The logo of Harting, a maker of industrial plugs and sockets, is pictured at the company's headquarters in Espelkamp, northern Germany, March 30, 2015. The Harting Group is working hard to developing an automated production line that takes orders online and makes plugs to a customer's individual specification. Harting is one of a growing number of German firms investing in software, fearing their excellence in mechanical precision and reliability -- the trademarks of "Made in Germany" valued by factory owners around the world -- will not be enough to guarantee them success for much longer.
