Why is proper onboarding so important? Your organization, and the applicants who want you to hire them, invest a great deal of time and resources in the hiring process. During the selection stage, the hiring manager will make the decision to extend an offer of employment with the assumption that the applicant will fit in and be an effective performer who is satisfied in the position and committed to your organization. The applicant accepts a job based on the same assumption.It follows, then, that onboarding is an important subsequent step in solidifying those decisions. It increases the likelihood of achieving the organization's expected outcomes, i.e.,effective job performance, job satisfaction, and commitment to your organization.
