Defect prevention with orthogonal defect classification
Ajit Ashok Shenvi · 2009
"Learning from the past" to make systems more efficient in terms of cost and time is the hallmark of any engineering discipline. Prevention of defects is the "holy grail" of "learning's from the past" i.e. every product generation we learn from our defects and prevent it from recurring in the next generation. Taking this philosophy further "capturing defects in the earlier stage of the life cycle" is a means of preventing defects in the later stages of the product life cycle. Correction of defects is costly and the cost increases exponentially with every subsequent stage. This also impacts the cycle-time directly. Defect prevention then not only helps in cost reduction but also helps in cutting down the development time.
