Risk management
How much risk leadership is willing to live with to reach the company's goals.
Formal
A leadership decision stating the amount and type of risk an organisation will accept, used as the line that decides whether a risk needs further treatment.
In plain English
Like how fast you are willing to drive - some people accept more danger to arrive sooner, others do not.
In practice
A pension fund's board writes down that it accepts no risk of losing members' data, but will live with short outages of the internal chat, and the IT security manager plans controls to match.
Why it matters
Without a stated limit, every risk decision becomes a matter of opinion, and leadership cannot be held to account.
