(Choose two.) Identify who is involved in each step of the delivery pipeline Perform a SWOT analysis Discuss the current state and perform an improvement analysis Measure the performance at each step Identify bottlenecks in the delivery pipeline The Release on Demand aspect enables which key business objective? Alignment Time-to-market Quality Business value Who is responsible for ensuring quality is built into the code in SAFe?

(Choose two.)You have reached the max number of allowed answers Elicit feedback Use innovation assessments Identify Metrics based on leading indicators Define the minimum viable product Use value stream mapping What is the main goal of a SAFe DevOps transformation? To align people across the Value Stream to deliver value continuously To create immutable infrastructure to avoid changes to the production environment To create a strong DevOps team with leadership support To implement an advanced tool chain to automate the entire Continuous Delivery Pipeline One goal of DevOps in SAFe is to fully automate the steps between which two pipeline activities?
