How to use the Quadrants:

These quadrants help to understand the purpose and scope of different tests. You can use the quadrants by following these three steps: 

  1. Determine if the work being produced is more business-facing or technology-facing
  2. Determine if the testing is meant to guide development or critique the product based on the stage you are at in your development cycle or sprint
  3. The quadrant you land in provides guidance toward what type(s) of testing you should perform that sprint

Agile Testing Quadrants best practices

Here are some best practices to follow when using the Agile Testing Quadrants to help guide your testing strategy: 

  • Understanding goals: Identify testing needs based on project goals and map them to appropriate quadrants.
  • Test planning: Align testing efforts, prioritize tests, and plan strategies for each quadrant.
  • Test creation & execution: Develop and execute tests according to the quadrant-specific goals.
  • Continuous improvement: Adapt testing strategies based on feedback from each quadrant.
  • Collaboration & communication: Encourage team collaboration and transparent reporting based on quadrant-specific tests.
  • Flexibility & adaptability: Remain flexible to adjust testing strategies based on changing project needs.
  • Continuous learning: Foster a culture of knowledge sharing and skill development across all quadrants.


These examples illustrate how each quadrant of Agile Testing is applied in different scenarios, demonstrating their practical usage in software testing processes:

Shift left paradigm: Performing validation and testing early

In software development, evaluating test design and requirements is crucial. Recognizing the importance of early validation in shift left testing emphasizes its impact on optimizing software and fostering smoother development practices.

Design and requirements refinement

Before coding begins, refining design and requirements is key. This step establishes a clear path, reducing confusion and deviations in development.

Stakeholder collaboration

Early collaboration among stakeholders prevents future misalignments. Involving developers, testers, and business analysts sets a shared vision.

Mitigating risks through early review

Early detection and fixing of design flaws significantly reduce the likelihood of errors later in the development cycle. Identifying inconsistencies or conflicting requirements at an early stage minimizes risks, mitigating the need for extensive rework and optimizing resource utilization.

Establishing quality assurance frameworks

The early validation process lays the groundwork for test planning. Crafting comprehensive test cases and scenarios becomes feasible, ensuring that quality assurance measures encompass diverse testing scenarios, including functional, non-functional, and edge cases, enhancing overall product quality.

Streamlined development

Embracing early validation practices streamlines the entire development lifecycle. By eliminating ambiguities early on, teams can proceed with a more efficient testing approach. This results in optimized test deliverables that align closely with user expectations, business, and test objectives.

Shift left early testing example scenario

Here’s a table outlining the steps of early validation in shift left testing for a hypothetical task management application:

Early validation procedures—such as the review of design and requirements—within the framework of shift left testing are instrumental in optimizing software development practices and ensuring the delivery of high-quality software products.

Shift right paradigm: Analyzing production defects & usage patterns

In the dynamic landscape of software development, understanding how users interact with live systems is as crucial as pre-release testing. Exploring production defects and user behavior in Shift Right Testing is crucial for bettering software quality after deployment.

Analyzing production defects and user behavior post-deployment involves:

Defect analysis

Reviewing logs, error reports, and user feedback to identify and categorize issues encountered by users in the live environment.

Example: An e-commerce platform notices a sudden increase in abandoned carts. By examining error logs and user sessions, they identify a bug causing payment failures for a specific browser version.

Action: The development team reviews the error logs, identifies the browser-specific issue, and swiftly releases a fix.

Usage patterns

Studying user interactions, navigation paths, feature usage, and performance metrics to understand how users engage with the software.

Example: A social media app observes a drop in user engagement after an update. Usage analytics reveal users spending less time on the app after a particular feature was introduced.

Action: By studying user behavior data, the product team realized the new feature’s complexity was deterring users. They simplify the feature, leading to increased engagement.

Feedback collection

Gathering feedback through surveys, user interviews, or dedicated feedback channels to capture user sentiments and preferences.

Example: A software company launches a project management tool. They create a user feedback form within the app to gather user opinions and suggestions.

Action: Analyzing the feedback, they notice consistent requests for a specific integration. This data prompts them to prioritize and implement the integration, enhancing user satisfaction.

Data-driven insights

Leveraging analytics tools and user behavior tracking to derive meaningful insights for software improvement.

Example: A mobile gaming company releases a new version of their game. Tracking user interactions, they notice a significant drop in retention after a specific level.

Action: Analyzing the data, they realize that the level was overly challenging. They adjust the level of difficulty, leading to improved player retention.
