Name the following performance appraisal documents based on the format, features and inclusions described.

a) Tool used to assist performance improvement of underperforming employees or those employees who have demonstrated unsatisfactory behaviour and conduct in the workplace.

b) A numeric rating scale, often 1 to 5, with 1 being unsatisfactory and 5 exceeding expectations. The manager rates an employee's performance on a variety of job behaviours, e.g., quality of work, punctuality, initiative, teamwork, etc., and will support the rating with examples of performance.

These are areas of behaviour that have critical significance to the performance of the job role, either positively or negatively.
