I could write forever on this topic. Here's one item:
With citizens as the customer, I would try to apply agile (a software development methodology) tenets to government. For example, I would have a poll to determine the priority of requirements to be fulfilled by congress each month. I would hold congress accountable for fulfilling the requirements and reporting back to the citizens the status of each requirement each week. Bipartisan teams would be assigned to each requirement. Any conflict that can't be resolved by a team would come to me for the final decision (no appeals to my decisions - to pressure the teams to get the job done). Penalties would be incurred by teams failing to complete their tasks (e.g., cuts in privileges/pay). I could go on, but you get the idea.
