Any application analysis project begins with assessing the organization's business needs and how these can be fulfilled using technology. The interviewer expects you to have a detailed process for your assessment. The information they want you to provide includes what aspects of the business processes you examine, questions you ask the business unit leaders, and your approach to matching technology solutions to the business requirements. They may also be interested in how you stack rank items such as costs, ease of implementation, training requirements, and other factors which impact how well the organization can adopt new technology.
