Written performance objectives give the employee and employer a common ground to understand what is expected on the job. Many times these objectives are tied directly to an employee's yearly pay raise. In order to create an atmosphere where employees feel empowered to do their jobs well, a supervisor should sit down with each maintenance mechanic and create a list of performance objectives that they are to meet by the end of the year. Supervisors should ensure that objectives can be measured and documented and that they are realistically attainable for the specific employee with regard to his job duties.

Refrigeration, Heating and Air-conditioning Mechanics

Refrigeration, heating and air-conditioning maintenance mechanics install and maintain piping, duct work, motors and refrigerant lines. They may have a daily maintenance route made up of either residential or commercial customers. These types of mechanics must make sure to properly dispose of all chemical refrigerants, establish that there are no leaks in the mechanical system, and ensure that the system operates properly before moving on to the next customer. A job objective for this type of maintenance mechanic might read, "Respond to all customer service calls within three business days. Ensure properly functioning air-conditioning equipment and dispose of all refrigerant materials as described by company policy."

Aircraft Mechanics

Maintenance mechanics that work on airplanes must do constant maintenance in between airplane takeoffs and landings, as well as performing a specific string of tests based on the aircraft's age and mileage. Landing gear, engines, instruments, and fuel lines are all inspected and tested to ensure a safe flight. Aircraft mechanics need to be certified by the Federal Aviation Administration (FAA) in order to maintain aircraft, and the FAA also requires that aircraft maintenance mechanics keep their knowledge up-to-date with 16 additional hours of training every two years. A sample performance objective for an aircraft maintenance mechanic is: "Ensure 100 percent on time and accurate maintenance in accordance to all FAA regulations and company policy with zero escapes in process."
