So how does one know if one has a good idea? Assume most ideas are good and have value. It is often their timing that might not be ideal.
The questions to ask are really:
- Is this the right idea for the identified circumstances and people who will be implementing it? (e.g. if you have only have $5, and it's a $20 idea... or throwing a surprise party for someone who hates surprises)
- Can this idea be used effectively in the manner for which it is intended? Will it translate to actions well? (e.g. teaching a group of 5 year olds to bake & ice a layer cake...)
