Right here’s a fast fact. Earlier than writing this text, I found Akin’s laws, which aptly summarize work breakdown constructions. The enjoyable “legislation” reads: It is known as a Work Breakdown Construction as a result of the Work remaining will develop till you have got a Breakdown, until you implement some Construction on it. This legislation is evident and true!
Jokes apart, whereas finding out to amass my venture administration diploma, I discovered an instructive notice within the PMBOK information. The guide, which is a go-to supply for venture managers, warns that “no venture needs to be with no WBS.”
With out a work breakdown construction (WBS), your tasks have a excessive likelihood of exceeding their deadlines and budgets, and never assembly stakeholder expectations. You need none of those.
So, on this information, I’ll lean on my expertise as a venture administration skilled to share what I’ve realized about work breakdown constructions. You’ll additionally get insights from trade specialists who will enable you to study WBS.

What’s a piece breakdown construction?
A piece breakdown construction (WBS) is a visible define of the distinct steps in a venture. These steps manage the whole lot about your venture hierarchically.
In response to Jeffrey Pinto, an writer and professor, the WBS is a planning mechanism for figuring out the interrelationship of assorted actions in a venture. In its easiest kind, the WBS seems to be such as you see within the template beneath:
Components of Work Breakdown Construction
Primarily based on what I realized from Pinto, each WBS has at the very least 4 ranges in project management.
Nonetheless, in case your venture is advanced, you’ll have extra sub-deliverables, and your work package deal will proceed rising.
Listed here are the 4 ranges of a WBS for a easy venture.
|
Stage |
WBS Time period |
Description |
|
Prime-Stage/Stage 1 |
Venture |
The general venture below growth |
|
Stage 2 |
Deliverable |
The main venture elements |
|
Stage 3 |
Sub-deliverable |
Supporting deliverables |
|
Stage 4 (Exercise) |
Work package deal |
Particular person venture actions |
As an instance, I’ll clarify these ranges with the WBS for a advertising convention.
Prime-Stage/Stage 1
The highest degree of the WBS covers the whole venture scope. It’s additionally the ultimate deliverable, which outlines what I wish to accomplish. For this venture, the highest degree is a “advertising convention plan.”
Stage 2
The second degree of the WBS outlines the most important venture elements. It additionally reduces the venture scope into models that function deliverables.
Deliverables embody options for merchandise or phases for duties. My venture is a sequence of eight duties. You’ll discover I numbered every deliverable at this degree (and for the decrease ranges).
It is a deliberate factor, which is absent from some WBS I’ve seen.
Professional tip: Numbering a piece breakdown construction helps with readability, group, and monitoring. With numbering, I’ve a logical and visible method to know the connection between deliverables, sub-deliverables, and work packages. This makes it simple to discover a work factor, particularly for a big venture.
Stage 3
The third degree of the WBS is the sub-deliverable. Every sub-deliverable is a part of the primary deliverable you’ll present to your stakeholders.
When contemplating an merchandise as a sub-deliverable, a consideration is the benefit of managing it. For example, the sub-deliverable, researching potential venues (2.1), suits this invoice.
Why? It’s manageable. I can assign some hours to it. The fee is minimal.
If you happen to’re making your individual WBS, positively use a template to get you began.
Actions
The final degree of the WBS is actions. Consider actions like atoms. They’re the smallest components inside a sub-deliverable or deliverable.
For example, to ship the occasion planning and technique, I might want to execute the next actions:
- 1.1 Outline goals and objectives
- 1.1.1 Conduct a kickoff assembly with stakeholders
- 1.1.2 Draft a listing of measurable objectives
- 1.1.3 Finalize goals in a venture constitution
- 1.2 Establish audience
- 1.2.1 Conduct market analysis
- 1.2.2 Create viewers personas
- 1.2.3 Validate personas with stakeholders
- 1.3 Develop occasion theme and branding
- 1.3.1 Brainstorm theme concepts
- 1.3.2 Design brand and branding supplies
- 1.3.3 Approve theme and branding with stakeholders
- 1.4 Set a funds and allocate assets
- 1.4.1 Establish key expense classes
- 1.4.2 Create an preliminary funds plan
- 1.4.3 Get funds approval from stakeholders
- 1.5 Create venture timeline and milestones
- 1.5.1 Draft an in depth venture schedule
- 1.5.2 Establish key milestones
- 1.5.3 Share the timeline with the group
Advantages of Utilizing WBS in Venture Administration
Whereas studying concerning the WBS, a few of my friends didn’t seem satisfied. Some argued that it’s nice on paper however unapplicable in real-life conditions. For others, its advantages outweigh the flawed pondering of not having one.
So, how does a WBS truly assist?
A WBS prevents scope creep.
Each stakeholder is on the identical web page when there’s a WBS.
With out one, stakeholders can proceed including to the venture till it turns into unmanageable. As soon as this occurs, you’ll must revisit your timelines, milestones, funds estimates, dangers, and so forth. I wouldn’t like this to occur, particularly when dealing with a number of tasks.
Within the waterfall atmosphere characterised by a sequential method to venture execution, the advantages of a WBS in avoiding scope creep might be undebatable.
Nonetheless, in Agile environments with out totally outlined finish merchandise, some specialists argue stakeholders will change their minds on what they need, when, and why.
Whereas this negates the worth of a WBS, one expert argues that Agile groups shouldn’t use the excuse of agile to not plan and danger having scope creep.
“Whereas I get {that a} full waterfall type WBS can be needed in a development venture, they [agile teams] cannot go full no estimates on tasks with inter-team dependencies, multi-fiscal-quarter supply dates, and something greater than 5 group members.”
“At a minimal, all necessities of the tip product needs to be documented, a roadmap of all main deliverables needs to be communicated, they need to be performing some equal of a WBS for the subsequent two weeks of labor and ideally as much as the tip of the subsequent milestone, and a tough define of how the whole lot else goes to return collectively,” they add.
A WBS aids venture funds estimation.
A piece breakdown construction isn’t only a planning instrument — it helps with budgeting. By breaking my venture into detailed actions, the WBS makes it simple to assign budgets.
Price range overruns stay a pervasive subject in venture administration. In a BCG survey of 403 respondents, 49% stated over 30% of their group’s expertise growth tasks exceeded their budgets. Tech tasks use Agile due to the flexibleness and iterative progress it affords.
Whereas I perceive {that a} pre-established funds runs in opposition to the Agile mindset, incorporating a WBS into dash planning helps. Assigning budgets on the dash degree permits groups to stay adaptable whereas sustaining monetary self-discipline.
A WBS captures all work packages.
I’ve discovered that making a WBS forces me to assume critically about each facet of a venture. From main milestones to granular deliverables, every work package deal is accounted for. This not solely helps visualize the scope of the venture but in addition ensures nothing is ignored.
However earlier than penning down each package deal, speaking to stakeholders is significant. Not doing so is one purpose for the current and monumental failure of the Excessive-Pace Rail 2 in the UK.
In response to Tejvan Pettinger, an economist, “[High-Speed Rail 2] dangers being a £50 billion white elephant and a monument to poor planning.”
Pettinger didn’t recommend that the HS2 group didn’t have a complete WBS — nevertheless, he makes a verifiable declare of fixed adjustments to the venture scope.
And as we’ve established, when this occurs, the venture will get derailed on nearly all fronts and the group has to return to the drafting board.
Varieties of WBS in Venture Administration
There are two varieties of WBS:
- Deliverable-based work breakdown construction.
- Section-based work breakdown construction.
Deliverable-Primarily based WBS
A deliverable-based WBS will get tangible outcomes (deliverables) for stakeholders.
What I like about this WBS is its deal with “what to do” over “the right way to do” a activity. As such, this WBS is simple to switch, easy for estimating price, and gives an entire view of the entire work scope.
The deliverable-based WBS has functions in eventualities akin to:
- Initiatives with clear outputs akin to organizing an occasion or developing a constructing.
- Consumer-focused tasks like particular advertising campaigns or design tasks.
- Initiatives requiring detailed scope administration akin to launching a brand new product.
Section-Primarily based WBS
A phase-based WBS organizes work in response to the sequential levels of the venture lifecycle (initiation, planning, execution, monitoring and management, closure). With this WBS, I need to element the method for reaching particular deliverables.
One of many easiest methods to elucidate a phase-base WBS is to contemplate a analysis writing venture. With out doing an ethics evaluate, I can’t interview individuals to get insights for writing my last report.
With the phase-oriented WBS, I just like the clear insights it provides into components that hinder the venture’s progress. This WBS can be nice for offering a roadmap of “when to do” duties, guaranteeing every stage builds logically on the earlier one.
The phase-based WBS is fitted to:
- Course of-driven tasks akin to implementing a enterprise system or conducting analysis and growth.
- Standardized lifecycle tasks like these following Waterfall methodology.
- Lengthy-term tasks with sequential development, akin to multi-year infrastructure builds or strategic planning initiatives.
Learn how to Use a WBS for Managing Initiatives
A WBS is superb for chopping advanced tasks into the smallest bits. However past its core perform of visualizing the venture scope, right here’s the right way to use a WBS:
1. Assign tasks.
The WBS makes it simple to assign deliverables or duties to group members. This helps everybody know what they’re chargeable for and retains issues from getting duplicated.
2. Estimate time and assets.
I take advantage of the WBS to determine how lengthy every activity will take and what assets are wanted. This makes it simpler to create a practical schedule and funds.
3. Facilitate communication.
The WBS is an effective way to maintain everybody on the identical web page. It helps align group members and stakeholders on the venture’s scope, tasks, and timelines.
4. Handle dangers.
I search for potential dangers in every WBS factor and create plans to deal with them earlier than they disrupt the venture.
5. Combine with venture administration instruments.
I’m a fan of instruments like Trello and Asana. Inputting everything of my WBS into these instruments makes it simple to assist preserve monitor of duties, handle assets, and generate stories.
Remaining Ideas
The work breakdown construction is a cornerstone that gives readability on tasks.
Whereas I had realized about WBS throughout my research and utilized it in my skilled life, diving into its nuances and reflecting on its use in real-world eventualities gave me a renewed perspective.
The WBS is crucial not only for planning and organizing a venture, however for figuring out dangers and sustaining management over scope and budgeting.
A helpful studying for me was the controversy concerning the relevance of WBS in Agile. A product backlog in Agile tasks is sort of a WBS, the place epics or options are managed in sprints.
With out placing thought into the work objects, whether or not in Agile or Waterfall, the venture is heading for the rocks.
Backside line: Profitable tasks begin with a well-thought-out plan, and that plan begins with a piece breakdown construction.
Unsure in the event you choose to embed a desk or simply use a screenshot so I gave you each choices for these 3 cases (particularly as a result of the third is LARGE)
