Dealing with uncertainties

Consider potential changes in users' needs, requirements and external factors.

Create trust and openness around uncertainties.

Design contracts that allow for change, eg through contracting for a minimal solution.

Specify details where reasonable.

Build in pilots and process tests to pin down more details.

Design contracts that include agreement on the cost of potential future options.

Regularly monitor risks and uncertainties.

Keep data up to date and share with suppliers.

Consider how to reflect outcomes of pilots and other work.
