What is PIE?
Principles for Interfaces and Experiences (PIE) is Just Eat Takeaway’s global design system.
A design system is like a recipe for creating visually appealing and user-friendly products. Just as a recipe uses ingredients and instructions to help you make a delicious meal, a design system uses components, patterns and documentation to help us design amazing apps and websites.
For example, just as a recipe details the specific amounts of ingredients and cooking time needed, a design system details the font sizes, colour palettes and layout rules to ensure consistency and usability across all JET products.
In both cases, following the recipe makes it easy to produce consistently great results that can be replicated time and time again.
Here are six reasons why you should use PIE for your products:
PIE is both a service and a product. We create and maintain its contents and guidelines, and also support other teams through business area libraries.
Our goal isn't to take ownership of design from designers. We're here to support you and ensure all JET's products align to the system, providing scalability, consistency and high levels of craft.
