Paper Prototyping: The 10-Minute Practical Guide

In the high tech world of digital design, sometimes the best method is still pen and paper. 

To this day, paper prototypes continue to be not only viable, but also widely used. In this article we’ll talk about when to use them, why they can help, and how to make one to suit your own needs.

What Is Paper Prototyping?

As you might have guessed, paper prototyping is sketching screenshots on paper as substitutes for digital representations. What you might not have guess, there are actually different levels of complexity.

The most basic paper prototypes are sketches of each screen. In a demonstration or usability test, the sketches are switched according to user actions.

However, due to the popularity of prototyping on paper, several advanced tools are available to facilitate the process. You can use stencils to quickly and accurately recreate buttons and icons, and even mock phone cases to better depict how the product form will look.

A step above these are paper prototyping kits, which still cost significantly less than design software. These include pre-made sheets, templates, and tools to make paper prototyping even easier, and step up the realism a little. In fact, UXPin got its start making paper prototyping kits, and business was good enough to launch our digital  app.

At the most advanced stage, you can upload photos of your paper sketches into digital prototyping software, and add actual interactions. 

Advantages and Disadvantages

Obviously, paper prototyping is not a complete substitute for digital prototyping. It does, however, have some advantages its higher-fidelity counterpart does not. Let’s review the paper prototyping advantages and disadvantages as we described in The Ultimate Guide to Prototyping.

Advantages:

  • Rapid iteration — No one wants to throw out a digital prototype that took hours to make, but few shed tears over a 5-minute sketch. Prototyping on paper lets you create — and throw away — multiple versions without wasting time.
  • Inexpensive — Paper is of course cheap, and even additional tools and kits won’t break the bank. 
  • Increased creativity — The freedom of pencil and paper facilitates experimentation and new ideas more than software, which is limited by their features and the designer’s familiarity.
  • Team-building — Don’t underestimate the effects of fun arts and crafts in a business environment. Drawing, cutting, and pasting together can build team unity and raise spirits.
  • Less learning curve — Everyone can sketch ideas, which makes paper prototyping a great way to get other departments like marketing, development, or even stakeholders involved.
  • Automatic documentation — Paper prototypes are, themselves, a tangible document. Notes can be written directly on them for future iterations, and they can be left in full view as a reminder of what they taught.

Disadvantages:

  • No gut reactions — So much of UX design comes from the user’s gut reactions on using the product. However, there’s just no way to replicate the experience of using a digital product on paper, no matter how detailed it is.
  • Inaccurate feedback — Paper prototypes require a great deal of imagination, and there’s a lot lost when imagining what a product will be like. What the users are thinking may be different than what you are, but the feedback doesn’t reflect this.
  • Extra steps — Paper prototyping is often the end in itself, begging the question “is this necessary?” Considering how streamlined the usability of digital prototyping apps are, it might be quicker to build digital lo-fi prototypes with software than to spend time with paper and later move to the software anyway. Of course, as mentioned before, apps like ours allow you to integrate photos of paper sketches, so it doesn’t have to be a waste.

When to Paper Prototype

Jake Knapp of Google Ventures is starkly against paper prototyping, but even he admits it’s useful for early-stage conceptualizing.

With its drawbacks in mind, you can understand paper prototypes’ limitations in testing high-fidelity graphics, usability, and gut reactions. Even elements like navigation and information architecture seem out of bounds.

That said, paper prototyping is perfect for early stage conceptualizing. Its speed, ease, and simplicity, not to mention automatic documentation, make it far better suited for experimenting with new ideas than more complex digital prototypes.

Paper prototypes are ideal for:

  • Brainstorming meetings and sessions
  • Light usability testing early on

The farther along in the design process you get, the less effective paper prototypes become. The exception is if you want to explore a complete experimental deviation in the later stages.

Call to action (CTA)

A call to action is a marketing term that refers to a prompt that invokes a response leading to a sale. When referring to a call to action (CTA) in the digital design world we usually mean the interactive element that leads to the next step in the experience - something that needs to be clicked or tapped.

User testing

User testing refers to a technique used in the design process to evaluate a product, feature or prototype with real users. There are several reasons why you might want to undergo usability testing, the most common is that it allows the design team to identify friction in a user experience they are designing, so that it can be addressed before being built or deployed.

WYSIWYG

WYSIWYG (pronounced WIZ-ee-wig) is an acronym for "What You See Is What You Get". It helps identify an an interface that allows user input resulting in an output that is rendered in a similar way. For example; a word processor application interface might resemble a piece of paper,so when printed the user can see how the output will appear.

Content Management System

A content management system (CMS) is an tool that allows a website editor/administrator to manage the content that is displayed. Websites are made of HTML and CSS to create pages. Pages can be hard-coded but would require technical development skills to make changes. A CMS usually allows a person without coding knowledge to amend existing and add new content to a website using a WYSIWYG interface.

Responsive Web Design

Responsive web design refers to a web page that dynamically adapts its layout to fit the size and orientation of the device on which it is viewed. A responsive design allows for a more optimised user experience across desktop and laptop computers as well as smartphones and tablets of varying sizes.

User Stories

User stories allow the functionality of a product or service to be expressed as written descriptions of an experience as seen from the users perspective. The writing of user stories creates a list of design and development tasks to complete in order to create any required functionality.

User Interface

A user interface (UI) is a conduit between human and computer interaction - the space where a user will interact with a computer or machine to complete tasks. The purpose of a UI is to enable a user to effectively control a computer or machine they are interacting with, and for feedback to be received in order to communicate effective completion of tasks.

Personas

A persona in UX Design is the characterisation of a user who represents a segment of your target audience. On a project you might create any number of personas to be representative of a range of user needs and desires. The solutions you design must answer these needs in order to deliver value to your target audience.

Card sorting

A great, reliable, inexpensive method for discovering patterns in how users would expect to find content or functionality. Card sorting is used to test the taxonomy of data with a group of subjects, usually to help inform the creation of the information architecture, user flow, or menu structure on a project.

Brainstorming

A technique used to generate ideas around a specific topic. Often done in groups, but can be done individuals. The process usually involves writing down all ideas around a topic onto paper, a whiteboard or stickies often implying some kind of association.

Minimum Viable Product

An MVP is a product that has the minimum set of features to prove the most essential hypothesis for a product. Businesses building a new product can create a Minimum Viable Product to prove that an idea is viable and warrants further investment. A further benefit being that the next stage of development can be informed by feedback obtained from testing that MVP.

Sitemap

A sitemap is a diagrammatic representation of a hierarchical system. It usually depicts the parent-sibling relationship between pages in a website, showing how sub pages might be arranged underneath their parent groupings. This arrangement forms a map of the site.

User journey

A user journey represents a sequence of events or experiences a user might encounter while using a product or service. A user journey can be mapped or designed to show the steps and choices presented as interactions, and the resulting actions.

Prototype

A prototype is draft representation built to test ideas for layout, behaviour and flow in a system. Prototypes are an indispensable tool for resolving a large number of potential issues in a concept or business before too many resources are deployed to put a design into production.

Wireframes

A Wireframe is a visual schematic that conveys a basic level of communication, structure and behaviour during the design of a system. Wireframes are low-fidelity designs that bypass including a detailed user interface or visual design, conveying just enough to get across the core idea.

Usability

To say something is usable is a qualitative statement about how easy that thing is to use. Usability is an assessment of how learnable a system is and how easy a user finds it to use. The usability of a system or product is a key factor in determining whether the user experience is a good one.

Information Architecture

Information architecture is the design and organisation of content, pages and data into a structure that aids users understanding of a system. A more organised system enables users to more easily find the information they require and complete the intended tasks.

UI Design

User Interface Design is the discipline of designing software interfaces for devices, ideally with a focus on maximising efficiency, responsiveness and aesthetics to foster a good user experience.

UX Design

The practice of User Experience (UX) Design is the coming together of many specific design related disciplines to improve the usability, responsiveness, uptake and aesthetics of a product or service.

User Experience

A general term that covers all aspects of a user's participation while engaging with something that has been designed. Usually when talking about User Experience in the digital design field it refers to the interactions, reactions, emotions and perceptions while using an app, service, website or product.
