&lt;br /&gt;
Learn from this and prevent death train projects.&lt;br /&gt;
&lt;br /&gt;
Screw white vs. black outsourcing. Let every party use the tools and processes they want to use and make a great product. But make a prototype before you freeze the spec, keep in close contact with your colleagues and your outsource partner. Because your customer will see and use your outsource partners product but see your logo on it. &lt;br /&gt;
&lt;br /&gt;
So, make great products, each doing your own thing using trust and open source software.&lt;br /&gt;
