The One Minute Manager makes it clear

• what the employee's responsibilities are,
• what they're accountable for.

Once understood, each goal is recorded on a single page. The goal and its performance standard should consist of one or two paragraphs that can be read in a minute. The employees should have access to assist with aligning themselves with their goals.

Employees know how they're doing when a manager clearly communicates this to them.

When a manager sees you doing something right, he tells you exactly what you did right and shares how good he feels about what you did. The key is to act immediately and not wait for appraisals. 

This technique will help the employee to understand what specific behaviour is required. It will accelerate the learning process and improvements.

When a manager sees you making a mistake, the reprimand does not exceed a minute. The manager is specific about what you did wrong. He shares how he feels - frustrated or annoyed - and when the reprimand is over, it is over.

The manager never attacks a persons value, only reprimands the behaviour. Acting quickly prevents disasters and encourages success.
