What should be measured in a CALMR approach to DevOps?
The correct answer is D. Flow, quality, and value should be measured in a CALMR approach to DevOps. The CALMR approach to DevOps is a mindset that guides the ARTs toward achieving continuous value delivery by enhancing culture, automation, lean flow, measurement, and recovery. Measurement is one of the key elements of the CALMR approach, as it provides data and feedback to monitor and improve the performance and outcomes of the solution delivery process. Measurement involves collecting and analyzing metrics that reflect the flow, quality, and value of the solution, such as:
Flow metrics -- Flow metrics measure the efficiency and reliability of the delivery process, such as lead time, cycle time, throughput, work in progress, and flow efficiency. Flow metrics help to identify and eliminate waste and bottlenecks in the value stream, and to optimize the flow of value to the customer.
Quality metrics -- Quality metrics measure the functionality and stability of the solution, such as defect rate, defect density, defect leakage, mean time to detect, mean time to resolve, and test coverage. Quality metrics help to ensure that the solution meets the functional and nonfunctional requirements and standards, and to detect and resolve any issues or defects as early as possible.
Value metrics -- Value metrics measure the outcomes and benefits of the solution, such as customer satisfaction, retention, engagement, revenue, and net promoter score. Value metrics help to evaluate the validity of the hypotheses and assumptions about the customer value proposition, and to guide the decision making and prioritization of the features12
