Shipping Product

I come across this interesting but very true statement while watching Channel 9 :

#
If doesn't matter if it work on YOUR machine, we are not shipping on YOUR machine!
#

This remind us as developer of how important it is to test as extensive and as many configurations as possible. More than 90% of the time, the code will work on the developer machine since the developer machine usually have the necessary configuration, tools and libraries that are needed. Some of these are installed and configured without the developer know about it when he install the developer tools.

If you don't have so many machine for testing, consider to invest in virtual machine tools such as VirtualPC from Microsoft and VMWare.

The extra money and time to invest in extensive testing will save you a lot of face in front of your users/customer and reduce support effort.
