The group Abacus presented on the system development life cycle (SDLC), which describes the process of planning, creating, testing, and deploying an information system. The SDLC includes phases for planning, analysis, design, implementation, and maintenance. In the planning phase, the problem and scope are defined. Analysis involves gathering and validating requirements. Design covers creating interfaces, databases, and other system components. Implementation is when coding integrates modules. Maintenance provides support once the system is installed.

2. System development life cycle:
Software engineering to describe a process for
planning, creating, testing, and deploying an
information system.

3. Phases in SDLC :
 Planning
 Analysis
 Design
 Implementation
 Maintenance

5. Planning
 Problem and scope
 Overview the new system and determine
 Confirm project feasibility and produce
 Phase, threats, constraints, integration
 A feasibility report for the entire project is created at
the end of this phase.

6. Analysis
 Gather, analyze, and validate the information.
 Requirements and prototypes
 Alternatives and prioritize the requirements.
 Information needs of end-user and enhances

7. Design
 Design of application, network, databases, user
interfaces, and system interfaces.
 Create a contingency,
 Training, maintenance, and operation plan.
 Review the proposed design.
 Finally, prepare a design document which will be used
during next phases.

8. Implementation
 Implement the design into source code through
coding.
 Combine all the modules together into training
environment that detects errors and defects.
 Integrate the information system into its environment
and install the new system.

9. Maintenance
 Phone support
 Physical on-site support for users that is required once
the system is installing
 Handling the residual errors and resolve
 Maintenance and support
 Needed for a longer time for large systems and for a
short time for smaller systems.
