Defining the main thing to get right is the first step. For the corporation or business units, this might be expressed in terms of a strategy. For departments, this might be expressed as the purpose or the main things to get right. For HR departments using the new Human Capital Strategy, there are two things to get right: (1) to ensure that the organization can deliver its annual business plan, and (2) to continually improve performance of those in critical roles. Job descriptions, job evaluations, incentive and benefit programs, and the like must align with one of those two objectives. The main thing starts from the top and works down.
