What is Usability Testing?
Usability testing evaluates the ease with which the software can be used. It helps to identify operating problems with a software design much early in the life cycle so that it can be easily fixed.
It checks for the learning time to use the software, handling controls flexibility, understandability of what to perform next, and also the likeness of using the software. It is also known as User Testing or UX Testing.
Needs for Usability Testing
Usability testing purpose is to identify usability problems with a design as early as possible so they can be fixed before the design is implemented. usability testing is often conducted on prototypes rather than on developed products.
Features of Usability Testing
Features of Usability Testing are as follows:
- Usability testing is a non-functional testing technique.
- It is usually conducted on developing prototypes at the initial stage.
- It offers visibility on end-user expectations.
- It identifies various usability errors in the software product.
- It provides input on the way real users use the software system or applications.
- It ensures that the software product meets its purpose.
- It tests the usefulness, accessibility, traceability, usability, and desirability of the software.
Phases of Usability Testing
Following are the phases of usability testing:
Prepare your product or design to test
The first phase of usability testing is to choose a product and then developed the prototype to perform usability testing. Hence this is one of the most important phases in usability testing.
Find your participants
In the second phase of usability testing is to find an employee who will be performing usability testing. Generally, the number of participants that you need based on a number of case studies.
Write a test plan
This is the third phase of usability testing where the test plan is developed for the steps going to be performed in usability testing. The main purpose of the plan is to document what you are going to do, how you are going to conduct the test, what metrics you are going to find, the number of participants you are going to test, and what scenarios you will use.
Take on the role of moderator
This is the fourth phase of usability testing where the moderator plays a pivotal role by building a partnership with the participant. The feedback provided is incorporated into building the software.
Present your findings
This generally involves combining the results into an overall score and presenting it meaningfully to the audience.
Goal of Usability Testing
The goal of this testing is to satisfy users and it mainly concentrates on the following parameters of a system:
The effectiveness of the system
The effectiveness of the system is all about verifying how effective the system is for use? It checks if the system is easy to learn and satisfies user experience and expectations. Various factors like Color, Icons, Images, Logo are taken into consideration while deciding the effectiveness of the system.
Efficiency describes how easily any operations can be performed in the system. It verifies the uniformity in the format of screens in the software application. Navigation, scroll bars, filters, sorting, etc. are important factors to decides the efficiency of the system.
Accuracy makes sure that there are no mistakes present in the application. There should not be any broken links, outdated or incorrect data like contact information/address should be present.
It checks if the application is user friendly and helps the users to understand the application and perform any operation. The controls should be self- explanatory, unsuccessful/ successful messages must have a satisfactory explanation.
Advantages of Usability Testing
- It helps in validating the usability of the software.
- It Ensures the satisfaction of users with the software product.
- It validates the efficiency and effectiveness of the software product.
- It helps discover potential bugs and defects in the software product.
- It enhances the acceptability and reliability of the software product.
- It helps in Identifying changes required to improve user performance and satisfaction.
- It helps to Analyze if the software meets the usability objective.
