What Are The Different Types Of Software Development Life Cycle

What is the role of QA in SDLC?

Quality Assurance refers to the planned and systematic way of monitoring the quality of the process which is followed to maintain the quality of the product.

QA is proactive and plays important roles in each phase of SDLC.

Quality Control finds the defects in the product.

They rely on the test cases prepared by QA..

What is SDLC and STLC?

Software Development Life Cycle (SDLC) is a sequence of different activities performed during the software development process. Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process.

What is bug life cycle?

Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.

What is waterfall and agile?

The two main development methodologies are agile and waterfall. They are commonly applied to software development, and thus, project management as well. The main difference between agile and waterfall is that waterfall projects are completed sequentially whereas agile projects are completed iteratively in a cycle.

What are life cycle models?

The life cycle model is one of the key concepts of systems engineering (SE). A life cycle for a system generally consists of a series of stages regulated by a set of management decisions which confirm that the system is mature enough to leave one stage and enter another.

What is a software development life cycle model?

Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality softwares. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.
