They’re meant to make an impression on visitors, employees and clients: the entrance lobbies of company buildings. They reflect how the companies see themselves and what image they want to reflect.This week, we look at the lobby of SAP.   The company's headquarters are in the town of Walldorf in southern Germany. The town's name has become synonymous with the software maker. Some 14,000 people live here, and 5,500 of them work at SAP. The company's rambling grounds lie like an enormous UFO at the edge of the tranquil town, which features many single-family houses. The construction of the SAP building and its dark brown color recall the style of past eras. A few weeks ago, a new reception building was opened, which is intended to give the company a fresh look. This new portal is used by software developers on their way to work as well as by clients and visitors to SAP. And they literally walk over "software installations." Report by Christoph Kober
