User Experience by Mind Map: User Experience

1. UX is ... a person’s perceptions and responses that result from the use or anticipated use of a product, system or service.

2. Elements

2.1. Findability

2.1.1. Search engine strategy

2.1.2. Marketing

2.1.3. Brand management

2.1.4. Naming

2.1.5. Word of mouth

2.2. Utility (Usefulness)

2.2.1. Appropriate for purpose

2.2.2. Expected functionality

2.2.2.1. Ensure the suitability of a task

2.2.3. Expected information

2.2.3.1. Focus on information of interest to users, not on the things you want to promote

2.2.3.2. Communicate immediately at the top of the page that your content is indeed interesting and useful to users

2.2.4. Uniqueness

2.2.5. Differentiation

2.3. Usability

2.3.1. Usability is ... the extent to which a system, product or service can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.

2.3.2. "Nowadays acceptance for bad Usability decreases permanently"

2.3.3. Usability experts prioritize the problems with impact to the user, product managers prioritize with impact to the achieved result

2.3.4. Learnability

2.3.4.1. Choose appropriate UI patterns

2.3.4.2. Strive for consistency

2.3.4.2.1. “users spend most of their time on other websites than your site.”

2.3.4.2.2. “The most important consistency is consistency with user expectations”—William Buxton

2.3.4.2.3. Use standards

2.3.4.2.4. Use signifiers

2.3.4.2.5. Over time, strive for continuity, not consistency

2.3.4.2.6. UI Text Styleguide

2.3.4.2.7. UI Text Standard

2.3.4.2.8. Gestalt principles

2.3.4.4.1. Things that are not only designed to do something, but that are designed to look like they are designed to do something. A button that looks like a physical object you can push, for example, is an affordance designed so that someone unfamiliar with the button will still understand how to interact with it.

2.3.4.5. Use animated transitions

2.3.4.5.1. The user feels time passing faster than it does

2.3.5.4. Cognitive Workload

2.3.5.4.1. “The trick is to find the middle ground—the ‘sweet spot’—that enables people to benefit from variety and not be paralyzed by it. Choice is good, but there can be too much of a good thing.”—Barry Schwartz

2.3.5.4.2. Emphasize the Call To Action (CTA)

2.3.5.4.3. Eleminate unnecessary features and then hide what you can't eliminate

2.3.5.5.1. Make text size changeable

2.3.5.5.2. Use short sentences

2.3.5.5.3. Write in active voice

2.3.5.5.4. Smartphone: Show most important info on the top 2-screen-heights

2.3.10. Consider the Kulturmodell von Hofstede

2.4. Joy of Use

2.4.1. Aesthetics

2.4.1.1. "It has been shown that perceived aesthetics has a correlation with the perceived usability"

2.4.1.2. Senkt Stresspegel und vermindert Fehler

2.4.1.3. Why does one choose to use Gmail over Yahoo, Medium over Blogger — if the features are 99% the same? It’s definitely not about disrupting usability standards. It’s about that additional layer of sophistication that can only be achieved when you put enough time and brainpower into the tiniest details, the most subtle animations, the most elegant transitions – not just for the sake of creating whimsical dribbble shots.

3.3.13.1. 1D: words should be simple to understand, and written in such a way that they communicate information easily to the end user.

3.3.13.2. 2D: visual representations are all graphics or images, essentially everything that is not text. They should be used in moderation, so as to not overwhelm.

3.3.13.3. 3D: physical objects or space refers to the physical hardware, whether it’s a mouse and keyboard, or a mobile device a user interacts with.

3.3.13.4. 4D: time is the length that the user spends interacting with the first three dimensions. It includes the ways in which the user might measure progress, as well as sound and animation.

3.3.13.5. 5D: behavior was added by Kevin Silver in his article, What Puts the Design in Interaction Design. It is the emotions and reactions that the user has when interacting with the system.

4. Effects

4.1. Better product

4.1.1. Increased customer satisfaction and loyalty

4.1.1.1. This is extremely difficult to measure, and should be used as a primary cost justification only in extreme cases. That said, one method of measuring customer loyalty is in terms of customer retention. (Important especially in organizations that know when their customers are most likely to defect to a competitor or a more mature product offering.) The calculation takes into account the cost of new customer acquisition and amortizes the cost over the average customer retention period. Increasing average customer retention is a cost savings for the company, and can cost justify UX & usability work related to customer loyalty. The metrics of success will come from sales and marketing.

4.1.2. Deeper insights

4.1.3. Revenue boost

4.1.3.1. Either incremental revenue from add-ons or through an easier sales process, which is typically called "conversion rate" though that often gets mixed up with "website conversions". The metrics for this are typically found in the sales and finance department. Coupled with the estimated costs of usability testing and UX development, you'll be able to work out over what timeframe it will take for the UX work to pay for itself.

4.1.4. Increased retention

4.1.5. Recommendations more likely

4.1.6. Decreased stress level

4.1.6.1. Stress => schnell, aber hohe Fehlerquote

4.2. Reduced costs

4.2.1. Reduced cost of late correction

4.2.2. Reduced training and support costs

4.2.2.1. If customers generate calls or support tickets or other uncompensated overhead costs to the business, then those costs should be measured. The easiest way to do this is how airlines handle the it. When a passenger, for example, calls an agent to check flight status, the airline knows how long that call will last, and based on the average cost/minute for phone agents (including salary, benefits, and overhead like the phone line, office space, electricity, etc), the airline can assign a $ value to the cost of the call. Because airlines handle large volumes of calls every day, if there is an increase of 2500 check flight status calls/day at a cost of $2.00/call (theoretical cost!), then we could expect that would increase uncompensated support costs by $5,000/day. If the airline wanted to do a $50,000 eye tracking usability study to get that number down to 1225 calls/day (assuming a clean 50% improvement), then that usability study would pay for itself in 20 days.

4.2.2.2. Be wary in cases where training and support are part of the company's core business model - otherwise it doesn't make sense to decrease these costs, (i.e., if the company's revenues are earned from consulting)

4.2.3. Increased productivity

4.2.3.1. Most often found when there are large pools of employees completing certain repetitive tasks. Metrics are found in operations, HR, and finance (for overhead items like office space, equipment, etc.) For example, if you optimize the UX on a series of screens so that what was once a 5 minute task is now a 2.5 minute task, then you've increased a person's productivity by 100%. That's huge. HUGE. If the company has 100 phone agents who have an average salary of $40,000 + benefits (~$8,000) (+ an unknown amount for overhead), you could either release or retask those agents on other activities with a savings of $2,4000,000/year. (half of 100 agents x $48,000)

4.2.4. Reduced code maintenance

4.3. Less risk

4.3.1. Reduces the risk of building the wrong thing

4.3.2. Projects fails without happy users

4.3.2.1. 70% fail because not accepted by the user

4.4. Faster development

4.4.1. Avoids rework

4.4.1.1. Again, this is a function of the number of developers needed to complete project work. Bad UX is often a reflection of poor design and complexity in the underlying code. A hallmark of good UX is the elimination of unnecessary or marginal features. This reduces the complexity of the code base, making it more robust and less buggy. As a wise man once said, "there are no bugs in the code you don't write."

4.4.2. Reduces Development time

4.4.2.1. Measured in terms of development resources and time to market. For example, if moving to a system with design patterns and object oriented CSS will decrease the need for an additional UX hire and 5 developer hires (a reasonable ratio), then that's a cost savings of all of those non-hires salaries + benefits + overhead (computers, software, office space, desk, etc). Similarly, if a strong UX framework decreases the development time from 6-months to 3-months for a project that will increase revenues by $100k per month, then bringing the project to market 3 months early adds $300k to this year's revenues.

4.4.3. UI is major part of Dev Phase

4.4.4. Better ability to deliver to deadline

4.4.5. Reduced development waste

4.5. Higher ROI

4.5.1. Always estimate ROI in terms of annual dollars

4.5.1.1. Of course, all of these increases/savings must be compared to the costs associated with UX, usability, and development endeavors. I recommend that all metrics be stated in the terms of increases/decreases over the course of a year - annualized costs - because that’s a term the folks in budgeting will understand, and a dollar amount that provides the most realistic impact. (Not too much, not too little.) So, if your project is designed to increase revenue by 20% on a million dollar revenue stream, then the dollar amount should be reported as "$200k annually."

4.5.2. Companies focusing on UX peform better than their peers

4.5.3. Spend 10% to get 83%

4.6. Sell UX

4.6.1. Show horror video clips from usability test sessions to executives.

4.6.2. Don't talk about theoretical effects, show them results in your own area.

4.6.3. Start with ...

4.6.3.1. Management

4.6.3.2. Corporate Vision

4.6.3.3. R&D

4.6.3.4. Product Development Process

4.6.3.4.1. Is there time for user research?

4.6.4. Capture your audience’s attention—using emotion versus logic.

4.6.5. Hold your audience’s attention and maintain their interest.

4.6.6. Understand what benefits a company wants from UX.

4.6.7. Move senior leaders to a favorable action—an offer.

4.6.8. What Sells?

4.6.8.1. Positive emotion

4.6.8.2. simple UX tools everybody can understand

4.6.8.3. listening

4.6.8.4. case studies

4.6.9. What doesn't sell?

4.6.9.1. Representing UX as the only answer

4.6.9.2. Relying too much on ROI arguments

4.6.9.3. Using UX jargon
