The Constructive Cost Model (COCOMO) is an algorithmic, parametric, software project cost estimation model. It uses regression analysis in which the independent variables (parameters) are derived from (1) historical software project data, and (2) current software project characteristics.

A testing technique primarily used to reduce the additional time dedicated to features that are already in existence. It also assists in DevOps practices like CI/CD such that the product is always ready to be deployed at any instant of time.

Application Programming Interface design is process of designing and developing APIs that exposes system's functionality and data to external entities.

Software release management oversees all the stages involved in a software release from development and testing to deployment. Good knowledge of build delivery, continuous integration and management skills. understanding of technical documentation. It guides the technology efforts from code development through testing and into production, focusing on coordinating pieces from various product deliverables that must come together to work as an integrated solution. Software release management is required anytime a new product or even changes to an existing product are requested.

Software Requirement Elicitation is an important process in SDLC where the requirements are gathered followed by analysis phase.
