Case Study 1: High-Visibility Customer Business Review & Quality Performance Presentation

Project Type: Customer Communication | Quality KPI Reporting | Supplier Relationship Management | Continuous Improvement Communication

Overview

During a high-visibility customer business review, I presented the quality performance portion of the meeting with little advance notice. The review covered current quality performance, customer return activity, open quality notifications, corrective action status, and ongoing improvement initiatives.

This presentation required more than reporting metrics. I had to connect quality data to active improvement work, explain supplier performance clearly, and represent internal quality, operations, and management priorities in a professional customer-facing setting.

Problem

Customer business reviews require quality performance to be communicated accurately, confidently, and transparently. The challenge was to present current quality performance in a way that addressed customer concerns while also showing active ownership of improvement efforts.

The review included discussion of customer return activity, quality notifications, liability status, corrective action progress, and improvement initiatives tied to production and inspection performance.

Actions Taken

  • Presented the April 2026 quality scorecard directly to the customer.
  • Communicated current customer return activity and quality notification status.
  • Reviewed improvement initiatives connected to First Pass Yield, inspection consistency, and defect reduction.
  • Discussed ongoing biweekly customer alignment meetings used to track open quality notifications, RCCA status, and collaborative improvement actions.
  • Connected internal Yellow Belt process improvement work to broader production and quality performance goals.
  • Explained efforts to improve visual inspection consistency by aligning internal practices with customer visual inspection requirements.
  • Responded to customer questions in real time while maintaining a professional, technically grounded discussion.
  • Represented internal quality, production, operations, and management interests during the review.

Collaboration & Stakeholder Alignment

This review involved customer representatives, internal management, quality leadership, operations, production, and business stakeholders. The work presented was supported by cross-functional collaboration across quality, manufacturing, inspection, and process improvement teams.

The review also reflected ongoing customer collaboration through regular alignment meetings focused on open quality notifications, RCCA activity, and improvement actions. This helped keep both the company and customer aligned on current performance, risks, and next steps.

Result / Impact

The presentation supported customer confidence by showing that quality performance was being actively monitored, communicated, and improved. The discussion highlighted ongoing improvement work, including First Pass Yield focus, visual inspection standardization, customer return tracking, and Yellow Belt process improvement activity.

The review demonstrated my ability to translate quality data into a clear customer-facing message, connect metrics to action, and represent cross-functional improvement work in a high-visibility setting.

Skills Demonstrated

Customer-facing communication; quality KPI reporting; business review presentation; supplier relationship management; corrective action communication; RCCA status tracking; First Pass Yield improvement; visual inspection standardization; continuous improvement; cross-functional alignment; leadership under pressure.

Case Study 2: Marking Verification System Approval

Project Type

Quality System Improvement | Customer Requirement Compliance | Capital Equipment Justification

Overview

A customer marking approval became a gating item for First Article Inspection Report approval. The existing process could not consistently verify 2D Data Matrix markings to the required standard, which created risk for delayed shipments, rejected FAIRs, and potential customer returns.

I led the technical investigation into the marking verification requirements, reviewed applicable customer and industry requirements, coordinated with equipment vendors, and supported the justification for a complete verification solution.

Problem

The site had a Keyence XR-series verifier, but the existing setup did not include the external lighting configuration needed to consistently achieve acceptable verification results. Several marking verification reports were rejected by the customer because they did not meet the expected verification format and lighting conditions.

Actions Taken

  • Reviewed applicable marking and verification requirements.
  • Compared customer requirements against internal procedures and industry references.
  • Coordinated an onsite equipment demonstration with the vendor.
  • Verified that external coaxial lighting produced an acceptable grade.
  • Collected objective evidence showing the setup change resolved the verification issue.
  • Supported equipment justification using rejected reports, customer approval evidence, cost avoidance, and business risk.

Result

The updated verification method produced an accepted verification report and allowed the customer marking approval to move forward. This reduced the risk of future marking escapes, improved FAIR approval readiness, and supported stronger alignment between engineering requirements, inspection capability, and customer expectations.

Skills Demonstrated

  • Technical requirement interpretation
  • Customer quality communication
  • Equipment justification
  • Risk-based decision making
  • Process improvement
  • Cross-functional coordination

Case Study 3: Polishing Process Improvement

Project Type

Legacy Process Improvement | Inspection Alignment | Bottleneck Reduction

Overview

A long-standing polishing process had evolved into an overly restrictive practice that was creating unnecessary production bottlenecks. Parts were being polished beyond the actual drawing and inspection requirements, which increased labor time and created confusion between production, inspection, and customer expectations.

I reviewed the internal procedure, router requirements, and inspection flowdown to determine what was actually required versus what had become legacy practice.

Problem

The process had been treated as a customer-specific requirement for many years, even though the router operation already defined what needed to be polished. The procedure also did not clearly flow down the applicable internal inspection requirements. This created unnecessary work and reinforced inconsistent expectations.

Actions Taken

  • Reviewed the polishing procedure against actual router and inspection requirements.
  • Removed customer-specific requirements that were not supported by the current flowdown.
  • Added the correct internal inspection procedure references.
  • Identified and dispositioned over 30 jobs where the polishing operation was not required.
  • Created an internal action tracker to manage follow-up actions.
  • Communicated the improvement carefully during customer review discussions without creating unnecessary concern.

Result

The improvement reduced unnecessary polishing activity, clarified inspection expectations, and helped align production, quality, and customer communication. It also supported a shift away from a “make it perfect by habit” legacy process toward a requirement-based manufacturing approach.

Skills Demonstrated

  • Procedure review and revision
  • Lean thinking
  • Bottleneck reduction
  • Manufacturing quality alignment
  • Customer communication
  • Change management

Case Study 4: FAIR Planning and Contract Review Integration

Project Type

Quality System Improvement | Process Automation Concept | Cross-Functional Alignment

Overview

First Article Inspection Reports require accurate planning, traceability, and documentation. I identified an opportunity to connect contract review outputs directly to FAIR planning activities to reduce duplicate effort and improve accuracy.

The contract review team already creates an indented bill of material breakdown that includes special processes, quality clauses, and requirement flowdown. I recognized that this information closely aligns with the structure needed to prepare AS9102 Forms 1 and 2.

Problem

FAIR planning and contract review were being handled as separate processes, even though they used much of the same information. This created duplicated work, increased the chance of missed requirements, and delayed FAIR preparation until later in the production cycle.

Actions Taken

  • Compared contract review outputs to AS9102 FAIR documentation needs.
  • Identified overlap between contract review data and FAIR Forms 1 and 2.
  • Proposed a process where contract review outputs could help pre-populate FAIR planning records.
  • Recommended linking purchase order review, contract review, and FAIR planning into one more connected workflow.
  • Suggested value-stream sorting and export functions to make the process easier for users across departments.
  • Used process improvement thinking to frame the opportunity as a system-level improvement rather than a single-department fix.

Result

The proposed improvement created a clearer path toward reducing duplicate review activity, improving FAIR readiness, and making requirement flowdown easier for production, quality, and customer-facing teams to understand. The concept supported better alignment across contract review, engineering, quality, and inspection planning.

Skills Demonstrated

  • AS9102 FAIR planning
  • Process mapping
  • Systems thinking
  • Cross-functional collaboration
  • Quality management system improvement
  • User-focused process design

Case Study 5: Pressure Test / Casting Salvage Investigation

Project Type

Nonconformance Management | Customer Approval Strategy | Product Risk Containment

Overview

A pressure test issue affected high-value aerospace hardware. The condition required immediate containment, technical review, and customer communication to determine the proper path forward.

I supported the investigation by ensuring the issue was clearly documented, aligned to applicable visual and pressure test criteria, and communicated in a way that allowed the customer to evaluate a practical rework or salvage path.

Problem

The affected hardware represented significant value and schedule risk. Shipping without proper review was not acceptable, but scrapping without full technical evaluation could have created unnecessary cost and material loss.

Actions Taken

  • Supported containment of affected product.
  • Reviewed the condition against applicable visual and pressure test criteria.
  • Helped frame the customer nonconformance language clearly and technically.
  • Coordinated with internal teams to support a possible rework path.
  • Maintained focus on objective evidence, product risk, and customer approval requirements.

Result

The issue was managed through the proper customer approval path, helping protect product integrity while also supporting salvage of high-value hardware where technically justified.

Skills Demonstrated

  • Product containment
  • MRB/NCR support
  • Customer approval coordination
  • Technical documentation
  • Risk-based quality decision making
  • Cross-functional problem solving

Case Study 6: Customer Visual Inspection Alignment

Project Type

Inspection Standardization | Training Support | Customer Requirement Alignment

Overview

Visual inspection expectations had become inconsistent due to legacy habits and over-inspection practices. Some parts were being judged to a higher cosmetic standard than required, which created unnecessary rework and confusion.

I helped drive alignment back to the actual customer visual inspection requirements.

Problem

Inspection and production teams were sometimes treating non-rejectable visual conditions as defects. This created unnecessary polishing, delayed flow, and made the acceptance criteria harder for operators and inspectors to apply consistently.

Actions Taken

  • Reviewed customer visual inspection requirements.
  • Helped distinguish rejectable conditions from acceptable/non-rejectable conditions.
  • Supported internal communication and training around the correct interpretation.
  • Created quality system actions to improve visibility and accountability.
  • Reinforced the importance of inspecting to requirements, not personal preference or legacy expectations.

Result

The project improved alignment between production, inspection, and customer requirements. It supported reduced over-processing and helped move the organization toward clearer, requirement-based decision making.

Skills Demonstrated

  • Visual inspection interpretation
  • Training and communication
  • Customer requirement alignment
  • Process correction
  • Quality system improvement
  • Practical manufacturing support

Project Type

Closing Reflection

These projects represent the type of work that motivates me to continue my education in Mechanical Engineering Technology. My professional experience has shown me that engineering and quality are deeply connected. A requirement on a drawing, a process step on a router, a customer specification, and an inspection decision all must work together as one system.

Through these case studies, I have developed stronger skills in technical analysis, communication, process improvement, and evidence-based decision making. My goal is to continue building the engineering foundation needed to solve manufacturing problems at a deeper level and contribute to safer, clearer, and more effective aerospace production systems.
