Start With The Vehicle Requirements
Use this collection when the next decision is which van configuration to investigate. The comparison article below provides a starting point; turn your own requirements into a short record before comparing individual vehicles.
Keep The Options Comparable
Give each candidate the same list of requirements. Keep documented facts, your observations and unanswered questions distinguishable, so an attractive feature does not hide an unresolved requirement elsewhere.
Use the decision log for those open questions and alternatives. When the scope is defined, the cost worksheet can hold the planned items and their sources.
