Chapter 3 & 4 Software tools environment & Agile software development

What is CBSE?

Process of developing computer systems using reusable software components. Pre-existing software components into larger pieces

Object oriented software development tools

Class diagram, object diagram, object state diagram

Unified process tool

Unified Process

iterative modern process model (framework) from UML work and associated process. For large-scale software

Rational Unified Process (RUP)

Commercial version of unified process from IBM
Supplies all standard, tools, other necessities not in UP

Unified Modelling Language (UML)

A notation or language for development

Not a development method

Industry standard for modelling OO systems

Principal UML Models

Agile Methadology

Collection of principles that value adaptability and flexibility.

Adaptive SDLC

Mix of incremental and iterative. Adapt to the changing requirements based on new feedback

Predictive SDLC

Predict the complete workflow. Determine the cost, scope and timeline in early phases.

Pros of Adaptive SDLC

Flexibility & quick adjustments, agile methodology boost team collaboration, reduces bugs, high quality + technical exellence

Cons of Adaptive SDLC

Demands client/user involvement, continuous teamwork, lack of commitment could impact software quality, less detailed documentation.

Pros of Predictive SDLC

Easy to follow phases, laid down budget and timeframe, able to assume expected budget, specific timelines easier to monitor entire project

Cons of Predictive SDLC

Delayed development, additional costs of delayed, not ideal for complex projects, not suitable for flexible requirements.

SCRUM

KANBAN

EXTREME PROGRAMMING (XP)

an Agile project management methodology that targets speed and simplicity with short development cycles and less documentation.

The process structure is determined by five guiding values, five rules, and 12 XP practices

Crystal

lightweight or agile methodology that focuses on individuals and their interactions. The methods are color-coded to significant risk to human life. It is mainly for short-term projects by a team of developers working out of a single workspace.

Dynamic Systems Development Method

Features Driven Development

focuses on developing working software with features that satisfy client needs

Sprint Backlog

The user stories, goals and tasked linked to current sprint
