No, not all the effective organization are efficient.
Are all effective organization efficient?
Yes, an effective organization would be more efficient than a non-effective organization. All organizations have an effect, it is just a matter of a negative effect or a positive effect, and its efficiency
Absolutely not. Say your organization 'sells'. They may be consider the top dog in the marketplace and by the competitiors and producer of the product they are selling be called market effective. But if they do it without margin and cannot stay in business they are efficient in fact they are deficient and likely out of business.
