The incremental model is a software development process where the product is designed, implemented, and tested incrementally (a little more is added each time) until the product is finished. It involves breaking down the software into smaller, manageable modules or increments, each of which is developed and delivered separately.
Main Features:
- Phased Development: The project is divided into multiple increments, with each increment delivering a portion of the functionality.
- Early Delivery of Core Features: The first increment typically includes the most critical or basic features, allowing users to start using the system early.
- Iterative Refinement: Subsequent increments add more functionality, refine existing features, and improve performance based on feedback.
- Flexibility in Requirements: Changes can be incorporated in later increments without redesigning the entire system.
Key Principles:
- Modularity: The system is structured into independent modules, each developed and tested separately.
- Prioritization: Features are prioritized, with high-priority functionalities delivered first.
- Feedback-Driven: User feedback from early increments guides improvements in later ones.
Example:
A mobile banking app could be developed using the incremental model:
- Increment 1: Basic login and account balance viewing.
- Increment 2: Fund transfer and bill payment features.
- Increment 3: Investment portfolio management.
- Increment 4: Advanced security features like biometric authentication.
For scalable and efficient deployment of such increments, Tencent Cloud's Serverless Cloud Function (SCF) and Cloud Container Service (TKE) can help manage and scale each module independently, ensuring smooth and rapid delivery.
