Study Notes

Software Development Lifecycle (SDLC) Phases

Phase 1: Planning: Defines project scope, objectives, and feasibility.
Phase 2: Analysis: Identifies user needs, gathers requirements, and develops system specifications.
Phase 3: Design: Creates a blueprint for the system, including data structures, user interfaces, and system architecture.
Phase 4: Development: Software coding, unit testing, integration testing, and system testing occur.
Phase 5: Implementation: Deploys the finished product, includes data conversion, user training, and ongoing system monitoring.
Phase 6: Maintenance: Regular updates, bug fixes, system improvements, and user support are provided.

RAD (Rapid Application Development) Methodology

Breaks down projects into smaller, manageable tasks.
Optimizes team efficiency through task-oriented structure.
Delivers working products quickly.
Encourages constant communication and feedback between team members and stakeholders.
Emphasizes iterative design and construction, allowing for faster development without sacrificing client satisfaction.

Iterative Development

Divides the overall project into a series of versions developed sequentially.
Prioritizes fundamental requirements for the initial version.
Provides an early version of the system to users for feedback.
Incorporates user feedback into subsequent versions.

Agile Development Approaches

Extreme Programming (XP)
Scrum
Dynamic Systems Development Method (DSDM)

Extreme Programming (XP) Methodology

Values: Simplicity, Streamlined Communication, Consistent Feedback, Respect, Courage.
Best used for projects with: Changing functionality, evolving requirements, tight deadlines, small teams, close customer collaboration, and automated testing.

Rational Unified Process (RUP)

Object-oriented system development methodology based on an iterative, incremental approach.
Four Phases:
- Inception
- Elaboration
- Construction
- Transition

Timeboxing

A technique where a fixed deadline is set for a project, and functionality is reduced if necessary to meet the deadline.
Focuses on delivering a working product within a timely manner.

Project Methodologies

Waterfall development
Agile Methodologies (eXtreme Programming, Scrum)
Rapid Application Development (RAD)
Joint Application Development (JAD)

Factors to Consider When Choosing a Methodology

Clarity of user requirements
Familiarity with technology
Project complexity
Reliability
Time frame
Schedule visibility

Project Management Tasks

Estimation
Work planning
Staffing
Team motivation
Conflict management
Project charter creation

Project Charter

A document that outlines the project's norms and ground rules.
