Storm System Risk Based Prioritization & Decision-Making: Asset risks are well understood and documented based on evidence of the

probability and the consequence of failure. Decisions made about assets and service

delivery are informed with appropriate and timely information, are transparent, and

are aligned with community priorities and long-term reliable service delivery.

Storm System Staffing: Staff have the necessary time,

knowledge, skills, and capacities to achieve asset

management outcomes and are implementing asset

management as part of their jobs. Roles are clearly

understood by everyone, including leadership, and all

Storm System Leadership: There is no perception of siloes across

departments at all levels of the organization. There is a strong culture of

teamwork and information is readily and consistently shared through formal

and informal channels. Staff and elected officials understand the need for

management of storm system infrastructure and support its implementation,

are effective leaders, have a culture of inter-disciplinary teamwork, value

informed decision making, and continuously develop their skills, experience

and capacity.
