You need to sit down and study your organisation and each staff designation. Then write the questionaire for each designation based on what happens in YOUR organisation.
The performance appraisal for a person who works as a sales rep for a chemical company is totally different to say a teacher in your organisation.

If you lack the skills and qualifications to do this, then you need to outsource it to an professional and get it done correctly.
