If you are to choose between a risky marketing plan that if you can pull off, will boost your profit, and another one that is stable and guaranteed?

Sir, It depends. Do you desperately need sales volumes to move your organization from loss side to profit side, or beat out our compititors and your market is dynamic enough, risky decision should be taken to take advantage. However if you are already market leader, risky decision should not be taken as these may put your company under bad reputation (if step taken fails)
