Can you impose core values or core purposes on people?

Very nice question, I would say, the core values and core purposes are imposable to every person except those who are not core persons of the organization, generally.

Just if they have the intention

Core values would have no meaning if imposed. It has to be deliberated and it's importnace ought to be understood.

No and agree with Mr. Tohamy

m agreed with arinjay,,,but we must try hard to make it happen.

yes .

sometimes we lock to the person as a project

You cannot impose new core values or purpose on people. Nor are core values and purpose things people can buy into.

Executives often ask, How do we get people to share our core ideology? You don’t. You can’t. Instead, find people who are predisposed to share your core values and purpose; attract and retain those people; and let those who do not share your core values go elsewhere. Indeed, the very process of articulating core ideology may cause some people to leave when they realize that they are not personally compatible with the organization’s core. Welcome that outcome.

It is certainly desirable to retain within the core ideology a diversity of people and viewpoints. People who share the same core values and purpose do not necessarily all think or look the same.
