The Work Breakdown Structure (WBS) tasks are the basis for the project manager’s assignments to the team members. They are used to estimate costs and the schedule (duration). It is also the framework for reporting the project’s status to the sponsor. The WBS is central to everything a project manager does and plays a major role in determining the project’s success. You build this network of tasks by breaking down the project scope and major deliverables. The Work Breakdown Structure (WBS) contains everything that the team must produce to deliver the project scope. Main WBS Work Breakdown Structure Page
Work Breakdown Structure Tasks – Questions
People always have questions about how to build the Work Breakdown Structure (WBS). They often ask how big the WBS should be and how many tasks it should have. There is no magic number of tasks in a project. The number in your work breakdown structure depends on the capability of your team members. You need to consider a number of factors.
- What is the correct duration for the assignments I’m going to make to my team?
- How frequently do I want to receive status data and estimates to complete from my project team and vendors?
- How often do I want to update the project schedule with current data?
- How risky are the tasks in this project?
Work Breakdown Structure Tasks and Team Capabilities
As you can see from this list, you design the tasks in the Work Breakdown Structure to fit your management style and the capabilities of the project team members. In this article, we’ll consider the team member’s capabilities. If you have a project team made up of experienced professionals who have performed their tasks dozens of times, your work breakdown structure will have a small number of large tasks. The tasks will have longer durations because these experienced professionals can handle assignment durations of 7 to 21 days. you should give experienced professionals larger, more challenging assignments and the independence and decision-making freedom that go with it.
However, not every team is composed of project superstars. You’re going to have some people on your team who have some experience with projects and know their jobs but for whom a two-week assignment would be discouraging and maybe even intimidating. So for these people you’ll design task assignments that are about 5 to 7 day’s worth of work. You’re still giving them responsibility for an important deliverable but you’ve broken it up into smaller pieces. That lets you track their work more frequently. Frequent deliverables are a major factor in the accuracy of your status reports. That’s because even before a deliverable is finished and accepted, your team members report how much work they’ve completed and how much work remains to be done.
Finally, you may have a team with new hires or people who have little experience with your company. Or they may have limited expertise in the technology of their task or no experience working on projects. With these people, you want to break the assignments into small pieces where they have a deliverable to produce every day or two. You would have a large work breakdown structure containing smaller tasks with short durations. That kind of Work Breakdown Structure works best with inexperienced people because you will be expecting several deliverables from them every week. This gives you the opportunity for frequent feedback on their work and coaching to improve their performance. With these newer team members, it is a valuable motivational technique to increase the size of their assignments as they demonstrate their ability to produce deliverables on time and within budget.
Designing your Work Breakdown Structure with these team member considerations also allocates your time properly. You don’t want or need to spend a much time reviewing the work of one of your experienced project superstars. That kind of micromanagement will irritate them and interfere with their feelings of independence and professionalism. That’s why you give them the biggest assignments with the longest duration. The people who need the most review of their deliverables will have the smaller assignments and shorter duration. That’s where you’ll spend most of your time.
Work Breakdown Structure Task Risks
The last consideration in the Work Breakdown Structure is the risk of each individual task. They can affect the risk of the project as a whole. If one or two of the high-level deliverables have a high risk of duration or cost overrun, you’ll break down those major deliverables into smaller pieces. Some examples are deliverables that have a high risk of changes in technology or the technology is uncertain and cost overruns are likely. When you break down those major deliverables into smaller pieces, you’ll get reports on them every day or two. That prevents big problems from surprising you when it’s too late to fix them.
