Which type of performance appraisal is being used in companies?

Dear Mr. Ahmad, Thank you for addressing your question to me. We use PPI , Personel Performance Indicators. These are service focus format that Front line Sales personnel submit every week, Area Managers submit every fortnight and Regional Managers every25 days and Department heads every29 days and business head every30 days and CEO  submits every7th of the month to the Chairman and board. Hope this information is useful to you.
