What are the main differences between core purposes and BHAGs?

Both are very close to each other, but still there is a minute difference that:

The Core purposes are seldome to the company business plan as a fixed, long term and founded as a basic strategic plan.

The BHAGs are changeable and short term policy created by founders or equivalent authority screening the strategic plan availability.

The core business is the main function of the copmany, but BHAG is the strategic view to handle the business

I agree with Mr.Tohamy

As a company, your core purpose is equivalent to yor mission. 

If you accept this to be true, then the major difference is that you canhave only one mission but you can have many BHAGs.

mission to get the qualitative objectives in the market/community

THE MAIN DEFFERANCE IS THE CORE PURPOSES MUST HELP THE BHAGs

I agree with both

-          Core purpose—not some specific goal—is the reason why the organization exists. A BHAG is a clearly articulated goal.

-          Core purpose can never be completed, whereas the BHAG is reachable in10 to30 years.

-          Think of the core purpose as the star on the horizon to be chased forever; the BHAG is the mountain to be climbed. Once you have reached its summit, you move on to other mountains.
