Cross-functional collaboration using Obeya at Siemens BT


Cross-functional collaboration using Obeya at Siemens BT

As part of Siemens Building Technologies lean product development journey, the company identified the need for a stronger cross-functional collaboration among the project teams as well as within them. This need led to the creation of two initiatives in which two types of Obeya were implemented: One for the multiple projects and one for individual project level.

About the Company

Siemens Building Technologies is 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.

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.

Obeya is a Japanese word for “War Room” or “Large Room” and can be referred as a dedicated physical space where core members of the cross-functional team meet regularly to discuss the project advancements, drawbacks and plan the upcoming tasks. Since Obeya brings the entire core team together in one place, it is often used for quick problem-solving and brainstorming sessions. Siemens Building Technologies identified that Obeya is beneficial to:

  1. Support quicker decision making
  2. Escalate issues to be solved as soon as possible
  3. Eliminate waste of excessive meetings and emails.

The company uses two types of Obeya; the Multi-project Obeya and the Project Obeya. Multi-project Obeya is a room where stand up meetings take place for 30 minutes on a weekly basis.  Here, project portfolio leaders, product managers, and line managers review projects in order to speed up decisions, reach resolutions and update project sheets and metrics. Multi-project Obeya meetings are led by the Head of R&D. On the other hand, Project Obeya facilitates two weekly stand-up meetings, lasting for 20 minutes and focusing on critical work packages, coordination of projects and review of project deadlines.


To ensure the effectiveness of the Obeya as a means of problem-solving, status reviews, and conflict resolution during projects, Siemens Building Technologies created a simple template to document the impact of the Obeya on lean projects by comparing the situation before and after the two types of Obeya concepts were introduced.

From the figure above, which shows the impact of Obeya in a project, it is worth noting that engagement and collaboration of project functional teams at all levels is important as it allows for a channelled effort towards fast and successful projects.

What benefits have you observed after the Obeya concept was introduced in your organizations? What challenges did you face and how did your teams react? Let us know on Social Media or on info@lean-analytics.org
