Evaluation and control are integral to management. Evaluation assesses results, outputs, quality, impact and effectiveness. It can be performance or program evaluation. Control ensures tasks are done efficiently to achieve objectives. The control process establishes standards, measures work, and takes corrective action. There are various instruments for employee evaluation like rating scales, ranking, and forced distribution. Program evaluation determines if a program achieves its goals using measures like cost-benefit analysis and cost-effectiveness. Communication is also important for organizations to coordinate work and integrate units.
