Development of Interactive Multimedia

An Intermediate Process

Software Development Process

• Instructional process
• ADDIE
• Media - Development phase
• Concern with
• instructional content
• software development

Development process

• Analysis and planning
• Design
• Implementation
• Testing
• Maintenance and support

Analysis and planning

• Set goals
• Specify final application requirements
• Develop a work plan to carry out
• What it must do and how it will be built
• Set the target and how it will be reached

Work plan

• Time, tasks, and resources
• Resources - personnel, equipment, materials, outside services
• What and when needed

Requirements specifications

• Features: look and feel
• Time factors: milestones, delivery dates
• Details of how the application will be built
• Reviewable by senior management

Functional design

• What the application will do
• What the application will look like
• Considering the constraints
• Lays out exactly what the application will be able to do feature by feature.
• Read, comment, revise, approve

Technical design

• Before work begins!!!!!
• Breakup into modules
• Plan flow of data between modules
• Development tools and libraries
• File formats
• A blueprint for implementing what is described in the functional design

Prototypes

• Polish ideas
• Agree on user interface
• Paper, authoring platform, programming
• Goal - see and test before coding begins
• Find design flaws
• No perfect prototype
• Gain knowledge to begin
• Diminishing returns

Implementation

• Application is built
• Iterative and additive
• Release versions, build on each other
• Phases
• Alpha - functional design
• Beta - fine-tune user interface, freeze
• Gamma - data preparation, final

Alpha

• Incremental building
• Functionality increased
• Full & complete interface in demonstrable form
• Small sample set of text, graphics, sounds, "place holders"

Beta

• Full design, alpha version, reviewed and user tested
• Final revisions identified, prioritized and approved
• Functional design frozen
• Stop feature creep
• Final - few serious flaws, relatively finished

Gamma

• Data preparation complete
• Final quality assurance begins feature by feature

Quality assurance testing

• Ensure quality and reliability
• Prior to release
• Concludes with final release
• Ready to copy
• Field testing
• Sent to site

Support and maintenance

• Assistance from the company
• Doesn’t work
• Planned before problems arise
• Maintenance - improve and fix
• Planned from the beginning
