When a crew isn’t meeting deadlines or rework keeps piling up, it’s tempting to look at personalities or motivation. But more often than not, the real issue isn’t people—it’s process.

Three core Lean concepts—waste identification, flow vs. batching, and pull vs. push systems—can transform a reactive, chaotic crew into a well-oiled operation. These aren’t corporate buzzwords—they’re practical tools that reduce stress, improve efficiency, and build accountability on any job site. Whether you run a design/build firm, a landscaping business, or a remodeling crew, these principles apply across the board.

Waste Identification: What’s Stealing Time and Money?

Lean thinking starts with one powerful mindset: eliminate anything that doesn’t add value.

In construction and the trades, that means looking closely at how your team spends their time, how materials move through the job, and where breakdowns happen. Lean defines eight common types of waste—and most crews experience at least five or six of them daily.

The 8 Wastes of Lean (Applied to the Job Site):

1. Defects – This includes rework, callbacks, and punch list items. They usually stem from unclear specs, rushed work, or missing checkpoints.
2. Overproduction – Building more than what’s needed or getting ahead of schedule in a way that creates bottlenecks.
3. Waiting – Downtime due to material delays, unclear instructions, or waiting for someone else to finish their part.
4. Non-utilized talent – Skilled team members doing basic tasks because they haven’t been trained or trusted with more.
5. Transportation – Extra trips to the truck, shop, or supplier because the job site isn’t set up for efficiency.
6. Inventory – Excess material on-site that isn’t being used right away, increasing the risk of damage, theft, or clutter.
7. Motion – Unnecessary walking, bending, reaching, or climbing caused by poor layout or lack of organization.
8. Extra processing – Doing more work than needed, like sanding something twice, duplicating paperwork, or triple-checking work due to lack of trust.

Practical Example:

Let’s say your landscape crew is installing a hardscape patio. If a team member walks back to the truck every 10 minutes for a tool, that’s motion. If pavers are set incorrectly and need to be relaid, that’s a defect. If you ordered double the base gravel “just in case,” that’s inventory. These all cost time, money, and morale.

Quick Fix: Do a daily walkthrough and ask: Where are we losing time? Who’s waiting? What’s getting redone? These are your first clues.

Flow vs. Batching: Why One-at-a-Time Wins the Race

Most contractors batch work by default. Cut all the trim. Then hang all the doors. Then install all the hardware. It feels efficient, but it can actually slow you down and create more errors.

Flow means completing one small section or unit from start to finish before moving to the next. In Lean terms, this is “single-piece flow,” and it creates a steady rhythm of work with fewer handoffs and delays.

Why Flow Works:

• Problems show up sooner and are easier to fix.

• Fewer bottlenecks and idle time between steps.

• Teams stay engaged and coordinated.

• You reduce the need for staging, sorting, and moving materials multiple times.

Batching Breaks Things:

Batching may look neat on paper, but it often leads to:

• Pile-ups of incomplete work

• Long lag times between steps

• Missed quality issues until it’s too late

• Mental fatigue from repetitive tasks

Flow in Action:

Instead of framing all the walls of a remodel at once, complete one section fully—framing, plumbing, electrical rough-in—before moving on. You’ll catch coordination issues earlier and reduce punch list surprises.

Quick Fix: Identify one part of your process where you could test flow instead of batching. Try it on your next small project.

Pull vs. Push: Stop Forcing the Work

This concept gets to the heart of how your jobs get done. In a push system, work is handed off whether the next person is ready or not. In a pull system, the next step only starts when the person or team doing it is ready.

Push System Problems:

• Creates backlog and stress

• Causes rework from rushed or unclear handoffs

• Leads to finger-pointing and poor communication

Pull System Benefits:

• Teams work at a sustainable pace

• Clear signals for when to start and stop work

• Less overwhelm, more accountability

Real-World Example:

In a design/build firm, if the designer finalizes a plan and immediately sends it to production—even when permitting is still pending—that’s a push system. Instead, production should “pull” the project only when the design is final, permits are in hand, and materials are scheduled. This prevents idle time and keeps the build team focused on what’s truly ready.

Quick Fix: Map out your current workflow and ask: Where is work piling up? Who’s overwhelmed? That’s where you need to build in a pull system.

Why This Matters: Leadership, Culture, and Retention

When you eliminate waste, shift to flow, and empower your crew to pull work, the impact goes far beyond productivity.

• Leaders can lead. You spend less time firefighting and more time developing your team.

• Culture improves. People feel heard, valued, and supported when processes make sense.

• Retention increases. Skilled workers stay longer when they aren’t burned out or bogged down.

This isn’t about working harder. It’s about working smarter—and creating systems that support real humans doing real work.

Final Thoughts

Lean thinking isn’t about adding complexity—it’s about removing the friction that slows your crew down. When you learn to spot waste, prioritize flow, and build pull-based systems, you create space for your team to perform at their best.

These concepts are simple, but applying them consistently takes practice, structure, and support. That’s where a good coach comes in. Whether you’re just starting to explore Lean or ready to take it deeper, I’m here to help turn these ideas into action that fits your team and your business.
