Try to set objectives because they help you improve rather than because a Standard says that you have to.
Complaints, Non Conforming Products and NOTIF are probably the most common objectives that are presented but they focus on negatives and in many ways they are in themselves out of your control.
Twist it around and identify the positive parts of your Quality System and operation which you can improve and which will hopefully help you to reduce your complaints and NCP etc.
Look at areas such as training, internal audits, supplier management, process control, cleaning and specification control etc.
eg
80% of production operators will receive refresher training by week 45
95% of internal audits will be carried out within two weeks of the scheduled date
60% of suppliers will be reaudited by week 50
95% of cleaning tasks will be completed according to the schedule.
90% of raw material specifications will be reviewed by week 48
Objectives such as these are measurable and will contribute to meaningful continuous improvements.
