Systems Development Life Cycle
What is SDLC?
A classical process used to develop information systems
What is the SDLC?
Systems Development, Requirements analysis, Component Design, Implementation and Systems Maintenance
What are the 5 phases of SDLC?
Define systems goals and scope, assess feasibility, form a project team
PHASE 1: What is System Deffinition?
Cost, schedual, technical and organisational (culture etc)
PHASE 1: In Systems Definition, what do they look at when assessing feasbility?
Both IT personnel and user representatives. PM and IT inhouse or outside
PHASE 1: In Systems Definition, who is envolved in the project team?
Manager, systems analysts, programmers, software testers and users
PHASE 1: In Systems Definition, what is an example of a typical development team?
Determine and document the specific features and fucntions of the new system
PHASE 2: What is Requirements Analysis?
Determing requirements, obtain users approval
PHASE 2: In Requirements Analysis, what are the 2 phases?
Designing the each of the 5 components
PHASE 3: What is Component Design?
To build, test and convert the users to the new system
PHASE 4: What is Implemenation?
Build components, test, intergrate components, intergrated test, convert
PHASE 4: What are the stages of Implemenation?
Pilot. phased, plunge and parallel
PHASE 4: What are the 4 conversion methods?
Implementing entire system in limited portion of the business
PHASE 4: What is pilot installation?
Installing in phases across the organisation
PHASE 4: What is phased installation?
Old system turned off, new system turned on
PHASE 4: What is plunge installation?
The new system runs parallel to old system until new system is tested and fully operational
PHASE 4: What is parallel installation?
Fix system to work correctly or adapt it to changes in requirements
PHASE 5: What is Systems Maintenance?
Record requests for change, prioritze requests, fix failures
PHASE 5: What are the 3 processes in Systems Maintenance?
Waterfall, Requirements documentation, schedual/budget, approval needed, user expectation
What are the problems with SDLC?
