According to statistics hardly 1% of the ideas succeed. I would agree good ideas are important but the factor which play bigger role in the success of the business is execution. According to O’Really blog, brilliant ideas are worth only 20% of the whole business, rest is how its executed.
And, for anyone who’s ever built up a success, you quickly learn that execution is everything. The initial ideas are usually completely meaningless.
Could you provide the URL of statistic you are referring to (O’Really blog) ?
