    Diagnosing Root Causes: Uncovering What’s Beneath the Risk

    Scenario Briefing

    MEMO
    To: SMDC Risk Strategy Team
    From: Kira L. Joshi, Chief Operating Officer, SMDC
    Date: Week 6 – Risk Remediation Planning
    Subject: Request for Root Cause Analysis on Persisting High-Impact Risk Area

    Team,

    After reviewing the control checklists you delivered last week, one concern has come up repeatedly: we seem to be treating symptoms rather than underlying conditions. I’ve heard feedback from Engineering, Clinical, and Product that our dashboards, alerts, and processes still show signs of tension, even where controls exist. In several sprint retrospectives, we’ve captured issues that sound like this:

    “Too many alerts are misfiring.”
    “Data syncs inconsistently across devices.”
    “Users aren’t responding to critical insights.”
    “We’re fixing the same bugs repeatedly.”

    These are not isolated failures. These are signs that we haven’t reached the root.

    I need your help to trace one high-impact risk theme all the way down—to find the underlying causes, assumptions, or systemic breakdowns that keep fueling it. Use both visual and narrative cause analysis tools to show the difference between a surface symptom and a structural problem.

    We’ll use your output to decide:

    You have permission to go deep. The more uncomfortable and unspoken the root cause, the more valuable your analysis.

    Let’s move from observation to transformation.

    Action Strategy

    Purpose of This Milestone

    This milestone introduces you to root cause analysis—the practice of tracing risk events back to their origin points, behavioral patterns, or systemic design flaws.

    Most risk plans fail not because risks were invisible—but because teams only addressed surface symptoms. Without root cause work, risk plans get stuck in cycles of band-aids and rework.

    You will use two integrated tools:

    You’ll learn how to:

    Your final product is a structured diagnostic that prepares your team for deep, cross-functional redesign or escalation.

    Step-by-Step Guide

    Step 1: Choose a Risk Theme or Event to Diagnose

    Start by reviewing your previous milestones. Choose one high-priority risk theme or event that remains unresolved or difficult to control. Examples include:

    Choose a theme that:

    Write a short paragraph summarizing:

    • What breakdown or failure it represents

    Step 2: Build the Cause Tracer Diagram

    Use the Fishbone/Ishikawa structure to visually organize potential root causes under thematic branches. Use at least four of the following cause categories:

    For each branch, list at least two specific contributing factors. Push past the obvious.

    Instead of “bad design,” ask:

    This is a team learning artifact, not a blame diagram.

    Step 3: Apply the 5 Whys Technique to a Single Symptom

    Choose one concrete risk symptom from your theme—e.g., “Clinicians ignore trend alerts”—and apply the 5 Whys method to trace its logic downward.

    Ask “Why did this happen?”
    Then for each answer, ask “Why?” again, five levels deep.

    Example:

    This method helps surface:

    Record this 5 Whys sequence as part of your deliverable.

    Step 4: Synthesize Findings into a Root Cause Summary

    Write a narrative that explains:

    • What would need to change to prevent recurrence
    • What risks remain even if a root cause is addressed

    Use this summary to help leadership understand:

    Your Deliverable

    Part 1: Cause Tracer Diagram

    Includes:

    Format: Table or diagram, typed or drawn clearly.

    Part 2: 5 Whys Sequence

    Part 3: Root Cause Summary (1–2 pages)

    Critical Reflection

    Write 200–300 words on:

    Quality Control Review

    • Clear problem or risk theme defined
    • Fishbone-style cause diagram created with specificity
    • 5 Whys sequence completed with logical depth
    • Summary includes explanation and insight—not just description
    • Reflection addresses team dynamics and system design
    • File is formatted for reuse in Milestone 6 or 7
    • All components clearly labeled and submitted together

    Final Wrap-Up and Submission

    Submit your full diagnosis bundle via your assigned LMS portal, team folder, or instructor pathway. You will reuse this root cause work in:

    This milestone teaches you how to go beyond the obvious—and help others see what needs to change.
