by Dwayne Phillips Sometimes it is better to see the Eiffel Tower from across town instead on being on the Eiffel Tower and seeing the slums. I’ve seen many photographs of the great pyramids in Egypt. I have only seen a few photographs of the city next to the great pyramids. Yikes. I prefer the […]

by Dwayne Phillips Should we be using systems engineering on this project? Here is a simple test. I think systems engineering is useful and brings many benefits. That is why I wrote a short book on the topic. The book is free here. Should we be using systems engineering on this project? Here is The […]
