Day 14 — Design an End-to-End AI Solution

Purpose: Combine prompting, context, retrieval, tools, evaluation, privacy and human gates into one defensible design.

Source/build status: Integration day.

Learning outcomes

• Translate a user problem into an end-to-end AI system with explicit success measures.
• Justify when prompting, retrieval, tools or automation are actually needed.
• Design evaluation, permissions, logging, escalation and human ownership into the architecture.
• Test the design against realistic failure and misuse cases before calling it viable.

Core lesson — Design an End-to-End AI Solution

An end-to-end AI solution is a controlled system, not a model surrounded by features. Begin with users, outcome and success measure; identify approved knowledge and data; choose prompting, retrieval or tools only where needed; define evaluation, permissions, logging, escalation and human ownership; then test the complete workflow against realistic failure cases.

Worked example

Design a vendor-neutral internal policy assistant: authorized users → current approved policy corpus → retrieval → grounded generation → visible source references → evaluation checks → access controls → escalation for insufficient or conflicting evidence → logging → accountable policy owner. Every component must solve a defined need.

Teaching / video direction

Build the architecture left-to-right, then run three failure cases through it: stale source, insufficient evidence and unauthorized request. Close by explaining that Day 15 is not another theory lesson—the learner must demonstrate an integrated solution and its evidence.

Hands-on practical exercise

1. Choose a low-risk knowledge or workflow problem and define users, outcome and success measure.
2. Draw the end-to-end flow from input through evidence/model/tool steps to final outcome.
3. For every component, write why it exists and what happens if it fails.
4. Add access controls, evaluation, logging, escalation and accountable ownership.
5. Run at least three failure cases through the design, including insufficient evidence and unauthorized use.
6. Revise the architecture based on the failures and record the changes.

Knowledge check

1. Why is a model alone not an end-to-end solution?
2. When is retrieval justified?
3. Why must escalation behavior be designed before deployment?
4. What should logs make possible?
5. Why test unauthorized and insufficient-evidence cases?
6. What evidence would show the solution improves the target task?

Assessment and remediation contract

The scored daily quiz uses 10 questions; 7/10 (70%) is a pass. Missed concepts map to exact lesson anchors for targeted remediation, including on a passing attempt. Attempts 1–9 below threshold return to remediation and a fresh eligible question set; an unsuccessful tenth attempt restarts the day in a new learning cycle while preserving history. The 50-question validated bank is a learner-release gate and will be scaled only after the Day 1 runtime passes acceptance.

Teaching / video script — 6–8 minute target

Open: Start with the worked scenario, not a generic definition: Design a vendor-neutral internal policy assistant.

Teach: Demonstrate the method visibly: Define users/outcome → approved knowledge → retrieval → generation → source display → evaluation → permissions → escalation → logging → human ownership. Pause at the judgment point and explain why the system should not simply continue on autopilot: Every component needs a reason. Include failure modes, fallback behavior and a way to test whether the system actually improves the target task.

Practice bridge: Ask the learner to reproduce the method on a different low-risk example, mark the verification/control step, and explain the reason for it.

Close: Day 15: demonstrate practical mastery in the capstone.

Production / QA notes

• Use the worked scenario as the primary visual sequence; avoid generic AI-brain imagery.
• Keep terminology vendor-neutral and define unavoidable technical terms in context.
• Do not equate fluent output with verified truth or AI assistance with autonomous authority.
• Before learner release, fact-check the final lesson and validate every scored item against explicit teaching.
