A [software SDK](https://developer.yahoo.com/social/sdk/) is a set of tools that allows the creation of applications for certain software, or video games, or a hardware platform. A hit could be as simple as a bunch of APIs or [software that talks](https://developer.paypal.com/webapps/developer/docs/integration/mobile/mobile-sdk-overview/) to embedded or proprietary systems. An SDK is a collection of tools to make something with. It’s a leg-up for development. And they’re needed for design, too.
Guide me, don’t tell me
When working with identity guidelines, pattern libraries, or styleguides, the biggest pushback I hear from designers is ‘I don’t want to be this specific. Point me in the right direction, but don’t be prescriptive’. The chances of a pattern library or styleguide answering every design problem that comes along is slim, but providing an overall understanding of a system is probably the best position you can put a designer in in order for them to do good work. That, and providing them with the right tools.
Giving someone a design SDK may be better than asking people to look for, navigate and understand an entire website dedicated to your design language.
For example, let’s say you work for a large bank in their in-house design team. Your design language is years old and grown organically to become a place of internal collaboration for stakeholders and silos – not really the place for external suppliers. One day, you need to get a very small web project designed and your team is maxed out so you outsource it to a freelancer. Now you’re faced with a problem.
Your design language documentation and collaboration site is housed internally, behind the company firewall, and you can’t give her access. You try to collect some material together for her, but it takes all morning before you even have an idea of what might be needed. And then you can’t find the logo in the right format. All you really need to do is send her what is needed and nothing more.
All of this takes too much time. And a styleguide doesn’t solve the problem. A design SDK is what you need.
A style guide is about providing the right help for every use case all in one place. An SDK is about providing the right help for a specific environment. In software development, APIs may have middleware wrappers like a PHP and Ruby. But regardless of the wrappers, the endpoint is always the same: the software at the end of the API. In the same way, a Design SDK should provide an end-point — a design language — typically via different methods such as HTML and CSS, or Sketch files, or Photoshop files, or text documents, or InDesign swatches.
The key to this is to be where the designer is. Learn where your designers and design partners do their work and provide tools that help get your design language adopted in those tools.
The problem with style guides
Style guides can be great for documenting a design system and providing a way for design to be consistent across multiple projects, products and people. But they can also be a shackle for creativity. A firehose of difficult to navigate content that compromises clarity for brevity. The key thing with style guides is they rely on you going hunting for what you need. They are everything for everybody. They are pull rather than push.
A design SDK I’m talking about is push rather than pull. It’s given to you, and it contains just what you need and nothing more.
What would be in a design SDK?
The key here is to provide just enough for someone to get going with their work. For some projects, this may be all of the following, but for others, it could just be a couple.
- Moodboards and inspiration
- HTML boilerplate
- CSS or Sass snippets
- Template assets
- Suitable example images
- Icons in various formats
- Licensed typefaces or links to the correct typefaces
- Branding identity guidelines
It would be ideal for me if an SDK could be created on the fly for different people based on project needs. So, for example, for freelancer ‘A’, I don’t want to send them HTML or CSS as I know they’re not building anything, so I just send them mood boards and inspiration, image assets and branding guidelines. For freelancer ‘b’, a front-end developer, I send boilerplate, CSS, template assets and icons. I mix and match and provide the design SDK, rather than send along a URL and expect them to know what they need and how to use them.
‘Isn’t this just for big, in-house teams and projects?’
No, I don’t think it is. There were plenty of times when I ran my design agency that we could use a design SDK as a deliverable for a client. Because, after you have finished working with them, chances are they will need other people to take forward your design in one way or another. And maybe the client isn’t the best person to determine what is needed to do that. A design SDK would be a great deliverable to ensure design integrity is maintained after you move onto other projects.
