The Systems Development Life Cycle (SDLC) is a step by step process for developing information systems or software. It includes planning, analysis, design, coding, testing, deployment and maintenance to ensure quality, efficiency and user satisfaction.

Benefits of Systems Development Life Cycle (SDLC) – 

1. Provides a structured framework, ensuring timely completion, budget adherence and resource optimization through clear goals.
2. Ensures reliable, scalable and maintainable systems through rigorous testing, validation and continuous improvement methodologies.
3. Minimizes expenses by streamlining processes, eliminating rework and optimizing resources, resulting in cost effective system development solutions.
4. Ensures systems meet user requirements through iterative feedback, testing and validation, resulting in intuitive and effective solutions.
5. Streamlines processes, eliminates unnecessary steps and utilizes iterative methods for reducing development time and accelerating project delivery timelines.
6.  Identifies and mitigates potential risks through structured analysis, contingency planning and ongoing monitoring and assessment phases.

Challenges to SDLC include changing user requirements, inadequate resources, technical complexities, communication breakdowns, tight deadlines and limited budget. Additionally, managing stakeholder expectations, ensuring scalability and adapting to emerging technologies pose significant hurdles.
