1.1 SDLC

The System Development Life Cycle (SDLC) is a process used to design, develop, and maintain software or information systems. It involves several stages, including:

  1. System Study: Initial assessment of the existing system and identification of the need for a new system.
  2. Feasibility Analysis: Evaluation of the project's technical, operational, and economic feasibility.
  3. Requirement Analysis: Gathering and defining detailed requirements from stakeholders.

  1. System Design: Creating a blueprint for the system's architecture, components, and interfaces.
  2. Implementation: Actual coding and development of the system.
  3. Testing: Thoroughly testing the system for functionality, performance, and reliability.
  4. Deployment: Rolling out the system to the intended users.
  5. Maintenance: Ongoing support, updates, and enhancements to keep the system functional and relevant.

Each stage plays a crucial role in the overall development process, ensuring that the resulting system meets user needs and is of high quality.

1.2 Reasons For Maintenance and Updates

Software updates are important for several reasons, this is called post deployment phase:

  1. Security: Updates often include patches to fix security vulnerabilities that could be exploited by malicious actors.
  2. Bug Fixes: Updates address bugs and glitches that can affect the software's functionality and user experience.
  3. Performance Improvement: Updates can optimize code, enhance speed, and reduce memory usage, leading to better overall performance.
  4. Compatibility: Software updates can ensure that the software remains compatible with the latest operating systems, hardware, and other software.
  5. New Features: Updates may introduce new features, functionalities, or improvements that enhance user experience and provide additional capabilities.
  6. Regulatory Compliance: Updates might include changes to adhere to new industry regulations or legal requirements.
  7. User Feedback: Developers often incorporate user feedback into updates to address usability issues and enhance user satisfaction.
