People both inside and outside IT often ask what is software development. It is a process to create computer software using one or more specific programming languages that provides functionality to address particular business or personal objectives. The development of software is usually a planned initiative with a number of steps and stages that result in the creation of operational software. Hence a good definition is: “a process with a set of activities that create computer software products, including their design, development, testing, and deployment.” Software itself is a set of instructions or programs that tell a computer what to do. It is independent of hardware and makes computers programmable.
Since the advent of software product development in the 1960s, many different approaches have been used for developing the software; the most common today uses an agile approach to development. An agile software development definition includes an approach where development requirements and solutions are delivered through the collaborative effort of self-organizing and cross-functional teams and their customers. Unlike the more traditional and often inflexible development software examples, agile encourages and promotes flexible responses to change, by advocating adaptive planning, evolutionary development, early delivery, and continual improvement.
Software is developed using computer programming, carried out by a software developer. A software developer definition is “a person that creates software, either by themselves or in conjunction with others.” What do software developers do day-to-day? They use processes and techniques to create working software, including requirements definition, data flow design, code design, process flow design, flowcharting, code creation, software development testing, and debugging. The end-to-end process is sometimes referred to as the software development life cycle (SDLC). The term ‘full stack software developer’ is someone that develops both user-facing software and server software, including database development and the development of application interfaces.
