Looking at the supplier portion of the competitive forces model, part of the reason General Motors was unable to produce cars inexpensively in comparison to their competitors was that they were producing a lot of their own parts. Their competitors were able to purchase parts from outside vendors at lower prices. General Motors viewed this as an opportunity and has since shed a lot of workers and factories and are currently searching everywhere for the lowest prices on parts. Also General Motors was very slow at producing cars because of old information systems and outdated processes. A lot of General Motor 's systems could not communicate with each other, which was causing a major lag in the production of automobiles. By integrating these systems they were able to become faster and leaner and were able to increase their customer focus [Laudon & Laudon, 2005].
In the competitive forces model, General Motors also has influence from new products and services to reduce costs and increase efficiency. General Motors wants to experiment with new ways to serve
