Day 2 Summary

Today's Key Goals

On Day 2, we design a sequence diagram & data flow that connects the Figma screen design to the system flow, and use Codex AI as a project design reviewer to practice verifying specification consistency, tracking the scope of change impact, and archiving decisions.

Sequence diagram & DFD design: Design user-client-server-DB interaction and understand DFD concepts
Mermaid JS diagram coding: Learn how to create code-based diagrams and visualize exception handling flow
Design inconsistency detection (Task 01): Automatic checking of planning contradictions between meeting minutes, requirements definitions, and screen definitions
Change Management & Impact Analysis (Task 02): Tracking the impact of screen UI and API specifications according to requirements change requirements
Decision Tracking (Task 03): Extract completed decisions (Why) from meeting transcripts and create a checklist of pending tasks
Change impact analysis (Task 06): Analysis and reporting of UI, API, and DB impact following addition of mobile phone authentication for membership registration
Project Issue Report (Task 07): Automatic generation of weekly reports classifying risk factors from meeting minutes, change history, and pending issues list

Study Tip: Get the Right AI Chatbot “What is the difference between synchronous and asynchronous messages in a sequence diagram?” or “How do you verify contradictions between plans in Codex?” Ask the same question.

TASK 1

Consistency

Task 1. Design inconsistency detection practice

By comparing meeting minutes, requirements definitions, and screen definitions, design inconsistencies are automatically detected and an action report is created.

Task 1 Entry to the lab

TASK 2

Change Management

Task 2. Requirements change impact management practice

Automatically tracks the scope of influence of front-end screen plans and back-end API specifications according to requirements changes.

Task 2 Entry to the lab

TASK 3

Decision Tracking

Task 3. Meeting decision-making history tracking practice

Extract logs of completed business decisions and subsequent open tasks from unstructured verbal meetings and instant messenger transcripts.

Task 3 Entry to the lab

MISSION 1

Impact Analysis

Mission 1. Change impact analysis practice

We derive a report on the impact of screens, APIs, DBs, and document schemas affected by requests for additional mobile phone authentication.

Mission 1 Lab Entry

MISSION 2

Project Status

Mission 2. Practice writing project issue reports

Issue reports are automatically generated by comprehensively analyzing project original data such as meeting minutes, change history, action items, and issue lists.
