Software Development Life Cycle Waterfall Approach for Encore Documentation

SDLC Model  A framework that describes the activities performed at each stage of a software development project.  An Interactive DVD is considered a simple piece of software and therefore need to be documented using the SDLC Method.  We will be using waterfall approach for the documentation.

The Waterfall Model  The waterfall model is the classic lifecycle model, it is widely known, understood and commonly used.  In some respect, waterfall is the “common-sense” approach.  It was introduced by Royce in  It is more common among DVD Authors than any other SDLC Approaches.

Waterfall Model  Requirements – Defines needed information, function, behaviour, performance and interfaces.  Design – Data structures, software architecture, interface representations, algorithmic details.  Implementation – Source code, database, user documentation, testing.

Waterfall Strengths  Easy to understand, easy to use  Provides structure to inexperienced staff  Milestones are well understood  Sets requirements stability  Good for management control (plan, staff, track)  Works well when quality is more important than cost or schedule

Why to use Waterfall approach for DVD Authoring?  Requirements are very simple to begin with  Requirements are well known  Product definition is stable  Technology is understood  New version of an existing product  Porting an existing product to a new platform
