Course Overview

The Systems Development Essentials using Agile course is aimed at both existing and prospective systems developers as well as Business Analysts wishing to gain an overview of the issues and concepts involved in developing quality solutions that satisfy business requirements, using Agile approaches. The course studies a number of systems development life cycles, both defined and evolutionary, and examines the context in which different lifecycles could be applied before focusing in detail on an Agile approach.

Introduction

• Characteristics of software quality
• The purposes, objectives and tasks of systems development
• Roles and responsibilities in systems development
• Technical and interpersonal skills of the business analysts and solution developers

Systems architecture

• Enterprise, systems and infrastructure levels of architecture
• Inputs at an enterprise level
• Inputs at system and infrastructure level
• Model Driven Architecture

Development approaches

• Bespoke development
• Commercial off the shelf (COTS) software package solutions
• Configuring and customising COTS software package solutions
• Component-based systems development
• Service-based solutions and other approaches
• Evolutionary prototyping

Systems development lifecycles
