The Client’s Journey
Every technical academic project begins with understanding the client’s challenge, the assessment expectations, and the practical work required to create a complete submission.
Amitava Bhattacharyya approached Excellence Innovations for assistance with the submission of a Six Sigma Black Belt assignment. The first conversation established that the work would require more than conventional academic writing: the supplied case data had to be interpreted, analysed statistically in Minitab, and organised into a defensible DMAIC improvement project.

The Initial Enquiry
After the initial discussion and a short voice call, the client shared the case materials. These included the Excel dataset “LSS Case 27.xlsx” and the supporting case document “LSS Case 27.pdf”. From this point, the project was developed as one integrated technical-and-academic workflow rather than as separate pieces of analysis and writing.
The first conversation shows the client requesting support for a Six Sigma Black Belt assignment, followed by agreement to review the guidelines and discuss the project in more detail.
Understanding the Client’s Requirements
The assignment concerned XYZ Manufacturing Ltd., a training-football manufacturer operating a multi-stage production process involving material selection, panel cutting, stitching, bladder insertion, assembly, inspection, and quality control.
The core quality problem was product durability. The project materials repeatedly identify an average football lifespan of approximately 300 days against a desired requirement of 360 days. The gap was associated with recurring failures, replacement costs, customer dissatisfaction, and pressure on profitability and competitiveness.
The process was not simply producing a small number of unusual failures. The supplied analysis indicates that lifespan measurements were tightly clustered around a mean that was consistently below the required standard. This suggested a systematic performance problem: the manufacturing process appeared relatively stable, but stable at the wrong level.
Average football lifespan around 300 days versus a required 360 days.
Quality concerns concentrated in assembly, bladder insertion, panel finishing, valve fit, labelling, and final inspection.
Higher replacement and quality-related costs associated with inadequate durability.
Growing customer complaints and competitive pressure requiring process improvement.
Need to improve product quality while reducing defects and maintaining long-term control.
The Main Business Challenge
Case Data and Project Files
Following the initial discussion, the client shared the source Excel dataset and the eight-page LSS case document. This gave the team the information needed to review the problem before beginning the Six Sigma and Minitab work.
Our Approach
Step 1: Structuring the Work Around DMAIC
The project was organised around the five connected stages of Six Sigma DMAIC: Define, Measure, Analyze, Improve, and Control. This created a clear relationship between the business problem, the statistical analysis, the proposed solutions, and the long-term control strategy.
Project workflow
Initial Enquiry → Requirement Review → Case & Dataset Assessment → DEFINE → MEASURE → ANALYZE → IMPROVE → CONTROL → Minitab Interpretation → Academic Write-up → Draft Sharing → Client Review → Final Delivery
Step 2: DEFINE – Establishing the Problem and Scope
The Define phase established why the durability problem mattered, what parts of the manufacturing process were included, and what improvement outcome was expected. The business case linked poor product lifespan to replacement costs, customer dissatisfaction, and profitability. The project scope covered material selection, panel assembly, bladder insertion, manufacturing operations, and quality control, while external supply-chain factors were kept outside the defined scope.
Problem statement aligned with business objectives.
Voice of the Customer (VOC) and Critical-to-Quality factors (CTQs) linked with customer needs.
Process flow organised through SIPOC/process mapping.
Goal: increase average football lifespan to at least 360 days while reducing defects.
Step 3: MEASURE – Defining the Variables
The Measure phase converted the quality problem into measurable variables. Operational definitions were established so that the analysis would be based on consistent criteria rather than subjective interpretation.

Progress Updates and First-Draft Follow-Up
Keeping the Client Involved Throughout the Project
Client communication remained important throughout the assignment. Amitava did not simply submit the brief and wait for the final delivery. The communication record shows follow-up messages, requests for progress updates, and concern about the timing of the first draft because his institute was actively following up.
At one point, the client wrote that he had “full faith” in the team but requested to be kept updated. A subsequent message noted that the institute was following up for the first draft. These exchanges show why communication and milestone visibility were important parts of the service.
Draft Development and Minitab File Sharing
The clearest technical evidence appears during the draft-sharing stage. The communication explains that the written work had been developed up to Slide 14 in the PPT template, while the remaining analysis outputs and interpretation still needed to be incorporated.
Three files were then shared with the client: “Amitav.docx”, “Minitab.mpx”, and “DEFINE.docx”. The presence of the Minitab project file directly connects the statistical software work with the academic project, while the DEFINE document demonstrates the structured use of the DMAIC methodology.

Client Confirms the Review
After the completed project, the client was invited to leave feedback. He first requested some time and then returned the following day to confirm that the review had been completed.
Client Review
Amitava Bhattacharyya
“Big shoutout to Biplab and Kusal for all the help. These guys are super knowledgeable and don’t just give you generic advice—they actually take the time to understand what you need and walk you through it. If you’re looking for someone who is easy to talk to and really knows their stuff, they are the best. Definitely worth reaching out to.”
Published Five-Star Client Review
The published review reinforces the same themes visible throughout the project communication: knowledgeable support, a willingness to understand the client’s specific requirements, personalised guidance rather than generic advice, and communication that the client found easy and useful.
