- As shown in Chapter 2, smartphones are becoming a dominant form of computing, with more smartphones being sold than personal computers. A greater discussion of PC and smartphone sales appears in Chapter 13, along with statistics regarding the decline in tablet sales. Businesses have adjusted to this trend by increasing their investment in the development of apps for mobile devices. The number of mobile apps in the Apple App Store has increased from zero in 2008 to over 2 million in 2017. 3 Building a mobile app will be covered in Chapter 10. Walmart realized in the 1980s that the key to their success was information systems. Specifically, they needed to manage their complex supply chain with its thousands of suppliers, thousands of retail outlets, and millions of customers.

Take a moment to study the diagram above…look for the double-headed arrow. Notice that data flows down the supply chain from suppliers to retail stores. But it also flows up the supply chain, back to the suppliers so they can be up to date regarding production and shipping.
