WBS for Beginners: Break Work into 3 Levels for a Complete Task List

WBS for Beginners walks first-time planners through turning a target deliverable into a three-level work breakdown - major, mid, and minor items - so nothing gets missed in the task list. The whiteboard holds a mind map of the deliverable split into major and mid items, a three-frame sizing guide, a five-step breakdown flow, a five-row WBS table, and a gap-check frame. The task board runs five columns - not split yet, splitting, awaiting estimate, under review, and confirmed - with 4 parent tasks and 12 subtasks, from deciding the deliverable to tabulating the table, all not started. The first question everyone hits is how far to split, and this board's guide is simple: split until one person can finish within a week and someone else can judge whether it's done. Setting the project's purpose and scope is covered by a separate starter template, so this one focuses only on the breakdown once scope is fixed.

Split one more level and ask the owner about the size 1. Write one deliverableName the one thing left at the end, as a noun. e.g. a full new-hire training program. This becomes the center of board 1. 2. Split into major itemsSplit the deliverable into 5-8 chunks and number them 1, 2, 3... Make sure they add back up to the deliverable. e.g. planning, materials, instructor booking - the 8 in board 1. 3. Split into mid itemsSplit each major item into 2-4 parts with branch numbers 1.1, 1.2... e.g. materials -> 2.1 outline / 2.2 slides / 2.3 exercises. 4. Split to minor itemsSplit until it meets the guide in boards 2-4, then stop that branch. Keep the depth to three levels - major, mid, minor. 5. Copy into the tableCopy minor items into board 6 in number order with owner, due date, and estimate (person-days). One row per task. e.g. 2.2.1 draft / Hana / 4/22 / 3 person-days.

Fold duplicates into one. Are the easy-to-forget tasks included?e.g. review and fixes, wait time for approval, printing or shipping, rehearsal. Does every row have an owner and a due date?e.g. if the venue owner isn't set yet, add a row - "decide who by 4/5".
