Principles of Product Design


by Aarron Walter

Successful design-driven companies building the best products with the strongest design teams have practices in common. These extensively researched core best practices will help your team design better, faster, and more collaboratively. Combined with the power of design thinking, these product design principles will accelerate your team’s design practice.

Guess less
Stop wasting time

The software industry celebrates stories of lightning-strike success so much, you’d think hunches and risky bets could create unicorns. The best product design teams understand the reality—customer research forms the bedrock of successful products and companies.

Story first
Find your North Star

Humans have used stories to foster collective understanding since the beginning. The most powerful designs start with a story—the why—and where your designs fit into people’s lives. Using product stories, journey maps, storyboards, and user personas, teams can build empathy and understanding before designing.

Show and tell
Create a culture of feedback

When it comes to feedback, there’s little room for polite reserve within a design team. Use design reviews, retrospectives, design standups, and careful space planning to facilitate a culture of feedback within your team—your designs and designers will benefit.

Fast feedback
Product prototyping—accelerated

Building great products requires an iterative process. The more your team tests their designs through prototyping, the faster you’ll discover needed course corrections or new possibilities. Through building blocks like pattern libraries and user feedback, teams can always design with fresh eyes.

Lateral design
We're better together

Your org chart can greatly influence the design process at your company. Bridge gaps between design, engineering, research, product, and others with cross-functional teams, sprints, working groups, and other structural changes that enable better lateral design.

Product design is people

As your company and design org mature and scale, it gets harder to maintain the visibility and transparency crucial for great product design. You’ll need to take on streamlining communication, surfacing design within the company, and more big-picture challenges beyond your desk.

Pencils before pixels

Think divergently

Listen to Chapter

The work of the modern designer lives in the abstract world of the computer, where every move we make is precise and effortless. Precision has its place, but not in the early stages of the creative process, when our ideas are still nebulous. There’s danger when creative exploration starts with perfection.

Perfection can create the illusion of certainty, something architect Frank Gehry avoids as he begins a project. It’s discovery he craves. Craig Webb, Design Partner at Gehry Partners, has heard Gehry say many times, “If I knew where I was going, I wouldn’t go there.” To Gehry, peak creativity lies in the unknown.

His process begins with rough concepts. He and his team sketch, make models, then reflect. If the outcome isn’t right, they throw it out to begin again. Crude outputs early on make the work less precious and completely malleable.

The hundreds of models and sketches that cover the walls and surfaces of Frank Gehry’s studio are the artifacts of a creative process that starts wide, where there’s space for discovery of the best ideas before committing to a single direction.

Though Gehry’s work is unique, his process is not. Many creative thinkers start wide and narrow down. Unfortunately, many software design teams take a different approach—they start narrow and refine too soon.

Steve Jobs once famously likened the computer to a bicycle for the human mind. Computers help us make short work of complicated tasks and connect us to vast amounts of data—superpowers indeed, but when misapplied they can hinder the creative process.

Computers let us jump straight to pixels—a space of precision where everything aligns to a grid, vividly colored and fully formed. Precise outputs are precious and hard to abandon. This narrows creative exploration to just a few ideas well rendered.

To find the best design solutions, we should follow Frank Gehry’s lead: crudely render many ideas to find the solution worthy of a more precise investigation.

We can make more space in our creative process for critical thinking and better design by putting pencils before pixels.

The power of a pencil

The pencil is a humble tool that’s sparked millions of great ideas. It’s the inverse of a computer; it’s simple and limited in functionality, but its limitations make it effective.

Pencils are important to the creative process because:

  1. Pencils are inclusive. They’re not just for designers—anyone can use a pencil to express their ideas clearly. The pencil is the great equalizer.
  2. Pencils are low-fi. Quick sketches give no impression of a complete thought, signaling to all that it’s okay to offer feedback.
  3. Pencils aren’t fiddly. Instead of getting lost in software settings or style, you’ll focus on your ideas.
  4. Pencils are fast. You can explore vastly different solutions to the same problem in minutes, and you won’t feel bad throwing your sketches out because you invested so little time.

There’s a magic that happens when we put our ideas on paper. Dave Gray, Founder of XPLANE and co-author of Gamestorming, describes sketching as “a conversation with yourself.” Gabriela Goldschmidt, professor emeritus at Technion Israel Institute of Technology, made similar observations in a study of the sketching practices of architects published in the Creativity Research Journal. She discovered that although sketches start from ideas already within the mind, they can mutate into the unexpected—forming new ideas. Sketching is a thinking activity!

Many product designers already know this intuitively. Stanley Wood, Design Director at Spotify, told us, “Many of our designers sketch, but just so they can think through various ideas. Most of the time they don’t show them to anyone.”

And sketching, of course, is also a powerful communication device. The design team at Slack shares sketches with colleagues to invite conversation about concepts without getting distracted by style.

The MailChimp design team discovered that sketching is an important bridge to engineering colleagues. Todd Dominey, MailChimp’s Director of Design, noticed that “Pixels freak people out!” When engineers see a high fidelity design comp, they get the impression that the important decisions have been made without them, and now they’re expected to simply execute the design. But when a sketch is presented, it’s clear that the creative process is still wide open for their participation.

No art degree required

Depending on your background, the term “sketch” might conjure images of an artist in a Parisian cafe, leisurely capturing a scene with loose lines and precise shading. But you don’t need a beret or an art degree to sketch a quick UI or communicate an idea for a product (a cappuccino won’t hurt, though). If you can scribble some text and draw boxes, you’ve got all the skills you need to sketch.

Sketching is something anyone can do—it’s not the sacred territory of designers. Inviting others to participate in the design process will help you produce a more diverse set of design solutions. Engineers, product managers, executives, lawyers—anyone with a stake in your product—can help you turn abstract ideas into concrete solutions by sketching.

Sketching ideas together

A simple activity with tight constraints can be the catalyst you need to get your team comfortable. Todd Zaki Warfel, Senior Director of Design at Workday, created a team sketching activity called 6-8-5: you and your colleagues will generate 6 to 8 design solutions per person in just 5 minutes. No one will have enough time to get lost in fancy renderings, and that’s important. After all, the idea is to focus on ideas and ditch misgivings that “I can’t draw!” In this exercise, everyone’s sketches will be messy!

Here’s how it works

    1. Get your team together—designers, engineers, product managers, and experts with important domain knowledge. Limit the group to 8 or less to keep the discussion productive.
    2. Give each person a sheet of A5 or 8.5” x 11” paper. The paper will be folded 3 times to create 6 boxes (for 6 sketches). If you want to generate more ideas, fold the paper into quarters and give everyone 2 sheets.
  1. Frame the problem for everyone, and clearly state the desired outcomes of this project. “We want to help customers become active in this app more quickly. How might we achieve that?”
  2. Set a timer for 5 minutes, and instruct everyone to sketch solutions individually (and silently, to help everyone focus).
  3. When the timer goes off, it’s time for each team member to present his or her ideas. Conversation about each idea is important here. Critical feedback will help you see what ideas are best. Every team member should be given the opportunity to share sketches.

If time permits, you can do additional rounds to go deeper into each idea. Working together to solve problems gives everyone shared ownership in the product vision and generates great results because so many diverse perspectives are present.

You might be wondering why everyone’s sketching separately in this exercise instead of together on a whiteboard. According to repeated studies on group brainstorming work, we produce fewer ideas and of lesser quality when we work in groups. Keith Sawyer, a psychologist at Washington University, has summarized the science: “Decades of research have consistently shown that brainstorming groups think of far fewer ideas than the same number of people who work alone and later pool their ideas.”

Remember, early in the creative process we’re best served by covering as much territory as we can instead of going deep on 1 or 2 ideas.

The right tools at the right time

The tools you use to sketch can influence how fast and far your creative explorations proceed. With fine line pens and mechanical pencils, you’ll be prone to create detailed sketches, which are slower. To avoid slipping into detail early on, Jason Fried, co-founder of Basecamp, uses fat markers for sketching on large format graph paper. With fat markers, it’s pretty hard to draw a detailed UI. Instead, you have to focus on the workflow and how people will use your product.

Dave Gray, founder of XPLANE, speaks with Jason Fried of Basecamp about how he explores ideas through sketching.

As ideas are refined, a medium Sharpie or—my favorite—a Staedtler Triplus Fineliner can help you explore your ideas with more precision. Loose paper works best for sketches, as they can be shared, posted on the walls, or mercifully recycled rather than lingering for posterity in your sketchbook. Designers who sketch UI concepts in detail find Copic gray markers add depth and clarity to sketches.

Sketching with remote teams

Team sketching is an important part of the creative process at Lullabot, a creative agency that serves clients like SpaceX, The Grammys, GE, and Martha Stewart. Each new project they take on starts with a sketching session, but not of the sort described above—this design team is entirely remote.

Creative Director Jared Ponchot has devised a simple and inexpensive way to sketch as a team despite the distance that separates them. He bought each designer a simple USB document camera, the IPEVO. At just $60 each, Jared even buys the cameras for engineers, clients, and other key collaborators in the company so they can participate in early sketching sessions.

Like many remote teams, Lullabot runs their meetings via Google Hangouts. In their meetings, they share sketches by simply switching the camera source to the IPEVO. Each team member can walk others through their ideas, or sketch live to explain a new concept.

Ponchot’s solution is simple and effective. It keeps his team focused on a breadth of design solutions early in a project instead of jumping straight to pixels, where they would get lost in execution.

Ideas before execution

Sketching before we jump to the computer has many benefits, the greatest of which is that sketching keeps us laser-focused on ideas instead of the charms of design execution. Design is often described as the act of solving problems for others. We cannot live up to that mandate if polish eclipses exploration in our creative process.

Putting pencils before pixels can help you bring others into the design process and win you allies. Gaining the broad perspectives of your colleagues early on will also help your team produce better design solutions.

Here’s your to-do list to put pencils before pixels into practice

  • Generate dozens of ideas on paper before designing on the computer; sketching is a thought process that will help you discover the unexpected.
  • Get engineers, product managers, and other key stakeholders to sketch with your team in the early phases of a project. This will clarify the project for all, and create a sense of shared ownership.
  • If your team or clients are remote, use USB cams to share sketches and ideate as a team.
  • Constraints like fat markers or time limits on sketching can help you avoid getting lost in detail too soon.

Break the black box

Product design is people

Listen to Chapter

Tom felt lost. After 4 years of tremendous growth, his company was no longer the scrappy startup he’d originally joined. In those early years, Tom simply rolled his chair over to a colleague’s desk when he needed feedback on a design. The work was collaborative, feedback was immediate, his work was known and respected. It was fun! He was able to put on his headphones and devote all of his attention to design.

Then things changed.

The product and company grew—fast. He built out his team, and so did his colleagues. The company moved to a bigger office to accommodate all the new people, and before he knew it, a physical and mental distance developed between his design team and the rest of the company. The designs his team produced weren’t always on the radar, and subsequently, stakeholders no longer understood the value of the team’s work.

Sound familiar? This scenario is common for most growing companies. Design—once transparent, and integrated into the product process—becomes a black box, isolated from engineers and stakeholders, and in the precarious position of being misunderstood or ignored.

When design isn’t visible, it’s no longer powerful.

At a small company, it’s easy to grasp the state of a project by asking a colleague for a peek at their designs. In large companies, spontaneous design conversations rarely happen; design is separated from executives and developers. Designs often remain guarded until a grand reveal brings stakeholders together. By that point, it’s too late for honest feedback—the stakes and repercussions are that much higher because so much energy and emotion have already been invested in what’s likely an off-the-mark design.

This is a dangerous place for product design. It sets the stage for spiked projects and designers searching for more fulfilling work. And of course, designers aren’t the only ones who suffer. Companies that don’t ship their best work run the risk of unrealized potential and less satisfied employees.

But it doesn’t have to be this way.

Connecting design in a large organization

As a company grows, everyone has to work harder—and smarter—at communicating. Designers who succeed in large organizations create social capital by developing a rapport with colleagues across the organization.

You’ll have to get in the habit of stepping away from your computer to create the social capital you need. Grab lunch with a developer who may build out your next design. No need for an agenda—just get to know each other. Spend time with researchers who have their finger on the pulse of your customers, sales people who hear frequent requests, product managers who understand schedules and scope, and customer service agents who know where users struggle the most. All have valuable context to offer you. Each influences the success of your work.

And don’t just network laterally—spend time with different stakeholders and executives to understand their roles and expectations. Ask questions about the broader strategy of the company. You’ll need to understand the big picture to design products that fit into the company vision.

As you become connected to colleagues on other teams, not only will your designs be more informed, you’ll create inroads into your work, putting design on everyone’s radar.

Making design inroads

It’s important to bring stakeholders into the design process early and often to get feedback and fresh perspectives. Sharing your work digitally makes it easy to gather feedback from specific people, but there’s value in setting the stage for unsolicited feedback, too. Surprising things happen when you print screens and post them in a space where passersby can catch a glimpse. Leave Post-it notes and pens nearby and see what happens—I’ve gotten incredible feedback from unexpected sources with this approach.

Unlike digital, print is persistent and casual. It invites spontaneous participation even when you’re not around, which is perhaps its greatest strength.

When design is accessible to all, the process feels inclusive.

Product design is often protected—intentionally or not—from those who are perceived to be outside the process. That’s a shame, because often experts are excluded simply because they don’t move in the same social circles at work. Take note of who leaves useful feedback so you can include them when you share your next digital prototype.

Regularly scheduled design reviews can be a great way to not only keep your design team synced, but to forge connections with other teams. While at the health tech company Counsyl, Laura Martini made a habit of inviting engineers and execs to design reviews to get new perspectives for her team, but also to put design on people’s minds.

Todd Dominey, Director of Design at MailChimp, found sharing digital prototypes crucial to creating inroads to his team’s work, but that face-to-face design reviews go further still to help the company see the big picture.

Making a change

Design teams aren’t the only ones who struggle as a company scales. All teams do. The flat structure and fuzzy roles that once made communication easy in a startup must give way in an enterprise to a well defined org chart and domain experts for the train to stay on the tracks.

Things have to change, and so do we.

You’ll need to be more than a pixel pusher. You’ll have to learn to communicate. Spend less time at your desk and more time talking to colleagues. You’ll need strong relationships to do high impact design work.

The black box that alienates and disempowers design will sneak up on you. Don’t wait for it to take hold of your company. Build inroads into your work now if you want to elevate design and build better products. Here’s your to-do list:

 

  • Share early and often. Set Design Review days on your team’s calendar and invite anyone to participate.
  • Network and build social capital. Your org chart is not a list of names; it’s a group of potential allies. Get to know them.
  • Be open and accessible. Post your work in a public space. Present your work at company coffee hours. Talk about your work and answer questions in a company Slack channel.

Solicit feedback every step of the way. This isn’t design by committee, but good ideas—and constructive criticism—can come from anywhere.
