What role do executive departments and agencies play in the policy-making process?

Executive departments and agencies play a role in policy making through participation in the making of laws. Although the executive does not directly make laws, the departments and agencies can suggest laws. The executive departments and agencies also implement and enforce new laws that establish policy,.

I believe the answer is: they directly implement and enforce new laws that establish policy

The creation of new implemented laws and policy are most influenced by high ranking legislative officials who are eligible to give their votes

The executive departments had the full right to make necessary steps that could put those new laws and policies into realization.
