4Oracle UI Examples
- Simple examples become very complex problem when
done on a global scale - How to represent all the worlds tax laws in a
single UI ? - How to describe every address on earth in a
single UI ? - Examples
- Tax Definition calculating, billing, collecting
and reporting taxes on products your company
builds or sells - Customer Information a data model for creating
and maintaining customer information - These two interact and require exact data for
legal reasons - End user is everyone
- Administrative user is business not technical
specialist - Setup and configuration errors are fatal
5InvoiceSample
6Etax Setup Legal Boundaries
Where is company?
Where is inventory?
7Etax Setup Tax Definition
Whose law is in effect for any given transaction?
8Etax Setup Effective Dates
How long is the law valid for?
9InvoiceSample
10TCA Mixed Global Addresses
Many countries, different formats
11Create an Address
Standard US address format
12In Another Country
But company is in Japan
13Structured Data is Different
Same database but different format of structured
data.
14Some Lessons Learned
- Requirements gathering need to know more than
just who the user is. - Rules laws that impact objects/tasks
- New financial laws limit what certain user can do
- UI design maximize technology that supports
global UI for different countries - List of values control instead of traditional GUI
drop down for more flexible format searching - Progressive disclosure of country based formats
- The experience make the complexity transparent
and seamless to user

16Topic 2 7 Myths of Usability ROI
17Key Questions
- Why are we still talking about this (CHI, UPA,
etc.)? - I have never been asked for an ROI justification
at a software company - Why is that?
- Inadequacy of current Usability ROI models
- Where do these numbers come from?
- Are they real?
- Why wont your CEO believe them?
- Is there a more strategic approach?
- Where should we be looking to measure our success?
18Conventional Usability ROI theory
- Good usability increases
- Sales Market Share
- Customer satisfaction
- Profitability
- Poor Usability leads to
- Higher training costs
- Higher support costs
- Longer schedules
- Proposes various formula to quantify and case
studies to justify these
19Where do the ROI numbers come from?
- Consultants looking to convince clients of their
fee structure - Google search on Usability ROI led to
- 96 different HF/UE consulting firms websites
- 40 citations on one book (Cost Justifying
Usability) - 100 references to Debra Mayhew
- Small set of published studies
- Cited repeatedly (by each other)
- Most are ambiguous with incomplete data
- Did not document related business variables
20Myth 1Generalization is valid
- Without user centered design, a user
interface typically has around 40 flaws that can
slow users and lead to errors - Landauer (1995) The trouble with computers.
MIT Press. - Is this Hardware or Software?
- Is this Web Store front, a packaged application
or an internal IT project?
21Myth 2 Calculation of ROI cost from the
producer perspective
- Research by Gartner Group reveals that in
corporate practice, the average annual bill for
supporting a single PC is 13000. - Gibbs, Taking Computers to Task (1997)
Scientific American. - Not good for the customer
- Extra support cost is someone elses
revenue/employment opportunity!
22Myth 3You can ignore the other factors
- Revenues for one DEC product that was
developed using UCD techniques increased 80 for
the new version and usability was cited as the
second most significant improvement. - Wixon Jones (1995) Usability for fun and
profit. - What was the number 1 reason? Doubling the size
of the sales force, increasing their commission?
Reducing the price of the product 75?
23Myth 4Analog Comparisons are not required
- Cost of bad web design Loss of approximately
50 of potential sales from the site as people
cant find stuff - Jakob Nielsen (1998) Alert box (cited by
Forrester) - Compared to what?
- Do you buy something in 50 of the brick and
mortar stores you go into when shopping? - Can you find a part at Home Depot 50 of the
time? - People often dont know what they are looking for.
24Myth 5All usability are spent effectively
- Creative Good offered the striking
revelation that a dollar spent on advertising
during the 1998 holiday season produced 5 in
total revenue, while a dollar spent on customer
experience improvements yielded more than 60 - M. Rauterburg, website (2003)
- Assumes a level of effectiveness that does not
generally exist in the profession
25Myth 6Executives will believe voodoo economics
- There are 1 billion users on the internet and
half of them could come to your site. If the
average cost of an abandoned shopping cart is 20
you will lose 10 billion a year in sales of your
designer pet food - Rosenberg (2003) Parody of J. Nielsen
- Will get you coverage in NewsWeek, etc.
- Will then be cited as fact by Gartner and
Forrester Research groups
26Myth 7 UE resources will reduce schedule
- 15 week project becomes an 11 week project
- With a 13,000 investment in UE
- Overall project costs are reduced by 8,000
- Total time on the project is reduced by 4 weeks
-
- Friedland and Innes (2003) UPA workshop
- Software schedules are immutable!
- Most software engineering is evolutionary today
- Schedule ends when you run out of time, money or
features
27Laws of gravity affecting usability ROI
- Cheaper to fix problems early in the design
process - Automation reduces complexity faster and in
larger increments than UI design can - Globalization reduces labor costs
28Replace the Myths
- Stop looking in the mirror
- Start looking out the window
- Define usability value by contribution to
- Your customers success (TCO)
- Not the producers ROI
29External Customers cost
- Total cost of ownership (TCO)
- Implementation
- System administration
- Deployment and consulting implementations
- Operational Productivity
- Labor costs to perform service transactions
- Time to manufacture product
- Utilization of customer resources
30Internal Sales team
- Not the sales numbers
- Cant correlate with a single factor like
usability - The sales force
- Win/Loss reports
- Provide CIF data during sales cycle
- Analyst and Press reports
31Internal Support team
- To get faster answers to customer
- Web UI with knowledge base
- To maximize customer uptime
- Remote maintenance
- Hosting
- Reduce customers training costs
32The business product ecosystem
- Good product design (features, performance, cost,
reliability and usability) -
- Good execution (manufacturing, distribution,
sales and marketing) -
- Enough profit to stay in business because you
have successful customers that can pay you
33Rosenbergs practical rule of software product
ROI relevance
- 10 of the worlds software generates 90 of
the software industry revenue - therefore
- If your product is not in that 10 there is no
return. - To be in the profitable 10 usability is
necessary but not sufficient.
