High-level and low-level tasks in Kanban

We use Kanban to coordinate our projects and tasks.

Our field of work is IT operations and we're generally […]

Separating data from code in Puppet modules is advisable as it improves reusability of code. The separation can be accomplished with Hiera by having separate levels based on facts, organizational units, locations, etc. Hiera can also be used for storing private data that needs to be protected and must not be readable by outsiders.
