A budget says how much. It does not say when, in what order, or who. Design work rarely fails on effort — it fails on information handoffs. 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 ReferenceModule 6 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
Open most design schedules and you find a Gantt chart full of dates — bars that say when each task is “supposed” to happen. But a row of dates is not a plan. When a design project slips, it is almost never because someone was lazy. It is because someone was waiting on information that no one sequenced to arrive: the architect couldn’t place the floor plan because mechanical hadn’t sized the equipment, because the owner hadn’t chosen a system.
Think of a patient moving through a hospital. The journey is a series of handoffs — intake to triage to imaging to surgery — and a delay anywhere stalls everything after it. A design project is the same: the project is the patient, the disciplines are the caregivers, and what moves between them is information. Plan the handoffs and the schedule takes care of itself.
Design work flows on information, not effort. Sequence the information, and the work follows.
That is Logic-Based Planning: instead of guessing dates forward, you start from the deliverable and work 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?
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 — how money will be spent over the life of the project.
Constraint · the fee availableThe completion of work — 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 availableModule 6 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 — with 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 — planning is a process, not a one-time event.
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. You start at the end — the deliverable that must be true at, say, 30% Design Development — and ask 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. Chain those handoffs and you have built 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’ll 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 because 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. Plan it forward and you’d never see that. Pull it backward and it’s obvious.
?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?
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 — the project’s nervous system 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 — drop the finished week, confirm the next, add one new week. It keeps the milestone board decluttered while every discipline still sees the whole.
The last question · Who?
The schedule tells you when; the soft-resource plan from Module 6 tells you which role. Lay one over the other and you get a resource heatmap — how many hours of each role the project needs, week by week. That demand is abstract until you hard-schedule it: assign real people, and check that the person you need isn’t 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 |
Now combine all of it — the work, the hours, the schedule — into one instrument the PM lives by: 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 lets you answer, every week, the Module 3 question: are we earning value as fast as we’re spending effort?
The close
A pull plan, a swim-lane board, and an Earned Value Plan are not documents you build once and file. 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 — that is how a budget becomes a delivered project.
With Modules 6 and 7, planning is complete: the work is broken down, priced, sequenced, and staffed, with a roadmap to measure it against. Everything in Managing Execution is the act of holding the team to this plan — and adjusting it honestly when reality pushes back.
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 gates 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?
Module 6 throughline
Design work flows on information, not effort. Plan it in reverse, make the handoffs visible, and staff the flow — and the schedule keeps itself.
