Make a supported decision
Choose an option, explain why it fits and test it against an alternative.

Use a clear test
Start with the aim. Compare how well each option meets it. Use the resources to support your reasons, then explain a drawback or condition.
Two people can reach different decisions if they use accurate evidence and explain their priorities.
- Meet a town’s water demand
Balance capacity, habitat and uncertain savings.
- Protect a coastal road
Compare direct protection and repeated beach maintenance.
- Improve access across a city
Consider cost, waiting time and step-free journeys.
