Design Thinking - Part 3
Prototyping and Testing are two important stages in the Design Thinking model that help realize and test your ideas and solutions to solve problems for customers. So what is Prototyping and Testing? What is the purpose and meaning of these 2 stages in the process of building and completing the idea?
  1. Prototype

A prototype is something that makes your ideas “real enough to feel,” so you can get feedback from users.

In the fourth stage of Design Thinking, Prototyping is the process of modeling ideas by prototyping to test the possibility of realizing a generated idea.

The main aim of Prototyping stage is to gain empathy. It creates conditions to bring new information and learn about customer behavior. The goal is to test ideas, or validate your assumptions about a specific solution.

The result from the Prototyping process helps you to identify strengths, limitations and problems present in your ideas, thereby continuously improving ideas and launching products / services. Whether one or a part of the concept, they all need to be designed so that users can feel authentic enough to give appropriate suggestions.

There are many ways to create a prototyping, the simplest example is drawing on paper or using readily available materials to create a model. In addition, you can prototype through images, product sample videos and post them on websites, advertising. Even 3D printing technology has been used to give users the most realistic experience.

Prototyping process helps businesses capture user responses and opinions, thereby improving or enhancing products. Not only users understand what features this product has, or how this product solves problems for them, but also help the company learn more about its customers, specifically about their demand, trends, behavior and habits. Moreover, Prototyping is the most realistic verification of the company's ideas. It helps the company know which products/services need to develop their strengths and weaknesses to optimize the user’s experience.

“They slow us down to speed us up. By taking the time to prototype our ideas, we avoid costly mistakes such as becoming too complex too early and sticking with a weak idea for too long.” - Tim Brown - Chairman of IDEO Global Innovation and Design Consulting.

  1. Test

Located in the final stage of the Design Thinking model, Testing is the process of testing the performance of the idea, as well as the final evaluation step for the whole idea building process.

You test with users to refine your solution and also to refine your understanding of the people for whom you are designing.

It is essential to ask open-ended questions in conducting a user test. You only need user’s opinions, not sales, so do not become a saleperson or ask something directly related to the product.

If the Prototyping phase helps to realize and bring the concept model to the user, then Testing is conducted to detect the error of the concept in each specific condition to fix and correct. The main purpose of testing is to help the idea meet the essential requirements, including standards for product / service design and stakeholder requirements (users, customers, legal regulations). Testing can be done at any time during conceptual development.

In addition, information obtained about the quality of products / services from the inspection process is provided to businesses and stakeholders (users, partners) to allow them to evaluate and consider the risks involved in implementing the idea. Information about the concept template will also be used to refine the idea development later. If an investor decides to invest in a product / service, they will judge the acceptable ability of the user in that product / service. Testing is the process to help them make some assessments.

In a nutshell, Prototyping and Testing are two stages that play an important role in realizing, testing and evaluating ideas / solutions. It makes a chance for your business to have new initiatives to improve product / service quality and especially to help optimize user experience.
