Answer : A, E

When preparing a DevOps backlog, prioritizing features using WSJF includes two factors: cost of delay and duration/job size. WSJF stands for Weighted Shortest Job First, which is a prioritization model used to sequence work for maximum economic benefit. WSJF is estimated as the relative cost of delay divided by the relative job duration. Cost of delay is the money lost by delaying or not doing a job for a specific time. It is a measure of the economic value of a job over time. Job duration is the time it takes to complete a job. Jobs that can deliver the most value in the shortest duration provide the best economic return.WSJF also considers other factors that contribute to the cost of delay, such as user and business value, time criticality, and risk reduction and/or opportunity enablement

Answer : A

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, value flows through Continuous Integration in the Continuous Delivery Pipeline. This aspect involves merging code changes from multiple developers into a shared repository and running automated tests to ensure quality and functionality.The handbook states that 'Continuous Integration is the process of merging code changes from multiple developers into a shared repository and running automated tests to ensure quality and functionality.'1Therefore, Continuous Integration enables teams to deliver value faster and more reliably by reducing integration errors and conflicts.

Answer : B

According to the SAFe DevOps Practitioner 6.0 study guide1, when prioritizing improvement items, the steps with short Active Time and high %C&A in the future-state map should be the main focus. Active Time is the amount of time a step spends on performing work, while %C&A is the percentage of capacity utilization of a step. The future-state map shows how the Value Stream will look like after implementing improvements, based on customer feedback and business value. The improvement items are ranked by their impact on flow efficiency, customer satisfaction, and business agility. The steps with short Active Time and high %C&A in the future-state map indicate that they are bottlenecks or waste sources that need to be eliminated or reduced as soon as possible. Therefore, they should be prioritized for improvement actions.

Answer : D

According to the SAFe DevOps Practitioner 6.0 study guide1, root cause analysis is a technique that helps identify and eliminate the underlying causes of problems or defects in the Solution. Root cause analysis can be used to address impediments to continuous delivery by finding and fixing the root causes of issues such as delays, rework, waste, and errors. Root cause analysis can be performed during various phases of the PI, such as during the Iteration Retrospective, during the management review and problem-solving portion of PI Planning, or during Inspect & Adapt (I&A). However, the most effective time to use root cause analysis is during I&A, which is a significant event held at the end of each PI, where the current state of the Solution is demonstrated and evaluated. Teams then reflect and identify improvement backlog items via a structured problem-solving workshop. The result is a set of improvement backlog items that go into the ART Backlog for the next PI Planning event. Therefore, root cause analysis can help teams address impediments to continuous delivery by improving their performance and quality in the next PI.

Answer : A

According to the SAFe DevOps Practitioner 6.0 study guide1, continuous deployment enables release continuously. Continuous deployment is an aspect of the Continuous Delivery Pipeline that automates the migration of new functionality from a staging environment to production, where it is made available for release. Continuous deployment allows teams to deploy small, incremental changes to production continually, enabling them to respond to market opportunities with the highest possible value in the shortest sustainable lead time. Continuous deployment also helps teams to reduce the risk of deploying faulty or incomplete code, as well as to optimize the performance and resource consumption of the system. Therefore, continuous deployment enables release continuously, which is a key business objective for delivering value to customers faster and more reliably.
