Using paper prototypes in UX

In UX research we are told again and again that to ensure truly user-centered design, it’s important to test ideas with real users as early as possible. There are many benefits that come from introducing the voice of the people you are designing for in the early stages of the design process. The more feedback you have to work with, the more you can inform your design to align with real needs and expectations. In turn, this leads to better experiences that are more likely to succeed in the real world.It is not surprising then that paper prototypes have become a popular tool used among researchers. They allow ideas to be tested as they emerge, and can inform initial designs before putting in the hard yards of building the real thing. It would seem that they’re almost a no-brainer for researchers, but just like anything out there, along with all the praise, they have also received a fair share of criticism, so let’s explore paper prototypes a little further.

What’s a paper prototype anyway? 🧐📖

Paper prototyping is a simple usability testing technique designed to test interfaces quickly and cheaply. A paper prototype is nothing more than a visual representation of what an interface could look like on a piece of paper (or even a whiteboard or chalkboard). Unlike high-fidelity prototypes that allow for digital interactions to take place, paper prototypes are considered to be low-fidelity, in that they don’t allow direct user interaction. They can also range in sophistication, from a simple sketch using a pen and paper to simulate an interface, through to using designing or publishing software to create a more polished experience with additional visual elements.

Different ways of designing paper prototypes, using OptimalSort as an example

Showing a research participant a paper prototype is far from the real deal, but it can provide useful insights into how users may expect to interact with specific features and what makes sense to them from a basic, user-centered perspective. There are some mixed attitudes towards paper prototypes among the UX community, so before we make any distinct judgements, let's weigh up their pros and cons.

Advantages 🏆

  • They’re cheap and fastPen and paper, a basic word document, Photoshop. With a paper prototype, you can take an idea and transform it into a low-fidelity (but workable) testing solution very quickly, without having to write code or use sophisticated tools. This is especially beneficial to researchers who work with tight budgets, and don’t have the time or resources to design an elaborate user testing plan.
  • Anyone can do itPaper prototypes allow you to test designs without having to involve multiple roles in building them. Developers can take a back seat as you test initial ideas, before any code work begins.
  • They encourage creativityFrom both the product teams participating in their design, but also from the users. They require the user to employ their imagination, and give them the opportunity express their thoughts and ideas on what improvements can be made. Because they look unfinished, they naturally invite constructive criticism and feedback.
  • They help minimize your chances of failurePaper prototypes and user-centered design go hand in hand. Introducing real people into your design as early as possible can help verify whether you are on the right track, and generate feedback that may give you a good idea of whether your idea is likely to succeed or not.

Disadvantages 😬

  • They’re not as polished as interactive prototypesIf executed poorly, paper prototypes can appear unprofessional and haphazard. They lack the richness of an interactive experience, and if our users are not well informed when coming in for a testing session, they may be surprised to be testing digital experiences on pieces of paper.
  • The interaction is limitedDigital experiences can contain animations and interactions that can’t be replicated on paper. It can be difficult for a user to fully understand an interface when these elements are absent, and of course, the closer the interaction mimics the final product, the more reliable our findings will be.
  • They require facilitationWith an interactive prototype you can assign your user tasks to complete and observe how they interact with the interface. Paper prototypes, however, require continuous guidance from a moderator in communicating next steps and ensuring participants understand the task at hand.
  • Their results have to be interpreted carefullyPaper prototypes can’t emulate the final experience entirely. It is important to interpret their findings while keeping their limitations in mind. Although they can help minimize your chances of failure, they can’t guarantee that your final product will be a success. There are factors that determine success that cannot be captured on a piece of paper, and positive feedback at the prototyping stage does not necessarily equate to a well-received product further down the track.

Improving the interface of card sorting, one prototype at a time 💡

We recently embarked on a research project looking at the user interface of our card-sorting tool, OptimalSort. Our research has two main objectives — first of all to benchmark the current experience on laptops and tablets and identify ways in which we can improve the current interface. The second objective is to look at how we can improve the experience of card sorting on a mobile phone.

Rather than replicating the desktop experience on a smaller screen, we want to create an intuitive experience for mobiles, ensuring we maintain the quality of data collected across devices.Our current mobile experience is a scaled down version of the desktop and still has room for improvement, but despite that, 9 per cent of our users utilize the app. We decided to start from the ground up and test an entirely new design using paper prototypes. In the spirit of testing early and often, we decided to jump right into testing sessions with real users. In our first testing sprint, we asked participants to take part in two tasks. The first was to perform an open or closed card sort on a laptop or tablet. The second task involved using paper prototypes to see how people would respond to the same experience on a mobile phone.

Context is everything 🎯

What did we find? In the context of our research project, paper prototypes worked remarkably well. We were somewhat apprehensive at first, trying to figure out the exact flow of the experience and whether the people coming into our office would get it. As it turns out, people are clever, and even those with limited experience using a smartphone were able to navigate and identify areas for improvement just as easily as anyone else. Some participants even said they prefered the experience of testing paper prototypes over a laptop. In an effort to make our prototype-based tasks easy to understand and easy to explain to our participants, we reduced the full card sort to a few key interactions, minimizing the number of branches in the UI flow.

This could explain a preference for the mobile task, where we only asked participants to sort through a handful of cards, as opposed to a whole set.The main thing we found was that no matter how well you plan your test, paper prototypes require you to be flexible in adapting the flow of your session to however your user responds. We accepted that deviating from our original plan was something we had to embrace, and in the end these additional conversations with our participants helped us generate insights above and beyond the basics we aimed to address. We now have a whole range of feedback that we can utilize in making more sophisticated, interactive prototypes.

Whether our success with using paper prototypes was determined by the specific setup of our testing sessions, or simply by their pure usefulness as a research technique is hard to tell. By first performing a card sorting task on a laptop or tablet, our participants approached the paper prototype with an understanding of what exactly a card sort required. Therefore there is no guarantee that we would have achieved the same level of success in testing paper prototypes on their own. What this does demonstrate, however, is that paper prototyping is heavily dependent on the context of your assessment.

Final thoughts 💬

Paper prototypes are not guaranteed to work for everybody. If you’re designing an entirely new experience and trying to describe something complex in an abstracted form on paper, people may struggle to comprehend your idea. Even a careful explanation doesn’t guarantee that it will be fully understood by the user. Should this stop you from testing out the usefulness of paper prototypes in the context of your project? Absolutely not.

In a perfect world we’d test high fidelity interactive prototypes that resemble the real deal as closely as possible, every step of the way. However, if we look at testing from a practical perspective, before we can fully test sophisticated designs, paper prototypes provide a great solution for generating initial feedback.In his article criticizing the use of paper prototypes, Jake Knapp makes the point that when we show customers a paper prototype we’re inviting feedback, not reactions. What we found in our research however, was quite the opposite.

In our sessions, participants voiced their expectations and understanding of what actions were possible at each stage, without us having to probe specifically for feedback. Sure we also received general comments on icon or colour preferences, but for the most part our users gave us insights into what they felt throughout the experience, in addition to what they thought.

How to create a UX research plan

Summary: A detailed UX research plan helps you keep your overarching research goals in mind as you work through the logistics of a research project.

There’s nothing quite like the feeling of sitting down to interview one of your users, steering the conversation in interesting directions and taking note of valuable comments and insights. But, as every researcher knows, it’s also easy to get carried away. Sometimes, the very process of user research can be so engrossing that you forget the reason you’re there in the first place, or unexpected things that come up that can force you to change course or focus.

This is where a UX research plan comes into play. Taking the time to set up a detailed overview of your high-level research goals, team, budget and timeframe will give your research the best chance of succeeding. It's also a good tool for fostering alignment - it can make sure everyone working on the project is clear on the objectives and timeframes. Over the course of your project, you can refer back to your plan – a single source of truth. After all, as Benjamin Franklin famously said: “By failing to prepare, you are preparing to fail”.

In this article, we’re going to take a look at the best way to put together a research plan.

Your research recipe for success

Any project needs a plan to be successful, and user research is no different. As we pointed out above, a solid plan will help to keep you focused and on track during your research – something that can understandably become quite tricky as you dive further down the research rabbit hole, pursuing interesting conversations during user interviews and running usability tests. Thought of another way, it’s really about accountability. Even if your initial goal is something quite broad like “find out what’s wrong with our website”, it’s important to have a plan that will help you to identify when you’ve actually discovered what’s wrong.

So what does a UX research plan look like? It’s basically a document that outlines the where, why, who, how and what of your research project.

It’s time to create your research plan! Here’s everything you need to consider when putting this plan together.

Make a list of your stakeholders

The first thing you need to do is work out who the stakeholders are on your project. These are the people who have a stake in your research and stand to benefit from the results. In those instances where you’ve been directed to carry out a piece of research you’ll likely know who these people are, but sometimes it can be a little tricky. Stakeholders could be C-level executives, your customer support team, sales people or product teams. If you’re working in an agency or you’re freelancing, these could be your clients.

Make a list of everyone you think needs to be consulted and then start setting up catch-up sessions to get their input. Having a list of stakeholders also makes it easy to deliver insights back to these people at the end of your research project, as well as identify any possible avenues for further research. This also helps you identify who to involve in your research (not just report findings back to).

Action: Make a list of all of your stakeholders.

Write your research questions

Before we get into timeframes and budgets you first need to determine your research questions, also known as your research objectives. These are the ‘why’ of your research. Why are you carrying out this research? What do you hope to achieve by doing all of this work? Your objectives should be informed by discussions with your stakeholders, as well as any other previous learnings you can uncover. Think of past customer support discussions and sales conversations with potential customers.

Here are a few examples of basic research questions to get you thinking. These questions should be actionable and specific, like the examples we’ve listed here:

  • “How do people currently use the wishlist feature on our website?”
  • “How do our current customers go about tracking their orders?”
  • “How do people make a decision on which power company to use?”
  • “What actions do our customers take when they’re thinking about buying a new TV?”

A good research question should be actionable in the sense that you can identify a clear way to attempt to answer it, and specific in that you’ll know when you’ve found the answer you’re looking for. It's also important to keep in mind that your research questions are not the questions you ask during your research sessions - they should be broad enough that they allow you to formulate a list of tasks or questions to help understand the problem space.

Action: Create a list of possible research questions, then prioritize them after speaking with stakeholders.

What is your budget?

Your budget will play a role in how you conduct your research, and possibly the amount of data you're able to gather.

Having a large budget will give you flexibility. You’ll be able to attract large numbers of participants, either by running paid recruitment campaigns on social media or using a dedicated participant recruitment service. A larger budget helps you target more people, but also target more specific people through dedicated participant services as well as recruitment agencies.

Note that more money doesn't always equal better access to tools - e.g. if I work for a company that is super strict on security, I might not be able to use any tools at all. But it does make it easier to choose appropriate methods and that allow you to deliver quality insights. E.g. a big budget might allow you to travel, or do more in-person research which is otherwise quite expensive.

With a small budget, you’ll have to think carefully about how you’ll reward participants, as well as the number of participants you can test. You may also find that your budget limits the tools you can use for your testing. That said, you shouldn’t let your budget dictate your research. You just have to get creative!

Action: Work out what the budget is for your research project. It’s also good to map out several cheaper alternatives that you can pursue if required.

How long will your project take?

How long do you think your user research project will take? This is a necessary consideration, especially if you’ve got people who are expecting to see the results of your research. For example, your organization’s marketing team may be waiting for some of your exploratory research in order to build customer personas. Or, a product team may be waiting to see the results of your first-click test before developing a new signup page on your website.

It’s true that qualitative research often doesn’t have a clear end in the way that quantitative research does, for example as you identify new things to test and research. In this case, you may want to break up your research into different sub-projects and attach deadlines to each of them.

Action: Figure out how long your research project is likely to take. If you’re mixing qualitative and quantitative research, split your project timeframe into sub-projects to make assigning deadlines easier.

Understanding participant recruitment

Who you recruit for your research comes from your research questions. Who can best give you the answers you need? While you can often find participants by working with your customer support, sales and marketing teams, certain research questions may require you to look further afield.

The methods you use to carry out your research will also have a part to play in your participants, specifically in terms of the numbers required. For qualitative research methods like interviews and usability tests, you may find you’re able to gather enough useful data after speaking with 5 people. For quantitative methods like card sorts and tree tests, it’s best to have at least 30 participants. You can read more about participant numbers in this Nielsen Norman article.

At this stage of the research plan process, you’ll also want to write some screening questions. These are what you’ll use to identify potential participants by asking about their characteristics and experience.

Action: Define the participants you’ll need to include in your research project, and where you plan to source them. This may require going outside of your existing user base.

Which research methods will you use?

The research methods you use should be informed by your research questions. Some questions are best answered by quantitative research methods like surveys or A/B tests, with others by qualitative methods like contextual inquiries, user interviews and usability tests. You’ll also find that some questions are best answered by multiple methods, in what’s known as mixed methods research.

If you’re not sure which method to use, carefully consider your question. If we go back to one of our earlier research question examples: “How do our current customers go about tracking their orders?”, we’d want to test the navigation pathways.

If you’re not sure which method to use, it helps to carefully consider your research question. Let’s use one of our earlier examples: “Is it easy for users to check their order history in our iPhone app?” as en example. In this case, because we want to see how users move through our app, we need a method that’s suited to testing navigation pathways – like tree testing.

For the question: “What actions do our customers take when they’re thinking about buying a new TV?”, we’d want to take a different approach. Because this is more of an exploratory question, we’re probably best to carry out a round of user interviews and ask questions about their process for buying a TV.

Action: Before diving in and setting up a card sort, consider which method is best suited to answer your research question.

Develop your research protocol

A protocol is essentially a script for your user research. For the most part, it’s a list of the tasks and questions you want to cover in your in-person sessions. But, it doesn’t apply to all research types. For example, for a tree test, you might write your tasks, but this isn't really a script or protocol.

Writing your protocol should start with actually thinking about what these questions will be and getting feedback on them, as well as:

  • The tasks you want your participants to do (usability testing)
  • How much time you’ve set aside for the session
  • A script or description that you can use for every session
  • Your process for recording the interviews, including how you’ll look after participant data.

Action: This is essentially a research plan within a research plan – it’s what you’d take to every session.

Happy researching!

Why user research is essential for product development

Many organizations are aware that staying relevant essential for their success. This can mean a lot of things to different organizations. What it often means is coming up with plenty of new, innovative ideas and products to keep pace with the demands and needs of the marketplace. It also means keeping up with the expectations and needs of your users, which often means  shorter and shorter product development life cycle times.  While maintaining this pace can be daunting, it can also be seen as a strength, tightening up your processes and cutting out unnecessary steps.

A vital part of developing new (or tweaking existing) products is considering the end user first. There really is no point in creating anything new if it isn’t meeting a need or filling a gap in the market. How can you make sure you are hitting the right mark? Ask your users.  We look into some of the key user research methods available to help you in your product development process.

If you want to know more about how to fit research into your product development process, take a read here.

What is user research? 👨🏻💻

User experience (UX) research, or user research as it’s commonly referred to, is an important part of the product development process. Primarily, UX research involves using different research methods to gather qualitative and quantitative data and insights about how your users interact with your product. It is an essential part of developing, building, and launching a product that truly meets the needs, desires, and requirements of your users. 

At its simplest, user research is talking to your users and understanding what they want and why. And using this to deliver what they need.

How does user research fit into the product development process? 🧩🧩

User research is an essential part of the product development process. By asking questions of your users about how your product works and what place it fills in the market, you can create a product that delivers what the market needs to those who need it. 

Without user research, you could literally be firing arrows in the dark, or at the very best, working from a very internal organizational view based on assuming that what you believe users need is what they want. With user research, you can collect qualitative and quantitative data that clearly tells you where and what users would like to see and how they would use it.

Investing in user research right at the start of the product development process can save the team and the organization heavy investment in time and money. With detailed data responses, your brand-new product can leapfrog many development hurdles, delivering a final product that users love and want to keep using. Firing arrows to hit a bullseye.

What user research methods should we use? 🥺

Qualitative ResearchMethods

Qualitative research is about exploration. It focuses on discovering things we cannot measure with numbers and typically involves getting to know users directly through interviews or observation.

Usability Testing – Observational

One of the best ways to learn about your users and how they interact with your new product is to observe them in their own environment. Watch how they accomplish tasks, the order they do things, what frustrates them, and what makes the task easier and/or more enjoyable for your subject. The data can be collated to inform the usability of your product, improving intuitive design and what resonates with your users.

Competitive Analysis

Reviewing products already on the market can be a great start to the product development process. Why are your competitors’ products successful? And how well do they behave for users? Learn from their successes, and even better, build on where they may not be performing as well and find where your product fills the gap in the market.

Quantitative Research Methods

Quantitative research is about measurement. It focuses on gathering data and then turning this data into usable statistics.

Surveys

Surveys are a popular user research method for gathering information from a wide range of people. In most cases, a survey will feature a set of questions designed to assess someone’s thoughts on a particular aspect of your new product. They’re useful for getting feedback or understanding attitudes, and you can use the learnings from your survey of a subset of users to draw conclusions about a larger population of users.

Wrap Up 🌯

Gathering information on your users during the product development process and before you invest time and money can be hugely beneficial to the entire process. Collating robust data and insights to guide the new product development and respond directly to user needs, and filling that all-important niche. Undertaking user experience research shouldn’t stop at product development but throughout each and every step of your product life cycle.

Moderated vs unmoderated research: which approach is best?

Knowing and understanding why and how your users use your product is invaluable for getting to the nitty gritty of usability. Delving deep with probing questions into motivation or skimming over looking for issues can equally be informative. 

Put super simply, usability testing literally is testing how usable your product is for your users. If your product isn’t usable users often won’t complete their task, let alone come back for more. No one wants to lose users before they even get started. Usability testing gets under their skin and really into the how, why and what they want (and equally what they don’t).

As we have been getting used to video calling regularly and using the internet for interactions, usability testing has followed suit. Being able to access participants remotely has allowed us to diversify the participant pool by not being restricted to those that are close enough to be in-person. This has also allowed an increase in the number of participants per test, as it becomes more cost-effective to perform remote usability testing.

But if we’re remote, does this mean it can’t be moderated? No - remote testing, along with modern technology, can mean that remote testing can be facilitated and moderated. But what is the best method - moderated or unmoderated?

What is moderated remote research testing?

In traditional usability testing, moderated research is done in person. With the moderator and the participant in the same physical space. This, of course, allows for conversation and observational behavioral monitoring. Meaning the moderator can note not only what the participant answers but how and even make note of the body language, surroundings, and other influencing factors. 

This has also meant that traditionally, the participant pool has been limited to those that can be available (and close enough) to make it into a facility for testing. And being in person has meant it takes time (and money) to perform these tests.

As technology has moved along and the speed of internet connections and video calling has increased, this has opened up a world of opportunities for usability testing. Allowing usability testing to be done remotely. Moderators can now set up testing remotely and ‘dial in’ to observe participants anywhere they are. And potentially even running focus groups or other testing in a group format across the internet. 

Pros of moderated remote research testing:

- In-depth gathering of insights through a back-and-forth conversation and observing of the participants.

- Follow-up questions don’t underestimate the value of being available to ask questions throughout the testing. And following up in the moment.

- Observational monitoring noticing and noting the environment and how the participants are behaving, can give more insight into how or why they choose to make a decision.

- Quick remote testing can be quicker to start, find participants, and complete than in-person. This is because you only need to set up a time to connect via the internet, rather than coordinating travel times, etc.

- Location (local and/or international) Testing online removes reliance on participants being physically present for the testing. This broadens your ability to broaden the pool, and participants can be either within your country or global. 

Cons of moderated remote research testing:

- Time-consuming having to be present at each test takes time. As does analyzing the data and insights generated. But remember, this is quality data.

- Limited interactions with any remote testing there is only so much you can observe or understand across the window of a computer screen. It can be difficult to have a grasp on all the factors that might be influencing your participants.

What is unmoderated remote research testing?

In its most simple sense, unmoderated user testing removes the ‘moderated’ part of the equation. Instead of having a facilitator guide participants through the test, participants are left to complete the testing by themselves and in their own time. For the most part, everything else stays the same. 

Removing the moderator, means that there isn’t anyone to respond to queries or issues in the moment. This can either delay, influence, or even potentially force participants to not complete or maybe not be as engaged as you may like. Unmoderated research testing suits a very simple and direct type of test. With clear instructions and no room for inference. 

Pros of unmoderated remote research testing:

- Speed and turnaround,  as there is no need to schedule meetings with each and every participant. Unmoderated usability testing is usually much faster to initiate and complete.

- Size of study (participant numbers) unmoderated usability testing allows you to collect feedback from dozens or even hundreds of users at the same time. 


- Location (local and/or international) Testing online removes reliance on participants being physically present for the testing, which broadens your participant pool.  And unmoderated testing means that it literally can be anywhere while participants complete the test in their own time.

Cons of unmoderated remote research testing:

- Follow-up questions as your participants are working on their own and in their own time, you can’t facilitate and ask questions in the moment. You may be able to ask limited follow-up questions.

- Products need to be simple to use unmoderated testing does not allow for prototypes or any product or site that needs guidance. 

- Low participant support without the moderator any issues with the test or the product can’t be picked up immediately and could influence the output of the test.

When should you do moderated vs unmoderated remote usability testing?

Each moderated and unmoderated remote usability testing have its use and place in user research. It really depends on the question you are asking and what you are wanting to know.

Moderated testing allows you to gather in-depth insights, follow up with questions, and engage the participants in the moment. The facilitator has the ability to guide participants to what they want to know, to dig deeper, or even ask why at certain points. This method doesn’t need as much careful setup as the participants aren’t on their own. While this is all done online, it does still allow connection and conversation. This method allows for more investigative research. Looking at why users might prefer one prototype to another. Or possibly tree testing a new website navigation to understand where they might get lost and querying why the participant made certain choices.

Unmoderated testing, on the other hand, is literally leaving the participants to it. This method needs very careful planning and explaining upfront. The test needs to be able to be set and run without a moderator. This lends itself more to wanting to know a direct answer to a query. Such as a card sort on a website to understand how your users might sort information. Or a first click to see how/where users will click on a new website.

Planning your next user test? Here’s how to choose the right method

With the ability to expand our pool of participants across the globe with all of the advances (and acceptance of) technology and video calling etc, the ability to expand our understanding of users’ experiences is growing. Remote usability testing is a great option when you want to gather information from users in the real world. Depending on your query, moderated or unmoderated usability testing will suit your study. As with all user testing, being prepared and planning ahead will allow you to make the most of your test.
