The incremental model is a software development process where requirements are divided into independent modules, each going through phases of requirements, design, implementation, and testing. This model allows for progressive enhancements and updates, making it suitable for various applications including mobile app development and educational curriculum design. Advantages include faster initial delivery and flexibility, while disadvantages involve higher costs and potential integration and scope challenges.

3. WHAT IS INCREMENTAL
MODEL ?
 Incremental model is a software process model where
requirements are broken down into multiple
standalone modules.
 Each Module (independent unit) passes through the
requirements, design, implementation and testing
phase.

4. WHAT IS INCREMENTAL
MODEL ?
 Each subsequent (coming after something in time)
release of module adds function to previous
module.
 The process continues till the end product is
achieved.

DEVELOPMENT
Many software companies use the incremental model to develop
their products.
When creating a mobile app, developers often use the incremental
model to release updates and new features over time.
Companies that manufacture physical products may use the
incremental model to develop new versions or iterations of their
products.
When designing educational curriculam, educators may use
the incremental model to develop and implement new teaching
materials and methods over time

MODEL
ADVANTAGES
Modularity
Work with small size team
Speed
Initial product delivery is faster
Flexibility
Can accommodate changes
Feedback
Customer’s response/feedback is considered

8. INCREMENTAL
MODEL
DISADVANTAG
ES
Cost
Total cost is higher than the expected cost
Integration Challenges
Integrating new increments can be complex, requiring careful
coordination to avoid compatibility issues with existing systems.
Potential for Scope Creep
Flexibility in accommodating changes may result in the project
scope expanding beyond initial expectations.
Preparation
Needs good planning and design
