This document provides 10 tips for growing usage of JIRA from 5 users to 800 users based on the experience of Verisign. Some of the key tips include: 1. Set manageable milestones and start small when implementing JIRA instead of trying to achieve everything at once. 2. Create a steering committee of users to help determine what changes to make and when. 3. Conduct user surveys to understand how people are using the tool and identify areas for improvement. 4. Empower users by using plugins to add functionality without changing code. 5. Standardize workflows, naming conventions, and other aspects to simplify usage and maintenance.
