Apple Inc. Copyright terms and licence: CC BY 2. Users of all ages love the Apple MacBook. This is an example of how simplicity reduces intimidation and allows a wider range of users to be unafraid to use the product.
Simplicity is not easy to define or measure. Joe Sparano, an American graphic designer and design educator says it best:. Whether your website acts as an online retailer for consumers or your product is an enterprise solution designed to help company executives manage their projects, maintaining clarity in the user interface you design is key to user success and user satisfaction.
If your design has too much extraneous information, users will have trouble navigating your site. Call attention to only the core aspects of the page you want your users to focus their attention to.
Websites are catching on to the value of simplicity in design but there is still a lot of work to do! Copyright terms and licence: Fair Use. One of them is by staying true to simplicity by maintaining clarity.
It is unclear as to whether Yahoo intends for the user to browse aimlessly or randomly select a popular new story that may be completely irrelevant and distracting to what the user is searching for.
Help your users understand what actions they can take by calling attention to only the core aspects you want them to focus on. This refers to the tendency for humans to perform common, practiced tasks with a minimum amount of conscious, cognitive effort. Take for example the toaster. The toaster is simple to use and requires very few interactions to achieve appliance-related goals. A two slice Sunbeam toaster from is an example of how an interface designed for automation stands the test of time.
Another example would be messenger apps that show little variance in appearance between the different mobile interface designs. With a familiar interface and common functionality , users are easily able to adapt to different messenger apps.
Two different messenger apps, similar mobile user interface components. Remember: Make use of automation by designing for the least amount of cognitive effort. Figure out what the commonly practiced tasks and processes are and incorporate them into your designs whenever possible.
The best user interfaces lead users through a desired path with clear indication of the individual steps required to complete their user goals. In order to make information scent strong, we can limit the options for the user to consider in our user interface. You want to make sure parent functions are presented consistently across all the children.
A starting point is looking for CRUD actions create, read, update, and delete. As I am modeling Twitter and checking that objects are complete, I would notice this omission. In this case, the lack of an update function is intentional, but it could also have been overlooked. In my experience overlooked basic functions are not uncommon. It can also be helpful to look at objects that serve a similar function and compare them.
Should users be able to favorite a Direct Message as well? A common problem with systems that have grown over time or have functions built by different teams is inconsistent vocabulary. Sometimes inconsistencies are relatively minor Edit vs.
Update but they can also be foundational Task vs. One reason to more completely fill out the actions and attributes for each object rectangle is to do a thorough vocabulary cross-check. The model can ultimately serve as a source for a controlled system vocabulary. During screen-level design work, the object model can serve as a reference to make sure there is a clear association between an object and its associated actions. I consider object modeling a skill in my UX tool belt, along with conducting research, facilitating workshops, journey mapping, persona development, and the like.
These are all inputs which, depending upon the needs of the project, contribute to successful design outcomes. For additional perspectives on object modeling for design, I invite you to explore these other resources:.

All articles June 27th, Object Modeling for Designers: An Introduction As a user experience designer, it can feel as though I am waging an on-going, never-ending battle against complexity, especially when working on enterprise systems. This is where an object model can help. Roots of object modeling The whole idea of interface objects stems from the development of the graphical user interface GUI.

Identifying objects Below is a screen capture of a Tweet from Twitter. The button bar bottom and menu right can be a source for identifying objects.
Looking at the menu labels, I can see that one noun is a Tweet. Here are our object rectangles so far: A set of initial object rectangles. Narrative Object Model describing the relationships between objects. The descriptions help illuminate the purpose of each object in context of the larger whole: An Account can send a Direct Message An Account can publish Tweets Tweets can be curated into groups call Moments Again you could stop your model at this point, after the relationships have been defined, if you feel the model serves your purpose.
In an object, the actions are listed in the bottom pane of the object rectangle, as shown below. The object Tweet with its associated actions. Attributes are what characterize each instance of an object; they listed are in the middle pane of the object rectangle, as shown below for the Tweet object: The object Tweet with attributes middle pane and actions lower pane.
These include: Indicating which objects are the core system objects in bold outline Using traditional UML line-end treatments to characterize relationships further Using color to associate objects with a similar purpose Indicating core system objects Not every object is of equal importance in a system. Indicating specific types of object relationships In the model, it can be helpful to represent specific types of relationships.
The four main types of relationships are: Association Aggregation Component Inheritance Association relationship The simplest type of relationship is an association. An association relationship, indicated by a plain line.
Aggregation relationship An aggregation relationship indicates an object that is merely a collection or list of other objects.
An unfilled diamond notates an aggregation relationship. An aggregation relationship, indicated by an unfilled diamond. Component relationship A component relationship is a type of dependency relationship where one object is a component of another. A component relationship is notated by a filled-in diamond. For instance, as soon as a list is exposed in Java, this list can be modified by a subclass or an external library which would produce unexpected behavior at a later point in the program execution.
This adds an element of complexity to the language which would not be there in a language where all data is immutable. This does not mean that a program written in an object-oriented programming language is inherently complex. I personally am a functional programming enthusiast who spends an enormous amount of her time writing Java programs a typical object-oriented language. However, I still attempt to make my code as simple as possible by using the Java 8 Stream API, by eliminating mutable state as much as absolutely possible hello final keyword!
It is also not true that just because a program is written in a functional programming language it is automatically simple. Personally, I love the Clojure programming language because I think in a functional way and the language allows me to write out a program exactly how I have formulated it in my head. However, one of the critiques I have heard about the language is that the entire state of the program is often saved in one huge global map which is then given as an argument for many functions within the program.
If you want to change the structure of the map, you then have to update all of the functions which take this structure for granted. This criticism is justified because having to know the structure of the map has complected it together with all functions that accept it as an argument.
My first step would always be to try to eliminate as much of the state as absolutely possible. If the remaining state is too complicated, we can add a level of abstraction by using one of Clojures datatypes like records or writing a single function responsible for updating the global state that then delegates to smaller functions.
This is similar to object-oriented encapsulation apart from the fact that immutability is not sacrificed. We live in the real world, and often the task at hand is really difficult. There is some essential complexity that we will never be able to get rid of. However, we should strive to minimize the amount of unnecessary complexity present in our applications regardless of the programming language we are using.
