Fixing software failures is easy. Diagnosis is the hard bit. Reproducibility is the fundamental challenge in application debugging / resolution technique. There are times when it's simply impossible to replicate what the customer is trying to do.
Software flight recording technology solves this problem by recording what your software was doing before, during, and after the defect occurred - so you can see what your program did and why.
