Information architecture (IA) is a science of organizing and structuring the content of the websites, web and mobile applications, and social media software

The purpose of IA is to ensure, before continuing the design process, that it is easy for the user to use. Allowing the primary features advertised to be easily found in 5 seconds, and having the fewest clicks and scroll as possible. 

Information architecture is about helping people understand their surroundings and find what they’re looking for, in the real world as well as online.

Beginning your IA and as you continue to design the blueprint for, in this case, an app. You must consider the three systems of organization in design thinking: hierarchal, sequential and matrix.

Hierarchical Structure:

First, a designer must figure out the flow for the user that allows everything important to be easy to find. You can label this as the main idea at the top and then subcategories going down the chart with essential for the app but not for the user, at the bottom. 

Sequential Structure:

There has to be an organized step to get from point A to point B, as UX designers we must figure out the most logical steps to get through the app. For example, when using the Stop & Shop app’s feature of a shopping list would be the first step of searching for the groceries, checking the coupons available and then shop for items on your list. This step by step process will be easier for the user, instead of choosing items and then put on a shopping list. A simple and logical example rather than an extensive example. 

Matrix Structure:

UX designers will plan for a specific easy way to get from Point A to B, but the reality is the user will go through the app according to their preference. When creating wireframes and then ultimately the prototype designers should prepare for this. Which is where our refining feature will come into play. For example, when showing the coupons there should be most used, alphabetical, categorical, etc. depending on the app that is being redesigned.

After going over your IA structure and determining what and what is not necessary, a designer will move on to the wireframes that match this researched organization. 

Wireframing is the skeleton of the app that allows designers to then match a specific brand. The UX designer’s job is like being an architect when designing a dream home for a family. With a 

‘Perfect’ structure will allow the next step of prototyping easier.
