Plan: Update BA to Data Analyst Skills Roadmap

This plan outlines the changes required to refine the “BA to Data Analyst” skills roadmap on ba-to-data.html. It includes adding a seventh skill group for Data Governance & MDM, de-duplicating modeling terminology, and incorporating strategic skills like KPI storytelling and environment strategy.

1. Content & Terminology Updates

• Data Requirements & Mapping (formerly BA Artifacts):
  • Rename “Data Modeling” to “Conceptual Data Models” to distinguish from analytical modeling.
• Analytical Data Modeling (formerly Data Modeling):
  • Update group name to clarify the focus on warehouse design.
• SQL & Analytics:
  • Add “KPI Documentation & Storytelling”.
  • Add “Statistical Thinking” to the visual mind map.
• Data Platforms:
  • Add “Environment Strategy (Dev/Prod)”.
• ETL & ELT:
  • Add “Data Quality & Testing” to the visual mind map.
• Data Governance & MDM (New Group):
  • Items: Master Data Management (MDM), Reference Data, Data Quality Framework, Data Privacy & Ethics, Data Stewardship, Metadata Management.

2. Visual Mind Map Re-design (SVG & CSS)

• Layout Change: Shift from a 3/3 balanced layout to a 3-left / 4-right layout to accommodate the 7th branch.
• Coordinates (Right Side):
  • Analytical Data Modeling (⑤): Move to top: 80px.
  • Data Requirements & Mapping (①): Move to top: 300px.
  • Data Governance & MDM (⑦): Add at top: 520px (Color: #A855F7).
  • SQL & Analytics (②): Move to top: 740px.
• Sub-node Spacing: Adjust vertical spacing from 40px to 35px to fit more items within the height constraints.
• SVG Paths: Update cubic bezier paths to connect the center node to the 4 right-side branches.

3. Section Descriptions (HTML)

• Update all existing <div class="branch-section"> headers and bullet points.
• Add the new Data Governance & MDM section with detailed descriptions of MDM, Reference Data, and Stewardship.
• Refine the SQL & Analytics section to include the importance of KPI storytelling and statistical significance.

4. Verification Plan

• Visual Check: Open the updated HTML in a browser to ensure the mind map lines connect correctly and text does not overlap.
• Content Check: Verify that “Data Modeling” is now clearly split into “Conceptual” (BA side) and “Analytical” (Engineering side).
• Responsive Check: Ensure the horizontal scroll on mobile still functions correctly with the 7 branches.
