Systems Development Life Cycle

The term “system development life cycle,” or SDLC, is tossed around frequently when talking about the software develop process, but many people have only a vague idea about what the process actually entails and are hard-pressed to come up with a good answer when asked “What is system development life cycle?”

Here is a brief primer with a systems development life cycle definition and an answer to the question “What is system development life cycle and why is it important?”

What is system development life cycle?

The system development life cycle is a project management model that defines the stages involved in bringing a project from inception to completion. Software development teams, for example, deploy a variety of systems development life cycle models that include waterfall, spiral and agile processes.

What are system development life cycle stages?

Systems development life cycle phases include planning, system analysis, system design, development, implementation, integration and testing, and operations and maintenance.

What is system development life cycle iteration?

Iteration is what is system development life cycle’s greatest advantage, enabling faster development of systems by moving ahead with development without requiring full specifications upfront. Additional specifications can be introduced as the development process is repeated, producing new versions of the system at the end of each iteration.

What is system development life cycle security?

Security is critical when the intent of the system development life cycle is to produce software applications. Software is the most-attacked part of the security perimeter, and more than half of all successful security breaches begin with an attack on an application.

What is system development life cycle testing?

Testing is required during the system development life cycle to ensure that applications are free of flaws and vulnerabilities. Ideally, testing should happen at every stage of the SDLC, but because it adds unacceptable delay to development processes, it is often given short shrift or postponed until the later stages of the life cycle.

What is a system development life cycle testing provider?

A security testing provider offers tools that enable developers to perform tests on applications and development and production.

As one of the industry’s leading providers of application security testing solutions, Veracode offers a cloud-based subscription service that makes it easy for developers to embed security into all stages of the system development life cycle. With Veracode, developers can find and fix flaws at the most cost-efficient point in the development process and produce more secure software with every release.
