In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
mychillo The following outline is provided as an overview of and topical guide to software development: . Software development – development of a software product, which entails computer programming (process of writing and maintaining the source code), and encompasses a planned and structured process from the conception of the desired software to its final manifestation.

[8] Royce's five additional steps (which included writing complete documentation at various stages of development) never took mainstream hold, but his diagram of what he considered a flawed process became the starting point when describing a "waterfall" approach. [11] [12]
A process step, usually called an activity, is denoted by a rectangular box. A decision is usually denoted by a diamond. A flowchart is described as "cross-functional" when the chart is divided into different vertical or horizontal parts, to describe the control of different organizational units.
A writing process is a set of mental and physical steps that someone takes to create any type of text. Almost always, these activities require inscription equipment, either digital or physical: chisels, pencils, brushes, chalk, dyes, keyboards, touchscreens, etc.; each of these tools has unique affordances that influence writers' workflows.

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.

The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
