Software Process Model

Software Process Model

• Waterfall Model: The basic development activity is regarded as a series of distinct independent stages, which is a kind of program-driven software process, which is helpful to standardize software development activities.

• Prototyping: A prototype is a partially developed product that strengthens the understanding of the system, helps clarify requirements, and selects viable design strategies.

• Iterative development: combine different activities, such as description, development, and validation, to build a series of versions during the development process and to progressively deliver parts of the system.

• Convertible Model: use automated means to transform requirements specifications into a system that can be delivered using a series of transformations.

The iterative nature of software development

Iterative development

• Release products more quickly
• Pursuit of product innovation
• High demand uncertainty
• Need to respond quickly to user changes
• Focus on user behavior

Incremental Model: Gradually add functionality to each new release until you construct the full functionality.
Iterative Model: Start by submitting a complete system that complements each subsystem's functionality in subsequent releases.
