How this activity improves the chances of your future IT project being a success?
Work breakdown structure provides the project management team a way to define and group a project discrete work elements that organize and define the scope of the work for the project end results. WBS provides a framework of tasking to create detailed cost estimates and scheduling at the most detailed and accurate level if possible. The WBS provides the project manager, team, stakeholders, and customer a scope of whether they are capturing the necessary task based on the requirements for the project. The benefit of using WBS:
- With WBS, its good to assigned specific task to members, it creates accountability for team member tasks that are schedule to be completed. So, each team member have to be commitment to complete their task and participant in team discussion.
- forcing team members to capture and create detail steps. The activity encourages team members to communicate to clarify any issues, talk about any assumptions, narrow the scope of the project and raise any critical issues early.
- develop effective scheduling and good budget plan for the project.
WBS is a process, it will probably take time to learn the ins-and-outs of successfully implementing work breakdown structure with a project but the outcome will be worthy it. WBS can make a project planning and executing easier, and provide a ground layout of scheduling and budgeting. WBS is a good way to see what area, or member causes the project to fail, not holding the project manager accountable but the that particular team member. Implementing WBS process into the company project will change the failure rate dramatically.
