Let me tell you a (probably-apocryphal) story:<p>There was a giant multinational hamburger chain where some bright MBA figured out that eliminating just three sesame seeds from a sesame-seed bun would be completely unnoticeable by anyone yet would save the company $126,000 per year. So they do it, and time passes, and another bushy-tailed MBA comes along, and does another study, and concludes that removing another five sesame seeds wouldn&#x27;t hurt either, and would save even more money, and so on and so forth, every year or two, the new management trainee looking for ways to save money proposes removing a sesame seed or two, until eventually, they&#x27;re shipping hamburger buns with exactly three sesame seeds artfully arranged in a triangle, and nobody buys their hamburgers any more.<p>(<a href="http:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;items&#x2F;2007&#x2F;09&#x2F;11.html" rel="nofollow">http:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;items&#x2F;2007&#x2F;09&#x2F;11.html</a>)
