• From whom this information will be collected; • How it will be collected; • Who will collect it; and • When it will be collected. The mandate, the priorities established by the commission/mission and the elements of each alleged violation will help define the information requirements. Establishing the information requirements will assist in determining what information will have to be collected to meet these requirements. The selection of the most appropriate method of collection will depend on a number of issues including ease of collection, risk to the victim, witness or source and/or to the investigators, access to the source, urgency and resource availability. The example below is a simple matrix showing the key aspects of an information collection plan.
