BHAG, an acronym for Big Hairy Audacious Goal conceived by James Collins and Jerry Porras indicates long-term goals of companies. While BHAG encourages companies to have clear goals with commitment and confidence of stakeholders, it becomes pretty contradictory as we focus on SMART goals in Six Sigma when compared to goals with a time-limit of 10-30 years.
3 most important aspects which we can consider here for successful implementation of BHAG is: Zeal, Knowledge and Monetary. Would all the stakeholders have the same zeal to work-for 10 to 30 years..? Knowledge - Sufficient knowledge and information plays a critical role here, and finally - Monetary Returns for the company at the end of a project. Answer for all the 3 aspects is to be 'Yes' to think-over if we can use BHAG in the orgnaization.
Referring to SMART Goals vis-à-vis BHAG: while BHAG cannot be considered as a driving force for Black Belt Projects - Black Belt Projects can be considered as a driving force to achieve BHAG. Considering examples like NASA (landing a man on the moon and returning him safely to the earth), Google (organize the world's information), Tesla (accelerate the world's transition to sustainable energy), Uber (Transportation as reliable as running water, everywhere for everyone), Etc. - every organization must have a clear visionary Big Hairy Audacious Goals which should be a Superset of many Black Belt Projects.
