The project management team at Parallel Services is having a debate about how to define tasks in the work breakdown structure (WBS). Ann, the project manager, wants to break tasks down into the smallest possible units. For example, she objected to a broad task statement called Develop a training schedule. Instead, she suggested three sub tasks:

(1) Determine availability of training room,

(2) Determine availability of attendees, and

(3) Selects specific dates and training times. Karen, another project team member, disagrees. She feels that the broader task statement is better because it allows more flexibility and will produce the same result.

Karen says that if you break tasks into pieces that are too small, you risk over managing the work and spending more time on monitoring than actually performing the tasks. As a member of the team would you tend to agree more with Ann or Karen? What are the pros and cons of each approach?
