Introduction to
Design Systems
What is a Design System?
Let's start by defining "system"
What is a System?
"A system is an interconnected set of elements that is coherently organized in a way that achieves something."
- Donella H. Meadows
Thinking in Systems: A Primer
Systems are composed of:
• Elements
• Interconnections
• Function or Purpose
What is a System?
• Football Team
- Elements: players, coaches, field, the ball, etc
- Interconnections: rules of the game
- Purpose: win games, have fun, etc.
• School
- Elements: teachers, students, books, etc
- Interconnections: admissions, exams, grades, etc
- Purpose: education

Should We Have One?
Many of the companies listed with our examples are far larger and have a lot more resources to support a design system
Some questions to consider:
• Will our current processes and structure scale for our needs?
• Could our UI be more easily maintained and updated?
• Are we able to test new ideas as quickly as they would like?
A Fair Question
Should We Have One?
As frontend and design tooling has improved, design systems have become more accessible for small-to-medium-sized companies.
Perhaps it makes sense to start by building tools to support immediate problems and build from there.
