Operational control systems ensure day-to-day actions align with plans and objectives by focusing on recent performance and taking corrective action when standards are not met. The process of evaluation involves setting standards of performance, measuring actual performance against standards, analyzing any variances, and taking corrective actions. Standards are set by finding key performance areas and requirements, and measuring both quantitative metrics like profits and sales as well as qualitative factors. Performance is measured through accounting, reporting, and communication systems and analyzed by comparing actual results to budgets and standards.
