The two main types of methodologies

1. Traditional plan-driven models

2. Agile development models

This is a series of processes used in developing a software these are defined phases that describes the life cycle of the software until its completion.

SDM- Software Development Methodologies

Teams use this methodology to minimize risk (such as bugs, cost overruns, and changing requirements) when adding new functionality.

Agile Development methodology

In this methodology teams develop the software in iterations that contain mini-increments of the new functionality.

Agile methodology

3 pros of agile methodology

Software is released in stages or iterations.

Early defect detection and alignment of expectations.

User benefits is frequent, incremental improvements are delivered sooner.

These are set of practices that support organizational culture. They center on organizational change that enhances collaboration between the departments responsible for different segments of the development life cycle, such as development, quality assurance, and operations.
