Every IMO will usually have strengths in more than one skillset. They might be an expert in Mapping, but also be comfortable doing basic visualization and also coordinating an IM Working Group meeting on CODs. We call these IMOs 'Generalists', because they have multiple skillsets. Other IMOs are 'specialists' because they spend almost all of their time working in a single skillset. The head of an IM team, for example, might not have very strong technical IM skills, but be very experienced in the 'coordination' skillset. We call this IMO at 'specialist', because they are particularly strong in one skillset (coordination) but not in the others.
A small team, especially offices that have only one or two IMOs, will need to have generalists, so they can still perform all of the activities of an office. A large office, meanwhile, can afford to have multiple specialists. When building a team, it's vital to choose staff in a way that ensures the team includes all of the skillsets, regardless of team size.
