    Scenario 15 – Architecture Audit and Design Integrity Risk

    Scenario Context

    Following the instability introduced by recent resource expansion and defect patterns, C-Bay’s internal architecture team conducted a targeted audit of the Reckon system.

    The audit focused on:

    • Synchronization Engine design

    • Data handling consistency

    • Module interaction patterns

    • Adherence to architectural guidelines

    The audit results have now been shared.

    While the system is operational, several architectural inconsistencies have been identified.

    These do not currently block functionality.

    However, they may affect long-term maintainability, scalability, and integration stability.

    Email from Julie Rama

    Subject: Architecture Review Feedback – Request for Alignment

    Hi,

    We received the feedback from your internal architecture review and wanted to align on next steps.

    1. Summary of Findings

    The review identified the following:

    • Inconsistent handling of synchronization logic across modules

    • Variations in data validation patterns

    • Some divergence from originally documented architectural guidelines

    • Redundant logic implemented in multiple components

    From our perspective:

    • These do not affect current functionality

    • They do not block RC1 or immediate usage

    • They are typical of iterative development where refinement occurs over time

    2. Vendor Position

    We believe the system remains:

    • Functionally stable

    • Deliverable within current timeline

    • Suitable for iterative improvement in future cycles

    Refactoring at this stage would:

    • Require additional development effort

    • Increase QA cycles

    • Potentially impact near-term delivery commitments

    3. Request

    We need guidance on how you would like to proceed:

    • Address architectural inconsistencies immediately

    • Defer refactoring to future iterations

    • Prioritize only high-risk areas

    We want to ensure alignment with your expectations.

    Best,
    Julie

    Attachment A – Architecture Audit Summary

    Area Observation Risk Level
    Synchronization Logic Inconsistent implementation across modules High
    Data Validation Different validation rules applied in similar contexts Medium
    Code Duplication Redundant logic across components Medium
    Architecture Compliance Partial deviation from original design patterns Medium

    Attachment B – Impact Considerations

    • Refactoring effort estimated at:

      • Development: +10–12%

      • QA: +8–10%

    • Potential schedule impact: 1–2 weeks

    • Risk if not addressed:

      • Increased maintenance complexity

      • Future defect risk

      • Scalability limitations

    Student Assignment

    You are the Project Manager at C-Bay.

    An internal architecture audit has revealed:

    • Design inconsistencies

    • Deviation from standards

    • Potential long-term risks

    However:

    • The system is currently functional

    • No immediate delivery blocker exists

    • Refactoring will impact cost and schedule

    You must determine:

    • Whether to intervene immediately

    • Whether to defer architectural cleanup

    • How to balance short-term delivery vs long-term system integrity

    • How to maintain vendor alignment while addressing internal concerns

    Prepare a formal written response to Julie Rama.

    Required Submission Structure

    Your memorandum must include:

    1️⃣ Executive Position

    • Is the system acceptable for current release?

    • Is architectural inconsistency a critical issue?

    • Should action be taken now or later?

    2️⃣ Architecture Assessment

    • How serious are the identified inconsistencies?

    • Do they represent technical debt or structural risk?

    • Which issues are critical vs tolerable?

    3️⃣ Refactoring Strategy

    • Should refactoring be initiated immediately?

    • Should it be phased across future iterations?

    • Should only high-risk areas be addressed now?

    4️⃣ Schedule & Budget Impact

    • Is a 1–2 week delay acceptable?

    • Is additional cost justified?

    • Should delivery timeline be protected instead?

    5️⃣ Risk Assessment

    Identify and evaluate:

    • Long-term technical debt risk

    • Maintainability risk

    • Scalability risk

    • Immediate delivery risk

    Assign likelihood and impact.

    6️⃣ Internal Alignment Strategy

    • How will you address internal architecture concerns?

    • How will you communicate decisions to leadership?

    • How will you maintain confidence in the project?

    7️⃣ Directive to ZynoxDev

    Provide a clear directive, such as:

    • Proceed with RC1 and defer refactoring

    • Address high-risk architectural issues immediately

    • Develop phased refactoring plan

    • Provide detailed architecture alignment roadmap

    • Conduct focused redesign of synchronization module

    Learning Focus

    Scenario 15 introduces:

    • Technical governance beyond surface metrics

    • Balancing short-term delivery vs long-term system health

    • Managing internal expert feedback

    • Recognizing technical debt formation

    • Making trade-offs under architectural uncertainty

    Students must demonstrate:

    • Technical awareness (without coding)

    • Strategic decision-making

    • Long-term thinking

    • Balanced judgment

    Key Insight

    A system can be:

    • Functionally correct

    • Yet structurally fragile

    The Project Manager must decide:

    When to fix
    When to defer
    When to accept risk

    This scenario represents a transition from:

    “Is the project delivering?”

    to:

    “Is the system sustainable?”
