## 一言でいうと

Risk is the effect of uncertainty on an objective. It can involve downside, upside, or both, and becomes decision-ready only when the objective, uncertain event or condition, likelihood, consequence, owner, response, and remaining exposure are explicit.

## 計算の考え方

Risk has no universal formula. A common assessment combines likelihood and consequence under a defined method; expected-value models may multiply probability by financial impact when both inputs are defensible. Qualitative or ordinal scores must not be presented as precise probabilities or money. Likelihood | Estimated chance or frequency of the uncertain event under stated assumptions and controls Consequence | Possible effect on the objective, including magnitude, timing, duration, and affected stakeholders Risk level | Combined likelihood and consequence under a defined method | Reassess residual risk after responses or context changes

- Likelihood | Estimated chance or frequency of the uncertain event under stated assumptions and controls
- Consequence | Possible effect on the objective, including magnitude, timing, duration, and affected stakeholders
- Risk level | Combined likelihood and consequence under a defined method | Reassess residual risk after responses or context changes

## 含めるもの / 含めないもの

Keep the generic concept distinct from a domain-specific risk model and from an issue that has already occurred. Include | Uncertainty that could affect a stated business, financial, project, operational, safety, legal, or security objective Exclude | Routine work with no material uncertainty and realized issues that require present-tense response rather than future-risk treatment Track explicitly | Objective, scope, causes, event or condition, likelihood, consequences, assumptions, owner, response, indicators, and residual risk

## 意味

Risk concerns uncertainty that can affect an objective. In practice, teams identify the objective, describe the uncertain event or condition and its causes, assess possible consequences and likelihood, select a response, assign an owner, and monitor residual risk. Some methods focus on downside exposure, while planning may examine both threats and opportunities, so the adopted definition and scale must be explicit. Financial, project, operational, safety, legal, and information security risks do not share one universal scale.

## 役立つ場面

Prioritizes whether to avoid, reduce, share or transfer, accept, or deliberately pursue an opportunity-related risk. Assigns accountability, decision authority, response deadlines, and escalation thresholds before exposure becomes an issue. Makes trade-offs among objective value, response cost, operational constraints, opportunity, and residual risk explicit.

## 使い方のポイント

- Risk must be tied to an objective; a vague concern without a decision context is not yet decision-ready.
- Use a method and scale appropriate to the domain, and record assumptions and evidence.
- A realized event becomes an issue or incident, while related future uncertainty can remain a risk.
- A risk response needs an accountable owner, selected action, acceptance criteria, indicators, and review cadence.
- Monitor changes to context, assumptions, controls, and objectives, then reassess residual risk.

## 何が数字を動かすか

Risk changes when objectives, assumptions, external conditions, dependencies, exposure, controls, or the quality and freshness of evidence change. Market, regulatory, technical, financial, operational, and human changes can alter likelihood or consequences. Dependencies, concentration, weak controls, and limited response capacity can increase exposure. Consequences depend on the objective, affected stakeholders, timing, duration, and reversibility. Responses can change likelihood or consequences, but assumptions, side effects, and control failure can leave residual risk.

## 判断するときの注意点

Do not let a heat map, a single score, or a quiet history create false confidence. Define scales and assessment scope before scoring; do not compare unlike contexts as if their units matched. Record assumptions, uncertainty, and evidence quality; missing data is not evidence of low risk. Move realized events into issue or incident handling without deleting unresolved, secondary, or downstream risk.

## よくある誤解 / 落とし穴

- Risk always means a confirmed negative event. Risk addresses uncertainty, and planning may examine opportunities as well as threats.
- A high score proves an event will occur. It expresses an estimate under a defined method, assumptions, and evidence set.
- Controls or a quiet history eliminate risk. Changed conditions, failed assumptions, weak controls, and unobserved exposure can leave residual risk.

## 最小例

A company plans a product launch to reach a revenue objective. A critical supplier has uncertain delivery capacity, so the team records the delayed-launch scenario, causes, likelihood range, financial and customer consequences, assumptions, and owner. It qualifies a second supplier and sets an escalation date. When the original supplier misses a confirmed milestone, that missed delivery becomes an issue; uncertainty about later deliveries and launch impact remains residual risk.

## FAQ

### What is the shortest useful risk statement?

State the objective, uncertain event or condition, cause, and possible consequence.

### When does a risk become an issue?

When the uncertain condition or event has occurred and requires present-tense action. Related future uncertainty can remain as residual risk.

### Must every risk be eliminated?

No. An organization can avoid, reduce, share or transfer, accept, or pursue risk according to objectives, obligations, and risk criteria while monitoring what remains.
