Stars, I can go all night on that subject, I can speak from a certain angle, retired military & Law Enforcement SuperIntendent here who work side by side Secret Service, AF1, other Federal such as DOE/DHS & State agencies, as well as, & city municipalities & host nations. Most work off of pre-budgeted policy or what some of used to call FinPlans. Fallout money comes into play in Aug/Sep to go along with new fiscal budget beginning Oct 1st.
During Summer Months, we come up with a 'Wish List.' Then we vote on what is feasible for each department to spend regarding cost-effectiveness & depending on what kind of funding forecast we actually get. TASER is a good example, there BOD had to make an effective price point to drive sales & make improvments/accessorize (Body Cams) until wide scale adoptability & price points maximized profits. Simple.
Things to consider;
1. Advancements YOY (Increased diversified workloads/propensity to scale up to tougher tasks)
2. Production cost YOY
3. Increased demand
4. Acceptable price points
5. Competition
When I talk scaleability, A city could get these to generate $1M yearly as a meter maid or DHS border LP/OP agent (intangable cost/value: dramatically improving country's security &social welfare). Hope this adds any insight to the collection of data.
IMO, anything under $5PPS should be considered real early.
