Structured Problem Solving

Some problems are too complex for:

Prompt → Answer

The application may need a sequence of steps.

For example:

Analyze a customer complaint, retrieve the order, check refund policy, calculate eligibility, and generate a response.

Possible workflow:

User Request
     ↓
Understand Task
     ↓
Retrieve Order
     ↓
Check Policy
     ↓
Evaluate Eligibility
     ↓
Calculate Refund
     ↓
Generate Response

ReAct combines reasoning/planning with actions.

Conceptually:

Think / Decide
      ↓
Act
      ↓
Observe Result
      ↓
Decide Next Step
      ↓
Act Again

Example:

Question
   ↓
Need customer information
   ↓
Call CRM tool
   ↓
Customer data returned
   ↓
Need order information
   ↓
Call order API
   ↓
Order returned
   ↓
Generate answer

For implementation, you should think in terms of structured reasoning steps and observable actions, not exposing private chain-of-thought.

AWS Step Functions can orchestrate multi-step workflows.

    Lambda     Bedrock     Lambda
    Step 1      Step 2      Step 3

It can manage:

• sequencing
• branching
• retries
• waiting
• state
• failure handling
• human approval

If the question says:

"Implement a multi-step workflow with explicit states and transitions"
