4K1 Software is devilishly hard to inspect.
Serious errors can hide for years.
Consequently, many are hesitant to employ software in safety-critical applications and all companies are finding correcting and improving software to be an increasingly burdensome cost. This talk describes a procedure for inspecting software that consistently finds subtle errors in software, software that is believed to be correct. Reviewers exploit the hierarchical structure of the code rather than proceeding sequentially through the code. Reviewers focus on small sections of code, producing precise summaries that are used then inspecting other such sections. Reviewers proceed systematically so that no case, and no section of the program, gets overlooked.
