A project manager constantly strives to achieve balance in the cost-schedule and quality equilibrium of the project. One of the techniques used to successfully manage the project is WBS. Work breakdown structure is a tool to break a project into its manageable components. It is basically a task list. WBS provides a detailed illustration of project scope. It clarifies the individual and team work assignments and builds those into an overall picture.
WBS becomes the basis for monitoring the progress as identified smaller parts become measurable units.Work breakdown structure also provides accurate cost and schedule estimates for each of the tasks or components.
Project definition and risk management are the stepping stones on which work breakdown structure is built upon. Project deliverables provide the activity that defines a task. This step can be quite overwhelming. For example in case of a large project, it is not possible for a project manager to list all the detailed sub tasks required to complete a high level task in the project. He or she has to involve experts and other team members in the planning process.
In a multidisciplinary project, outside subject matter experts, contractors and vendors may be employed to do some of the work in a project. They may be required to provide their own work breakdown structure.
Work package size is another key concept which helps keep tasks meaningful, manageable and under control. General guidelines of a work package ensure that tasks are accurately estimated, assigned and tracked. It makes a project manager's job a little less arduous when a work package is of correct size.
