What is Work Breakdown Structure – The progress of a software project relies on a successful work breakdown arrangement and its compatibility with the method system. Despite the fact that the principle and practise of using a WBS are well known, the published literature largely avoids this subject.
This is due to the fact that the development of a job breakdown system is influenced by factors such as project management style, corporate philosophy, client preferences, financial limitations, and a variety of other difficult-to-define project-specific criteria. Context information on machine-oriented job breakdown systems can be found in Software Engineering Economics [Boehm, 1981].
A Work Breakdown Structure is simply a hierarchy of elements that decomposes the project plan into the discrete work tasks. Below is the following points for a Significant Work is:
- A delineation of all significant work
- A clear task decomposition for assignment of responsibilities
- A framework for scheduling, budgeting, and expenditure tracking
Product subsystems, modules, functions, organizational units, life-cycle periods, and even geographies may all affect the decomposition of work into discrete tasks. The majority of structures have a subsystem-level decomposition. Subsystems are then broken down into their constituent parts, one of which is usually the software. If the program is the whole project or only one part of a broader scheme, this section focuses on software WBS components.
The organizational map of a job breakdown system details all of a project’s phases, making it an important project management method for organizing and scheduling. The final deliverable sits above the map, while the stages below it separate the project scope by indicating the steps, deliverables, and activities required to achieve it.
To plan and perform a task breakdown structure, project managers use project management tools. Project management tools can be particularly useful for organizing, arranging, and executing tasks when combined with a Gantt map that implements WBS hierarchies.
Levels in a Work Break Down Structure
In project management, a work breakdown structure (WBS) breaks down big, complicated tasks into smaller, more manageable chunks to make them easy to prepare, schedule, and execute. To aid in the preparation, implementation, and monitoring of projects, tiers of project deliverables and tasks are developed. There are four main levels of a WBS, which are outlined below:
- The Top Level: Project title or Final Deliverable.
- Controls Account: Main phases and deliverables.
- Work Packages: The group of tasks that lead to the controls account level.
- Activities: The tasks needed to complete the work package.
Types of Work Break Down Structure
There are two types of job breakdown structures: deliverable-based and phase-based. A deliverable-based WBS defines the project’s deliverables and scale, while a phase-based WBS shows the final deliverable on top, with the five stages of a project shown below (initiation, planning, execution, control, and closeout).
Clearly, a work breakup structure is a versatile instrument. A plain numbered list (also known as an outline view), a straightforward tree diagram, or even a Gantt map may all be used. When a Gantt map is part of a broader project management tool, the Work Breakdown Structure (WBS) can be used to schedule, delegate, report, and document the team’s progress.
Some Common types of Work Breakdown Structure are:
Verb-oriented WBS : It defines the deliverables in terms of actions.
Noun-oriented WBS : It defines work in terms of components
Time-phased WBS : It breaks the project into phases for long-term projects.
Why use Work Breakdown Structure?
The first step in creating a project plan is to create a work breakdown structure (WBS). It sets out all of the activities that must be completed (and in what order) in order to fulfill the project’s priorities and objectives. You and your resources will work on identifying mission-critical projects, their subtasks, and the interdependencies between them by visualizing the project in this way.
Cost analysis, resource utilization, and risk evaluation are all critical project management processes that benefit from a well-designed WBS. A WBS also aids in the avoidance of typical project problems such as missing deadlines, complexity creep, and cost overrun, to name a few.
In other words, a work breakdown system acts as a road chart for completing difficult tasks. A project can be broken down into stages or smaller sub-projects, and such sub-projects can be broken down into deliverables, sub-deliverables, and task sets! As a result, you’ll have a better understanding of the information required to complete any part of your project.
How to create Work Break Down Structure?
A job breakdown framework can be generated in five stages. These are the big steps in a WBS, the bird’s-eye view that finally leads to the granular stage. However, understanding the key components and what is necessary to create a robust WBS is helpful. Some of the important things to keep in mind, while creating a Work BreakDown Structure are:
- Define the project’s priorities and targets. Begin by determining and describing the project charter, which includes the scope, priorities, and who will be involved in the project.
- Split the broader project declaration of intent into a sequence of stages that will carry it from inception to execution at the next stage down, project phases.
- What are the deadlines for the deliverables? Create a list of all of them, and make a note of what is needed for such deliverables to be considered effective (sub-deliverables, work packages, resources, participants, etc.).
- Break down the deliverables from above into all of the tasks and subtasks that are needed to complete them. Make a note of what you ought to do.
- Assign the assignments to the squad now that they’ve been laid out. Provide each team member with the tools, services, and authority they need to complete the task.
