Business Drivers Let’s look at: Compelling reasons to build applications for the web Changing the way we work on the web Business Drivers – Building New Applications To reach a broader audience Isolated applications Information from multiple sources needs to be available to multiple constituents Information must be available on multiple target devices Application management/maintenance is difficult Lack of real-time access to relevant information Reduce the number of technology platforms required To make it easier to do business with customers, vendors and partners in order to remain competitive “Me too” syndrome Business Drivers – Changing the way we work online Business were required to fit an application rather than the application fitting the business (SAP) Workflow is not managed or automated Business rules were not easily modifiable Reduce the number of technology platforms required Decrease time to market Locked into proprietary solutions.
