=Overview=
Usability, is a metric used to asses assess a User Interface design. An interface is considered “usable” if it is perceived as easy, enjoyable, efficient and effective to learn and use. If you use, test, configure or administrate a SmartSimple System you have a role to play in ensuring your system is and stays usable.This article provides information on how to you test for, and ensure you do not introduce usability issues into your system?.
=Usability – Essentials=
==What is UI and UX?==
UI or User Interface, is the look and feel and interaction between you and the system. The user interface is a series of screens with elements such as buttons and icons that you use to interact with the SmartSimple System. If you add a custom field or change a color in your systems you are modifying the User Interface.
UX or User experience is how we feel about interacting with a system. This term was coined by Don Norman and encompasses all aspects of the user's interaction with the company, its services, and its products. UX is how you feel when you buy a product, take it out of the store, open the box. It is the entire experience of a system from buying, using and disposing of that product or service.
A bad UI will create a bad UX.
==What is a usability issue?==
A usability issue, is any issue that prevents the system from being easy, efficient and effective to learn and use. Usability issues are objective , such as contrast ratio of text on a background. Usability issues are not subjective or based on personal preference , such as “I don’t like orange”.
==How can a I test for usability issues?==There are established standards that are used to evaluate the usability of a user interface design. They are called Heuristics and there are 10 of them which we have contexed contexted and summarized below. You can also learn more about heuristics in general on this external site https://www.nngroup.com/articles/ten-usability-heuristics/
==What are the 10 Heuristics?==
You can meet these criteria by:
* Show Showing progress (how far have you gone and what is left)* Show Showing space/time (how much space/time is left)* Show Showing change (draw attention to things that have changed)* Show Showing expected actions (tell me what I need to do next)
===2. Match Between the System and Real World===
You can meet these criteria by:
* Use Using familiar words, phrases, concepts and metaphors* Follow Following conventions* Present Presenting information in a logical order* Provide Providing a preview or show showing the world in miniature
===3. User Control and Freedom===
Make sure users can go forward and back in any process and make sure they can see the information the way they need.
Ask yourself : can I easily find the information I am looking for in the way I need to see it?
You can meet these criteria by:
* Providing a path forward and back (undo/redo)
* Provide Providing different ways to explore information (searching, filtering, viewing options)
===4. Consistency and Standards===
Make sure buttons and links are named the same thing, are located in the same place, and put where they are expected to be. Ask yourself : do I know where to find desired links and buttons, do I know what they do, and are they always in the same place? You can meet these criteria by:
===5. Error Prevention===
Prevent errors by providing more information, add instructions, check for error conditions, and refine your process.
Ask yourself : what are common errors with my process and how can I help prevent others from encountering these?
You can meet these criteria by:
* Providing needed information and warnings , so users know what to do
* Make sure links and button captions say what they will do (never say “click here”)
* Eliminate error -prone conditions or check for them and advise the user
* Refine your process to avoid errors
===6. Recognition Rather Than Recall===
Make sure all the information and instructions needed to complete an action are available.
Ask yourself : are all instructions and information I need available so I can take the appropriate action?
You can meet these criteria by:
* Make Making objects, actions , options and directions visible or easily retrievable* Don’t force Not forcing the user to remember anything or think* Avoid Avoiding codes and hurdles* Provide Providing visual representations
===7. Flexibility and Efficiency of Use===
Help users accomplish their goals faster by adding shortcuts and default options.
Ask yourself : can we help the user accomplish their goals faster and with less effort?
You can meet these criteria by:
* Add Adding shortcuts to commonly used functionality* Provide Providing default options* Use Using list views with options where possible
===8. Aesthetic and Minimalist Design===
Make sure what the user came to see or do is visible and clear, and eliminate anything that may distract them.
Ask yourself : is it clear what I am supposed to do and is there anything distracting me from completing my task?
You can meet these criteria by:
* Keeping important information above the fold (initial viewable area)
* Minimize Minimizing signal-to-noise ratio* Be Being judicious with color* Remove Removing redundant information (keep it concise)
===9. Help Users Recognize, Diagnose and Recover from Errors===
Help users understand and fix errors with clear messaging that explains the problem and how they should resolve the error.
Ask yourself : when I encounter a problem, do I know what I did wrong, and how to fix it?
You can meet these criteria by:
* Ensure Ensuring clarity of messaging and use plain language* Always provide providing or suggest a solution* Educate Educating the user (what is happening and why)* Provide Providing a path forward
===10. Help and Documentation===
Help users understand what is expected of them and how to do it by including context -sensitive instructions, highlighting new features and changes in functionality.Ask yourself : is my help documentation where it is needed, can my users understand what they need to do and are my users aware of new functionality and changes?
You can meet these criteria by:
* Providing context-sensitive help* Providing examples and recommendations* Pointing out new or changes to functionality* Guiding with additional information* Listing concrete steps to be carried out* Being short and concise ==How do I ensure my system is and stays user -friendly?==Weather Whether you are making changes to your system or if you have a team making changes for you, always use the above heuristics to test the work. If you find an issue , bring it up with your team or call support. Most issues can be resolved through configuration, but if you encounter something that is not, raise an enhancement ticket and help make SmartSimple better for everyone. Help for specific issues and features can also be found on the wiki.
