Making a Work Breakdown Construction


In terms of managing Waterfall initiatives, probably the most necessary first steps is figuring out scope—what’s in and what’s out for the mission. This important data is often outlined in a mission scope assertion that names the mission’s main deliverables and exclusions. A well-crafted mission assertion could seem enough to determine the scope—and it may be. But I can attest to the unimaginable worth of going one step additional and creating a piece breakdown construction (WBS). It’s a step that’s too typically skipped.

The WBS is a visible mission administration device that does precisely what the title implies: subdivides the product and corresponding initiatives into distinct increments of labor. As a result of our brains wish to work visually, the WBS turns into an efficient approach for the group to conceptualize its work.

Typically talking, scope is pushed by necessities elicited from the client or sponsor. A sponsor could method a mission supervisor with the preliminary parameters for a new product, resembling a line of laptops that the corporate will promote in North America. From there, the mission supervisor or enterprise analyst derives a sequence of necessities, asking questions like, “What colours will the laptops be?” “What’s the exhausting drive’s imply time between failures?” “What number of USB ports are wanted?” It’s necessary to keep in mind that, on this context, the scope contains something contributing to the mission’s end result. This implies not solely product scope (the options and features of the laptop computer) but in addition mission scope (the work required to ship these outcomes). The mission scope may entail duties like lining up manufacturing for the laptop computer or allocating assets for mission administration.

Exclusions are essential to file within the scope assertion in order that later nobody asks one thing like, “Why aren’t we transport to the UK?” As soon as authorised, this scope baseline helps stop scope creep, which happens when somebody provides extra work with out contemplating its affect on schedule, prices, dangers, and assets. Any group member can verify the scope assertion and see that every one the decision-makers signed off on which markets to prioritize, though in my expertise, many individuals by no means really learn the scope assertion.

That’s the place the WBS is available in. When the group invests the time to develop a WBS collectively, it supplies a possibility for everybody to visualise and interpret everything of the scope—what’s in and what’s out—together with associated points resembling budgets and timelines. As such, I like to think about the WBS as a mission’s Rosetta stone.

What Is a Work Breakdown Construction?

The WBS was developed by the US Division of Protection within the Fifties and remains to be generally utilized by authorities groups and contractors, on condition that mission outcomes in these contexts are sometimes decided on the outset. The WBS will also be precious in different conditions the place Waterfall is required, which is extra frequent than many mission professionals could understand. Regardless of the ascendancy of Agile methodologies, which don’t embody the WBS as a part of the usual toolkit, 39% of data know-how initiatives nonetheless make use of Waterfall, in keeping with the Challenge Administration Institute (PMI). In different industries, the odds are even greater.

The WBS breaks the mission scope into progressively smaller increments. This hierarchical rendering can seem in tabular or record codecs, however the commonest (and helpful) format resembles a household tree, with associated work grouped on completely different branches.

A work breakdown structure example divides a tech project into eight phases (e.g., deployment) and then into smaller tasks (e.g., technical release).
This WBS instance subdivides work for a software program improvement mission into three or 4 ranges, organized in keeping with phases.

The primary stage of the WBS identifies the mission. The second stage divides the mission into phases, deliverables, or features. The selection relies upon fully on group preferences, however I desire phases as a result of they extra readily align with Waterfall’s sequenced method. The following layers are then subdivided till reaching an increment referred to as a work bundle. Typically, work packages require not more than two weeks (80 hours) to finish, however that isn’t inviolate. In giant authorities or aerospace initiatives, for instance, a piece bundle could take a number of hundred hours. I’ve not often seen a WBS drill down greater than 4 or 5 ranges. By then, the group ought to have enough data to know what work must be performed.

Typically a WBS will incorporate a specialised numbering scheme that echoes the hierarchical breakdown. Essentially the most fundamental kind assigns a quantity to every merchandise within the second stage of the WBS (e.g., 1, 2, 3). Subsequent layers in every column are additional divided with decimal factors (e.g., 1.1, 1.2, 1.3; 1.1.1, 1.1.2, 1.1.3). In my expertise, groups can obtain the planning advantages of the WBS with out the numbering scheme, however in authorities initiatives, it’s sometimes a requirement.

It’s essential to notice that even when a group organizes a WBS in keeping with phases or features within the second layer, the WBS remains to be a “what” doc, not a “who” or “when” doc. It ought to seize everything of the work that should happen (typically referred to as the 100% rule) however not who does it or when. Nonetheless, as soon as the group has created a WBS to outline what work should happen, everybody can extra simply speak about these associated issues.

So the place does the Rosetta stone a part of this are available? The WBS is a visible reference that permits group members to align on a shared understanding of product and mission scope. It additionally helps the group start to make sense of different points, like prices, dangers, assets, and schedules. As PMI eloquently places it in its Apply Commonplace for Work Breakdown Constructions (a superb useful resource for anybody who needs to know the main points of this device): “The WBS creates a standard language amongst all mission stakeholders, together with mission administration and subject-matter facets.” In my expertise, that is undoubtedly the case.

How you can Create a Work Breakdown Construction

Ideally, WBS planning shouldn’t be a solitary exercise {that a} mission supervisor undertakes alone. It’s higher to develop the WBS with representatives of all of the groups concerned. This collaborative method is how the frequent language comes into being. Relying on the dimensions of the mission, one WBS could also be sufficient, though in some circumstances, every group could need to make its personal WBS.

As a guide, I’ve led mission kickoff occasions for quite a few organizations, together with world pharmaceutical corporations, for which I co-facilitated in depth two-day working periods to plan new drug improvement initiatives. The drug improvement course of can take 10 to fifteen years, however the scope is outlined firstly. Stakeholders would attend from far-flung corners of the globe to satisfy and higher perceive the product they’d finally be producing. When performed correctly, periods like this additionally function a superb team-building train. I ought to emphasize that the individual main this train needs to be an skilled facilitator.

Amongst different issues, my co-facilitator and I’d train attendees easy methods to craft and use a WBS. Representatives from every division—regulatory, advertising and marketing, manufacturing, gross sales, and so forth—would produce their very own WBS by making use of sticky notes to flip charts on the partitions of a big convention room. (For distant conferences, Miro is a superb device for the same exercise.) Groups can develop the WBS by following a top-down or bottom-up method: Within the first state of affairs, a group arranges sticky notes that title bigger work objects after which provides sticky notes representing subtasks. Within the second state of affairs, the subtasks are organized first. Crew preferences dictate which method works finest, however I’ve all the time discovered top-down simpler to examine.

Five WBS tips: Capture 100% of project scope; focus on “what,” not “who” or “when”; build it as a team; ensure subtasks add up; limit to five levels.

Every group aimed to map out everything of its scope. If that stage of element wasn’t attainable (as a result of a key consultant couldn’t attend or for another motive), the group would nonetheless embody a planning bundle for these objects on the WBS and elaborate upon them later. The group brainstorming allowed the groups to visualise the complete contours of the proposed work. You may think about the energetic debates that ensued. Individuals would say issues like, “Is that this actually what we’re doing?” or “That doesn’t belong right here; it belongs there.” On the finish of the two-day periods, every group had produced its personal WBS, and we had a visible image of the mission. The sponsor may look across the room and say, “Sure, there’s my product,” or “The place is the advertising and marketing requirement we mentioned?” By way of these discussions, the group understood the character of its work in better element.

Whereas the attendees had been mapping out their work, my colleague and I’d enter the duties right into a scheduler like Microsoft Challenge or Smartsheet. Then we centered on linking the objects to supply an preliminary timeline for all the mission. The scope could require official approval and sign-off from the sponsor and different stakeholders, so the schedule created through the assembly is barely a tough draft. Nonetheless, the schedule illustrates how a WBS has nearly instantaneous utility, permitting groups to start making ready for the subsequent mission steps. In the actual world, groups typically skip WBS planning and soar on to constructing a schedule, forcing them to consider “what” and “when” concurrently. In my expertise, the WBS supplies a precious alternative to element what goes into the scope first, earlier than figuring out when the work must happen.

It’s necessary to notice that specialised instruments will help mission managers develop a WBS. One is named WBS Schedule Professional, and it integrates seamlessly with Microsoft Challenge. If a mission supervisor can not carry all the group collectively, both in individual or just about, I nonetheless encourage mission managers to draft a WBS on their very own, maybe utilizing a specialised device. The mission supervisor can current this draft to the group at a gathering. The draft could get some issues unsuitable, however consider me, the group shall be glad to appropriate these points. That’s an excellent factor.

For the file, I additionally requested ChatGPT to generate a WBS for me, and it did so in a bulleted format. The final breakdown was surprisingly good. With cautious prompting, I believe mission managers may flip to generative AI instruments for useful brainstorming help and even coax a picture generator resembling Dall-E 3 to render a graphical WBS. After all, the outcomes would require double-checking for accuracy.

Different Outcomes of WBS Planning

Whereas the WBS could seem to be “merely” a scope device, it gives rather more than that. Challenge managers should concern themselves not solely with scope but in addition with prices, dangers, assets, stakeholders, and any variety of points. If a part of the scope is lacking, this implies there are:

  • No assets related to it.
  • No schedule allowed for it.
  • No dangers recognized for it.
  • No stakeholders specified.
  • No assumptions made about it.

These points don’t go on the WBS, but when the group is already assembled in a big convention room for WBS planning—or collaborating just about utilizing a device like Miro—it presents a superb alternative to start addressing them. In truth, I preserve that there isn’t a higher time to do that, on condition that the mission supervisor already has the proper folks in the proper place on the proper time. The group can have a look at the fleshed-out WBS and say, “How many individuals do I want for this mission?” or “What are the dangers concerned?” And the sponsor could sigh and ask, “How a lot will all this price?”

Utilizing flip charts or on-line whiteboards, the group can begin to file dangers, assets, and motion objects in what we name parking tons. (The federal government formally defines the relationships between these associated issues utilizing a doc referred to as a work breakdown construction dictionary. Nonetheless, I’ve by no means encountered a group that makes use of this dictionary in nongovernment contexts.)

Does the WBS Work in Agile?

An Agilist studying this would possibly say, “All of this sounds nice, however can we use this?” Strictly talking, the reply is sure—PMI’s Apply Commonplace for Work Breakdown Constructions even features a part on utilizing the WBS in Agile. But I wouldn’t suggest it, on condition that one of many most important variations between conventional mission administration and Agile is how scope is dealt with.

We sometimes use Waterfall after we—or the client or sponsor—have a really clear thought of what we wish as an finish end result, end result, or product. Change is permissible however requires a considerably laborious change management course of. In Agile, the top end result will not be as well-defined, permitting the sponsor or product proprietor the posh of adjusting their thoughts because the mission evolves. This implies the scope may change from dash to dash—sometimes solely per week or two in length—so time spent creating the WBS would distract the group from the worth they need to give attention to delivering.

Higher Planning Means Higher Initiatives

The method of making a WBS could sound time-consuming, and it may be, particularly if a mission supervisor doesn’t have all of the stakeholders within the planning session or the necessities usually are not effectively understood. With sufficient upfront preparation, nevertheless, making a WBS as a group could be a little bit of a miracle. It brings everybody collectively, enforces planning, sparks dialog, and results in documented discussions about who, what, when, and the place. These outcomes will save time in the long term.

I’ve carried out a couple of dozen of the two-day planning workshops I described earlier, and we by no means failed to finish with an excellent total sense of the mission. If I’m managing a Waterfall mission, I’ll use the WBS every time attainable, even when I can’t pull the group collectively for 2 days. The WBS is prime to planning, and, put merely, higher planning results in higher execution.
