An SPI would answer six questions that every member of Parliament and citizen is entitled to know before a Bill is considered:   

1. Need  Why is the policy needed?   

2. Objectives  What is the policy’s objective in terms of the public interest?   

3. Options  What alternative policies and mechanisms were considered?   

4. Analysis  What were the pros/cons and benefits/costs of each option considered?   

5. Pathway  What are the timetable and steps for the policy’s rollout and who will administer it?   

6. Consultation  Were the views of affected stakeholders sought and considered?   

This would encourage good policy making.
