Who should be involved in the design and development of risk management and contingency plans for a project?

The stakeholders (anyone who has an invested interest in the project at hand) should be included to raise potential threats or hazards and allow for the project manager to establish contingency plans in the planning phase.

Good communication and planning can create effective contingency plans via holding a meeting with key stakeholders. Thus, when a calculated risk occurs the contingency plan is ready to implement immediately.

If a crisis were to occur from unforeseen threats or risks such as a force of Mother Nature, then this would be dealt with by a crisis management team collated from select managers of project operations and the project manager. Crisis management slightly differs from risk management and has its own set of contingency planning stages (to be incorporated into a project manager's plans).
