--SOFTWARE DEVELOPMENT LIFECYCLE (SDLC)--

SDLC

1. Software Development Lifecycle (SDLC)

2. Overview SDLC is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The goal of SDLC is to minimize project risks through forward planning so that software meets customer expectations during production and beyond. This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure.

3. Why is SDLC important? Software development can be challenging to manage due to changing requirements, technology upgrades, and cross-functional collaboration. Here are some benefits of SDLC: · Increased visibility of the development process for all stakeholders involved · Efficient estimation, planning, and scheduling · Improved risk management and cost estimation · Systematic software delivery and better customer satisfaction
