A decision record keeps the important comparison outside your head. State the choice and deadline, list feasible options, then record the requirements, sources and unknowns that distinguish them. Include waiting or keeping the current arrangement when those are real options.

For a venue choice, compare each offer against the same needs, identify anything still unconfirmed and state what could change your preference.

Writing the comparison down is only a prompt to think. Relevant information, thoughtful use, feedback and suitable review still matter. Training can help on some judgement tasks; neither a course nor a mandatory form guarantees an unbiased choice.
