Answer in about 500 words:

The Tesla battery innovation explained in the article may be a meaningful step forward in helping Tesla be successful over the longer term. Or, perhaps it is a minor change that is receiving more media coverage than is probably warranted, considering the nature of the change.

• To help decide whether this technological change is important, minor, or in between, please do a value chain analysis for Tesla Motors (just the motor car side, leave out the Solar City acquisition, to simplify the analysis). Feel free to either use what you already know about Tesla Motors to do the analysis or to research and read further, as you prefer. Also, write a few sentences describing what resources and capabilities are likely to be the most important influences on the future prospects of Tesla Motors as a firm and provide reasons for your choices.
