I had no slides during the presentation since Iwas asked to replace Charles last minute.
I prepared these slides to capture what wespoke about and more.

Origins Usability has its roots in the fields of Ergonomics and Human
Factors which began early in the 20th century. Here are someimportant events: 1911: Frederick Taylor publishes Principles of Scientific Management which describes time
and motion studies and methods for improving industrial efficiency. 1943: Alphonse Chapanis shows that "pilot error" can be greatly reduced through the more
intuitive layout of airplane cockpits. 1954: Paul Fitts publishes a paper that describes a mathematical model used to predict the
time it takes to move to a target based on its size and distance. 1956: George Miller coins the phrase "the magic number seven plus or minus two" from a
variety of experimental results indicating that humans have trouble holding more than five tonine items (chunks) simultaneously in working memory.
1983: The Psychology of Human Computer Interaction is published by researchers atCarnegie Mellon and Xerox Park (Stuart Card, Thomas Moran & Allen Newell).
1985: J. Gould and Clayton Lewis publish the influential paper, "Designing for Usability: KeyPrinciples and What Designers Think." They discuss an early and continual focus on usersas well as empirical measurement and iterative design.
Usability is the core of User Experience

UX is Important
@Ergonaute
UX Needs to be Planned Each project is different and UX can take many
shapes and forms. Before we go blindly into a design direction, we
need to identify and focus on the designattributes that will bring more value to thebusiness and that will satisfy the user’s needs.

UX Design Attributes
@Ergonaute
UX is backed by Science
Usability is the measure ofhow easily, efficientlyand satisfyinglydifferent types of userscan accomplish differenttasks towards differentgoals Usability Objectives
Satisfaction
Effectiveness
Efficiency
Usability is the science behindUX Design. It allows to measurehow good a design is.

UX has Layers and Specialties

@Ergonaute
It Requires Specialized Resources Unless the product is very small and the cost of
changing it is minor (such as a mobile appdeveloped by 1 or 2 developers), you needspecialized resources to: Design the User Interface, Navigation, etc. Evaluate an existing design. Improve processes. Perform user research. Create Style guides. Identify what needs to be improved and how. Etc.
The minimum is to hire someone to plan UX.
Why is UX Important?

Do I need to get into UXDesign?Where do I start?

Should the PM get into UX? Product Managers need to make sure UX is in
place whether it is under their umbrella or not. UX is part of product strategy, definition and design UX impacts product marketing UX is part of analytics and optimization. If you want the product to succeed, you need to make
sure someone is looking after UX.
@Ergonaute
Can a PM become the UX Resource? Yes if he has the right background. Yes if he has no budget, even for a quick 2-day review. Otherwise, the PM can work closely with UX teams or
resources. You may understand users’ needs from market research
and user feedback, but you need to know the scienceand the techniques to translate this to proper design.
The moment you think you know what users wantbecause you are a user, let a UX specialist do the jobbecause users are very different.

What UX is not Graphics. These are only 1 layer. UX is not makeup on top of a badly
designed system. Layout: True usability is about efficiencies in work practices,
processes and features. It is about innovation performed very early. Features. UX uncovers features users do not tell you, then design
them properly. However fewer well designed features are better thantoo many.
Part of development. UX belongs to business and happens duringplanning and specifications. User interface design specifications areexecuted during development. In small companies, when all roles aremerged into a small team, UX becomes part of this team, even if thelead is a developer.
Opinions. PM/Dev: “I am a user and I think it should be this way” iswrong. UX research is about all users and measures how they, withtheir differences, react to designs. It is about facts and science. Userswill suggest things beyond stakeholders’ imagination.
@Ergonaute
What UX is not Functional specifications. The UX tools gather user data differently
and offers much more information that lead to better decisions. Market research. User research is richer and goes beyond the what
and where to include the how and why. Incremental changes and patches. UX looks at the end to end user
experience. Adding small changes and functions over time candestroy usability if the overall design concept is not maintained.
User Interface Development. Differentiate between User InterfaceDesign (UX) and User Interface Development (programming)
A product feature. It is a process that needs to be executed beforedevelopment or needs to be integrated into the current processes.
Ad hoc, on the fly. It is a process, had methods and guidelines It requires user involvement, iterations and testing It requires specialists applying appropriate methodologies. It does take time & budget

Where to Start Plan UX with a specialist. UX is user centric. Real users need to be involved, not friends and
colleagues. UX is iterative. Give time for design iterations. UX is measurable. Results often show you need to redesign. Test as
early and often as you can. Engage all departments to share the results and ensure buy in. Design before you even think of developing, especially for large or
complex products. The UX lifecycle starts before the project and ends when the product
is retired. UX also happens after launch. It is about continuousimprovement.…
UX can be an innovation vehicle if done early and properly.
