Filter Weekly Work Plans from the Pull Plan (Not Brand-New Creations)

Here’s a workflow problem that’s costing your project hours of wasted effort every single week: trades are creating lookahead plans and weekly work plans from scratch when they should be filtering them from the pull plan. This isn’t a minor inefficiency. It’s systemic waste disguised as collaboration. And most teams don’t even realize they’re doing it wrong.

Let me paint you a story.

The CPM Nightmare: A Field Story That Shows the Waste

Our company and a team of us were working with a massive contractor on a massive mega project. And their CPM scheduling requirements said, and I’m not exaggerating, that you had to have a CPM baseline. You had to keep the CPM schedule up to date all the time. When you did the pull plan, you then looped that pull plan detail back into the CPM, but you had to do it under hammock activities and match it to the original zoning so that you could do your baseline comparison and do your monthly updates.

And then once the pull plan was done, trade partners were to create lookahead plans from scratch. The schedulers would take an incredible amount of time to update the CPM schedule. Then when the weekly work plan hit, the scheduling team said the trade partners had to create their weekly work plan from whole cloth again, which the schedulers would then upload and input into the CPM schedule in a perverted form to match the original baseline.

And then the scheduling team, and I’m not making fun of them, they’re in a bad system, they would create filters for the weekly work plan in black and white filters with lots of text and issue it to the trades by email in a format that they didn’t use, follow, or understand. There’s so much waste in that. It’s completely disconnected.

And then contractors will say, “This is not working. We need to implement Takt.”

The Failure Pattern: CPM Fighting Takt

Here’s what happens when you try to merge CPM and Takt without understanding the fundamental difference. The lookahead and the weekly work plan are filters from the production plan that came from the pull plan. But when you try to merge CPM and Takt, the schedulers will go back and say, “Yeah, but I want you to actually get that from the trades and update, get that from the trades and update.”

No. When you do that, now you’re not vertically aligned to the milestones, and we don’t have trade flow, and it’s detrimental. CPM and Takt are fighting. You either have to switch all the way over to a Takt and Last Planner System, or you have to understand that the lookahead plan and the weekly work plan are filters. They’re not brand-new creations.

The system failed them; they didn’t fail the system. The schedulers were trapped in a CPM framework that demanded waste. The trades were doing triple work: pull planning, creating lookaheads from scratch, then creating weekly work plans from scratch. And nobody stopped to ask why they were recreating information that already existed in the pull plan.

What You’re Maintaining When You Filter Properly

Let me show you visually what happens when you do this correctly. When you’re dealing with a master schedule in the right format, it’s in a time-by-location format, and you have identified your milestone. When you do your pull plan to this milestone and you have coordinated a sequence, you’ve actually done your pull plan with different zones. And you have now, from your original macro-level phase, optimized that without removing any durations for the trades. Then you’re able to filter out your next six weeks and your next week.

There are a couple of things that you’re maintaining. Not only are you maintaining your proper milestone, which means that you’re vertically aligned, but you’re also able to gain buffers, and you’re maintaining diagonal trade flow. So, by the time you get to the lookahead and the weekly work plan and you’ve filtered this thing out, these two have vertical milestone alignment, and they have diagonal trade flow. And that’s crucial.

Here’s why this matters. Vertical milestone alignment means your short-interval plans connect back to the master schedule commitments. The owner knows when you’ll finish. The team knows the target. The sequence supports the promise. Diagonal trade flow means the trades move through zones in rhythm. One trade finishes, the next trade enters. No stacking. No waiting. No chaos.

When you filter from the pull plan, you preserve both. When you create from scratch, you lose both.

The CPM Way: Layer After Layer of Waste

Now let me show you what happens when you don’t do it this way. If you do it the CPM way, let’s go through this nonsense. Let’s say that we’re dealing with just one phase and your CPM network in your work breakdown structure has created the milestone for that phase. Not only is this milestone likely too far forward because it doesn’t have buffers and it doesn’t have trade flow, but then when you go to pull plan to it, they’ll only typically do one, which is large batch.

You’re wasting an incredible amount of time. That typically means the super and the scheduler start dissolving logic at the end. And that also means that your new sequences that update the CPM do not have the right zoning and do not gain buffers. And actually now you have dissolved logic. And then when you actually filter out for your lookahead plan and your weekly work plan, it will not have trade flow and it will not have vertical alignment to the milestones. It will be past.

So, whatever you end up with is going to be a problem. Typically, instead of filtering it down, what will happen is not only did the trades do the pull plan, which educates the CPM, but now the CPM schedule asks trades to create this brand new lookahead, and the weekly work plan brand new. This is all added work.

Let me name the problems clearly:

• You have an incorrect milestone to start
• You’re already dissolving logic to make the CPM fit reality
• You have a large batch pull plan that doesn’t optimize zones
• You are wasting the trades’ time in incredible ways by asking them to recreate information
• You have dissolved logic and you’re past your milestone, which means you’re already overburdening and extending the team
• Your lookahead and your weekly work plans are not correct

This is wasteful and disrespectful. And people think lookahead and weekly work plan are brand new creations. No, they are not.

The Right Way: Pull Plan, Then Filter

Here’s the proper workflow. The pull plan is where you involve the trade partners and where you get your collaboration. The lookahead is a filter from the pull plan. The weekly work plan is a filter from the lookahead. And yes, you can modify things and move them around, but you maintain the structure as a filter, which means that you have vertical alignment, which is important to schedulers, and diagonal trade flow, which is important to production and people.

This is the way to do it. Your lookahead and weekly work plans are filters. Not brand-new creations. Filters. You pull from the master schedule to create milestones. You pull plan to the milestones with the trades. You filter the pull plan to create the lookahead. You filter the lookahead to create the weekly work plan. Each step preserves the alignment and the flow.

And in this system, you’ve got multiple opportunities for the trades to collaborate. The master schedule. The pull plan. The lookahead. The weekly work plan. The day plan. Five different levels. But we never waste their time by asking them to recreate what already exists.

Why This Protects Trade Partners

Behind every scheduling concept is a human being. When you ask trades to create lookaheads from scratch, you’re stealing their time. When you ask them to create weekly work plans from scratch, you’re disrespecting their effort. They already collaborated in the pull plan. They already sequenced the work. They already committed to the flow. Now you’re asking them to do it again in a different format for a different system that doesn’t align with the first one.

That’s not collaboration. That’s waste. And the trades know it. They stop trusting the system. They stop engaging. They show up to meetings and go through the motions because they’ve learned that their input gets filtered through a CPM framework that dissolves their logic and ignores their sequence.

When you filter properly, you respect their time. You honor their collaboration. You preserve their flow. And you give them confidence that the plan they helped build is the plan the project will follow.

Connecting This to Takt Steering and Control

The book Takt Steering and Control describes exactly how to do this. It shows you how to structure the master schedule in time-by-location format. It shows you how to pull plan to milestones with proper zoning. It shows you how to filter lookaheads and weekly work plans so you maintain vertical alignment and diagonal trade flow. And it shows you how to avoid the CPM trap of dissolving logic and overburdening the team.

This is one of the ten improvements to the Last Planner System. It’s also directly connected to the ten myths of CPM. You’ll learn more about Lean and scheduling in The 10 Myths of CPM than almost any other book. The content is professional, the editing is sharp, and the concepts are field-tested. If your project needs superintendent coaching, project support, or leadership development, Elevate Construction can help your field teams stabilize, schedule, and flow.

A Challenge for Schedulers and Superintendents

Here’s what I want you to do this week. Walk through your current workflow. Are you asking trades to create lookaheads from scratch after they’ve already done the pull plan? Are you asking them to create weekly work plans from scratch after they’ve already created the lookahead? If the answer is yes, you’re wasting time and disrespecting your partners.

Change the workflow. Filter the lookahead from the pull plan. Filter the weekly work plan from the lookahead. Preserve the vertical alignment. Preserve the diagonal trade flow. And watch what happens. The trades will engage more deeply because their work isn’t being thrown away. The schedule will stabilize because you’re not fighting your own logic. And the project will flow because the short-interval plans connect back to the master schedule.

One last time: lookaheads and weekly work plans are filters. They are not brand-new creations. Yes, you can adjust them. But you maintain the structure as a filter so you preserve alignment and flow. As we say at Elevate, respect for people starts with respect for their time. Stop asking trades to recreate what already exists. Filter from the pull plan and protect the flow.

On we go.

Frequently Asked Questions

What does it mean to filter a lookahead from the pull plan?

It means you take the pull plan sequence and extract the next six weeks as your lookahead. You’re not creating a new plan from scratch. You’re pulling a subset of the existing plan and refining it for short-interval coordination.

Why does CPM scheduling fight with Takt planning?

CPM pushes toward milestones using logic networks and often dissolves that logic when reality doesn’t match. Takt pulls toward milestones using trade flow and buffers. When you try to merge them without understanding the difference, you lose vertical alignment and diagonal trade flow.

Can you modify the lookahead and weekly work plan after filtering?

Yes. You can adjust for changes, delays, or new information. But you maintain the structure as a filter so you preserve the alignment to milestones and the flow between trades. You’re refining, not recreating.

How many collaboration opportunities should trades have in the planning system?

Five levels: master schedule, pull plan, lookahead, weekly work plan, and day plan. Each level is a filter from the previous one, which preserves alignment and flow while giving trades multiple touchpoints to coordinate and commit.

What happens if we keep creating lookaheads and weekly work plans from scratch?

You waste trade time, dissolve logic, lose vertical alignment to milestones, lose diagonal trade flow, and create disconnected schedules that nobody trusts. The trades disengage because their collaboration in the pull plan gets ignored in the short-interval plans.
