GPS · Generic Production System

A reference model for effective production systems.

The Lean4Y GPS provides orientation for companies that want to connect Lean, leadership, processes, performance indicators and capability building into an understandable overall system.

Why a reference model?

Many companies already have Lean methods, standards, shopfloor management, problem solving, performance indicators and improvement activities.

The challenge is often not the absence of individual tools, but the connection of these elements into a clear production and leadership logic.

GPS provides structured orientation. It helps classify existing approaches, make gaps visible and systematically develop a customer-specific production system.

GPS is not a ready-made company system. It is a reference model from which a suitable customer-specific production system is developed.

The five levels of GPS

The Generic Production System structures production systems into five connected levels.

These levels make visible how principles, methods, tools, management mechanisms and data must interact so that Lean is understood not as an isolated measure, but as a system.

GPS Lighthouse
Principles Value, value stream, flow, pull and perfection as fundamental orientation.
Methods Approaches such as Lean Management, Standard Work, Shopfloor Management or Just-in-Time.
Tools Practical instruments such as 5S, Kanban, problem solving, visual management or TPM.
KPIs and Management Performance indicators, routines and leadership mechanisms for aligning daily work.
Data and Transparency Reliable information as the basis for decisions, management and improvement.

What GPS provides

GPS helps view a production system not as a collection of methods, but as a connecting architecture for leadership, processes and improvement.

Create orientation

GPS structures principles, methods, tools, performance indicators and data into an understandable overall logic.

Make connections visible

It shows which elements already exist, how they interact and where gaps remain.

Prepare customer systems

It provides the basis for developing a clear and usable company-specific production system.

From GPS to a customer-specific production system

GPS is not simply transferred to a company. It serves as a structured starting point.

During the concept phase, the relevant principles, methods, tools and leadership routines are clarified for the specific company.

This creates a production system that fits the organization, processes, leadership structure and maturity level of the company.

Typical results

  • clear production-system architecture
  • shared understanding of Lean and leadership
  • structured classification of existing initiatives
  • visible gaps and priorities
  • roadmap for introduction and anchoring
  • basis for capability building through Academy and internal training

Who benefits most from GPS

Executive Management

When Lean, production, leadership and improvement need to be connected more strategically.

Operations Management

When plants, sites and functions require a shared production-system logic.

Lean and CI Leaders

When existing methods, projects and standards need to be brought into a clear architecture.

GPS and Lean4Y Academy

The Lean4Y Academy complements GPS where knowledge needs to be standardized, repeatable and scalable.

It supports the sustainable anchoring of a production system without replacing consulting work.

It helps leaders, Lean professionals and teams understand the logic behind methods, tools and leadership routines.

Capability building as an anchoring element

  • create shared terminology
  • teach fundamentals systematically
  • develop leaders and teams
  • make knowledge repeatedly available
  • support implementation through learning materials
