While the role of the business analyst in the IT industry has been established for 25 years, there has been a lack of standards and common practices throughout the industry. This is gradually changing with the creation of the International Institute of Business Analysis (IIBA). Determining Project Requirements is aligned with the standards set by IIBA and serves as a study guide for the IIBA certification program for business analysis professionals. This book provides complete coverage of the entire business analysis cycle, from enterprise analysis and planning to requirements gathering and documentation. It also includes case studies and techniques using data modeling and process modeling.
