The Software Development Life Cycle (SDLC) is a structured process used by the software industry to design, develop, and test high-quality software. It provides a systematic framework to ensure that software projects are completed within time and cost estimates while meeting customer requirements.

The primary activities involved in the SDLC are:

• Requirement Analysis: Gathering and documenting user needs and system requirements to define what the software should accomplish.
• System Design: Translating requirements into a technical blueprint, including architecture, user interfaces, and data structures.
• Implementation (Coding): Converting the design specifications into actual executable code using chosen programming languages.
• Testing: Systematically identifying and fixing defects to ensure the software functions correctly and meets quality standards.
• Deployment and Maintenance: Releasing the software to the production environment and performing ongoing updates or bug fixes to ensure continued performance.

Feasibility studies are conducted to determine if a proposed software project is viable from various perspectives before committing significant resources. The primary types include:

• Technical Feasibility: Evaluates whether the current technology, hardware, and software expertise available are sufficient to build the system. It assesses if the technical requirements can be met within the project constraints.
• Economic Feasibility: Often referred to as cost-benefit analysis, this determines if the project is financially viable. It compares the estimated development and maintenance costs against the expected tangible and intangible benefits to ensure a positive return on investment.
• Operational Feasibility: Examines how well the proposed system solves the business problems and addresses the requirements. It considers whether the organization's culture, workflows, and personnel are capable of adopting and effectively using the new system.
• Legal Feasibility: Investigates potential legal conflicts, such as data privacy regulations (e.g., GDPR), intellectual property rights, licensing agreements, or contractual obligations that might hinder the project.
• Schedule Feasibility: Assesses whether the project can be completed within the required timeframe. It involves estimating the time required for each phase and determining if the deadline is realistic given the available resources.
