  8. … JIRA • jira.alma.cl: • JIRA 4.4 • > 130 projects, 40 issue-types, >1350 users, … • several system-wide settings not optimal for ICT (e.g. resolution, priority, time tracking, issue statuses, …) • New server: • JIRA 5.2.9 • 9 issue types, with clear definition • specific workflow for typical ICT software development process ICT planning meeting #1 / SCO
