Chapter 6: Planning for Software Quality 143 Figure 6-3: Quality is affected by the balance of the Iron Triangle. Quality Scope So how much quality is enough? When it comes to software development, you may create a scale of errors, bugs, and gremlins that sneak into the code. For example, you rank the bugs you ve identified from 1 to100, with 100 being the most severe. Any bugs below a score of 20 may be accepted for now, while everything over 20 needs to be fixed. Some organizations, however, would like to aim for a zero-tolerance policy on bugs. Sounds great, but is it possible or profitable? First, consider the possibilities. How do you know an error exists until someone finds it? You can test, complete peer reviews, and hire third parties to examine your code for months or years on end and not find errors. Does this mean there are no errors within the software? No, it just means that none have been found yet. Now, consider the profit. If your organization spends months or years examining, inspecting, and testing code, the market window can easily open and shut for your software before you even get the program packaged. And who pays for all of the inspection? It isn t feasible to demand perfection on most software projects because of the time and expense to prove the existence of perfection (or more accurately, the absence of known errors). Examining optimal quality Optimal quality describes how much quality is expected in return for the cost to achieve that level of quality. For example, you could create a flawless piece of software that allows users to track all of their online purchases, shipping expenses, and even the interest for each item purchased with their credit cards. But, would anyone buy the software if you charged $600? This is what you might end up charging per copy because your project team spent months perfecting and testing the code.
