There can by no means be an exhaustive checklist of prototyping strategies, since there’s fairly actually an limitless variety of methods you possibly can construct prototypes. What we will do, nevertheless, is present a helpful checklist of the eight commonest prototyping strategies, along with finest observe suggestions that provide help to maximise your prototyping and testing periods. By arming your self with these eight widespread strategies, you possibly can start your iterative strategy of constructing prototypes to be able to empathise together with your customers, to determine on and refine your concepts and to check your options.
Earlier than we start wanting on the widespread prototyping strategies, allow us to first briefly look at the prototyping and testing course of. You will have to concentrate to those 4 key elements of prototyping and testing, it doesn’t matter what methodology you select to utilise:
- Individuals – together with these whom you might be testing and the observers
- Objects – static and interactive, together with the prototype and different objects the folks and/or prototype work together/s with
- Location – locations and environments
- Interactions – digital or bodily, between folks, objects and the location
If you end up constructing your prototypes, in addition to once you’re testing them, take note these key elements. As an illustration, if you’re testing your prototype in a lab, take into consideration the way to simulate the pure setting through which your design will have interaction its customers. Additionally, be aware of different objects that the prototype can be used with. When performing a activity, for instance, will the customers be sporting gloves, or have their arms full? What implications would which have on how they’ll use a services or products? With these 4 elements of testing a prototype in thoughts, allow us to take a look at the eight widespread strategies of prototyping that you should utilize.
Sketches and Diagrams
Sketching is without doubt one of the earliest types of prototyping you should utilize. It requires little or no effort and doesn’t essentially depend on creative ranges of drawing ability to show helpful, and therein lies its worth. Use sketches for instance your concepts and launch them into the actual world — even the only and crudest of sketches can simply obtain that. Sketch easy illustrations of your ideas in order that they don’t exist solely in your thoughts, therefore permitting you to share these together with your team-mates for additional dialogue and ideation.

Even the messiest of scrawls (not that what we see above is a messy scrawl) can function nurturing “soil” to make the seed of an thought sprout right into a first-class finish product.
You may also sketch diagrams and thoughts maps to be able to illustrate a system, course of, or the construction of your concepts. You’ll be able to sketch the assorted contact factors that have an effect on a person’s journey, and then determine how they relate to at least one one other. Alternatively, you possibly can visualise and analyse how your concepts can relate to at least one one other and complement (or typically compete with) each other. Diagramming is a helpful method to perceive complicated conditions or use circumstances, the place many elements and gamers have an effect on each other. Journey maps, behaviour maps, system movement diagrams, and a variety of different mapping strategies are at your service that can assist you scope out complicated conditions.
Sketching is a helpful methodology of prototyping as a result of you are able to do it virtually in all places, with a paper and pen, and even in your smartphone or pill.

You don’t must be an artist to sketch for an efficient end result. The great thing about sketching is which you could get the concept down just about as quickly because it hits you with out worrying about it vanishing — even when you must lean awkwardly to scribble one thing whereas standing up on a prepare, it’s an amazing begin.
Digital merchandise like cell apps, web sites, and internet companies, in addition to different screen-based merchandise or experiences usually require you to create a variety of prototyping strategies within the run as much as the ultimate design and improvement. Paper interfaces are useful on the early levels of prototyping for digital merchandise. You’ll be able to create paper interfaces by sketching them out, or by drawing and slicing out usable elements of a person interface (akin to a textual content subject or a dropdown menu, and so forth.).
Jakob Nielsen, co-founder of the Nielsen Norman Group, explains that paper prototypes are extraordinarily simple and low cost to provide, whereas they’ll give you many insights that may provide help to get monetary savings. When designing digital merchandise, you could be tempted to create higher-fidelity prototypes straight on a pc, or begin creating the product immediately. Whenever you use paper interfaces, nevertheless, you possibly can uncover many areas for enchancment, akin to usability points, that may provide help to make enhancements to your design within the early levels, thus avoiding manufacturing prices. Based on Nielsen, usability research present that early-stage adjustments are about 100 instances cheaper than adjustments made in later levels of a product improvement course of. Because the outdated proverb goes:
“A sew in time saves 9.”
A generally used course of in creating paper interfaces is sketching and assembling prototypes of a working digital system. We do that through the use of separate sheets of paper, together with moveable interface components, scrolling items of paper, and different interactive options.
Telling tales is a superb method of guiding folks by way of a person expertise. Storyboarding, a way derived from the movie business, is one thing you should utilize for early prototyping to permit your self to visualise the person’s journey or how customers would expertise an issue or product. Whenever you draw storyboards, attempt to think about the full person expertise, and then seize it in a collection of pictures or sketches.
In Storytelling for Person Expertise: Crafting Tales for Higher Design, Whitney Quesenbery, co-director of Heart for Civic Design, and English author Kevin Brooks clarify the advantages of utilizing tales in design initiatives. Based on them, tales not solely allow us to collate info on customers, duties, and objectives but additionally spark new concepts by encouraging discussions and collaboration between ourselves and different designers. By drawing out a person’s expertise, we additionally higher perceive their world and are thus capable of suppose of their footwear.
Storyboarding, as a prototyping methodology, ensures that we all know our customers properly sufficient (it might be arduous to sketch a storyboard in any other case) and permits us to remember the context of the answer we’re designing. It’s helpful for growing an empathic understanding of customers — and for producing high-level ideation and discussions. Storyboards, nevertheless, are not very helpful for fine-tuning the particulars of merchandise, as a result of the drawings are usually extra macroscopic in nature.

Lego’s genius transcends little one’s play — now we have a lot to faucet from Lego as regards prototyping.
Lego is a staple of any child’s toy field. Its versatility and potential to spark creativeness is what drives the corporate’s success. As a designer, you possibly can benefit from Lego’s ubiquity and versatility to create fast and easy prototypes of your concepts. One of the best a part of utilizing Lego to construct your prototypes is that they change into simple to dismantle and tweak; merely detach part of your Lego prototype, swap it with an alternate design, and play with it to see if it really works.
As Tim Brown, CEO of worldwide design agency IDEO, recounts in his e book Change by Design, Lego prototyping has been extensively utilized in IDEO’s design considering course of, together with as soon as the place it was used to create a prototype for a posh insulin injection system.
In actual fact, Lego has taken its toy’s potential to stimulate creativity and ideation significantly. In collaboration with Johan Roos and Bart Victor, professors on the Worldwide Institute for Administration Improvement in Switzerland, it launched Lego Severe Play, a strategy that goals to foster artistic considering and downside fixing in companies.
Nonetheless, for the needs of prototyping, any Lego ought to suffice. You need to use Lego bricks to create tough prototypes of merchandise… or use Lego characters to simulate a person’s journey. This permits your crew to dive straight into establishing your eventualities and telling tales.
Position-Taking part in
Position-playing, or experiential prototyping, is a technique that permits your design crew to discover eventualities inside the system you might be focusing on bodily. We will make one of the best use of role-playing in capturing and expressing the customers’ emotional expertise of utilizing a services or products. You may also use it to realize an empathic understanding of your customers — by way of simulating what they’re experiencing. By re-enacting scenes and conditions you are trying to enhance, your crew can get a greater sense of what the expertise may very well really feel like and the place you should focus your predominant give attention to enchancment. You may also keep in mind the expertise extra vividly once you bodily expertise it, fairly than draw it out in a storyboard, as an illustration.
We will use role-playing with various ranges of element, however one of the best expertise occurs once you simulate the bodily setting of the person. You’ll be able to create props, use objects round your office (akin to chairs and desks), and use audio simulations by enjoying a soundtrack that mimics the person’s setting. In case you are the facilitator of the role-playing train, assign every participant a task, and choreograph sure skits relying on the aim of the role-playing train. As an illustration, if you’re making an attempt to really feel the emotional expertise of utilizing your service resolution, your crew can act out the elements of a person and a service supplier.
Determine on roles, scenes and storylines beforehand, and probably mix this methodology with storyboarding to be able to seize the scenes and the teachings you’ll be taught from every scene.

When the top result’s a bodily product, you should utilize a variety of supplies to construct mock-ups for testing. You need to use tough supplies, akin to paper, cardboard, clay, or foam, and you can too repurpose present objects you discover round you to be able to construct bodily fashions.
The aim of a bodily mannequin is to deliver an intangible thought, or two-dimensional sketch, right into a bodily, three-dimensional airplane. This permits for significantly better testing with customers, and it might spark discussions concerning the kind issue of the answer.
Wizard of OuncesPrototypes

Wizard of Ouncesprototypes are prototypes with faked features — as an illustration, interactivity that comes from a human fairly than an algorithm or software program code, with customers believing the latter is the case — that you should utilize to check together with your customers. Just like the wizard of Ounceswithin the story (who generates an ominous, magical and misleading look from behind a curtain), you might be mimicking some elements of your product for the sake of prototyping it, permitting you to avoid wasting time and assets. The most typical instance of Wizard of Ouncesprototypes is a prototype of a digital system, the place the person is “tricked” into considering the system responses are computer-driven, when they’re really human-controlled — akin to a bit of digital assistant software program through which a human, engaged on one other pc, varieties the responses. Notice—ethically, we as designers are properly inside the boundaries when doing this; it doesn’t contain manipulating customers for immoral achieve.
In order to create a Wizard of Ouncesprototype, you first should determine on what you wish to take a look at or discover. Then, determine a method of mimicking or faking the interactions. This requires a good bit of ingenuity, however you should utilize ready-made instruments akin to social media, PowerPoint, immediate messaging and movies to create a practical imitation of pc interactivity. As an illustration, you possibly can create an interactive PowerPoint presentation and use it along with messages despatched to a pc to be able to faux the interactions of a social media website with out having to code.
You might be finest off utilizing the Wizard of Ouncesprototyping methodology when testing interactions of your product earlier than constructing it. Nonetheless, as you could have seen, this prototyping methodology entails a good period of time and effort. Due to this fact, you possibly can actually solely make one of the best use of it for testing the results and interactions of complicated programs or within the later levels of your design mission.
A user-driven prototype is not like some other prototyping methodology beforehand talked about. As a substitute of constructing a prototype to check on customers, you’ll as an alternative get the person to create one thing, and from the method be taught extra concerning the person. Whenever you ask the person to design an answer, fairly than present suggestions on a prototype, you possibly can be taught concerning the assumptions and wishes that the person possesses. The aim of a user-driven prototype is to not use the options that the customers have generated; as an alternative, it’s to make use of their designs to know their considering. You need to use user-driven prototypes to realize empathy together with your customers or to fine-tune the small print of your product upon getting an thought in thoughts.
With the intention to create a user-driven prototype, it’s best to ask the customers to create one thing that allows you to perceive how they give thought to sure points. As an illustration, if you’re inquisitive about creating an improved airport ready expertise, you possibly can ask customers to attract out what they suppose is the perfect airport ready course of — or you possibly can give them a bunch of Lego bricks and encourage them to point out you their dream ready space in an airport. Alternatively, in case your resolution is a website, you possibly can ask your customers to create a sketch of what options they suppose the website ought to have. For user-driven prototypes to be helpful, it’s best to steadiness the quantity of provide help to supply the customers so they don’t really feel misplaced (and thus fail to ideate), whereas making the session open sufficient so as to be taught extra concerning the customers with out shepherding them in direction of your personal concepts, which might defeat the aim on this mild.
Which Prototype Ought to I Construct?
With such a variety of prototypes you possibly can construct, it is perhaps somewhat overwhelming at instances once you and your crew should determine on what precisely to construct. Fortunately, IDEO’s Design Equipment provides a easy, four-step course of which you could comply with to be able to provide help to determine what sort of prototypes to make use of.
What’s your thought about?
Together with your crew, be aware down the important thing elements of your thought or concepts. Determine what must be examined, and ask a key query for every element of your thought that you simply want to take a look at.
Which questions do you wish to ask?
Select a number of questions you need answered. As an illustration, if you wish to take a look at out whether or not the burden of your product is appropriate and usable, think about constructing a tough prototype with the identical weight as that of the ultimate product. Then again, if you wish to take a look at the extent of interplay between the product and the person, you could wish to use role-playing as an alternative.
What prototype is sensible?
For every query, take into consideration the type of prototype that makes probably the most sense and that will most successfully reply the query. If doable, maintain a brainstorming session together with your crew so as to generate as many options as doable, then slender down the alternatives by way of dialogue.
Simply do it!
Design Considering has a bias in direction of motion. Which means you shouldn’t spend an excessive amount of time deliberating on what to construct, and the way to construct it — simply go on the market and begin testing! In case you are unsure about what sort of prototype to make use of, make a number of and take a look at them. Your first few prototypes could also be failures, however they’ll inform you a lot extra than simply serious about what to do would inform you.
The Take Away
When prototyping, take note of 4 key issues: folks, objects, location, and interactions. These elements will have an effect on how your prototype will work — and what to watch in testing periods. With these elements in thoughts, you possibly can construct prototypes based mostly on any of the eight strategies we’ve simply coated: sketches, paper interfaces, storyboards, Lego prototypes, role-playing, bodily fashions, Wizard of Ouncesprototypes, and user-driven prototypes. Lastly, if you’re not sure of what prototype to construct, you should utilize IDEO’s four-step course of that can assist you to start out making prototypes. The vary of selections is vast and clear sufficient so that you can latch — sooner fairly than later — with the precise prototype for you and therefore take a big step in direction of in the end realising your concepts within the type of a serviceable, user-friendly design.
