Science is in the process and tools
Art is in the people and their relationships
Management Systems without tools provide partial solutions. Success means delivering what those paying for the project set out to accomplish. In the presence of uncertainty, risk management is a critical success factor.
Before risks turn into issues, the uncertainties that create the risk must be handled. To handle reducible uncertainties (Epistemic) - creating reducible risk - estimates must be made for the probability of occurrence and probability of impact, and the probability of the corrective or preventive actions of a reducible risk, and the probability of the residual risk.
For irreducible uncertainties (Aleatory) - creating irreducible risk - estimates of the statistical processes of the naturally occurring uncertainties must be made. These estimates are used to model the statistical processes and assess the needed margin to protect the cost, schedule, and technical performance from the impacts.
