This document presents design principles for software as a service (SaaS) created by the UX team at JDA Labs. It identifies seven principles: make it clear, keep it smart, bring trust, tell a story, pioneer design ideas, stay current and stay elegant. Each principle is explained with examples of why it is important and how it can guide product design decisions for SaaS applications. The principles are intended to serve as building blocks for user experience design when developing SaaS products and services.
