Within Incident Management there are Task Boards which contain lists of tasks that get completed through a workflow. You can add as many task lists and tasks to a task board as you need. Behind each task (row) there is a form which can be configured in the Admin Area.
Ideas for your Task Boards:
Initial Response Tasklist
Task Board Templates
Each task board has a Template which outlines the layout of the form behind each task, and which columns should display on the list view of tasks.
Collections are used to pre-load data into a task board. For example you might have a task board of 'Checklists' and you could enter all the initial response tasks into the collections in advance. They are then available pre-loaded to be available to import during an actual incident.
