CHAPTER EIGHTEEN​ ​- ​ METHODOLOGIES FOR SUPPORTING AGILE ORGANIZATIONS​

A set of vocabulary flashcards covering key concepts related to software development methodologies and service-oriented architecture from the lecture notes.

What are different examples of software developement methodologies?

• Waterfall​

• Agile​

• Rapid application development (RAD)​

• Extreme programming​

• Rational unified process (RUP)​

• Scrum​

Waterfall Methodology

A sequence of phases in which the output of each phase becomes the input for the next.

Iterative Development

Consists of a series of tiny projects

Agile Methodology

Aims for customer satisfaction through early and continuous delivery of useful software components developed by an iterative process
using the bare minimum requirements​

Rapid Application Development (RAD)

Emphasizes extensive user involvement in the rapid and evolutionary construction of working prototypes to accelerate the systems development process.

Prototype

A smaller-scale representation or working model of the users’ requirements or a proposed design for an information system.

The prototype is an essential part of the analysis phasewhen using a RAD methodology

Extreme Programming (XP)

Breaks a project into tiny phases, where developers cannot continue to the next phase until the first phase is complete.

Rational Unified Process (RUP)

Provides a framework for breaking down software development into four gates:

• Gate 1: Inception

• Gate 2: Elaboration

• Gate 3: Construction

• Gate 4: Transition.

Scrum

Uses small teams to produce small pieces of deliverable software using sprints, or 30-day intervals, to achieve an appointed goal.

• Under this methodology, each day ends or begins with a stand-up meeting to monitor and control the development effort​

• Sprint = interation

• Agile individuals like this method: may cost less than waterfall (could finish early, may only take a couple times, may not need to deliver a perfect product)

Service-Oriented Architecture (SOA)

A business-driven enterprise architecture that supports integrating a business as linked, repeatable activities, tasks, or services.
