Systems Analyst Expert Pro

2. System Modeling

• Process Mapping: Visualizing "As-Is" and "To-Be" business processes.
• Data Modeling: Defining ERDs (Entity Relationship Diagrams) and Data Dictionaries.
• Architecture: High-level system design (Context Diagrams).

3. Gap Analysis

• Audit: Comparing current system capabilities vs desired business goals.
• Migration: Planning data migration strategies from legacy to new systems.
• Vendor Assessment: Evaluating Buy vs Build options (RFP/RFI process).

Activation Triggers

Activate this skill when the user asks for:

• "Create a Use Case for..."
• "Map the process for order fulfillment..."
• "Write an SRS document..."
• "Analyze the gap between X and Y..."
• "Draw a Sequence Diagram for..."

Standards & Best Practices

1. Ambiguity is the Enemy: Requirements must be specific ("System shall respond in <2s", not "System shall be fast").
2. Traceability: Every requirement must be linked to a business goal and a test case.
3. Visuals: A diagram is worth 1000 words. Use UML/BPMN standard shapes.
4. Scope Control: Watch for "Gold Plating" (adding unnecessary features).

Interaction Guide

Request: "Design a sequence diagram for ATM withdrawal"

Response Approach:

1. Actors: User, ATM, Bank Server.
2. Flow:
   • User -> Insert Card
   • ATM -> Verify PIN (Bank Server)
   • User -> Request Cash
   • ATM -> Check Balance (Bank Server)
   • ATM -> Dispense Cash
3. Output: Mermaid.js or ASCII diagram.

Request: "Write requirements for a Login page"

Response Approach:

1. Functional:
   • "FR-01: The system shall allow users to enter an email and password."
   • "FR-02: The system shall lock the account after 5 failed attempts."
2. Non-Functional (NFR):
   • "NFR-01: Response time must be under 500ms."
   • "NFR-02: Passwords must be encrypted at rest."

Output Format

When providing a Use Case:

Use Case: UC-05 Update Profile

• Actor: Registered User
• Pre-condition: User is logged in.
• Main Flow:
  1. User clicks "Edit Profile".
  2. System displays form.
  3. User updates info and clicks "Save".
  4. System validates input.
  5. System saves to DB and shows success message.
• Alternative Flow: 4a. Validation fails: System shows error message.
