Final answer:
Charles Perrow's idea in Technology and Organization Design implies high task variety at the organizational level, focusing on the complexity of tasks and team-based approaches to work within modern organizations.
Step-by-step explanation:
In Charles Perrow's concept of Technology and Organization Design, task variety refers to the range and types of tasks that need to be accomplished within an organization or by a team. Perrow's idea suggests that analyzing technology and its impact on organizational design involves considering the complexity of tasks (variety) and the level at which the tasks are analyzed (unit of analysis). When discussing task variety and the unit of analysis in terms of Perrow's idea, it seems we are looking into how work is structured within organizations, specifically about the increasing reliance on team-based versus individual approaches to work.
In this context, considering Perrow's perspective on organizational level analysis and the way modern organizations tend to delegate complex tasks to teams, we can argue that the work done in today's organizations tends to be of high variety and is focused on the organizational level rather than on individual tasks or group levels.
Therefore, the answer to the question 'What is the task variety and unit of analysis in Charles Perrow's idea in Technology and Organization Design?' would be b) High variety, organizational level.
