First of three engineers hired to start up a new company division in the United States. Previously, all engineering, marketing, and support was provided overseas at the company’s home office. An existing two subscriber line product was having problems with lightning surge damage and needed a cost reduction to stay competitive in the market.
- First “test” assignment was a cost reduction of the existing two subscriber line product. The product had already been through two previous cost reductions by the home office overseas. Reduced the cost of the product by 6%, which increased the corporate annual net profit by approximately $450,000 (1996).
- Redesigned and improved the lightning surge protection on the cost reduced model. One very large customer was having problems with lightning damaged units and was looking for a reason to drop ECI Telecom as a preferred provider. As a test and without prior notification, they required all approved vendor models to pass a 20,000 V, 1000 Amp lightning surge test. The new units survived without damage and ECI Telecom remained a preferred vendor, saving the company over $1,000,000 in annual sales.
