Master's Thesis from the year 2011 in the subject Computer Science - Commercial Information Technology, grade: 1,0, University of Applied Sciences Stuttgart, language: English, abstract: This thesis examines the nature of fundamental business changes, how they affect a company, and how a management team can implement the change successfully. A fundamental business change is defined as affecting not only small technical or organizational niches of a department. It is rather the re-organization of a business as a result of the re-structuring of either the entire organization or a single department. It affects (often repeatedly) the majority of employees, the majority of processes and includes a large amount of technical changes. The introduction of Cloud Computing within an IT department is hereby used as an example. Cloud Computing is the obtaining of IT capabilities from an external provider, as a service in a pay-per-use manner and over the Internet. This new technology changes the business of an IT department fundamentally.
