SAFe® Agile Software Engineering with ASE Certification

Foundations

Agile Software Engineering

The technical practices — test-first, continuous integration, quality design — that let teams build software with speed, quality, and adaptability at scale.

Why Technical Agility

Process agility fails without engineering practices that make software easy to change safely; ASE builds those practices.

Built-In Quality

Ensuring quality is created as software is built, through practices like test-first and continuous integration, rather than inspected in later.

Fast Feedback

Short feedback loops from tests and integration that catch problems early and cheaply.

Mindset

Agile-Quality Mindset

A commitment to keeping code clean, tested, and adaptable so teams sustain a fast pace.

Emergent Design

Letting design evolve through refactoring and learning rather than fixing it fully upfront.

Collective Ownership

The whole team owns and can improve all the code, supported by tests and shared standards.

Test-First

Test-First Development

Writing tests before code to specify behavior, drive design, and build quality in.

Test-Driven Development (TDD)

Developer test-first practice using red-green-refactor to create well-tested, well-designed units.

Behavior-Driven Development (BDD)

Business-facing test-first practice expressing behavior in Given-When-Then scenarios that become tests.

Acceptance Test-Driven Development

Defining acceptance tests collaboratively before development so teams share a clear, testable goal.

Test Automation

Automating tests so they run frequently, enabling continuous integration and fast feedback.

Continuous Integration

Continuous Integration (CI)

Frequently integrating and testing changes so defects surface early and the system stays working.

Version Control

Managing all changes in source control with practices that support frequent integration.

Continuous Delivery Pipeline

The automated flow that builds, tests, and delivers changes toward production reliably.

Trunk-Based Development

Integrating small changes frequently to a shared mainline to reduce merge risk.

Design & Quality

Refactoring

Improving code structure without changing behavior, kept safe by tests.

SOLID Principles

Object-oriented design guidelines that produce flexible, maintainable code.

Design Patterns

Proven, reusable solutions to recurring design problems.

Code Quality and Smells

Recognizing and removing signs of poor design like duplication and tight coupling.

Clean Code

Writing readable, simple, well-structured code that is easy to change and maintain.

Applying It

Executable Specifications

Tests that specify and verify behavior, doubling as living documentation.

Engineering in SAFe

Applying these practices across Agile Release Trains so quality and flow scale with the organization.

Continuous Improvement

Relentlessly improving engineering practices to sustain speed and quality over time.
