Systems Development Projects:
Software development life cycle (SDLC)
Systems Development Life Cycle - ANS-structured, step by step approach for developing an IS.
Called a waterfall methodology since it is step my step
System Acquisition life cycle - ANS-Structured step by step approach to purchasing an IS
SDLC:Planning - ANS-1. Define the system using CSF
2. set the scope of the project
3. Develop the project plan
SDLC: Analysis - ANS-End users and IT specialists:
1. Gather business requirements, includes joint application development sessions
2. Prioritize requirements
SDLC: Design - ANS-IT specialists design a technical blueprint include:
1. Technical Architecture
2. System models
SDLC: Development - ANS-Implementation of design plans:
1. Technical Architecture
2. Database and programs
SDLC: Testing - ANS-1. Creating a test plan
2. Doing the test
types of testing need to be done:
Unit testing - testing individual units of code
System testing - verifying that the units of code function correctly when put together in a system
Integration testing - verifying that separate systems work together
User acceptance testing (UAT) - determining if the system satisfies the business requirements
and enables users to perform their work correctly
SDLC: implementation - ANS-1. Write user documentation on how to use the systems
2. Training users
Ways to implement a system - ANS-Parallel Implementation
Plunge implementation
pilot implementation
phased implementation (install parts of a system systematically)
SDLC: Maintenance - ANS-Monitor and support the system
