In the interest of showing what an Agile process might look like as a system is developed under it, the development of hms_sys will be broken down into several iterations. Each iteration, with a single, high-level goal, covers one or more chapters, and is concerned with a common set of Stories. Of the agile methodologies discussed in Chapter 4, Methodologies, Paradigms, and Practices, these chapters are closer to being a Kanban approach than anything else, since the number and total sizes of stories being completed in each iteration vary significantly between iterations. In a Scrum setting, these iterations would be time-constrained, broken out into time-limited chunks – that is, each iteration would be planned to last for some specific length of time. The following chapters and their corresponding iterations are...

Overview of this book
Software Engineering is about more than just writing code—it includes a host of soft skills that apply to almost any development effort, no matter what the language, development methodology, or scope of the project. Being a senior developer all but requires awareness of how those skills, along with their expected technical counterparts, mesh together through a project's life cycle. This book walks you through that discovery by going over the entire life cycle of a multi-tier system and its related software projects. You'll see what happens before any development takes place, and what impact the decisions and designs made at each step have on the development process. The development of the entire project, over the course of several iterations based on real-world Agile iterations, will be executed, sometimes starting from nothing, in one of the fastest growing languages in the world—Python. Application of practices in Python will be laid out, along with a number of Python-specific capabilities that are often overlooked. Finally, the book will implement a high-performance computing solution, from first principles through complete foundation.
