Who decides, who does it, who is asked first and who is told after, activity by activity.
Builds the responsibility matrix of any process or project of any company, from hiring and customer orders to month-end closing and IT incidents: one row per concrete activity with what it produces, one column per role, in plain words, one role deciding each activity. Describe your situation, or list your own activities: they are kept as you wrote them.
Your real situation
A tender, a new site, a data breach, month-end closing: the activities come from your facts.
Readable by everyone
Plain words in every cell, one role deciding each activity, what each activity produces.
What to settle
An activity nobody decides, or one role carrying almost everything, is pointed out.
