Performance appraisal targets

The central idea is that of performance appraisal against agreed targets. Managers are required to agree with each of their subordinates what the subordinate s objectives in his or her job should be over the next time period, typically six or twelve months. At the end of the time period, the subordinate s performance is assessed against these objectives and new objectives agreed for the next time period. 

Field appraisal Is most commonly targeted at reducing the range of uncertainty in the volumes of hydrocarbons in place, where the hydrocarbons are, and the prediction of the performance of the reservoir during production.
