Software development is the process of designing and implementing a software solution to satisfy a user. The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release .
The term was first used to describe a software development process introduced by James Martin in 1991. According to Whitten (2003), it is a merger of various structured techniques, especially data-driven information technology engineering, with prototyping techniques to accelerate software systems development.

Information technology (IT) is a set of related fields that encompass computer systems, software, programming languages, data and information processing, and storage. [1] IT forms part of information and communications technology (ICT). [ 2 ]
The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload. [5] A software engineer applies a software development process, [1] [6] which involves defining, implementing, testing, managing, and maintaining software systems; creating and modifying the development ...
Software companies aim to deliver a high-quality product on time and under budget. A challenge is that software development effort estimation is often inaccurate. [21] Software development begins by conceiving the project, evaluating its feasibility, analyzing the business requirements, and making a software design.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Set of software development practices DevOps is a methodology integrating and automating the work of software development (Dev) and information technology operations (Ops). It serves as a means for improving and shortening the systems development life cycle. DevOps is complementary to ...
Software development requires use of a cross compiler, which runs on a computer but produces executable code for the target device. Debugging requires use of an in-circuit emulator, and debugging hardware such as JTAG or SWD debuggers. Software developers often have access to the complete kernel (OS) source code.
