Sketch Plugins for User & Usability Testing 2021

All graphic designers must agree that the designing process can get really frustrating and time-consuming when it comes to continuous corrections after the client’s feedback. This, as a result, negatively affects the workflow, impairs productivity and even worse – can lead creators to burnout. While many emerging artists and aspiring graphic designers look for the best free drawing software to ease their workflow, such programs often lack advanced sketching tools. Besides, free programs sometimes serve up poor user experiences and might stifle artists’ creativity.

However, there are ways to avoid this and bring in the balance as well as to boost the performance when sketching designs. It has never been easier to achieve desirable results faster because 2021 rewards the designers with a variety of Sketch Plugins to run user and usability testing.

If you are not familiar with Sketch Plugins for User & Usability testing, or plugins in general, don’t worry, keep on reading. In this article we will tell you the benefits of using plugins for Usability Testing and User Research as well as our top picks that will speed up your workflow in 2021.

Installing Sketch Plugins

Let’s start with just clarifying what plugins are. In simple words, a plugin is a piece of software that adds a specific feature and functionality to a certain program and makes it work smoother.

The main benefits that the plugins provide are: decreased workload, saved time and money, optimized work process, flexibility and many other great features that certain plugins can give.

Installing the plugin is so simple, it takes just a few easy steps. Here are the general steps on how to install a Sketch Plugin: 

  1. Download the plugin you want to use
  2. Double-click on downloaded file to install it
  3. Once you have your plugin installed, you can access all its features and manage them in computer preferences > plugins.

Sketch plugins for user testing help to assess how potential users would interact with the created design. It provides designers with insights on what parts of the design would work well and what elements, perhaps, shouldn’t be added. The earlier designers discover problems in the development process, the more it will save them time and of course, money.

Why it is important to do user and usability testing

Regardless of the knowledge and experience level, designers tend to make assumptions about how the design will perform.

Even though the design might look nice, professional, and functional for the designer who created it, however, in many cases the expectations don’t live up. This is why it is important to do actual testing, and get real, useful insights from others. 

User & Usability testing is a valuable procedure when it comes to developing product design. It allows designers to understand how actual users would interact with the product. Testing gathers information that helps designers to identify the issues. Simply put, it makes real people use the products and provides feedback, based on which designers make changes to improve the product.

Before entering the development state, habitual product testing makes the workflow less repetitive. Helps to achieve desirable results faster and boosts productivity plus, it’s pretty easy to do it.

“Any product that lacks usability will waste more time and energy.”

So, now, when it’s much more clear what plugins are, why usability testing is important and what benefits it brings, let’s dive into the top Sketch Plugins for User and Usability testing.
