Study Notes

Course Objectives and Content

Analyze business needs to develop strategies for information services.
Utilize information gathering techniques to elicit user requirements and expectations.
Construct and interpret various analysis and design models, including UML diagrams.
Produce necessary documentation, including project plans during the analysis and design of information systems.
Design effective user interfaces and assess system usability.
Differentiate and evaluate various strategies for testing, installation, configuration, and maintenance.

Systems Development Life Cycle (SDLC)

A structured methodology for developing and maintaining information systems.
Involves orderly activities for each project phase with specific outcomes and deliverables.
Key phases include Planning, Analysis, Design, Implementation, and Maintenance.
Outputs consist of software and accompanying development documentation.

SDLC Planning Phase

Justifies the need for building an information system.
Establishes a project plan detailing how the project will be executed.
Project Initiation involves business needs, feasibility analysis (technical, economic, organizational), and the creation of a project plan.

SDLC Analysis Phase

Identifies who will use the system and outlines its intended functionality.
Consists of requirements determination and structuring to understand current practices and eliminate redundancy.

SDLC Design Phase

Converts solutions into system specifications detailing operational aspects.
Addresses hardware, software, network infrastructure, user interface, and database specifications.

SDLC Implementation Phase

Involves coding, validating, installing, and supporting the information system post-development.

SDLC Maintenance Phase

Focuses on systematically repairing and improving the system.
Maintenance is ongoing and incorporates repetition of earlier lifecycle phases.

Business Analysis

Encompasses practices that enable organizational change by defining needs and recommending value-delivering solutions.
Conducted within project boundaries or as part of continuous improvement.

Core Concepts of Business Analysis

Context: Influencing factors surrounding change which include organizational culture, demographics, technology, etc.

Computer-Aided Software Engineering (CASE)

Tools that support various SDLC phases, making processes more efficient across project initiation, planning, analysis, design, implementation, and maintenance.
Include diagramming tools for graphical representation, analysis tools to ensure specifications accuracy, and documentation generators for standard formats.
Code generators facilitate automatic creation of program and database code from design documents.

Outsourcing

The strategy of transferring some or all responsibilities for information systems applications and operations to external firms.
