What is the difference between a hazard and an obstacle in the context of uncertainty?

In the context of uncertainty, hazards and obstacles describe different concepts:

Hazard:

A cause or source of potential harm or adverse impact.

Example: A poorly maintained system poses a hazard for downtime.

Obstacle:

An event or condition that negatively affects the achievement of objectives.

Example: System downtime becomes an obstacle to completing a project on time.

Key Difference:

Hazards are potential causes, while obstacles are actual events or conditions that create challenges.

Why Other Options Are Incorrect:

A: Obstacles are events, not conditions that create hazards.

B: Hazards relate to causes, not likelihood.

D: Hazards and obstacles are distinct concepts, not types of each other.
