank for International Settlements (BIS) ,
located in Basel, Switzerland, is an international organisation that
fosters international monetary and financial co-operation. It
provides information on central banks as well as details of the
Basel II regulatory capital framework.
* It's always handy to be able to refer to a glossary when dealing
with financial matters, as the terminology can be complex. My
favourite is Yahoo's .

Financial footing can be slippery in the library business, and
FreePint Bar members are talking about how to cash in, from library
income boosters to paying for university. Anti-money-laundering
legislation is keeping everyone honest, but compliance is a challenge.
Belly up to the Bar to read these topics and more.
* Libraries are not known as big money-makers, and one person is
wondering how they earn income. Those serious about bringing in cash
have business plans, which may sketch out anything from cafes to
low-cost printing services. Other ideas on how to boost revenue?
Chime in .
* Finances can be equally hard to find for an education in library and
information studies. As one Student Bar member wonders how to pay
for college, some professionals are suggesting special bank loans,
or guidance from the Grants Register and the Directory of Grant-
Making Trusts. Read more helpful advice or lend your own
.
* Everyone knows what a struggle complying with anti-money-laundering
legislation can be; we want to know more in the VIP Lounge. Just how
is your information department coping
? Have you stumbled on any
unforeseen benefits ?
* Do mail servers ever lie? That may sound like the title to a Philip
K. Dick novel, but it's a compelling question one FreePint Bar
member is asking. When emailing press releases, he wonders if any
of the bounced-back messages are fudged by mail servers. Contribute
to this informative discussion .

TIPS ARTICLE
"Working with a Usability Specialist"
By John S. Rhodes
Most companies are focused on everything but people. I'm certain
you've seen the same thing. The focus is on profits, engineering,
marketing, operations and so forth. Customers are left in the dust.
This is alarming because business is a human endeavour. To succeed in
business you must understand people. You must cater to their needs.
You must bend technology, processes and policies around your customers
-- not the other way around.
This simply means that products should be built around humans. For
example, it is easier to sew together some leather to craft a glove
than it is reshape the human hand, don't you agree?
In light of this, being concerned with usability is a business
imperative. If you sell products, if you have customers or if you are
worried about your competition, usability is a concern. The reason is
simple: usability helps your organisation stay focused on customers in
exactly the right way.
Usability isn't a bag of opinions. It is rigorous, systematic and
scientific. Furthermore, a tidal wave of research has very clearly
shown that the return on investment in usability is outstanding. For
example, Martin and McClure (1993) as well as Pressman (1992) have
demonstrated that 80 per cent of software maintenance is due to unmet
or unforeseen user requirements; only 20 per cent is due to bugs or
reliability problems.
A usability specialist can help you via user interviews, focus groups,
cognitive task analyses, usability reviews, usability testing, and
much more. The challenges you face will determine which tools and
research will be applied.
The bottom line is that if you aren't focused on your customers in the
right way, you won't succeed in the long run. You cannot simply think
about customers and expect success, however. You can't make wishes and
expect miracles. You have to recognise the issues and attack them in
the right way with the resources and tools. You need usability.
Seven signs you need a usability specialist
-------------------------------------------
How do you recognise if you need usability help? You're probably
already familiar with some of the red flags that tell you so.
First, you know you need help if you launch a product or service and
the quality is low. If you push something out the door and there are
issues it often means that you didn't focus on your customers. As I
stated in an article titled Business Case for Usability
, according to
Lederer and Prassad (1992), 63 per cent of all software projects
overrun their budgetary estimates, with the top four reasons all
related to unforeseen usability problems. Similarly, usability
engineering has demonstrated reductions in the product-development
cycle by over 33-50 per cent (Bosert 1991). Are you facing quality
issues that are really usability issues?
Second, you need usability help if your help desk and service calls
are going through the roof. Emails and phone calls are generated by
people. If these people are satisfied, then they won't jam up your
call centre. However, if they are unhappy, you can expect a deluge of
incoming complaints. Here's a caveat: I'll boldly state that I've seen
low-quality products become insanely successful because the needs of
customers were met in the right way. Customer satisfaction can trump
quality, but it's rare.
Third, when your internal and external training costs are high, it
means you need some usability injected into your products and
services. Training is often the paint that covers the cracks in the
walls of your products. Problems are pushed to the future. The
assumption is that training will solve product problems but the truth
is your products should be built around users in the first place. You
can drive down training time if your product is simple and easy to
use.
Fourth, if you are having problems attracting new customers, it is
time to bring in a usability specialist. You can seriously jack up the
probability of success by learning more about what makes customers
tick. Armed with this knowledge, you can reshape your product to
reflect customer expectations. This drives down design and development
costs and it gets you to market faster too.
Fifth, when marketing, engineering and operations aren't
communicating, it is time for more usability. I've seen the smartest
people in the smartest companies talk right past each other. The
jargon flows to the detriment of customers. Usability can force your
organisation to talk using the language of your customers. This is a
good thing, no doubt. When your company revolves around customers,
everyone used the same words to describe the issues and challenges.
This alignment of language and concepts is what you want because it
drives efficiency and quality.
Sixth, if your organisation is unable to generate ideas, usability is
the answer. When creativity is in the dumps, working with users in the
right way will drive innovation. Your marketing team can learn to
think in terms of customers and solutions versus markets, promotions
and advertising. The executive team can see how their strategy can
evolve or radically shift to accommodate the needs of the people that
are spending money.
Finally, when your products reach a point of ridiculous feature bloat
and complexity, you know it is time to get some usability help. Many
companies recognise that their products are too complicated, but they
feel paralysed. They cannot act. Usability can help you sift through
the rock pile to find the gems that your customers care about. This is
good for customers and it is good for your bottom line.
Four ways to find the right usability specialist
------------------------------------------------
If you're convinced that you need usability help, then consider what
it will take to hire the right usability specialist. The tips here are
meant to guide you in the right direction.
First, you should ask basic questions about past experience. Look for
a background that relates to your business. However, keep in mind that
most usability specialists use many tools and techniques. The key is
to feel comfortable that the usability specialist understands your
business needs. My advice is to work with a usability specialist that
can understand not only your customers but also your business.
Second, treat the usability specialist like a partner or high-value
employee. Finding the right usability specialist is like headhunting
for an executive. I suggest that you treat early interactions like job
interviews. Maximising the time you invest in searching for the right
one will help you find the right fit.
Third, in addition to asking for references and a list of services,
consider asking for case studies, samples or quick proof. Furthermore,
look for a person who is on top of their game right now. For example,
many people know that I keep up to date with usability because they
know about WebWord.com, which is where I regularly update my blog.
Blogs and authorship can be a useful way for you to check out the
reputation of the usability specialist.
Finally, consider building usability inside your company with
usability training. Inject usability into your company to head off
problems before they happen instead of trying to buy it to fix a few
issues. If you're looking for high value, teach your designers and
developers these skills. Many usability specialists are good trainers,
so ask about this option to maximise your investment.
These tips will help you quickly weed out people that don't fit with
your company. You want the right usability professional on board if
you want to make the magic happen.
How to obtain maximum benefit from a usability specialist
---------------------------------------------------------
I strongly advocate that you should first review your business goals
before you obtain the help of a usability specialist. If you have
basic manufacturing issues, for example, consider fixing those first.
You might be surprised to learn that the return on that investment is
much higher than usability. Take care of your fundamental business
first and be very aware of what you really need.
Once you have identified your business objectives, think about what
kind of help you need. Are you looking for tactical help or strategic
vision? Are you looking for a short-term fix or a long-term training
program? The better you understand your objectives and your pain
points, the better a usability professional will serve your company.
The higher-quality usability specialists will ask excellent questions
about your business when you talk to them. They will dig into issues
and look for the problems that need answers. If solutions start flying
before you've had the opportunity to explore the problem space, then
be sure to run like the wind. You want to be sure that the usability
specialist has a firm understanding of the landscape. Solutions will
follow.
To generate serious value and avoid fallout, consider the output and
impact of the usability work completed. Simply stated, the work
completed will force changes in your organisation. Prepare everyone
for the changes that are coming. Let people know that they will need
to accept some risk to make products and services better for
customers. Work the appropriate change management channels. I've
worked as a usability consultant as well as a business analyst,
software engineer and project manager. Trust me; changes are part of
the game, so plan accordingly. If you expect any culture change,
prepare now to secure the greatest return on investment.
Earlier I wrote about usability consulting versus usability training.
Even if you opt out of training, be sure to have your usability
specialist spend some time on knowledge transfer. Bake that into the
proposal and the project. Keep in mind that usability folks have broad
knowledge and expertise, at many levels. This means that you can
probably extract a lot of value. Also, I know from personal
experience, that it is a good idea to load your budget with this in
mind. Be fair.
If you are working with a usability professional to explain or sell
usability to others in your organisation, consider using analogies and
case studies. Recently, I was working with a potential client about
his internal sales efforts. It was very useful to explain the
usability maturity model in light of the Capability Maturity Model
(CMMI) and Six Sigma. He used this information to properly place
usability in reference to known executive models.
Sometimes usability is a tricky animal. Getting exactly what you want
can take some time. In other cases you just need the magic usability
dust sprinkled on the project. I'm being a bit facetious, but your
needs will wax and wane over time. Therefore, you should consider a
retainer. The better usability specialists appreciate such
partnerships. They tend to have vision and they continuously seek to
drive returns for companies and users alike.
I'll end by reiterating a comment made earlier. Definitely make sure
that you have the usability specialist interact with many different
people in your organisation. Usability isn't a singular activity with
a singular purpose. It is multifaceted. Make certain that the
usability professional spends some time with your marketing team,
product develop group, operations division, designs, developers and
executives.

REVIEW
"Making IT Governance Work in a Sarbanes-Oxley World"
Written by J. Bloem, M. van Doorm, P. Mittal
Reviewed by Eldin Rammell
"Making IT Governance Work in a Sarbanes-Oxley World", by J. Bloem, M.
van Doorm and P. Mittal, contains a wealth of information about
governance of information technology in large corporations. If you are
new to this topic and want a detailed discussion of the intricacies of
IT governance, then this book may be for you. You will read an
introduction to most of the commonly accepted frameworks for
governance from KIMBIA to CoBIT to the managed scorecard. You will
also read a brief overview of the Public Company Accounting Reform and
Investor Protection Act of 2002 (Sarbanes-Oxley). Despite the title,
it doesn't touch much on the intricacies of Sarbanes-Oxley, but is
primarily a discussion of IT governance. In this, it goes into great
detail.
The preface to the book is excellent. It's a 22-page summary that will
provide an insight into what constitutes good IT governance and the
impact that Sarbanes-Oxley is making on corporations. In the preface,
the authors introduce a theme that continues throughout the book: the
role and importance that behaviour has on IT governance. This is
particularly important post-Sarbanes-Oxley where a CFO and CEO can no
longer rely on just 'trusting' financial accounts presented to them.
Developing the right employee behaviours has a major influence on
leadership and accountability within an organisation and thereby, on
compliance with governance structures in the corporation.
The book is not light reading, however. It is well arranged in three
inter-related sections: management, accountability and supervision.
Within each section, the flow of topics is logical, but they're not
well connected.
This book will also appeal more to a US audience. Some sections ('IT
pushes production up but Europe lags far behind' and 'Europe does not
have its statistical house in order', in particular) may even make
European readers bristle.
Despite its detractions, "Making IT Governance Work" is still useful.
Chapter 3, for example, includes a sound overview of some basic
management principles. I like the three critical success factors for
IT managers: (1) create the conditions in which IT managers can create
value; (2) IT managers have to prove themselves; and (3) IT managers
must deliver. Get these right and you are well on your way to
successful IT governance. Chapter 7 includes a very useful description
of leadership models, particularly in their relation to overseeing and
managing change, an essential component of IT governance in today's
world.
In a nutshell, this is a book with a great amount of valuable content,
but its style detracts from its readability. Read the preface from
start to finish and then dip into the rest from time to time when you
have a spare 10 minutes. It's a good book for the reference shelf, if
not something you'll read cover to cover.

By Jenny Craven and Mikael Snaprud
Sometimes, simply launching a website can take a huge amount of time
and effort, never mind making sure it is consistent with every type of
web browser and compatible with different types of add-on
technologies. However, making websites accessible is an issue that
anyone with responsibilities for web development and web-related
policy-making should be concerned about.
For one reason, it's estimated that 10 per cent of the population has
some kind of a disability -- a number likely to grow as the population
ages. Web content isn't always accessible to these people as they may
rely on add-on or assistive technologies to access the web, such as
screen readers, magnification, voice recognition and alternative mouse
devices.
Web accessibility matters to far more than 10 per cent of the
population, however. It also affects anyone working with voice
browsers, mobile phones, handheld devices or in a hands-free
environment. Websites should be for everyone, because if they aren't,
organisations cannot reach their communication goals, and individuals
can be left behind. The web is how we share information, and you want
to be able to share with everyone visiting your site, no matter how
they access or interact with it.
Clearly, not everyone is sharing. A study of the accessibility of
museum, library and archive websites in the UK revealed that 'less
than half the sites audited met the most basic Web Accessibility
Initiative technical accessibility guidelines' [1]. Another study,
conducted by the UK Disability Rights Commission, found that of 1,000
websites, 81 per cent failed to reach the minimum Web Content
Accessibility Guidelines standards [2]. Findings from the UK Cabinet
Office assessment of government websites across Europe found
'relatively few sites that achieve even Limited Pass Level A
conformance with the W3C Web Content Accessibility Guidelines (WCAG
1.0)' [3].
Some websites are meeting those guidelines. Examples of good design,
particularly for blind and visually impaired people, are provided by
the Visionary Design Awards. This campaign to encourage people to make
their websites more accessible is run each year by the National
Library for the Blind in the UK . Winners from
2005-6 include Ocado , RNID
and Stable Close Equine Practice
.
As part of the European Commission IST programme of research to
support electronic inclusion, accessible web design, development and
assessment has been the focus of a Web Accessibility Benchmarking
(WAB) cluster of three EU-funded projects. These projects are working
to develop a harmonised European methodology for website evaluation
and benchmarking, called the Unified Web Accessibility Methodology or
UWEM . The cluster projects are The
European Internet Accessibility Observatory (EIAO)
, SupportEAM
and BenToWeb
.
This article will focus on the work of the European Internet
Accessibility Observatory (EIAO).
The European Internet Accessibility Observatory
-----------------------------------------------
The European Internet Accessibility Observatory (EIAO) aims to make
sites such as these the standard, rather than the exception. This
project, launched September 2004, strives to provide policy makers
with a tool to observe and improve the effect of accessibility. Web
designers, editors and commissioners will have a basis for policy
making, research and actions to improve accessibility to web-based
content.
The Observatory will consist of the following elements:
* An Internet crawler for automatic and frequent collection of data on
web accessibility and deviations from web standards
* A set of Web Accessibility Metrics based on the Web Content
Accessibility Guidelines (WCAG) published by the Web Accessibility
Initiative
* A data warehouse to provide online access to collected data.
The EIAO project is a direct result of a European Commission
initiative. Since 2002, the Commission has been working on an action
plan to achieve 'an "Information Society for All", promoting an
inclusive digital society that provides opportunities for all and
minimises the risk of exclusion' [4]. The measures recommended by the
commission include Design for All methods, and evaluation and
monitoring of the accessibility of websites. These methods are based
on the World Wide Web Consortium's Web Accessibility Initiative (WAI)
, which include the Web Content Accessibility
Guidelines version 1.0, with a view to move to version 2.0. WCAG 1.0
recommendations include providing alternative text for images and
graphics, meaningful descriptions for all hypertext links, logical
page organisation including correct use of headings and lists, and
providing titles and summaries for frames and tables.
The EIAO project is the first project we are aware of that
demonstrates how large-scale benchmarking can be implemented using an
open-source architecture supporting the integration of third-party
evaluation tools (see Ulltveit-Moe, Gjosaeter, and Snaprud (2005) [5],
and Snaprud, Balachandran, and Goodwin Olsen [6], for more information
on the software architecture). The measurements are fully transparent
to allow review and encourage improvement. The selected license also
facilitates research collaboration with other open-source developers
and encourages others to use the software for measurements, teaching,
research or any other purpose.
The Observatory assesses a sample of pages from a website and presents
the barriers it finds, such as missing alternative text for images or
inconsistent page organisation (currently based on WCAG 0.1). Many
existing web-accessibility evaluation tools can evaluate one web page
and indicate detected barriers for that page. In contrast, the
Observatory will present data representing an entire website or a
group of websites. An evaluation of one website currently includes 75
tests on 100-200 web pages.
Results, available online, may be a brief report on the accessibility
of a particular feature or a full-blown report on the position of a
website's accessibility in relation to a sector, region or country.
The final version of the prototype Observatory will publish monthly
updated measurements from around 10,000 websites.
Preliminary results
-------------------
Results obtained from the first evaluation of five European Prime
Minister's websites (ministries in Germany, Norway, Spain, the
Netherlands and France), demonstrated the functionality of the
Observatory and illustrated the character of its data.
They revealed information about the most-frequently encountered
barriers and targeted potential regional differences. Aggregated
results showed between 990 and 3,098 barriers per page. To some extent
the number of barriers per page can be a result of a difference in
design. For instance, one site's pages may have much more content, and
thus barriers, than another.
The most frequent violation was the use of obsolete commands, known as
deprecated features. For example, using an HTML tag rather than
the 'font' element in cascading style sheets.
Lack of style sheets used to control layout and presentation was the
second most frequent problem, as defined by the WCAG guidelines.
Appropriate use of style sheets will allow users to adjust the
appearance of a webpage according to his or her needs, for example, to
change the font size or background colour.
Large blocks of text were the third most frequently detected deviation
from the guidelines. Dividing larger blocks of text into paragraphs
and organising the structure with headers improves accessibility for
all users.
Other examples of barriers include pop-ups, missing text-equivalents
for non-text elements, such as a text description for a picture, and
improper identification of the primary natural language. Failing to
comply with this can cause a speech synthesiser to pronounce the text
in unintelligible ways, for instance by using an American accent with
Norwegian text.
Together, these barriers may render a site impossible to navigate for
a user who is visually impaired or working on a scaled-down device
such as a phone.
A user-centric approach to improve the observatory
--------------------------------------------------
The project has adopted a user-centric approach to development because
it recognises the limitations and concerns surrounding automated
testing. The tools for automated data collection and dissemination
will be developed and continuously improved throughout the project by
feedback from users and user testing.
Involving users in the process has provided many benefits. For
example, it has been possible to identify the main accessibility
barriers experienced by disabled user groups and then to feed this
information into the selection and development of the Web
Accessibility Metrics. It has also enabled comparisons from user
testing and automated testing.
Initially the difference between user and automated results was wide,
prompting further development and enhancement of the aggregation
methods. Now automated and user testing is more aligned, and more
tests and evaluation will continue to improve the Observatory.
This has been an important exercise for the project team, who are keen
to address the concerns of stakeholder groups relating to the
reliability of automated testing. The team also recognises the fact
that the user experience of accessibility does not always match an
automated approach. Issues such as these will be addressed through
ongoing development, dissemination, promotion and evaluation.
The future of accessibility
---------------------------
Ensuring access is widened to as many people as possible should be a
high priority for anyone involved in the delivery of web-based
resources, whether it be a web designer, web manager, commissioner or
policy maker. Evidence has shown that there is a growing awareness
among such people of the importance of accessibility (see for example
ENABLED: Analysis of the ENABLED web developer survey
, 'Involving Users in the Development of a
Web Accessibility Tool'
, SupportEAM
and the recent Minister conference on
e-Inclusion in Riga ).
The extensive EU programme of projects and activities that fall under
the IST e-inclusion programme is helping to improve web accessibility.
But, even with these projects, and initiatives such as the Lisbon
Strategy (now i2010), the e-accessibility action and the World Wide
Web Consortium, web developers often still need practical advice on
how best to implement, assess, monitor and maintain accessible
website.
The EIAO project is planning to extend beyond the period funded by the
European Commission. This may include synergies with e-government
benchmarking and training to improve the benchmarked web sites and to
increase general awareness.
How you can help
----------------
The EIAO project will soon allow online access to the data warehouse
via a user interface. As part of the on-going user focus, the project
team will be inviting anyone who
has web responsibilities (web design, development, commissioning,
policy development) to try out the EIAO user interface and to complete
a short online evaluation form, which will enable improvements for the
next release version. Keep checking the EIAO website for details and
the work of the WAB Cluster.
Resources
---------
Currently, there are a number of valuable resources that will help
people create and maintain better and more accessible web sites. These
include:
* W3C-WAI Guidelines . These
guidelines are a set of rules for developers that ensure a website
or application is accessible to as many people as possible. They
include guidance for accessible web content, user agents, and web-
authoring tools.
* PAS 78 (British Standards Institute, 2006)
. These recently
published guidelines from the British Standards Institution (BSI)
provide guidance on how to design websites that are usable and
accessible to disabled people.
* The Accessibility Foundation . The
Netherlands based Bartimeus Accessibility Foundation provides
information, consultancy and training on web-accessibility related.
The site is also available in English.
* The Royal National Institute of the Blind Web access centre
provides information for web designers,
developers, content authors and website managers on how to how to
plan, build and test accessible websites.
* "Building Accessible Websites"
is the electronic
version of a book that explains how and why to make sites
accessible.
* "Adaptive Technology for the Internet: Making Electronic Resources
Accessible to All" is an online book from
the American Library Association that shows how to establish
accessible websites and acquire the hardware and software needed by
people with disabilities.
