August 8, 2025Aug 8 Hello everyone, I recently interviewed for a Process Excellence Manager role. After clearing the first round, I was given a case study and asked to solve the problem using the Six Sigma methodology. I prepared and submitted my presentation, but the recruiter’s feedback was that I had not done what was asked. I’d like to share the case study details and my submitted work here to get your input: What could be improved in my approach? Were there any gaps in applying the Six Sigma methodology correctly? Any suggestions for structuring the response more effectively for future opportunities? I’d greatly appreciate your honest feedback so I can improve my problem-solving approach for such assignments. Thank you in advance Driving_PEX.pptx Process Excellence Case Study.pdf
November 17, 2025Nov 17 1. Alignment With the Case Study Requirements Gap: The response did not use the DMAIC framework or any structured methodology (Define–Measure–Analyze–Improve–Control). It appears more like a consulting proposal than a method-driven Process Excellence solution. 2. Completeness and Depth of Solution A. Vendor PR to PO Automation – Gaps No root-cause analysis of existing PR/PO delays, data issues, or vendor compliance problems. No acknowledgement of process variation across warehouses, which the case explicitly highlights. No mapping of the current workflow to identify failure points. B. GRN Process Reengineering – Gaps Does not account for differences across warehouses and dark stores. No plan for SOP rollout, change management, or training. No reference to typical GRN error types (mismatch, damages, lost-in-transit) or bottleneck analysis. C. Route Optimization & Delivery Planning – Gaps No analysis of existing routing failures. Key constraints not considered (vehicle capacity, SLAs, cut-off times, replenishment patterns). No linkage to inventory movement or demand variability. D. Process Digitization & Control Tower – Gaps No clarity on control tower architecture (layers, data flows, integration boundaries). No discussion of governance, alert mechanisms, or exception-handling. 3. Use of Key Tools & Methodologies The case clearly called for Lean/Six Sigma (DMAIC), SOP design, ERP/SCM customization, and dashboarding. Assessment: The response did not demonstrate DMAIC or structured problem-solving. Impact: This reduces methodological rigor and makes the response appear like a high-level consulting pitch rather than a Process Excellence case solution. 4. Expected Success Metrics What the candidate included: PR–PO cycle time reduction GRN accuracy improvement Routing cost reduction OTD improvement Fewer vendor disputes Gaps: No baseline values vs. targets. No justification for chosen metrics. Several numbers seem generic or overly optimistic (e.g., 99.5% GRN accuracy). No ROI or cost–benefit assessment. 5. Structure, Communication & Professionalism Strengths: Clean, professional deck. Good logical flow (Challenges → Approach → Pillars → Roadmap → Metrics). Easy to read visually. Gaps: Looks like a generic consulting proposal, not a case-specific analysis. No process maps, “as-is vs. to-be” comparison, or data-driven diagnosis. Too high-level for a Process Excellence role. 6. Comparison Against Real Interview Expectations A strong candidate would typically: ✔ Conduct root-cause analysis (Value Stream Map, SIPOC, CTQs) ✔ Apply DMAIC clearly ✔ Address warehouse-level variations ✔ Break down PR–PO, GRN, and routing workflows ✔ Provide a location-wise transformation approach ✔ Highlight risks, dependencies, and change management The submitted response is polished but generic, lacking the analytical depth expected from an Operations Excellence professional.
