Thanks to Kristian Köhntopp I was reminded of this chart yesterday about the costs of a bug fix within a software lifecycle.
I decided to share this amongst my colleagues to make them aware of the risk they have to deal with on a daily basis.
I have seen this chart before on a presentation by Stefan Priebsch whom I can highly recommend to go and see when you have the chance.
Unfortunately I wasn’t able to track down the original source by Barry Boehm but even without a detailed explanation this illustration makes a point. Any bug that you can eliminate during requirement or design is worth eliminating.
Quick and dirty always comes with a cost only later and happening somewhere else probably in someone elses responsibility.

Sortware Project Survival Guide by Steve McConnell has a chart with similar data but it looks different.
This chart demonstrates Big Design Up Front, which has fallen out of favor in many circles.

That’s why importance of Junit or Unit Testing is so high best part is automated, repetitive and took less time in terms of other testing efforts. Thanks for reminder.

Am I evil if I imagine that the cost of bugs generates equivalent commercial opportunities for consulting companies, selling task force to enterprise in order to deal with the mess ?

@hadrien the opportunity is clearly visible but in my experience this is rarely a job any consultant fancies as the overall costs can be so high and the work so messy that it’s hard to finish such a job on time and in budget.
