Summary
The objective of the FASGEP project was to develop a system for the quantified fault analysis of safety critical
software development processes, their related procedures and practices, so that the probability of fault introduction
and the overall reliability of the software can be established at the earliest point in the lifecycle.
The more detailed goals were:
· to establish a mechanism for predicting the number of generated and residual faults in delivered software;
· to identify and characterise faults existing in current software generation processes;
· to determine “goodness factors” for elemental software generation processes;
· to produce estimates of the probability of residual faults showing up in software delivered for final testing;
· to implement the project findings in a “usable” form.
For a description of the main results of the project see section 11.1, Prediction fault rates during software
development.

Summary
The purpose of the FRESCO project was to improve the process of assessing the dependability of safety-related
software products and systems by identifying and proposing a framework in which such assessments can take place.
The project sought to:
· establish industry requirements for a conformity assessment and certification scheme;
· define the organisational framework for conformity assessment and certification schemes;
· develop a technical approach to conformity assessment.
The project has developed a method, supported by assessment criteria, which enables conformance to draft standard
IEC 1508 to be assessed. The method is modular and sufficiently flexible so that organisations may adopt IEC 1508
