SAFe-DevOps Dumps with Practice Exam Questions Answers

After the team maps the steps of the current state value stream during value stream mapping, the next two steps are to measure the performance at each step and calculate the activity ratio. Measuring the performance at each step involves collecting data on cycle time, lead time, process time, wait time, defect rate, and other relevant metrics. This helps to identify the sources of waste, delays, and inefficiencies in the value stream. Calculating the activity ratio involves dividing the total process time by the total lead time and multiplying by 100. This gives the percentage of time that is spent on value-adding activities versus non-value-adding activities. The activity ratio helps to quantify the flow and identify opportunities for improvement

According to the SAFe DevOps Practitioner 6.0 study guide1, the Continuous Delivery Pipeline (CDP) represents the workflows, activities, and automation needed to guide new functionality from ideation to an on-demand release of value. The CDP consists of four aspects: Continuous Exploration (CE), Continuous Integration (CI), Continuous Deployment (CD), and Release on Demand. The CDP enables organizations to deliver new functionality to users far more frequently than traditional processes. The first step in the CDP is Continuous Exploration, which focuses on creating alignment on what needs to be built. In CE, design thinking ensures the enterprise understands the market problem or customer need and the solution required to meet that need. It starts with a hypothesis of something that will provide value to customers. Therefore, an idea marks the beginning of the CDP in CE.

The statement that describes the Lean startup lifecycle is: Define the hypothesis, build a minimum viable product (MVP), continuously evaluate the MVP while implementing additional Features until WSJF determines work can stop. The Lean startup lifecycle is a highly iterative build-measure-learn cycle that has proven to be effective in optimizing the economic value of strategic investments. It consists of three learning milestones: MVP, tune the engine, and pivot or persevere. The MVP is the smallest possible experiment that allows the enterprise to test the assumptions and hypotheses of an epic or a large initiative. The tune the engine phase involves quickly adjusting and moving towards the goal based on the data and feedback gathered from the MVP. The pivot or persevere phase involves deciding whether to deliver additional value or move on to something more valuable based on the validated learning. The Lean startup lifecycle is supported by the SAFe Lean Startup Cycle, which provides guidance and tools for applying the Lean startup principles in the context of SAFe. The SAFe Lean Startup Cycle includes the following steps:

• Define the hypothesis – This step involves creating an epic hypothesis statement that defines the initiative, its expected benefits, and its leading indicators.
• Build the MVP – This step involves defining, building, and deploying the MVP that tests the hypothesis and delivers the minimum amount of value to the customer.
• Evaluate the MVP – This step involves measuring and analyzing the results of the MVP against the leading indicators and the hypothesis.
• Implement additional Features – This step involves developing and delivering additional features or capabilities that enhance the value proposition of the initiative, based on the learning from the MVP.
• WSJF determines work can stop – This step involves using the Weighted Shortest Job First (WSJF) prioritization method to determine whether the initiative has delivered enough value to the customer and the enterprise, or whether it needs more investment or termination3

Innovation accounting stresses the importance of avoiding vanity metrics. Vanity metrics are metrics that look good on paper but do not reflect the true value or impact of an innovation. Examples of vanity metrics include the number of downloads, page views, followers, or likes, which may not indicate whether the users are actually engaged, satisfied, or loyal to the product or service. Vanity metrics can be misleading, deceptive, or irrelevant, and can cause the enterprise to waste time and resources on pursuing the wrong goals or strategies. Innovation accounting, on the other hand, is a term coined by Eric Ries in his book The Lean Startup, which describes a process of measuring and learning from the outcomes of innovation experiments. Innovation accounting involves defining the hypothesis, building the minimum viable product (MVP), and evaluating the results using actionable metrics. Actionable metrics are metrics that demonstrate the cause and effect relationship between the actions taken and the outcomes achieved. Examples of actionable metrics include the conversion rate, retention rate, revenue per customer, or customer satisfaction score, which can indicate whether the product or service is delivering value to the customer and the enterprise. Actionable metrics can help the enterprise to validate or invalidate the hypothesis, and to decide whether to pivot or persevere with the innovation78

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, the metric that reflects the quality of output at each step in the Value Stream is Percent Complete and Accurate (%C&A). This metric measures the relative cost of delay divided by the relative job duration, which indicates how efficiently the value stream delivers value to customers. The handbook states that "Percent Complete and Accurate (%C&A) is a metric that measures the relative cost of delay divided by the relative job duration."1 Therefore, %C&A helps teams identify and eliminate any waste or inefficiencies in their value stream.
