You need to address the needs of the stakeholders namely the Customers, Sharehoders/Debtors/Creditors, Employees, Suppliers and the society. Define your policy towards each of the above mentioned stakeholders.
If you search the net for Quality policy you'll get sufficient number of statements.
Policies could be:
- Improve customer satisfaction, increase ROI for shareholders, minimise employee turnover and so on.
In addition clause 5.3 requires a commitment to continual improvement to be part of the Quality policy.
Please remember that you will need to have quanitative goals against each of the policy statement and hence the policy should be closely aligned to the organisation's business plans.
