Siemens Building Technologies’ Lean Product Development Journey


Siemens Building Technologies is a part of the German multinational conglomerate Siemens AG. It is one of the world’s leading companies in building automation, fire safety, and building security, with its headquarters in Zug, Switzerland.

In order to retain its competitive position and to improve efficiency, the company launched the Lean Product Development initiative in 2010 and has come a long way since. The main expectation of the lean thinking implementation was to be more productive, enabling teams to reduce waste in all their daily activities and enable cross-functional collaboration with lean tools in all R&D projects.

This blog will provide insights into the different lean practices Siemens Building Technologies has implemented in the product development process using the Lean Innovation Model developed by the Lean Analytics Association (LAA) to discover and diffuse successful industrial cases and recently published in the Lean Product Development Best Practices Book.

Although lean in manufacturing was implemented much earlier as part of the Siemens Production System, in product development the lean journey started in 2010 when an official kick-off was carried out to increase awareness. Coaching support from external consultants started the same year focusing on training dedicated staff. As a first step, pilot projects were launched showing first benefits and reducing the skepticism for lean improvements. Pilot projects were carefully selected to ensure they were challenging but not too risky to ensure quick hits and implementations could be obtained successfully in one to two years.

In line with the first pilot projects, awareness training began at the headquarters in Zug for all employees. Training was spread globally and implementation of projects started in selected global sites. Projects have been continuously defined and launched.

Siemens Building Technologies’ Lean Product Development Journey



Through its journey, Siemens Building Technologies established best practices in several aspects of Lean Product Development. These practices were identified and structured according to the four building blocks of the Lean Innovation Model. Below are just some of the best practices identified and described in Siemens Building Technologies’ chapter of the Lean Product Development Best Practices Book recently published.


The company followed a bottom-up approach focusing first on the individuals to implement Lean Thinking in R&D projects to achieve strong engagement by all employees. To support the deployment of the lean PD strategy, three key roles were defined:

  1. Global Lean Coach – Engage employees to implement lean thinking in R&D globally. Coordinate the program. Provide and maintain methodology and toolbox. Roll out the training sessions and motivate local lean coaches and all employees to use the tools.
  2. Local Lean Coach – Enable lean thinking implementation at their own site. Listen to the local challenges and support local teams to define, document and communicate their lean projects in R&D.
  3. Teams – Groups of employees focusing on specific Lean Product Development practices, methods, and tools.


Aligned to the goal of implementing lean at all levels, Siemens Building Technologies developed a model to roll out specific training to develop competencies for all the employees, lean coaches, and management:

  1. All employees are trained on Lean Awareness training lasting 2.5 hours introducing lean thinking and encouraging them to use principles for their own R&D activities.
  2. Selected leading employees are invited to become lean coaches and attend a three-day training session; specifically in-depth explanations of the tools
  3. Employees in managerial positions are invited to attend a one-day session to understand the lean principles and their impact on their business.


Value Stream Mapping sessions are held to identify the current state or plan future state; a classification of waste has also been provided to all employees as a guidance to potential improvements in time, cost, and quality.

Kanban Boards are used regularly to create transparency on work status. Thereby work-in-progress is limited to assure flow in the process. Daily Stand-ups are used also to track performance and identify problems on a daily basis.

One of the key efforts was to identify tools that can support all levels on their daily activities. The vision was not to deploy too many tools but to concentrate on few that could be easily applied to solve product development challenges quickly and in a collaborative way.


Siemens Building Technologies continuously communicates internally why Lean Thinking is an important practice to maintain company’s competitiveness. Posters are designed and placed in different locations highlighting the key concepts and definitions. Another important practice developed in Siemens is to enable knowledge sharing by creating a very simple template to document the lean projects’ before and after results.
