Presentation from MSDN Live 2010 on Solution Architecture. Core ideas in the presentation is that we continue to fail in a large scale in the IT-industry and it's time to reduce complexity in our solutions and systems to improve the success ratio of IT-investements.The slide decks are very simple and not a lot of content, therefor all the notes are included with the presentation. Suggest anyone reading this presentation to download the original file with full comments and notes.

1. Status Quo:$6 trillion
31% success$11.5 million/sec
2. Challenges:- Complexity number
one- Security and many
other- 25% more features, 100% more complex
3. The Solution:- Least complex
architecture- Achieved by You- Let’s go for 8% improvement!
