AACE DRMP key terms

A structured method for evaluating choices under uncertainty by identifying alternatives, possible outcomes, probabilities, and consequences so that decision makers can compare options consistently and transparently.

A graphical model that maps sequential decisions, chance events, and outcomes as branches, with probabilities and values at terminal nodes, enabling comparison of expected monetary values across alternative courses of action.

The probability-weighted average of possible financial outcomes for a decision or risk event, calculated by multiplying each outcome value by its probability and summing the products.

A family of techniques for ranking alternatives against several conflicting criteria by assigning weights and scores, then combining them into an overall preference score that supports transparent trade-off decisions.

A structured decision technique that decomposes a problem into criteria and alternatives, uses pairwise comparisons to derive relative weights, and checks consistency of judgments before ranking options.

A decision tool that rates each alternative on multiple criteria, multiplies each rating by a criterion weight, and sums the results to produce a comparable total score.

A technique for testing how changes in one or more input assumptions affect a model's output, revealing which variables most influence the decision or risk exposure.

A horizontal bar chart that ranks uncertain variables by the size of their effect on a result, with the largest swing at the top, helping analysts focus on the most influential assumptions.

An economic evaluation that compares alternatives by summing all relevant costs over the asset or project life, including acquisition, operation, maintenance, and disposal, usually discounted to present value.

A structured, function-focused review that seeks to improve value by removing unnecessary cost while preserving or enhancing required performance, often applied at design or decision gate.

A financial indicator calculated by dividing the present value of benefits by the present value of costs; a ratio above one suggests benefits exceed costs.

The sum of discounted future cash flows minus the initial investment, using a specified discount rate; a positive NPV indicates the option adds value.

The discount rate at which a project's net present value equals zero, often compared with a hurdle rate to judge whether an investment is financially acceptable.

The way a decision problem is defined, including scope, objectives, alternatives, constraints, and time horizon; framing shapes which options and risks are considered.

A systematic tendency in judgment that can distort estimates and choices, such as anchoring, overconfidence, or confirmation bias, requiring deliberate debiasing techniques in decision processes.

The process of identifying and comparing feasible courses of action against agreed criteria to determine which option best satisfies objectives within constraints.

A structured comparison of competing objectives or design choices that makes explicit what is gained and lost when selecting one alternative over another.

A document that defines how risk management will be performed, including methodology, roles, budget, timing, risk categories, appetite, reporting, and review cadence for a project or organization.

A living record of identified risks and opportunities, usually capturing description, cause, potential effect, probability, impact, score, owner, response, and status for monitoring.

A hierarchical grouping of risk sources or categories, such as technical, external, organizational, and project management, used to organize identification and ensure balanced coverage.

The iterative process of finding, documenting, and classifying uncertainty that could affect objectives, using techniques such as brainstorming, interviews, checklists, and assumption analysis.

The amount and type of risk an organization is willing to pursue or retain in pursuit of its objectives, expressed qualitatively and sometimes quantitatively in risk criteria.

The acceptable variation in performance or exposure around an objective that an organization or stakeholder can bear, often expressed as measurable limits for specific risk categories.

A defined limit or trigger point beyond which risk exposure is unacceptable and action must be taken, escalated, or the activity stopped.

A subjective assessment of probability and impact using descriptive scales or matrices to prioritize risks for further analysis or response, without detailed numerical modeling.

A numerical evaluation of risk effects on objectives using techniques such as Monte Carlo simulation, decision trees, or sensitivity analysis to estimate possible outcomes and required reserves.

A grid that plots risks by likelihood and consequence, often with risk scores or color zones, to rank exposures and guide prioritization and response planning.

A computational technique that repeatedly samples probability distributions for uncertain inputs to produce a range of possible outcomes and confidence levels for cost or schedule.

An amount of time or money set aside for known risks and uncertainties with identified responses, included in the performance measurement baseline and controlled by the project manager.

A budget or time allowance held by senior management for unforeseen work within the project scope but outside the performance measurement baseline, released through formal change control.

The process of choosing and documenting actions to address risks and opportunities, including avoidance, mitigation, transfer, acceptance, exploitation, sharing, and enhancement, with owners and triggers.

A response strategy that eliminates the threat or its cause entirely, often by changing scope, requirements, or approach, thereby removing exposure rather than reducing it.

A response strategy that reduces the probability or impact of a threat, or both, through actions such as design changes, testing, controls, or contingency planning.

A response strategy that shifts financial or operational consequence of a threat to a third party, such as through insurance, contracts, warranties, or outsourcing, without eliminating the underlying risk.

A response strategy in which an organization acknowledges a risk and chooses to retain it, either actively with a contingency plan or passively without further action, within its tolerance.

A named individual or role accountable for monitoring a specific risk, implementing its response, and escalating changes in exposure to the appropriate level.

The process of raising a risk to a higher authority when it exceeds defined tolerances, requires resources beyond the current level, or cannot be managed locally.

The remaining exposure after planned responses have been implemented and their effectiveness considered, which must be monitored and accepted within tolerance.

A structured expert elicitation method using anonymous, iterative questionnaires and controlled feedback to converge on estimates or judgments while reducing group pressure and bias.

A technique that examines project assumptions for validity, instability, and consequence if false, converting uncertain assumptions into risks or information-gathering actions.
