Value stream mapping metrics include calculations of three metrics: total process time, rolled % complete and accurate, and activity ratio. Value stream mapping is a lean technique to analyze, design, and manage the flow of materials and information required to bring a product or service to a customer. It uses a system of standard symbols to depict various work streams and information flows, and to identify value-adding and non-value-adding activities. Value stream mapping metrics are used to measure the efficiency and effectiveness of a production process, and to identify areas for improvement. Some of the common value stream mapping metrics are:

Total process time: the sum of the process times for all the activities in the value stream. It measures how long it takes to complete a unit of work from start to finish.

Rolled % complete and accurate: the percentage of units that are completed and accurate at each step of the value stream, multiplied across all the steps. It measures the quality and reliability of the process output.

Activity ratio: the ratio of value-adding time to total lead time.It measures the proportion of time spent on activities that create value for the customer, versus activities that do not

Answer : B

The reason why it is important to take a structured approach to analyze problems in the delivery pipeline is that it helps ensure that actual causes of problems are addressed, rather than symptoms. A structured approach to problem analysis involves following a systematic and logical process to identify, define, and understand the root causes of a problem, and to propose and evaluate possible solutions. A structured approach can help avoid jumping to conclusions, making assumptions, or applying band-aid fixes that do not solve the underlying issues. A structured approach can also help involve the relevant stakeholders, collect and analyze data, prioritize and categorize problems, and communicate and document the findings and recommendations.Some examples of structured approaches to problem analysis are the 5 Whys, the fishbone diagram, the Pareto chart, and the PDCA cycle

Answer : A

The statement that is true about DevOps is that it enables low-risk releases and fast recovery with fast fix-forward. 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 aims to deliver value to customers whenever there is a business need, by applying the principles of continuous delivery, continuous integration, continuous deployment, and release on demand. DevOps also embraces a culture of learning and experimentation, where failures are opportunities for improvement and feedback. DevOps enables low-risk releases by breaking down large and complex changes into smaller and more frequent batches, which are easier to test, deploy, and rollback if needed. DevOps also enables fast recovery by implementing practices such as monitoring, alerting, incident response, and disaster recovery, which help to detect and resolve issues quickly, minimize the impact of failures, and restore normal operations as soon as possible. DevOps also supports the fast fix-forward approach, which means fixing errors in production by deploying new code, rather than rolling back to a previous state.This approach reduces the risk of introducing new errors, preserves the value of the new functionality, and accelerates the learning cycle

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 : D

The primary goal of the Stabilize activity is to avoid unplanned outages and security breaches. The Stabilize activity is part of the Release on Demand aspect of the CDP in SAFe DevOps, which ensures the solution is working well from a functional and nonfunctional requirements (NFR) perspective. The Stabilize activity involves practices such as monitoring, logging, alerting, incident response, and disaster recovery.These practices help to detect and resolve issues quickly, minimize the impact of failures, and restore normal operations as soon as possible
