A budget says how much the work costs. A schedule must still answer when the work happens, in what order, and who performs it. Design work fails on information handoffs far more often than on effort, and Logic-Based Planning sequences the work so the right information reaches the right person at the right time.
Illustrated module guide · the complete walkthrough · companion to the Quick ReferencePart A broke the work down, soft-resourced it, and priced it. Before you can sequence or staff anything, what two products of that module must already be in hand?
The problem
Most design schedules open as a Gantt chart full of dates, bars that say when each task is “supposed” to happen. A row of dates records intention rather than the logic that connects the work. When a design project slips, the cause is almost always that someone was waiting on information that no one sequenced to arrive. The architect could not place the floor plan until mechanical sized the equipment, and mechanical could not size the equipment until the owner chose a system.
Consider a patient moving through a hospital, where the journey is a series of handoffs, from intake to triage to imaging to surgery, and a delay anywhere stalls everything after it. A design project carries the same shape: the project is the patient, the disciplines are the caregivers, and what moves between them is information. Sequencing the handoffs is therefore what produces a schedule that holds.
Design work flows on information, not effort. Sequence the information, and the work follows.
That is Logic-Based Planning: rather than guessing dates forward, a project manager starts from the deliverable and works backward, sequencing the flow of information so every task has what it needs the moment it needs it.
?Pause & predict.
A PM builds a Gantt chart, assigns every task a start date, and emails it out. Two weeks in, structural is idle. Nobody missed a date. What did the Gantt chart fail to capture?
Planning Studio 2 opens with the plan you committed in Part A, your WBS, your hours, and your margin, and walks it through everything this module teaches: milestones, protected QAQC periods, a backward-built network, the Gantt, the Earned Value Plan with its labor demand, and the S-curve. If you have not finished Studio 1, the tool sends you back, or hands you the plan Grace filed in BST. Open Planning Studio 2 →
The frame
Every project plan is really three plans at once, and the PM’s job is to keep them in balance. Each one carries a constraint, and good planning focuses effort on releasing the binding constraint while keeping the team moving toward the goal.
The budget and cash flow, the pattern of how money will be spent over the life of the project.
Constraint · the fee availableThe completion of work, both what work will be done and when it will be done.
Constraint · the work to be doneHow the project will be staffed, the relative labor demand across the schedule.
Constraint · the people availablePart A built the financial plan (the budget) on top of the task plan (the WBS). This module adds the schedule to the task plan and then lays the resource plan over both. The art is sequencing the work so the binding constraint, usually a piece of information or a single over-booked person, is released before it stalls the team.
The method
Logic-Based Planning (LBP) ensures design teams work to the logical flow of information between disciplines. It runs in five frameworks, sequenced from the whole phase down to this week’s work, each one keeping the team aligned to the deliverables that matter.
Set the overall phase schedule and define what “done” means for each deliverable, using a Deliverable or QA checklist.
Find the checkpoints inside a phase (30 / 60 / 90%). Separate deliverables from information, list each discipline’s needs and provides, and reverse-sequence to the critical path.
Each discipline plans its own parallel work in rolling two-week increments, aligned to the milestone plan.
Move the right information between disciplines on time, so no one stalls waiting.
Revisit and adjust the plan on a regular cadence, since planning is a continuing process.
Visualize the flow of work so the team is prepared to complete the right work, with the right people, at the right time, at the optimal cost, and efficiently advance the project.
The core skill
Pull Planning builds the schedule backward from a milestone rather than forward from a start date. A project manager starts at the end, the deliverable that must be true at, say, 30% Design Development, and asks one question over and over: “What is needed immediately before this, in order to deliver it?” Each answer is a handoff: one discipline needs something, and once they get it they provide something to the next, in a stated duration. Those chained handoffs are the critical path of information.
The discipline is to separate deliverables from information, and to phrase every link the same way: “In order for me to provide X, I need Y. Once I have it, I will provide X in N days.” Step back through an Oakhaven 30% DD milestone and watch the chain assemble and the start date reveal itself:
Working backward, the chain reveals that the owner’s system selection is the true start of this milestone, and since the owner needs a review window, the initiating act is the PM putting three system options in front of the owner about three weeks before the deadline. Forward planning never surfaces that decision, and backward planning puts it first.
?Pause & predict.
The pull plan shows the owner must pick a mechanical system 3 weeks before 30% DD. The owner is “not ready.” What does the Accountable Owner do?
Reverse planning stops being abstract in Segment 3a: submission is contractual at Week 13, the QAQC weeks are already reserved, and you sequence 13 production packages backward by asking what must exist first. The checker knows the prerequisite network and your milestone deadlines, so placing plan development too late makes it name the week the phase breaks. Set the 50% progress set before Week 6 and it proves the promise cannot be kept, since four weeks of floor plans plus a QAQC week do not fit. Finding that now rather than in December is the point. Work Segment 3a →
Make it visible
The critical path of needs and provides is best drawn as a swim-lane diagram: one lane per discipline, time across the top, and the information handoffs flowing between lanes. It shows who initiates each handoff, who receives it, and when each handoff is due, all on one page.
The swim-lane plan deliberately shows only the shared, critical handoffs, the items with the greatest impact on the whole team. The parallel work inside each discipline lives in a Biweekly Work Plan: each group pulls its own tasks back from its milestone commitments and plans in a rolling two-week look-ahead. Each group drops the finished week, confirms the next, and adds one new week. That rhythm keeps the milestone board clear while every discipline still sees the whole.
When your network holds and you lock the schedule, the Studio re-sorts it into the Gantt: first-to-start on top, last-to-finish at the bottom, QAQC weeks hatched, milestone weeks flagged. Same data and zero edits, and the sequence logic becomes a wall schedule. Adjust the network and the board re-sorts itself.
The last question · Who?
The schedule tells the team when, and the soft-resource plan from Module 5 tells the team which role. Laying one over the other produces a resource heatmap, a count of how many hours of each role the project needs, week by week. That demand stays abstract until the team moves to hard-schedule it: assign real people, and confirm that the person required is not already booked solid elsewhere.
| Role demand | Wk 1 | Wk 2 | Wk 3 | Wk 4 | Wk 5 | Wk 6 |
|---|---|---|---|---|---|---|
| Senior Architect | 40 | 28 | 8 | |||
| Architect | 10 | 30 | 38 | 30 | 18 | |
| Project Manager | 6 | 14 | 16 | 26 | 34 | 16 |
| Principal (QA) | 4 | 6 | 12 | 22 |
The work, the hours, and the schedule combine into the one instrument the PM works from every week, the Earned Value Plan. A Gantt of the sequenced work, weighted by each task’s share of the fee, produces a curve of how much of the fee should be earned by each point in time. It is the roadmap that answers, every week, the Module 3 question: is the team earning value as fast as it is spending effort?
This is where the Studio closes the loop. The EV Plan spreads your $280,000 across your schedule, and the labor demand table converts it to hours per role per week, so with the filed plan both designers run 48 to 53 hours through Weeks 9 to 11. A plan that needs 1.3 designers per seat is a plan no roster can staff. One click, Redistribute labor and maintain performance, moves the overage to the Project Architects at cost parity: same dollars, same weeks, margin untouched, and everyone under 40. Then the S-curve draws, the line you manage to, with your milestones on it. Work Stages 4 to 5 →
The close
A pull plan, a swim-lane board, and an Earned Value Plan are working documents that the team maintains through the phase. The whole point of Logic-Based Planning is that it stays alive: the team revisits the milestone plan and its biweekly work plans on a regular cadence, adjusting as information arrives and constraints shift. The Accountable Owner owns that rhythm, appointing a keeper of the plan, distributing it, and protecting the review.
Sequence the information, staff the flow, and keep the plan current, and a budget becomes a delivered project.
With Module 5, planning is complete: the work is broken down, priced, sequenced, and staffed, with a roadmap to measure it against. Next comes Communication Planning, deciding how the team, the consultants, and the client will stay aligned around this plan, and then the kickoff, where both plans are presented to the project team.
Take one upcoming milestone on a live project. Pull-plan it backward: pick one deliverable, ask “what is needed immediately before this?”, and keep pulling until you reach the first decision that governs everything. Put a date on that decision, and protect it.
?Challenge · from memory.
From memory: does Pull Planning sequence dates or information? And what is the one question you repeat as you pull backward?

Design work flows on information, not effort. Plan it in reverse, make the handoffs visible, and staff the flow, and the schedule holds.
The Studio ends the way real phases begin: your plan rendered on BST screens, covering WBS and fee allocation, the resource plan, and the EV baseline, so the plan lives in the system of record rather than in a workshop file. Load it, post it, then run the cadence this section describes: earned vs. planned, cost vs. earned, every reporting period. See your plan in BST →
