Rating all the risks (as do the analysts) is probably leaving you with paralysis (by analysis).
Subsequently you end up doing nothing (like some civil servants).
A day only has 24 hours - sometime you can trick a bit and make it 30 (not for long time).
Finding the market can be difficult (some times).
Going national and global is also challenging (how, with whom, what channels), Investors are not easy to find and then they do not understand anything else than cash flow or make life miserable for the CFO and the CEO.
I am advisor in High Technology area and I coach start-up to success - I have seen some client go bankrupt due to cash flow crisis and poor front and back office procedures coupled with unrealistic go to market decisions.
Many valid product do not make it to market glory because current incumbent dinosaurs do block new entrants and stifle innovation. Some investors deliberately under invest to kill off or take control of a "diamond" opportunity.

The current financial crisis (a systemic break down and unlimited greed of the liberalized western financial community) we are in now will continue. One must be extremely careful with the money you spend, how you spend it. One needs near real time analytical information on where do we stand now (this can be automated - ask me how) - the cost of mismanaging information is huge - when well manged the decision making processes are easier however one is still dependent on micro and macro economic realities.

Right product too early (or too late), poor competitive SWAT analysis and you are cooked !

One must be very capable of choosing the right and loyal team - ideally from very different areas and experience - then take step by step forward to test market, get client, monitor competition, add value, improve product, network with many people and organisations.
