Lean dictionary

Lean begins with knowledge of the right working methods. This Lean dictionary explains important technical terms from the fields of Lean Manufacturing, material flow, ergonomics, and continuous improvement. The short, clear descriptions provide direct support for daily work in the workplace.

Autonomous vehicles that move materials safely and efficiently – ideal for automating recurring transport.

In a nutshell:

Automated guided vehicles (AGVs) encompass all automated vehicles that handle internal transport. Two main types are distinguished:

  • AGV (Automated Guided Vehicle) / FTF (Driverless Transport Vehicle)
    → Guided driving on defined routes (magnetic strips, QR codes, lane guidance, laser trilateration).
  • AMR (Autonomous Mobile Robot) / FTS (Driverless Transport System)
    → Navigate freely, recognize environments independently and dynamically adjust their route.

Both variants react to sensors and safety zones and can be integrated into modern guidance and control systems.

Everyday analogy:

Imagine you are walking through the supermarket with a shopping cart:

  • An AGV would be like a car that rigidly follows a predetermined line on the floor. It stops if something is in its way – but strictly adheres to its route.
  • An AMR would be like a smart shopping cart that recognizes you, follows you and independently avoids obstacles – all without a predetermined path.

AGVs and AMRs also differ in their production processes. CREFORM brings this logic to everyday factory operations: with modular AGV systems and AMR-ready solutions that adapt to a wide variety of environments and can be seamlessly combined with conveyor technology, Karakuri mechanics, and the pipe connector system.

Lean context:

Automation of material flow, reduction of manual transport, increased safety & process stability, basis for digital, networked intralogistics (Industry 4.0), enables pull principle, synchronized supply & stable material flows.

  • AGVs are particularly suitable for standardized, repetitive processes.
  • AMRs are ideal when flexibility and adaptability are required.
With CREFORM:
  • Modular AGV systems – ideal for fixed routes, clear material flows, and line supply
  • AGV integration & AMR compatibility – flexibly combinable with conveyor technology, kitting trolleys, Karakuri mechanics or complete production cells
  • VDA 5050 perspective – future-proof operation via common interfaces
  • Scalable solutions – from simple material shuttles to complete intralogistics concepts
  • Seamless connection with roller tracks, kitting, one-piece flow and heijunka logics

We use our pipe connector system to perfectly adapt vehicles, transfer stations, docking points and routes – even for one-off production.

A visual warning signal that makes malfunctions immediately visible and enables a quick response.

In a nutshell:
A visual signaling and notification system that makes malfunctions immediately visible in order to react quickly.
Everyday analogy:
Just as a warning light in a car immediately signals that something is wrong, Andon makes problems in production visible. CREFORM creates this transparency through visual boards, integrated sensors, and systems that clearly display malfunctions – enabling teams to react immediately.
Lean context:
Enables transparency, stopping the production line in case of quality deviations, and rapid escalation.
With CREFORM:
We make deviations on the shop floor immediately visible through visual boards, sensors, and clear signals. This enables rapid responses, stable processes, and transparent production.

A production line in which one person efficiently operates several automatic machines.

In a nutshell:
“Load Load”: A line in which one person operates several automatic machines – the goal is flow production with minimal effort.
Everyday analogy:
It's like cooking when you have several pots in view and each one continues to simmer automatically: you move efficiently from station to station. In manufacturing, this means Chaku Chaku. CREFORM enables such line layouts thanks to ergonomic workstations, roller conveyors, and intelligent material supply systems.
Lean context:
Short distances, less waiting time, clear standard work, flexible operation of multiple stations.
With CREFORM:
We build ergonomic workstations, material handling systems, and roller track systems that enable multiple machines to run efficiently. In this way, we support true Chaku Chaku production lines.

Inventories are used in such a way that older goods are consumed first – for clear and stable storage processes.

In a nutshell:
Inventory principle: Use older goods/materials first to avoid obsolescence.
Everyday analogy:
Just like in a warehouse shelf where new products move to the back and older ones are used first, FIFO in production prevents obsolescence and chaos. With CREFORM flow racks and FIFO shelving, this principle works reliably and transparently.
Lean context:
Ensures quality, reduces inventory and lead times in warehousing and production.
With CREFORM:
We automatically implement FIFO using high-quality flow racks and roller rails. This ensures clear material sequences, low inventory levels, and maximum transparency.

Go where value is created – real problems are always recognized on site, not in the office.

In a nutshell:
"The real place" of value creation: observe on site, ask questions, act respectfully.
Everyday analogy:
It's like putting children to bed: you only truly understand the situation when you're actually in the room – not from the office. That's precisely what Gemba is. CREFORM accompanies companies to Gemba workshops directly at the point of value creation and identifies opportunities for optimizing material flow.
Lean context:
Fact-based decisions, daily walks, on-site leadership.
With CREFORM:
We analyze material flows directly on-site and implement improvements immediately within the process. We support teams with flexible structures and solutions that are aligned with actual needs.

Evenly smoothed production to avoid fluctuations and overload.

In a nutshell:
Smoothing of quantity and mix, even distribution of orders to reduce Mura, Muri, Muda.
Everyday analogy:
Doing laundry regularly, instead of doing everything on Sunday, saves you stress. Heijunka also smooths out production loads. With CREFORM material flow solutions like roller tracks, kitting systems, or Heijunka boxes, this consistency becomes practically achievable in daily operations.

Visual control of tasks and materials to keep processes flowing smoothly.

In a nutshell:
Visual control of work and inventory according to the pull principle.
Everyday analogy:
In the kitchen, one pack of coffee filters is in use, and a second is kept as a reserve. When the first pack is used up, it signals the need to buy a new one. This way, supplies don't run out, and unnecessary stock doesn't accumulate. This is precisely the principle behind Kanban in industry.
