briefly explain different phases in SDLC providing outcome of each phase

Development Life Cycle (SDLC)

SYSTEMS PLANNING:

Outcome: Preliminary Investigation Report

• Evaluation of the systems request
• Preliminary investigation to assess feasibility and alignment with organizational goals
• Documentation of findings in a preliminary investigation report

SYSTEMS ANALYSIS:

Outcome: System Requirements Document

• Requirements modeling to build a logical model of the new system
• Fact-finding techniques to gather information about the current system and user needs
• Development of business models, data and process models, and object models
• Documentation of system requirements in a system requirements document

SYSTEMS DESIGN:

Outcome: System Design Specification

• Creation of a physical model of the system
• Designing the user interface and identifying necessary inputs, outputs, and processes
• Determining the application architecture for developers to transform the logical design into code
• Preparation of a system design specification document

SYSTEMS IMPLEMENTATION:

Outcome: Fully Functioning and Documented Information System

• Construction of the new system through programming, testing, and documentation
• Installation of the system, including any necessary configurations or modifications
• If the system was purchased, configuring the software to meet the organization's requirements
• Delivery of a complete, functioning, and documented information system

SYSTEMS SUPPORT AND SECURITY:

Outcome: Ongoing maintenance, enhancement, and security of the system

• Maintenance activities to correct errors and adapt to changes in the environment
• Enhancements to provide new features and benefits
• Implementation of security controls to safeguard the system from external and internal threats
• Maximizing return on the IT investment through ongoing support, maintenance, and security measures

It's important to note that the SDLC phases can vary in their specific activities and deliverables based on the methodology or approach used in a particular organization or project.
