Project Planning, Part 3 – A Work Breakdown Structure

The work breakdown structure (WBS) is part of the project management plan.  It is a detailed outline of the tasks and subtasks you will later complete as your team executes and controls the project.  The WBS should conceptually align with the project charter and with additional information from any proposals that were created.  It is the basis for subsequent steps in project planning (scheduling, manpower and cost estimating, avoiding capacity bottlenecks).

The Work Breakdown Structure

Whether or not you use project software, you should load all elements of the WBS into your company accounting software.  It is exceedingly difficult to manage (or later improve) what you can’t measure, and your customer may want to know expenditures by element before paying your invoice.  In terms of the graded approach, don’t overcomplicate the WBS.  Only create subtasks that have real meaning.  If the work item only takes a few hours to accomplish, or if it would look silly as a separate line item on a status report or invoice, then it is too detailed to show up in the WBS (but do include all such items in checklists to ensure your detailed resource planning, schedules, and quality plans are accurate).

The WBS tasks and subtasks can be organized by phases, by type of activity, or some combination thereof.  Below is an example of a WBS for a project that will purchase and install an entirely new computer system for a 100-person office.  Not being an information technology professional, I would call this a draft, and ask a real IT professional for comments.

WBS in a Flowchart or Tree Format

Some people react better to a flowchart representation, plus it is better at showing loops and branches, if there are any.
