  • 1. .net technique planning Planning create the perfect prototype Master prototyping and your final site build will be a cakewalk. Odette Colyer of user experience design consultancy Super User Studio explains how to go about it Knowledge needed Prototyping tools, user-centred design techniques Requires Pen and paper; tools such as Visio/OmniGraffle, InDesign, Axure RP Project time Project dependent, but process is flexible It’s much cheaper to change a website early on in the development process than it is to make changes later on. Building prototypes – draft versions of your website – is a good way of nipping problems in the bud and getting things right first time around. At Super User Studio – a user experience design consultancy that offers research, strategy, design and evaluation services to leading online brands – we consider prototyping an essential part of web design. In this tutorial, we’ll walk you through the process from start to finish. The images in this feature are taken from our work with Teachers TV. Over the past year, we’ve worked with the educational site to refine its registration process, introduce new elements to its site and produce the strategy and design for My Viewing Log – a tool that enables you to record how Teachers TV videos impact on your classroom practice. Before you begin the prototyping process, you’ll need to work on Informed decisions Working out the information architecture of a project is a research and strategy for the project. You’ll also need to have worked on the fundamental step in the process of identifying user pathways through a website initial information architecture, to map out the world of the product you’re designing and vital user pathways through that world. There’s a range of UX this by dividing the page into rectangles, then label each area to indicate what tools and techniques to support your preparation for prototyping, but they content or data it represents. The most important purpose of these sketches is won’t all be necessary for every project. The idea is to deploy those that will to get your team thinking about the experience you want the user to have of sufficiently support your understanding of business objectives and user needs, the product. It’s an exercise that can be shared with clients and users too, and and which you deem most appropriate for your project. revisions can be made speedily. At Super User Studio, before we start prototyping we usually give attention Super User Studio often workshops with stakeholders, using paper, scissors, to things like: client brief; business requirements; heuristic evaluation; whiteboards, flip charts, index cards and Post-It notes to produce these early usability testing; user research; audience analysis or personas; competitor prototypes. Some may move straight to interactive prototyping from here. analysis; best of breed review; content/data requirements; features Others will use the sketching exercise as a means of eliminating more obvious requirements; sitemap; user scenarios; task flows; and user journeys. solutions, before digitising the sketches and thinking more deeply about the product’s information space. Techniques For those projects that require independent consideration of information Your end prototype should be a fairly refined and testable representation of design, there’s the process of wireframing. Much like your early sketches, the product. There are several techniques you can use to reach this point, wireframes are page layouts that illustrate the information space of the which again will be project-dependent. For example, if you’re working on a product and depict how that information is presented to a user. Getting fairly simple web application, you may decide to go straight to an interactive started on wireframes involves pulling together your sketches, any workshop prototyping tool such as Axure or iPlotz. With this approach, you’ll consider notes, user research, strategy, content ideas and feedback into a skeletal the information, navigation and interaction design at the same time. However, format. Your first wireframes should be low-fidelity, as it’s important to content-driven websites usually require separate focus on information and gradually build detail into them. In other words, you shouldn’t be too navigation design through the use of wireframes. This enables you to work on concerned about working with specific data or content initially, nor making presenting the information in a way that facilitates user understanding, before them look like the finished product. Instead, your focus will be on considering you think about how the product has to function. what basic features are to be presented on a page, their relative importance Remember, your approach should be prescriptive and you may not tackle or hierarchy and the behaviour of that information in line with user needs. the prototype in a linear way.

As well as being data or content challenges and to consider how your client’s product can an important part of the design process, wireframes have generally become distinguish itself from them. Re-introduce yourself to the key users of the part of the client-facing process too. With this in mind, it’s crucial you keep product too, by reviewing your user research. Reminding yourself of how and documentation well organised. At Super User Studio, we refer back to when an archetypal user might interact with the product, for example, will previous IA diagrams to ensure titling and enumeration is carried through directly influence your interface design decisions. consistently. Sometimes, we’ll use subtle shading and contrast to differentiate There are lots of resources out there to support the development of your key elements of a page to promote understanding of the layout. We also wireframes: try looking up uipatternfactory.com. Alternatively, see how others provide concise annotations, which we’ll look at later. It’s important to ensure approach their wireframes at wireframes.tumblr.com. that your varied mix of stakeholders is communicated with effectively. Ideally, your low-fi wireframes will be reviewed by all key stakeholders, Annotating wireframes including your project team, clients and users. Before you show them to As your wireframes become richer in detail, you’ll feel the need to clients, however, be sure to inform them of the purpose of these greyscale annotate. Annotating your wireframes will ensure your information and navigation design decisions are documented and traceable. They should also You’ll need to absorb feedback communicate these decisions to stakeholders as clearly as possible. Everyone has their own way of annotating. We use number stamps on the wireframe that correspond to notes made in the margin or at the bottom of and not get attached to any the page. We prefer to keep annotations on the same page as the wireframes where possible, to aid readability and quick interpretation. It goes without assumptions you’ve made saying that your notes should be as unambiguous and jargon-free as possible. Just as you put yourself into the mindset of the users when creating the wireframes, it’s the stakeholders’ shoes you need to step into when depictions of their product. They may not be used to viewing wireframes, annotating them. so it’s important to explain that they don’t represent the end layout of the Designers will need to know the varying visual styles required for a product. Instead, their purpose is to encourage discussion, deeper thought component. Developers will need to know the functionality behind that and iteration. At the same time, you’ll need to be prepared to absorb feedback component, where its information is sourced or how that information and not get too attached to any early assumptions you’ve made about layout. behaves. The client will be keeping their eye on how your decisions are Dan Brown has a good take on this in his book Communicating Design (bit. fulfilling business requirements. We often colour-code our annotations to ly/4ipsIx): “Very rarely, if ever, is design work accepted on the first pass, and highlight who they’re most relevant to. Alternatively, you could try splitting up sometimes you can only hope to be ‘wrong in the right direction.” your annotations into different categories. Whatever your approach, keep it as uncomplicated as possible. High fidelity As well as enumerating and titling each wireframe, you may wish to include Once you’ve compiled your feedback and made the necessary amendments to a brief description of the page. This is particularly important when one web your wireframes, you may decide to move on to interactive prototyping.

There’s no need to make annotations on every design decision, though. To move on to high-fidelity wireframes, you’ll need some specific data You’ll only end up diminishing the efficacy of the wireframes if you over- or content in place.

Inevitably At Super User Studio, we use Axure, as it can handle quite complex there will be differences of opinion, but by keeping primary users and their interactions such as mimicking Ajax functionality.
