Research a recent (within 5 years OK) software defect or hack. Apply the simple cost modeling calculation we reviewed in Lecture 1 and write a 1 page (single spacing) word document presenting your argument of how Quality Assurance and proper testing techniques could have lowered and saved defect costs at which stage of the development life cycle. Identify where in the process testing could have been applied to catch and correct the error and reduce the cost. Describe what you would have tested to prevent the defect from happening.
