This book aims to help readers move from novice programmer to software developer. It explores the methods and approaches employed in industry and talks about the difference between writing code and developing safe, efficient software that meets the needs of a customer.

considers the place of software in the context of a business, looking at off-the-shelf versus bespoke options, as well as at developing in-house versus using external suppliers, and the implications of these decisions on the cost and delivery of a product.

looks at the high-level components both of front-end and back-end systems. It discusses what these are and how they interact with one another, and looks at why user experience (UX) and user interface (UI) development are important.

examines the software development life cycle (SDLC) and the secure SDLC (SSDLC). It also looks at different development methodologies, such as Agile and waterfall, and how they impact on the SDLC.

discusses user requirements, the forms they can take and how to establish them. It covers communication with the customer, how to define a problem to be solved and how to establish this with a customer, whether a business, individual or a group.

covers software development approaches, looking at a variety of paradigms and their advantages and disadvantages. It discusses in detail procedural, object-oriented and functional programming, and outlines how to develop software using modular programming.
