To make things worse, organizations that are into Zero Defects will add quality (check) points that will slow down overall delivery but “ensure” these defects will never be repeated despite the fact that the process is not actually adding value. The Zero Defects movement assumes that all defects are equal and requires teams to spend time analyzing and resolving them without ever considering ROI. Also, if we consider Return Of Investment (ROI), some defects at the bottom of this scale may never be taken care of at all. In the real world, we prioritize defects and take care of them in order from greatest to least importance. But then why are they motivating people to work towards something that is not possible? Wouldn’t it be better to just use something as the “Defect Reduction Initiative” instead of a Zero Defect approach? When did all defects become the same? Those who promote the philosophy of zero defects say that the quest for perfection, even though everyone knows it is not possible, will at least increase quality. ![]() In reality, especially when we are talking about software development, it is just not possible to have zero defects. OK, before we go any further we need to address this question the answer is NO. Zero Defects certainly seems good in theory, but how does it actually apply to software development? The following are few things that you should be aware before starting such initiative in your organization: Is Zero Defects possible? This is done assuming that the cost of preventing problems is less than fixing them later. Its purpose is to design every process so that it is not possible to produce something of low quality. The ultimate aim of the theory is to reduce the level of defects to zero. Zero Defects is a Lean philosophy, a mentality, or a movement introduced by Philip Crosby* that aims to reduce and minimize the number of defects and errors in a process in hopes of getting things done right the first time. ![]()
