Robert Stake (2005) makes the point that "a case is a noun, a thing, an entity; it is seldom a verb, a participle, a functioning" (p4). I am researching a process (monitoring and evaluation) in different organisations (what Stake may refer to as a function). Can the process of monitoring and evaluation be defined as the 'case' for the purposes of conducting case study research? Or is it more appropriate for me to define the organisational entity (or team within the entity) as the case?
