Continuous Delivery: Lean Lifecycle

Correct Answer: The team confirms technical feasibility and stakeholder alignment

In the Lean lifecycle of Continuous Delivery, the transition from exploration to construction phase occurs when the team has validated both technical feasibility and stakeholder alignment. This is the key milestone because: - It ensures the project is technically possible - Confirms stakeholder support and understanding - Provides a solid foundation for moving into actual construction The other options are incorrect because: - Complete documentation and formal sign-off are too bureaucratic and heavyweight for a lean approach - A fully detailed project plan contradicts the agile principles of progressive elaboration and adaptation - Reaching consensus on a complete architectural blueprint goes against lean principles of emergent design and iterative development

Correct Answer: Validating assumptions and hypothesis through experiments and prototypes

In the Continuous Delivery: Lean lifecycle, the exploration phase is characterized by validating assumptions and hypotheses through experiments and prototypes. This is fundamental to the lean approach, as it emphasizes learning and validation before making significant investments. The correct answer aligns with lean principles of reducing waste by testing ideas early and gathering feedback quickly through experimentation. The other options are incorrect because: - Creating detailed upfront requirements analysis contradicts the lean principle of iterative development and learning - Producing comprehensive technical specifications early goes against the lean approach of progressive elaboration - Extensive manual testing procedures are not characteristic of the exploration phase, which focuses on quick validation and learning

Correct Answer: To incrementally build and test the solution

In the Continuous Delivery Lean lifecycle, the primary objective of the construction phase is to incrementally build and test the solution. This aligns with lean principles by:

1. Supporting continuous flow of value
2. Enabling fast feedback cycles
3. Allowing quick adaptation to changes
4. Minimizing waste through incremental development

The other options are incorrect because:

- Establishing comprehensive architectural guidelines upfront contradicts lean principles of evolutionary design and adaptation
- Developing extensive documentation and finalizing requirements upfront goes against the agile and lean values of responding to change
- Focusing on stakeholder management and business case refinement is more relevant to inception phase activities, not construction phase

The lean approach emphasizes building small increments, testing frequently, and continuously delivering value rather than creating comprehensive upfront documentation or specifications.
