Dear Friend,
Everything is available in the Internet. For instance, in respect of your query on MBO, just for your sake, I got authentic information from Wikipedia for MBO, whichh is as follows:
Management by Objectives (MBO) is a process of defining objectives within an organization so that management and employees agree to the objectives and understand what they need to do in the organization.
The term "management by objectives" was first popularized by Peter Drucker in his 1954 book 'The Practice of Management'.[1]
The essence of MBO is participative goal setting, choosing course of actions and decision making. An important part of the MBO is the measurement and the comparison of the employee’s actual performance with the standards set. Ideally, when employees themselves have been involved with the goal setting and choosing the course of action to be followed by them, they are more likely to fulfill their responsibilities.

1. Definition of the rating scales
• The Rating Scale is a form on which the manager simply checks off the employee’s level of performance.
• This is the oldest and most widely method used for performance appraisal.
• The scales may specify five points, so a factor such as job knowledge might be rated 1 (poorly informed about work duties) to 5 (has complete mastery of all phases of the job).
Hence, please take the trouble of going to internet, post your query in the web browser on the topics you want and presto, there you are !
Best of luck
