UML Modelling for Business Analysts: with Illustrated Examples

UML modelling is one of the widely used techniques in the software development industry. Business analysts use this technique to develop the requirements to make it suitable for the technology team and customers alike. After spending several years in the IT industry, we have realized that requirements (or incomplete or incorrect understanding of the requirements) have been one of the primary reasons for the failure of the software projects. This has been proven time & again by the CHAOS report published by Standish Group. So the motivation to write this book is to provide a comprehensive, detailed and practical guide on requirements development to enable every business analyst conduct this phase efficiently. This book deals with requirements development and its sub-phases with examples and case studies. We have selected UML diagrams as the modelling technique to explain and guide you through the entire process. Requirements development phase comprises of multiple steps comprising of: -Requirements Elicitation -Requirements analysis and modelling -Requirements specification and validation. Chapter 1 and 2 lays the foundation for the entire book. Chapter 1 provides fundamentals of software development life cycle methodology. Chapter 2 provides the basics of requirements development process in the overall context of SDLC. As the focus is on UML modelling, chapter 3 to chapter 8 deals with UML modelling. Chapter 9 deals with the requirements specifications and validation. We have presented complete requirements specification document in two formats: System Requirements specification (SRS) document. Use case specification document. We have also discussed structured analysis and design (SAD) methodology in the Appendix. We have also used two case studies, in addition to examples, to explain the concepts practically.
