What Dictates Success?

Our school's long range technology plan is almost complete. A part of this planning process is meeting with similarly-sized and resourced schools to determine where our own resources are going as compared to others'. It has been an interesting process and got me thinking about what makes for a successful technology department. I tend to think in pictures, so I created these images of what I think is a positive feedback loop and what makes a negative feedback loop. However, I am quite sure they are incomplete or too simplistic. What am I missing?
