Introduction Design Thinking Prototypes

With the industry moving towards agile ways of working and fast paced delivery, user centricity and competition have become key aspects to consider for any business. If your product or service is not what the actual users need, there are 10 other competitors present in the market to eat up your customer base. With this the prime focus for any organization is to deliver a product or service which adds value to the user and solves their problem. However, how do we really add value to the customer, you can give what they want/need for themselves in terms of requirements, but:

How do you know if the solution you are building solves the problem?
What if we take 3-6 months to develop a solution and the users don’t like it?
How do we quickly validate our ideas?
What is that bare minimum thing which we can take to the users to validate?

Well, the answer to all the above questions is Prototyping which is extensively used in design thinking. Prototypes in design thinking is a quick artefact that bridges ideas and real world solutions and helps teams to validate if they are in the right direction before they start implementing the solutions. We cover various facets of Prototyping in design thinking in our workshop on Design Thinking. Reach out to us to plan a contextual and customized workshop which is aligned to your business objectives. In this blog, we aim at exploring and understanding:

What Is Prototype In Design Thinking

Prototype in design thinking is an artefact which is more than just a mock up that helps teams validate their ideas into potential feasible solutions. It is a first model or a simulation idea of a product or system that is used to test and refine ideas before the solution is fully implemented. Prototypes in design thinking helps in quickly validating an idea, gathering feedback, identifying flaws and changing quickly to implement a solution which solves the user problems.

There are various types of prototypes depending on the phase of the product, however the overarching idea behind all of them is to quickly validate the solution.They help the teams in testing assumptions and refining the solutions before it is implemented. A prototype can be made with a different set of tools available in the market and can be of different forms like Sketch, storyboards, wireframes, physical models and also a mock up with nothing integrated.

Why is prototyping essential?

The whole purpose of design thinking is to empathise with the end users and build solutions which actually solves the problems. Prototypes in design thinking helps teams in quickly validating the ideas for a solution and take feedback to narrow down on the best possible solution. Below are a few critical reasons as to why prototyping in design thinking are essential:

● Early detection of flaws:

Helps in identifying design flaws and implementation bottlenecks even before implementing the full solution

● Iterative Improvements:

With feedbacks from the user, teams can narrow down on building the right solution

● Reduces Assumptions and Risks:

When a solution is taken to the user before implementation, teams can showcase the quick idea to the stakeholders where appropriate budgeting can be made

● Promotes User Centricity:

Feedback from direct end users can help teams validate their solutions

● Fosters innovation and collaboration:

With the intention of not going with a single approach and exploring multiple possibilities to solve a problem, prototypes helps in team members coming up with multiple solutions which brings in innovationTypes and Levels Of Prototype in Design ThinkingThe basic idea behind prototypes in design thinking is to validate the idea with the end user before fully implementing the solution. This helps the teams in avoiding any assumptions, catch issues early and then reduce the blast radius. However, there are different forms and types of prototypes which can be developed in different contexts. In this section, let’s understand various types of prototypes in design thinking and their purposes.1. Low-Fidelity Prototypes (Lo-Fi)

What? – Low fidelity prototypes in design thinking are quick and simple representations of a product or idea which help designers to quickly explore and validate the ideas and get user feedback

When? – Initial ideation of a solution, validating basic concepts

Forms – Paper sketches, storyboards, rough wireframes

Advantages – Easy to modify and are not very expensive

2. Medium-Fidelity Prototypes

What? – More detailed than low fidelity prototypes which represents even more clearer view of the product which can be iteratively changed based on user feedback

When? – Usability testing, understanding navigation

Forms – App mockups, clickable wireframes

Advantages – More detailed yet flexible to change

3. High-Fidelity Prototype

What? – High fidelity prototypes are the ones which closely represent the final product in design, functionality and user experience.

When? – Final stages before implementation/development

Forms – Functional app screens, UI designs

Advantages – Helps in precise testing and take user feedback

Best Methods or Forms Of PrototypingPrototypes in design thinking play an important role in coming up with quick solutions and validating them with the users if it really solves the problem. However, there are various types of prototypes in design thinking based on the goal, level of detail needed and the stage of the design process. You can leverage a design driven innovation consultancy like NextAgile to understand and implement best working methods for your environment. Here are some types and forms of prototypes which are widely used in the industryPhysical Prototype

What? – A real time model of the product which can be used to validate and refine ideas. Gives details about ergonomics and understand form and function

When? – Ideation of hardware solutions and ergonomics testing

Forms – 3D printed models, hand crafted samples

Advantages – Helps in refining physical feel and usability

Digital Prototype

What? – An interactive simulation of a product or solution which is created using tools to visualise user experience and user interfaces

When? – Validation of software, UI/UX

Forms – website/app mockups, Wireframes, Mockups

Advantages – Helps in iterative testing without coding or starting development

Sketching and Paper Prototyping

What? – A rough simple drawing and representation of what a solution or product potentially looks like

When? – Early stage / initial stage of ideation and brainstorming

How – Paper drawing, white board drawings

Role-Playing & Storyboarding

What? – Simulation of user interactions to test the experiences

When? – Service or experience based products

How – Behaving/acting like a delivery person to capture pain points

Wizard of OZ Prototyping

What? – Faking an advance behind the scene behavior of a system or functionality

When? – Testing AI, automation or complex digital interactions

How – A chatbot prototype where a human (Wizard) manually responds to change

Ways of PrototypingPrototypes in design thinking is a continuous process as the product evolves. There are two approaches which can be used to refine ideas, improve user experience and also build better products. And they are:Iterative Prototyping

Idea – An approach where prototypes are continuously tested, refined and improved based on user feedback

Process – Build a prototype, Test it with user, gather user feedback and refine the prototype

When – This approach can be used while building a complex system which has to be built iteratively in smaller chunks based on user feedback

Benefits – Best possible product which a user wants emerges with continuous feedback

Parallel Prototyping

Idea – An approach where multiple prototypes are created at the same time and tested separately which helps choosing the best elements from each one

Process – Build multiple prototypes, Test each with different users, gather user feedback and combine best elements to make the best design

When – This approach can be used when multiple design options are being explored

Benefits – Promotes divergent thinking and considers all scenarios

Benefits Of Prototyping In Design ThinkingPrototyping in design thinking plays a vital role in innovation and problem solving and helps in building products which are user centric. It helps teams in coming up with a solution for a problem or product requirement, quickly create a solution, take it to the users, gather feedback and build a product/solution which best suits the user. Apart from this, prototypes helps in: Benefits Of Prototyping In Design Thinking

Validating the solution early from the users and arrests the risks early

Identifying usability issues and technical flaws well ahead before investing much time and resources in implementing them

Refine solutions with iterative process based on real users feedback

Promotes divergent thinking with experimentation without fear of failure

Reduces assumptions with actionable feedback items from the users

Helps teams in detail understanding of what the users are looking for

Brings everyone in the team together with shared understanding of the problem and solution to be implemented

Reduces unnecessary resources spent and help teams prioritise what needs to be developed

Improves quality with the product being tested by the users

ConclusionProduct teams and organisations are moving towards building a product which is most lovable and usable by their customers or end users. With this shift, it becomes important to understand what the users need rather than assuming what a user might need. Iterative and incremental approaches have become the way of working for many organisations to stay relevant in the industry amongst all the competition.Prototyping in design thinking is a vital step in design thinking framework which helps teams to explore ideas, test assumptions and refine them to build a solution before going ahead with full fledged development. Prototyping brings in the essence of user centricity and iterative development. Prototypes in design thinking helps teams in quickly validating the ideas for a solution and take feedback to narrow down on the best possible solution.The idea of the prototype is to reduce waste, arrest risks and flaws early before the development and to build a solution or product which actually makes sense to the user. While the idea of a prototype in design thinking is the same, there could be various types and forms of prototypes depending on the goal, stage of the design process and also the cost involved.From low fidelity sketches prototype to high fidelity interactive physical models, each type of prototype covered in the blog serves unique needs of the teams. Teams can choose what suits them based on their constraints and needs.With this our blog on “Exploring types of prototypes in design thinking” comes to an end and we sincerely hope that our readers have benefited from it.

How Do High-Fidelity Prototypes Differ From Low-Fidelity Ones?

Low fidelity prototypes are rough, quick and simple representations of a product or idea which could be in the form of sketches, drawings and are done in the initial stages of the design process. While High fidelity prototypes are the ones which closely represent the final product in design which are in the form of clickable screens, mockups which are almost ready to be implemented.2. When Should Rapid Prototyping Be Used?Rapid prototyping approach is generally used in iterative environments where pivoting is done based on quick feedback from the users. Ideally used in initial stages of product development where multiple ideas are being explored.3. What Are The Benefits Of Using Multiple Types Of Prototypes?The basic idea of prototyping in design thinking is to validate the ideas before implementing them. There are various types of prototypes which serve different purposes and goals. For example, idea generation can be done with low fidelity prototypes and usability testing can be done with medium fidelity prototypes high fidelity prototypes for final validation.4. What Are Some Best Practices For Creating Effective Prototypes?

First start with low fidelity simple prototype like sketches and drawings

Focus on the context and structure/flow rather than aesthetics

Use a simple prototyping tools

Narrow down on what you want to validate like usability, experience, pain points

Design with end users in the mind and avoid unnecessary complexity with assumptions

Take the prototype to the end users and take feedback

Refine based on the user feedback and consider appropriate levels of prototypes in different stages
