Reading discussion Brooks Jr., F. P. (1987) No Silver Bullet Essence and Accidents of Software Engineering. Computer, 20, McCracken, D. D. & Jackson, M. A. (1982) Life cycle concept considered harmful Gladden, G. R. (1982) Stop the life-cycle, I want to get off.

Class Exercise: Group: Learning to learn in groups Divide into groups of five. Spend 20 minutes – critically evaluating one of the articles provided by your lecturer and preparing group review. In no more than two minutes present your paper to the rest of the class (no visual aids allowed). – Briefly convey key points – Add value - iIllustrate with example – Reflect and critically evauate Review by lecturer.

IN THE BEGINNING THERE WAS THE LIFE CYCLE Life cycle models in system development Code and Fix Stage-wise and Waterfall Models The Spiral Model

What is a life cycle?

Life cycles and dev. methods

The Essence of Programming Adapted from (Royce, 1970)

The grandiose model Adapted from (Royce, 1970)

Task Leakage and Linkage Adapted from (Royce, 1970)

Remedies to the SDLC Adapted from (Royce, 1970)

A Spiral Model of Software Development and Enhancement Adapted from (Boehm, 1988)

Overlaying Ideas of Risk, Phase, Cost

Lifecycle Archetypes Code and Fix Stage-wise and Waterfall Models The Spiral Model …and Agile or Iterative Methods

Life cycles in firms; Ireland 2010

Build the Thing Right!

The Project View Quality Cost Time Scope

The SDLC as interrelated activity Requirements and Analysis Evaluation and Sourcing Test and Delivery Maintenance and Use

The Systems Approach Adapted from: (Gregory & Richard, 1963)

A basic SDLC
