Dual-test operator assessment

A computer system, comprising:

• a processor;
• a computer readable memory in circuit communication with the processor;
• and
• a computer readable storage medium in circuit communication with the processor;
• wherein the processor executes program instructions stored on the computer-readable storage medium via the computer readable memory and thereby:
• in response to determining that performance data of operation of a device by an operating user meets a safety requirement, determines a degree of deviation of a value of the performance data from a baseline pattern of good performance values defined for the user;
• in response to determining that the degree of deviation of the operating data value meets a cognitive assessment threshold, administers a cognitive aptitude test to the user that comprises a cognitive test challenge that is selected from baseline aptitude profile data that comprises challenges previously responded to by the user;
• and
• in response to determining that a degree of deviation of a value of a response provided by the user to the cognitive test challenge from a performance metric value of the baseline aptitude profile data meets a threshold cognitive assessment threshold, executes a corrective action that reduces a risk of loss from impaired cognitive performance in the operation of the device by the user.

A computer program product, comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising instructions for execution by a processor that cause the processor to:
• in response to determining that performance data of operation of a device by an operating user meets a safety requirement, determine a degree of deviation of a value of the performance data from a baseline pattern of good performance values defined for the user;
• in response to determining that the degree of deviation of the operating data value meets a cognitive assessment threshold, administer a cognitive aptitude test to the user that comprises a cognitive test challenge that is selected from baseline aptitude profile data that comprises challenges previously responded to by the user;
• and
• in response to determining that a degree of deviation of a value of a response provided by the user to the cognitive test challenge from a performance metric value of the baseline aptitude profile data meets a threshold cognitive assessment threshold, execute a corrective action that reduces a risk of loss from impaired cognitive performance in the operation of the device by the user.
