Software Development Life Cycle 2019 | Auquall

SDLC means the software development cycle, the process of developing an information system with appropriate analysis, design, implementation, and maintenance. SDLC is called the open system interconnection of network connections or equivalent to the second layer of the OSI model. This level of the protocol ensures the correct flow of data from one level to another. SDLC is important because it breaks the entire software development life cycle and thus makes it easier to evaluate every part of software development as well as make it easier for programmers to function at each stage.


The field of software engineering is relatively new, and the introduction of scientific methods for software development has been a recent phenomenon. As software usage spread in the late 19s and early 19s and developed from programming languages ​​to procedural and high-level languages ​​as programming languages, software development in industry and universities developed. Experts began to find ways to improve the quality and reliability of their products. The result was the introduction and modification of SDLC and other formal SDLC-based development methods.

Furthermore, the SDLC is not a technical document - it is a practical document. Therefore, it is not very difficult to read technically, and most readers should be able to understand the basic concepts of a gradual approach to software development. Their time and effort in understanding SDLC will be a fruitful investment for their business.

An important stage of SDLC

Planning and analysis is the most important phase in SDLC. Many companies spend only 10–15% in both these stages and eventually fail because they did not plan and analyze the product required for the invention. Spending more time on these two steps will reduce unsuccessful time and reduce costs by producing a needy product or service. This step should not be ignored to produce more work and desired results.
