Usability Testing

Usability Testing is a type of testing, that is done from an end user’s perspective to determine if the system is easily usable. Usability testing is generally the practice of testing how to easy design is to use on a group of representative users. A very common mistake in usability testing is conducting a study too late in the design process and If you wait until right before your product is released, you won’t have the time or money to fix any issues – and you’ll have wasted a lot of effort developing your product the wrong way.

Needs of Usability Testing:
Usability testing provides some benefits and the main benefits and purpose of usability testing are to identify usability problems with a design as early as possible, so they can be fixed before the design is implemented or mass produced and then such, usability testing is often conducted on prototypes rather than finished products, with different levels of fidelity depending on the development phase.

Phases of usability testing:
There are five phases in usability testing which are followed by the system when usability testing is performed.These are given below:



  1. Prepare your product or design to test:
    In the first phase of usability testing is choosing a product and then prepare the product for usability testing. For usability testing more function and operation are required then this phase provided that type of requirement. Hence a this is one of most important phase in usability testing.

  2. Find your participants:
    In the second phase of usability testing is finding an employee who is helping you for performing usability testing. Generally, the number of participants that you need based on a number of case studies. Generally, five participants is able to find almost as many usability problems as you’d find using many more test participants.

  3. Write a test plan:
    This is the third phases of usability testing. The plan is one of the first steps in each round of usability testing is to develop a plan for the test. 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.

  4. Take on the role of moderator:
    This is the fourth phases of usability testing and the moderator plays a pivotal role that involves building a partnership with the participant. Most of the research findings are derived by observing the participant’s actions and gathering verbal feedback and to be an effective moderator, you need to be able to make instance decisions while simultaneously overseeing various aspects of the research session.

  5. Present your findings:
    This generally involves combining your results into an overall score and presenting it meaningfully to your audience. An easy method to do this is to compare each data point to a target goal, and represent this as one single metric based on percentage of users who achieved this goal.
