Patent ID: 8356283

Claim:
A method for determining a relative fault risk measure for a build of a built system comprising a set of build elements, said method comprising the steps of: identifying, by a computing device, a reference build of a built system; assigning, by the computing device, a base value to a fault risk measure for said built system; assigning, by the computing device, a risk weight to each build element in said built system; identifying, by the computing device, the set of build elements that have been changed in a further build of said built system; applying, by the computing device, a set of test cases to said further build; identifying, by the computing device, the subset of said set of changed build elements that have been tested; calculating, by the computing device, a risk increase factor based on the sum of said risk weights of each build element that has been changed and not tested; calculating, by the computing device, a risk reduction factor based on the sum of said risk weights of each build element that has been changed and tested; and updating, by the computing device, said fault risk measure by including said risk increase factor and removing said risk reduction factor.
