What is the next step?

Choose the entry point based on whether target architecture, delivery or operations matter most right now.

Clarify current state

When risks, dependencies or priorities are still unclear.

Start assessment

Plan target state

When direction is clear but architecture and delivery need detail.

Start planning

Define operations

When lifecycle, monitoring, support and responsibilities need a durable model.

Discuss operations
