This can be described as a hierarchy of tasks or jobs to be done. The work breakdown structure defines the scope of work, identifies what specific tasks need to be done, and assigns responsibility to individuals or subunits. The work breakdown structure facilitates the planning process, especially when dealing with larger jobs. The project manager at Craft Construction is usually responsible for any planning and scheduling that takes place on a specific project, including preparing the work breakdown structure and the actual schedule of events. This manager performs the initial planning and scheduling of tasks and costs, and then hands it down to the lead carpenter, who is responsible for carrying out the duties and getting the job done. Mr. Hollmann is one of the company's lead carpenters. Managing projects carefully is very important for Craft. The project is broken down into phases, allowing the project manager to know what subcontractors will be needed, and more importantly, exactly when they will be needed. This is where the project schedule becomes quite handy. Project scheduling can be performed in many ways. Some of the more common and popular methods of project scheduling are network analysis and the critical path method of scheduling (CPM). Although companies do not always use these methods in there exact form, most do tend to use a modified version of one or both of these methods. I discovered that Craft does not use network analysis or CPM, but they do have a scheduling method that works for them and is quite similar to CPM. Network analysis is a visual representation of what needs to be done, and when it needs to be done. Networks are basically a technique to help management in the planning and control of projects. They also show relationships between the different tasks that need to be accomplished. Networks are not only useful for planning and controlling, but they can provide a means of communication between the various departments that participate on the project.
