According to the SAFe DevOps Practitioner 6.0 study guide and handbook, the Release activity is triggered by a business decision to go live. This means that the Solution is ready to be delivered to end users and customers, based on the validation and testing done in the previous activities. The handbook states that "The Release activity is triggered by a business decision to go live."1 Therefore, this activity involves releasing value to customers on demand, while also measuring and learning from the feedback.

According to the SAFe DevOps Practitioner 6.0 study guide1, hypothesis evaluation is important when analyzing data from monitoring systems in the Release on Demand aspect because it helps link objective production data to the hypothesis being tested. Hypothesis evaluation is the process of measuring and comparing the actual outcomes of a hypothesis with the expected outcomes based on customer feedback and business value. Hypothesis evaluation helps DevOps teams to validate or invalidate their hypotheses, learn from their mistakes, and improve their solutions. By linking objective production data to the hypothesis being tested, DevOps teams can see how well their solutions are delivering value to customers and achieving their goals.

gemba walks are an important competency in support of the Collaborate and Research activity of the DevOps Health Radar. Collaborate and Research is the process of creating alignment on what needs to be built, synthesizing Solution ideas into ART Backlog Features, and utilizing WSJF to prioritize a DevOps backlog. Gemba walks are a technique where the product team observes how stakeholders execute the specific activities in their operational value streams to identify opportunities for relentless improvement. Gemba walks help the product team understand the customer needs, market problems, and solution requirements from the perspective of those who deliver value to customers. Therefore, gemba walks are essential for collaborating and researching with stakeholders and validating or invalidating hypotheses.

Gated commits are a key technical practice that enables trunk-based development. Gated commits are a mechanism that ensures that only code that passes certain quality checks and tests can be committed to the main trunk of the shared codebase. Gated commits prevent broken changes from affecting other developers or the Continuous Delivery Pipeline. Gated commits typically involve the following steps:

• A developer writes code and runs local tests on their own machine or branch.
• The developer pushes the code to a remote repository, where a pre-commit hook triggers a build and test process on a separate server.
• The build and test process verifies that the code meets the quality standards and does not introduce any errors or conflicts with the existing code on the trunk.
• If the build and test process succeeds, the code is automatically merged into the trunk and becomes available for other developers and downstream activities.
• If the build and test process fails, the code is rejected and the developer is notified of the issues that need to be fixed before retrying the commit.

Gated commits support trunk-based development by ensuring that the trunk is always in a releasable state, which means that at least once a day, developers must integrate their changes to the trunk. This is accomplished through short-lived feature branches related to project tasks. Gated commits reduce the complexity and conflicts of merging long-lived branches, improve the quality and consistency of the code by enforcing frequent testing and validation, accelerate the delivery and deployment of new functionality by minimizing the transaction cost and risk, and foster a culture of collaboration and transparency among developers

According to the SAFe DevOps Practitioner 6.0 study guide1, one of the benefits of DevOps is better alignment between strategy and execution. DevOps is a mindset, culture, and set of technical practices that supports the integration, automation, and collaboration needed to effectively develop and operate a solution. DevOps helps break down organizational silos and develop a Continuous Delivery Pipeline (CDP) — a high-performance innovation engine capable of delivering market-leading solutions at the speed of business. By aligning strategy and execution, DevOps enables teams to deliver value to customers faster and more reliably, as well as to adapt to changing market conditions and customer needs. Therefore, better alignment between strategy and execution is one of the benefits of DevOps.

The purpose of a minimum viable product is to validate the hypothesis. A minimum viable product (MVP) is an early and minimal version of a new product or solution used to prove or disprove an epic hypothesis. An epic is a significant solution development initiative that requires the definition and approval of an MVP. An epic hypothesis is a statement that describes the expected outcome, benefit, and value of an epic. The MVP is the smallest possible solution that can be used to test the epic hypothesis with real customers or users, and to gather feedback and data. The MVP helps reduce the risk of investing in a solution that nobody wants or needs, and enables faster learning and adaptation. The MVP is not the final product or solution, but rather a starting point for further development and improvement

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, one potential outcome of the Verify activity of the Continuous Delivery Pipeline is to analyze regression testing results. This means that the Verify activity involves checking the functionality and performance of the Solution after a deployment, and comparing it with the expected results. The handbook states that "Verify is the activity of checking the functionality and performance of the Solution after a deployment, and comparing it with the expected results."1 Therefore, one of the possible outcomes of this activity is to analyze how well the Solution meets the quality standards and customer requirements.
