IT business skill No. 5: Understanding the company's business model
"Business model" is the buzzword version of "how the business works." It's how the actions the company performs lead to customers deciding to buy what the company has to sell at prices that return a profit.
IT pros who understand the business model are in a position to suggest ways IT can make their company more effective -- especially the IT they're working on right now. IT pros who don't are limited to talking in glittering generalities that might or might not have any relevance to making the company more successful.
