Train Wreck Of A Newsletter ?
The Newsletter seems to focus on the cost involved to fix a software problem within the software team.
There are numerous other teams involved including testing, production, shipping, field engineers etc. (not to mention sales & marketing - ok I just did !).
If a defect is detected early and self contained within the development team and rectified within a timely manner the others teams need not be involved hence the costs can be relatively small.
However, defects are often like snakes and ladders causing a design to go back many steps & teams possibly to the very beginning: it doesn't take an expert to figure out the cost is generally cheaper the smaller the snake !
