Jens Rasmussen was a very influential researcher in human factors and safety systems.

### Contributions

#### Skill-rule-knowledge (SKR) model

TBD

#### Boundary of acceptable performance

Rasmussen proposed a state-based model of a socio-technical system as a system
that moves within a region of a state space. The region is surrounded by
different boundaries:

* economic failure
* unacceptable work load
* functionality acceptable performance

![Migration to the boundary](boundary.png)

Incentives push the system towards the boundary of acceptable performance:
accidents happen when the boundary is exceeded.

### Contributions

Woods seems to have contributed an enormous number of concepts.

#### The adaptive universe

TBD

#### Theory of graceful extensibility

From [The theory of graceful extensibility: basic rules that govern adaptive systems]

1. Boundaries are universal
2. Surprise occurs, continuously
3. Risk of saturation is monitored and regulated
4. Synchronization across multiple units of adaptive behavior in a network is necessary
5. Risk of saturation can be shared
6. Pressure changes what is sacrificed when
7. Pressure for optimality undermines graceful extensibility
8. All adaptive units are local
9. Perspective contrast overcomes bounds
10. Reflective systems continually risk mis-calibration

### Concepts
