Every job purpose is performed by a person on the guidelines prescribed by the organisations that are called Procedures and Policies. Explaining how to do that job, these need to be clear about the major essentials like location, skills, time priority etc.
The procedures would explain the way to do the thing correctly while at the same time the policy would define what is the right thing.
Hence, a work requires different roles to be assigned called "RACI"
R= Response - Ability (The person who would know how to do the work)
A= Authority (The person who would be the final authority to decide anything related to this work and decides about the procedures and policies )
C= Collaboration role (A contributor and assigned person who would do the work )
I= Inform role ( A person who would be informed to control the whole plan and measure accountability )
