SYSTEM DEVELOPMENT LIFE CYCLE (SDLC) Flashcards
WHAT IS THE SYSTEM DEVELOPMENT LIFE CYCLE?
A structured process used to develop and implement software applications & consists of multiple key phases that are critical for building a robust and effective system
WHAT ARE THE 7 PHASES OF SDLC?
- Planning
- Requirements Analysis
- Design
- Coding
- Testing
- Deployment
- Maintenance
WHAT IS THE PLANNING PHASE?
- first phase
- involves defining the software’s purpose and scope
- team collaborates to understand the end users’ needs and the goals the software should meet
- key documents such as the Project Plan & Software Requirement Specification (SRS) are created which detail the software’s functions, necessary resources, possible risks, and a project timeline
WHAT IS THE “REQUIREMENTS ANALYSIS” PHASE?
- the second phase
- seeks to identify and record the precise requirements of the final users
- conduct interviews, surveys, and focus groups to understand the users’ expectations and needs
- these efforts result in a Requirements Specification Document which outlines the software’s purpose, features, and functionalities, acting as a guide for the dev team and providing cost estimates if needed
WHAT IS THE “DESIGN” PHASE?
- the third phase
- outlines the software’s structure, navigation, UI’s, and database design ensuring that the software is user friendly and performs its tasks efficiently
- this step creates a Software Design Document (SDD) which becomes the roadmap for the coding phase
WHAT IS THE “CODING” PHASE?
- the 4th phase
- developers write code guided by the SDD and coding guidelines
- team members carefully examine each other’s work to identify bugs or inconsistencies
WHAT IS THE “TESTING” PHASE?
- the 5th phase
- involves a thorough examination of the software for any bugs or glitches
- the goal is to ensure flawless software before it reaches the end users
- testing involves unit testing, security testing, integration testing, system testing, and acceptance testing
- each bug/flaw is documented in detail and returned to the developers to fix
WHAT IS THE “DEPLOYMENT” PHASE?
- the 6th phase
- this is when it is presented to the users by pushing it to the production environment
- this may include user manuals, conducting training sessions, or offering on-site support
WHAT IS THE “MAINTENANCE” PHASE?
- the 7th phase
- constant assistance and improvement by responding to user feedback, resolving unexpected issues, and upgrading the software based on users’ evolving requirements
- involves software updates, patches, and fixing bugs
WHAT IS THE AGILE MODEL?
- a project management framework that breaks projects down into several dynamic phases, commonly known as sprints
- after each sprint, teams reflect and look back to see if there was anything that could be improved so they can adjust for the next sprint
- the sprints are: plan, design, develop, test, deploy, and review
