Create a culture of feedback

Listen to Chapter

by Aarron Walter

Feedback is the lifeblood of a healthy design team. It informs the design process, leads to better products, and helps designers grow. Despite its essential role in design, it’s too often absent in our work.

In most design programs, feedback is folded into virtually every aspect of learning. I was reminded of this fact a couple years ago when I was invited to the Stanford d.school to speak to Enrique Allen’s class about design. Before meeting with students, Enrique provided a quick tour, pointing out works in progress. His colleague Scott Doorley joined us to explain the thinking behind each workspace in the school.

In some ways the school was like many others I’d visited—the energy of overly caffeinated students laboring over projects was palpable. But there was something peculiar about it: every space was messy. Not unkempt, but messy with ideas in progress. There was a sense of urgency to the way work was posted on walls and scribbled upon. Work tables were strewn with exacto knives, rulers, tape and scraps of paper—instruments of creation. All the furniture—desks, couches, work tables, and whiteboards—was fitted with casters and either pushed into clusters for conversation or lined up against the walls to open up room to build. The space was very carefully designed to facilitate the chaos of creative thinking.

The energy was incredible, and I didn’t want to leave. It was an ecosystem of ideas, where projects sprouted and grew or died to make room for the next experiment.

The d.school’s design studio is so different from those in nearly every tech company, where the space is pristinely decorated and filled with desks for solitary work. The walls of most startups I’ve visited are reserved for clever posters or artsy murals, not the design concepts that will lead to the next product release. Those designs remain trapped in a legion of MacBooks, starved for critical discourse that could help them grow into something far greater.

Healthy feedback

Something’s lost when we transition into the professional design world. Work no longer happens out in the open. Creative chaos is traded in for tidy presentations of fully formed ideas. Things stop being messy.

The d.school’s messy studio is an indicator of a healthy feedback process. Students are making things, showing what they’ve made, and getting feedback that helps them see their work differently. Then the process repeats, often quickly.

Healthy design teams have feedback built into their processes, so ideas can evolve and designers can grow. Work is shared with colleagues consistently and intentionally in design reviews, daily standups, and casual conversations.

Building feedback into our design practice helps in so many ways:

  • It helps us avoid spending too much time on a design that may have significant flaws.
  • It gives us multiple perspectives on a single problem, helping the designer get closer to an effective solution faster.
  • Presenting work for feedback keeps the team synced on project progress, and holds everyone accountable to milestones and deadlines.
  • As designers get in the habit of presenting their work and giving feedback to others, they learn to think more clearly about their design decisions and become comfortable articulating their ideas.
  • Regular feedback processes will give junior designers the opportunity to learn from senior designers, helping your entire team level up.

There are many ways to create a culture of feedback in your team, but be patient—change won’t happen overnight.

Creating a culture of feedback

Giving and receiving feedback is a skill that needs to be cultivated. Dropping a few design reviews on the team calendar creates the opportunity for your team to exchange feedback, but it doesn’t ensure that anyone will actually know how to participate.

It can be a little scary to give feedback—we don’t want to create conflict by coming across as negative. And receiving feedback is even more intimidating. No one wants their work to be criticized! With practice, your team will learn that these fears are misplaced. Design feedback, when properly delivered, is constructive, supportive, and helps designers grow.

As they talk about design, your team will develop the language they need to deliver constructive feedback, and their perspectives on the qualities of good design will mature. You’ll hear fewer vague observations and more constructive feedback that can improve the design. For instance, rather than hearing, “I like the type you’ve chosen,” you’ll begin to notice statements like, “The type selection feels trendy, which contradicts the project’s goal of inspiring trust in the content.” The former isn’t helpful, while the latter is instructive.

Tweaking the language used in critiques can help ensure designers don’t take criticism personally. Say “the design doesn’t meet the goals of the project,” not “you didn’t meet the goals of the project.” Always talk about the work, not the person who made it.

Good feedback develops with rapport. For that reason, you may want to temper overly critical feedback early on so people feel safe presenting their work. Designers need to hear where they’re headed in the wrong direction, but deliver the message with encouragement. Work your way into more direct criticism once rapport and trust are established.

Setting the stage

Feedback happens more naturally when you create the right environment. Does your design practice make affordances for creative chaos like the Stanford d.school does, or is it built for solitary work?

By simply changing your space, you can set the stage for feedback and collaboration in your team. For distributed and remote teams, this is doubly important. Establishing dedicated times and places for sharing works in progress keeps everyone connected.

In person

The walls of your design studio are a sacred space. This is where your team’s ideas can be shared, debated, retooled, and celebrated. Make it clear to your team that the studio walls are not a gallery—this is work space!

If you don’t already have one, invest in a large format printer and get the whole team connected. Print design work daily and post to your studio walls for scheduled design reviews and casual conversations.

If your walls aren’t ideal for posting work, you can buy 8-foot by 4-foot sheets of foam core and lean them against your walls. Get some nice Washi tape to post your designs in style (and easily peel off later). Leave markers and sticky notes nearby so your team and anyone in the company can easily jot down feedback and post it.

The design team at Greater Good Studio has gone so far as to create project bays, a modular space to post work for critical discussion. Each new project they begin gets its own bay—a physical manifestation of their progress.

The fidelity of the work you post can influence the feedback you get. Pixel perfect comps may lead others to believe the work is finished, which will inhibit feedback. Work that’s lower fidelity or with notes scribbled on it will make it clear to all that you’re still working through ideas.

Remote

Remotes teams can also set the stage for feedback using tools like Slack, Trello, Google Hangouts, and of course, InVision. The entire design team at InVision is distributed and uses their own product to conduct design reviews. LiveShare, a design collaboration feature in InVision, lets the team present and get real-time feedback. Early ideas are explored with Freehand and Boards, later becoming Prototypes that are again shared with the team for feedback.

With so many affordable tools at hand, remote teams can easily build feedback into their design process too.

Bringing everyone into the process

Once your space is set up and designs are being posted, pay attention to how people behave. In person, are more people stopping by, curious about your work? Are spontaneous conversations happening in front of design work? Do you see designers staring at the wall, head tilted, pondering what’s been posted? Online, are people commenting on work shared on Slack or InVision? Is your Trello board exploding with links to new ideas?

These are all positive signs that your culture is shifting for the better. You’re bringing everyone into the design process!

Formalizing the feedback process

Designing out in the open is just the first step. Your team will also need to get feedback on their designs, sync with teammates to make sure progress is being made, and learn from mistakes. This is a tall order and calls for different types of feedback processes.

Let’s take a look at a few ways to get your team the right feedback at the right time.

Design reviews

When they should happen: Early, midway, and at the end of a project

Who should be there: The designer plus no more than 7 people

How it helps: Designers get the feedback they need to refine their work

Design reviews are critiques that let designers get detailed feedback that’s framed by the project goals. Design reviews can happen at a number of different points in a project. It’s often helpful to do it early on so the designer can get fresh perspectives before investing too much time in an idea that may be misguided. The midway point and towards the end of a project are also natural times to get additional input.

Never use a design review as a big reveal of project. If you wait until you have everything polished, you’ll be too invested to accept the feedback you’re given.

Design reviews are a great opportunity to bring in experts from other teams. Colleagues from customer support, engineering, QA, legal, marketing, or even an executive may have a new perspective to help you see the problem differently. But try not to overload the guest list in these reviews—too many people and you’ll have a hard time guiding the conversation.

Design reviews are not a free-for-all. They should be run with these rules in mind:

Use a facilitator

The designer is not the best person to facilitate a conversation about her work. She’ll have biases that could influence the feedback, and she needs to be free to listen to the conversation unencumbered. The facilitator will write down all of the feedback and share it with the design team after the review.

A facilitator will set the ground rules for the conversation:

  • State the time limit for the design review
  • Introduce the designer and remind everyone that feedback should not turn into committee design. “Susan is the designer of the work we’re reviewing today. We’ll be helping her get fresh perspectives on her work, but let’s offer feedback—not design suggestions. She will use our feedback to inform her decisions.”
  • Let people know how they should give feedback. “Feedback should be specific and candid. Let’s point out what’s working well and what needs refinement. Remember, we’re critiquing the work, not the designer.”

Don’t rush into the review. The facilitator should give everyone time to review the work and for their observations to take shape in silence before the conversation begins.

Frame the problem

The facilitator should give the designer an opportunity to frame the problem at the beginning of the review, including any user and business goals. For example, “Users want to save money more effectively, and we want to keep customers engaged by teaching them to manage their money better.”

Identify the constraints of the project: ”Due to legal constraints, we have to disclose this information before the user can enroll in this new program.” If reviewers aren’t aware of the constraints and goals of the project, their feedback is unlikely to be helpful.

Say what you need

The designer should state what she needs from the design review: ”I’m trying to determine if this photo upload workflow is intuitive.” This will help keep the feedback focused, and prevent the group from wandering into unproductive conversations.

Don’t pitch, just listen

The designer should not pitch her idea or over-explain her designs. If she does, she robs everyone of the fresh eyes they bring to the design review. Once the designer has framed the problem and stated her needs, she should simply listen to the feedback.

Design standups

When they should happen: Daily, if possible

Who should be there: Everyone on the design team

How it helps: Your team gets the chance to sync up on projects

Design standups are short, daily check-ins that help your team stay abreast of the work being done. As the name suggests, everyone remains standing in these meetings so no one can get comfortable enough to launch into a soliloquy.

In a standup, each team member answers 3 questions:

  1. What did you do yesterday?
  2. What will you do today?
  3. Are there any impediments in your way?

While most teams choose to conduct standups in the morning, you may want to consider doing them after lunch—the morning is when our minds are clearest and ready to focus on creative work.

Don’t let standups turn into impromptu design critiques. If someone needs immediate design feedback, ask that they hold the request until after the meeting. A standup should be short and focused on project progress.

Retrospectives

When they should happen: After a project is launched or a sprint is completed

Who should be there: Everyone who worked on the project

How it helps: Your team will internalize lessons from each project

Every project is a learning opportunity, but if you don’t pause to take stock, valuable lessons will slip by. When you’ve launched a project or completed a sprint, reflect on what went well, what was confusing, and what didn’t go so well.

Matth Spiel, Director of Design at Treehouse, conducts retrospective meetings regularly. He sends a pre-retrospective survey to the team before the meeting to capture each person’s perspective individually. This helps to eliminate the bandwagon effect, which happens when the views of the group conform to those of a few vocal people.

Matt asks his team to rate their performance both as a group and as individuals on a scale from 1 to 5, where 5 is the highest. Ratings tend to cluster in a similar spot, but occasionally there are outliers. Team members who’ve given starkly different ratings are asked to share their views in the meeting to promote transparency and honesty.

Discussion in Treehouse’s retrospective meetings is centered around 3 questions common to most Agile retrospectives:

  • What worked well for us?
  • What didn’t work well for us?
  • What can we do to improve our process?

These questions are sometimes referred to as Start, Stop, Keep—what should we start doing, stop doing, and keep doing?

Honest conversation about each of these questions becomes easier with the cultivation of trust and plenty of practice running retrospective meetings.

Postmortems

When they should happen: After a project has gone poorly

Who should be there: Everyone who worked on the project and an impartial facilitator

How it helps: Your team will learn from their mistakes and find a way forward

Not all projects go well. Some go horribly wrong, requiring all teams involved in the project to come together to consider and learn from the mistakes they made.

Though projects rarely go awry at Etsy, they’ve established a strong process to guide them through those that do. Their process follows many of the recommendations set forth in the Agile methodology.

Here’s how a typical postmortem is run:

  • Before the meeting: Send an email asking the team to identify key points in the project timeline. This will be used to construct a master timeline of events, which will be discussed in the meeting. By focusing on events, you’ll avoid negative finger pointing, which can derail the process.
  • Moderator: Choose a moderator. This person, who wasn’t on the project and can be impartial, should be guiding the conversation from the whiteboard, taking notes for all to see.
  • Ground rules: The moderator should first point out that this is not a blame session. It’s a conversation about the shortcomings of the team’s process, not the people involved. It’s an opportunity to learn!
  • Facts: People recall events differently. The moderator can help the team agree upon what actually happened so lessons can be extracted. Establishing a timeline of events can help pinpoint where things went wrong.
  • Lessons and actions: As key lessons are identified, they should be written on the whiteboard for all to see. The actions required to mitigate the problems stemming from the failed project also need to be identified, assigned an owner, and provided a clear deadline.
  • After the meeting: The lessons learned from the postmortem should be emailed to the entire team, along with the action items that are to be completed.

Postmortems can seem rough, but they’re far superior to repeating the same mistakes. They’re a powerful opportunity for your team to learn and improve your processes.

Putting show and tell into practice

I’ve mentored a number of talented designers seeking guidance on their career path. All tell me the same thing: “I just want to work somewhere where I can grow and learn.” As they visit various companies, interviewing for their next design post, they can sense right away if the environment will give them the growth opportunity they crave. How? They recognize the signs of a company with a culture of feedback.

They see work on the walls. They see the messy signs of creative progress. Design critique is fluid and not limited to formal meetings. These are the signs of a healthy design team, fueled by feedback and always improving.

Building a culture of feedback takes time, but these simple steps will help you enact change:

  • Rethink your design studio: Create areas for work to be posted to foster spontaneous design discussion. It’s okay to be messy. Scribble on comps, add notes, post different versions of the same concept.
  • Stay in sync: Schedule short, daily standup meetings for your team to sync up on projects. It may be best to schedule them at the end of the day, so you don’t block the mornings when minds are most creative and ready to design.
  • Make time for feedback: Schedule design reviews for every project. They should be frequent enough for designers to get the feedback they need to avoid going too far down the wrong path.
  • Learn and grow: Schedule retrospectives after every project to capture lessons learned. When things go wrong, a postmortem meeting will help you learn from your mistakes without pointing fingers.

Hiring, coaching, and retaining great designers is made much easier when design and feedback are out in the open. Help your team show their work and tell you all about it.

Principles of Product Design

Fast feedback

Product prototyping—accelerated

Listen to Chapter

by Aarron Walter

Have you ever watched a great chef at work—the kind of chef worthy of a coveted Michelin Star? Whether she’s in the kitchen, the field, or at the market, she’s always tasting the food. Her palette guides her to the right flavors, aromas, and textures that combine to create an unforgettable meal. The alchemy of great cooking can only happen when the chef gets feedback at each step of her process.

Similarly, design teams that produce great products have something in common—they habitually test their designs. Before a single line of code is written, they build high-fidelity prototypes and put them in the hands of colleagues and customers, collecting fast feedback and correcting course before development.

These product design teams have a huge competitive advantage over those that get feedback only after their product ships: they learn faster. They spot problems quickly and fix them. They talk to customers early and align the product to their needs.

The software industry isn’t the first to grasp this principle. The animation industry was transformed by an underdog studio in Los Angeles that found a way to learn faster than the big New York studios by getting fast feedback.

Learn fast, leap forward

In the early 20th century, the boundaries of animation had been drawn and the industry was happily operating within them. The medium was crude—settings were flat, characters lacked personality, and the content was often limited to slapstick gags.

Then Walt Disney Studios changed everything.

Disney’s faith in the medium as an artform pushed the studio to experiment with new ideas that lead to astounding technical achievements. In 1928, they introduced sound with the release of Steamboat Willie, and in 1932 they introduced full color with Flowers and Trees. Each is an impressive achievement, but it was the studio’s contributions to process that enabled animation to evolve into the rich medium we know today.

In 1931, seeking faster feedback on their drawings, Disney animators began making what they called “pencil tests:” rough drawings on inexpensive negative film that they fed into the Moviola, a device with a small screen for viewing footage.

This process let Disney animators meticulously refine their drawings immediately, not weeks or months later, and enabled them to learn the art of the medium faster than any other studio. Soon the animators began stringing together pencil tests to review entire scenes, the interaction of characters, and the delivery of the story.

Walt Disney Studios’ prototyping method pushed the medium into new territory. While other studios produced silly gag films to make people laugh, Disney created art with emotionally complex characters that made audiences cry.

By building fast feedback into their creative process, Walt Disney Studios was able to make a huge leap. What worked for Disney can work for your design team too. Don’t worry, you won’t need to track down a Moviola on eBay. All you need is a high-fidelity prototype.

Prototyping and tools

Prototypes let us present product concepts to colleagues and customers without diving into the production process. A good prototype is a balancing act—it feels like a real product, but doesn’t require a lot of time to build.

I used to create prototypes using HTML, CSS, and JavaScript. It was a painful, time-consuming process that affected my judgement when testing. I’d spend a week or more producing a prototype that was vaguely realistic enough to show customers. When feedback called for big changes, I found myself reluctant to act, as the work seemed daunting.

That process seems ridiculous today, as we’re in a golden age of product design tools. We can now create prototypes that are much higher fidelity in less time without writing a single line of code. With less time invested, tweaks to a prototype come easy.

There are a number of prototyping tools on the market—more than we can cover here. Do some research to find the right fit for your needs. As you consider various prototyping tools, ask yourself these questions:

  • Is it easy to focus on product design problems, or will I be fiddling with the tool or code?
  • Can I deploy my prototype to various devices to create a realistic testing experience?
  • If you’re working remotely, is it easy to share the prototype and conduct remote testing?

InVision and Sketch

As you might’ve guessed, we’re partial to prototyping with InVision. Before joining InVision, my product design team at MailChimp used InVision to prototype new apps and explore feature concepts. It helped us move fast and get the feedback we needed. We shared InVision prototypes with the engineering team early to get feedback and keep everyone in sync.

Many product designers have transitioned from Photoshop to Sketch, which lets you work on multiple screens in a single file. You can save common UI elements like buttons and forms as shared symbols to build a screen quickly. There are a number of great learning resources to guide you if you’ve yet to make the leap to Sketch.

Craft by InVision, a suite of free plugins for Sketch and Photoshop, creates a tight integration between Sketch and InVision, shortening the prototype design process. It lets you pull real data from an API, fetch content from a site, or grab elegant photos and drop them into your design file to make your UI more realistic. Craft even lets you build a prototype directly in Sketch.

Design tools today are doing for product design what Disney’s pencil tests and the Moviola did for animation—they’re shortening the learning process so the craft can evolve faster.

Keynote

Keynote, Apple’s popular presentation software, has become a go-to prototyping tool for many designers. It’s simple enough that almost anyone can prototype with it, and sophisticated enough to do elegant animations that make a series of images feel like a real app.

Install Keynote on your iPhone or iPad to run prototypes on the target device, making the testing experience more realistic. Design prototypes in Keynote faster with Keynotopia’s UI templates for both iOS and Android. If you end up doing a lot of prototyping, you’ll probably want to take some time to create your own UI template library so you don’t have to continuously apply your brand’s colors and style to stock elements.

Faster prototyping with a pattern library

Your product prototyping process can be accelerated exponentially when you work with a pattern library—a collection of standard elements that can be combined like LEGO blocks to create a new UI. Creating a pattern library is time consuming work, but it pays off with the design of each new product or feature.

Facing UI fragmentation across many products and platforms, the design team at NASDAQ revised their schedule to spend time creating a pattern library. The process was intense, but helped them unify the user experience across all of their products. There was an additional benefit they hadn’t initially anticipated—prototyping with a pattern library helped them move very quickly.

Spending less time noodling on UI treatments means designers can focus more on aligning the product to customers’ needs. Companies like Salesforce, IBM, Atlassian, MailChimp, Spotify, and Westpac have all developed detailed design systems that help them design new products quickly.

Getting feedback on your prototype

Testing internally

With your prototype built, you can start collecting feedback. Before you put your prototype in front of customers, spend time talking with your design and engineering colleagues. They’ll help you look at the UI with fresh eyes, and reconnect with the key objectives of the project. Now’s a great time to conduct a design review.

Deploy your prototype to the devices you’ll be targeting so everyone can get a feel for the real experience. It’s not uncommon for designers to walk around the building to grab a few colleagues for an impromptu test of a prototype. Great feedback can come from unexpected places, so look beyond the design and engineering teams.

With feedback in hand, revise your prototype accordingly and get ready to test with real customers.

Testing with customers

You’re going to learn a lot as you show your product prototype to your customers. Your ideas and assumptions will be put to the test, which may at times make you uncomfortable. It can be frustrating to watch users struggle with your design.

Your instincts might lead you to help customers figure out how to use your app, but you’ll taint the feedback if you do. Instead, stick to your testing script or work with a moderator who can conduct the tests impartially.

Michael Margolis, UX Research Partner at GV, follows a very simple process as he conducts tests with customers: a welcome, an ice breaking period, the introduction of the prototype, the test, and a debrief. Michael’s script is wonderfully simple and easy to remember. Dive into his process in more detail in the book Sprint from GV.

According to research conducted by the Nielsen Norman Group, the majority of problems with your prototype will be identified after testing with just 5 customers. Instead of testing more customers, Jakob Nielsen recommends another small batch of tests after refinements have been made.

Recruiting customers

Running the test is actually the easy part of the feedback process. Finding test subjects is the hard part. If you have an existing customer base, query your database to find power users. Devout customers are often excited to see new design concepts, and will likely give more informed feedback. This is their chance to influence the design process!

If you’re testing a prototype for a brand new product, you’ll need to be more creative in how you recruit. Once again, the GV team has a clever solution. They create a form to screen customers that asks a few carefully considered questions. A worksheet guides them to create a screener that will target the right kinds of people. They post a link to their screener form on Craigslist, Twitter, Facebook, and send to an existing mailing list if available. Since you’ll only need about 5 test subjects, you don’t need a high response rate to the screener.

Be prepared to compensate your customers for their time—remember, they’re doing you a big favor by testing your prototype.

Alternatively, you could hire a professional recruiter to find customers for you. The downside is it can be very expensive, and it won’t be a hands-off process. You’ll still need to give them enough information to target the right customers.

Testing remotely

Not all the customers you recruit will live nearby. You’ll need to make plans to conduct tests remotely too. Gregg Bernstein, Senior User Researcher for Vox Media, has developed an elegant system to conduct tests with users remotely using inexpensive, freely available software—a rig that runs just $99, a small price to pay for fast feedback!

Here’s how he does it:

  • Gregg shares a Calendly link with a potential test participant, letting her select a convenient test time. Calendly also lets Gregg ask for permission to record the session, and lets him send details on what the test participant can expect.
  • The Vox design team posts a prototype to InVision.
  • Gregg invites the participant to Zoom call where the customer can use the prototype while Gregg asks questions, observes, and takes notes.
  • The session is recorded using ScreenFlow.
  • After the test session is complete, Gregg re-watches the video to fill in gaps in his notes. He then shares those notes and his insights with his Product team via Slack.

This process is simple and fast, yet effective. It lets Vox’s remote product team get feedback from users anywhere without hopping on a plane.

A service like Lookback.io can also help you get fast feedback from both colleagues and customers remotely. InVision and Lookback integrate to let you test a mobile app prototype with customers. It records the customer’s screen, their interactions with your prototype, and even overlays a video of their face as they use your app, helping you read their emotional state.

When your app is built, your developers can integrate Lookback into your app so test sessions can be triggered any time. Users can shake their phone to reveal a secret button that triggers Lookback’s recording feature. All sessions are stored in a central dashboard for designers and developers to review and make revisions.

Lindsey Campbell, UX researcher at InVision, has a unique approach to getting customer feedback remotely. She’s set up a Slack channel to share prototypes with devout customers to get early feedback and bring customers into the design process. The design team monitors the feedback and tweaks the product as needed.

Better, faster product prototyping and testing

Like a chef sampling her ingredients, designers need to get a taste of the user’s experience while designing, not just after the product ships. When you shorten the feedback loop, you can learn faster how to make a product that will appeal to your audience. Here’s some guidance to get you started.

  • When should I build a prototype? After you’ve done initial research and worked through many ideas on paper.
  • How much of the app should I build in my prototype? Don’t waste time prototyping the entire app. Focus instead on the parts about which you have the most questions.
  • How real should my prototype be? It should be real enough that customers won’t realize it’s just a prototype.
  • When should I show others my prototype? Early and often. Don’t let yourself get too far down a single path before you start getting feedback from colleagues. Show your prototype to customers after you and your colleagues have ironed out the kinks.
  • Who should I show it to? Start with the people in your design or product team. Be sure to get an engineer’s perspective to ensure the design you’re proposing is technically feasible.
  • How should I present my prototype? It’s always best to show the prototype on the target device if possible. Frame the problem you’re trying to solve before you ask for feedback from others.

We’re fortunate to know the importance of testing, and to have access to tools that make capturing feedback cheap and easy. Whether remote or in person, your team can build fast feedback into your process so you can build better products faster.
