HPC has successfully implemented HPC Engineering Change Management at S. Siedle & Söhne Telefon- und Telegrafenwerke OHG.

Our Client

S. Siedle & Söhne Telefon- und Telegrafenwerke OHG is one of the leading manufacturers of building communications technology in Germany and Europe. As a traditional family company it produces everything that is used for communication in and around the house - for more than 260 years at the same location, with uncompromising quality and award-winning design.
In 2015, Siedle achieved a consolidated turnover of 92 million euros with 550 employees. In Germany, Siedle's door intercom systems reach a market share of around 50 percent. The export share is almost 25 percent.
