DreamWorks Animation Turns to Technology for Production Support

• Problem: Gaining an edge in an intensely competitive market, working with technology-intensive processes.

• Solutions: Deploy custom-built E-motion software to render more realistic animations and increase quality of films.

• HP processors, Linux, and high-speed network facilitate rapid production schedule, increasing productivity.

• Demonstrates IT’s role in strengthening a firm’s product and productivity beyond what human talent can accomplish.

• Illustrates digital technology’s role in gaining an advantage in a fiercely competitive market.



IT Infrastructure

• Defining IT infrastructure

• Evolution of IT infrastructure: 1950-2007

• Electronic accounting machine era: 1930-1950

• General-purpose mainframe and minicomputer era: 1959 to present

• Personal computer era: 1981 to present

• Client/server era: 1983 to present

• Enterprise Internet computing era: 1992 to present



IT Infrastructure

• Technology drivers of infrastructure evolution

• Moore’s Law and microprocessing power

• The Law of Mass Digital Storage

• Metcalfe’s Law and network economics

• Declining communications costs and the Internet

• Standards and network effects

applications



• Read the Interactive Session: Technology, and then discuss the following questions:

• What problems do Linux and other open-source software address? How does open-source software help solve these problems?

• What issues and challenges do open-source software present? What can be done to address these issues?

• What are the business as well as the technology issues that should be addressed when deciding whether to use open-source software?

Is It Time for Open-Source?





• Software outsourcing

• Changing sources of software

• Software packages and enterprise software

• Application service providers

• Software outsourcing



• Read the Interactive Session: Technology, and then discuss the following questions:

• Compare Thermos’s experience with an application software provider with the experience of ResortCom.

• Why do you think Thermos had an easier time with a hosted software service than ResortCom? What management, organization, and technology factors account for this difference?

• If your company was considering using an application service provider, what management, organization, and technology factors should be addressed when making your decision?
