ABSTRACT
A long-term program is in progress at JPL to reduce cost and risk of flight mission operations through a defect/error prevention program. The goal of this program is the reduction and ultimately the prevention of human errors. The main thrust of this program is to create an environment in which the performance of both the human operator and the computer system is optimized. Systems must be designed to enhance normal human performance; training programs must be designed to alleviate likely errors; and functions that are human-error prone should be automated. To successfully design and implement this program requires a theoretically motivated model of human problem solving and decision making based on current theories of human cognition. Further, such a model must be data-validated to ensure its ultimate applicability. Principles of cognitive psychology, human-computer interaction, and Total Quality Management (TQM) are used to analyze past errors and make changes to end-user applications and training requirements to prevent these errors in the future.

Using human error information for error prevention
Developing error-free software requirements is of critical importance to the success of a software project. Problems that occur during requirements collection and specification, if not fixed early, are costly to fix later. Therefore, it is important to ...
On error correction in macro-based circuits
We consider the problem of correcting errors in a macro-based circuit. Our formulation of the problem allows the correction of errors that arise both in the context of design error correction before the circuit is realized, and when a physical circuit ...
Incorporating Human Error Education into Software Engineering Courses via Error-based Inspections
SIGCSE '17: Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science EducationIn spite of the human-centric aspect of software engineering (SE) discipline, human error knowledge has been ignored by SE educators as it is often thought of as something that belongs in the realm of Psychology. SE curriculum is also severely devoid of ...
