DA Lifecycle Options

Correct Answer: Market demand and business value readiness

In the Continuous Delivery: Lean lifecycle, releases to production are driven by market demand and business value readiness. This aligns with lean principles of delivering value when there is actual customer need. The focus on market demand ensures that releases are timed to maximize business impact and meet real customer needs, rather than following arbitrary schedules or technical milestones. Other options are incorrect because: Complete backlog completion is not a lean approach as it may delay value delivery. Fixed quarterly schedules contradict lean principles by forcing releases based on calendar rather than value. Technical readiness alone does not align with lean principles that prioritize business value and customer needs.

Correct Answer: Rapid feedback from stakeholders guides iterative development

In the Continuous Delivery: Lean lifecycle, rapid feedback from stakeholders that guides iterative development is the key element of the feedback loop structure. This approach aligns with Lean principles where constant feedback and adaptation are essential for continuous improvement and value delivery. The rapid feedback mechanism enables teams to make quick adjustments, minimize waste, and deliver value more effectively. The other options are incorrect because: Monthly retrospectives and quarterly planning sessions are too infrequent for a true continuous delivery approach and don't support the rapid feedback needed in Lean. Bi-weekly status meetings are too structured and formal, limiting the continuous flow of feedback that's essential in Lean practices. End-of-phase reviews suggest a waterfall-like approach with distinct phases, which contradicts the continuous flow and frequent feedback principles of Lean and Continuous Delivery.

Correct Answer: Address technical debt regularly through scheduled refactoring sessions

In the Continuous Delivery: Lean lifecycle, technical debt management should be handled through regular, scheduled refactoring sessions as part of the normal development flow. This approach aligns with Lean principles by: 1. Making debt management a continuous process 2. Preventing accumulation of waste (technical debt) 3. Maintaining a sustainable development pace 4. Supporting long-term system health The other options are incorrect because: Accumulating debt during peak phases creates waste and goes against Lean principles of continuous flow. Waiting to address debt only when it impacts performance is reactive rather than proactive, leading to increased costs and risks. Delegating to a specialized team at milestones breaks the principle of team ownership and creates unnecessary handoffs, which is against Lean practices.
