Introduction to the Book
I picked up this book mostly because I really needed a clear vision of customer requirements to push my project going forward. After finishing this book, I am so glad that I chose the right book.
Most development projects are going on a non-existing product. I believe most project managers or developers will agree that’s the nightmare if the requirement is incomplete, or unclear, or the client described A in a thousand of lines, what your understanding was B. How to prevent the misunderstood happened again and again?
In this book, Seilevel’s principals, Anthony Chen and Joy Beatty, literally wrote the book about Visual requirements models, introducing an effective way to identify software requirements. It also can apply to other business development. Visualization is a pretty neat way to keep most stakeholders interested and engaged. And very important, reduce misunderstands, so we can make the idea into reality, and deliver the work that is exactly needed.
After reading this book, I learned a new language, Requirements Modeling Language (RML), a language designed specifically to visually model requirements for easy consumption by executive, business and technical stakeholders.
A requirement is something that the business needs to have implemented in their solution. In most software development projects, it may involve designers, developers, testers, and implementation managers, and after the software delivered, it may also involve service people. Using RML on the project helps the whole team improve the way they elicit, model, and understand what their solutions can and cannot deliver.
Overview of Book’s Structure
The book is organized very well, so you can use it as a RML reference book. RML models are organized into categories of objectives models, people models, systems models, and data models (OPSD), so the whole book focuses on:
- Objectives Models describe the business value of systems and help you prioritize features or functions based on their values.
- People Models describe who is using the system, along with their business processes and goals.
- Systems Models describe what systems exist, what the user interface looks like, how the systems interact, and how they behave.
- Data Models describe the relationships between business data objects from an end-user perspective, the life cycle of the data, and how that data is used in reports to make decisions.
All four categories are needed in the requirement analysis. Development of models in each of the RML categories ensures that we have a bounded understanding of the solution can maximize the chances that the team will build the right solution.
