    • 8D Problem SolvingDiscussion - While DMAIC is a more popular approach as compared to 8D Problem Solving, would you prefer to use 8D over DMAIC in some situations? Why/ Why not?
    • Design FMEA and Process FMEADiscussion - What are the key differences between PFMEA and DFMEA? How does Design FMEA feed in to Process FMEA? What kind of feedback is expected from Process FMEA to Design FMEA?
    • Lean - Discussion - What Is Lean?
    • Six Sigma DMAICDiscussion - What is Six Sigma, DMAIC Methodology?
    • Combining Six Sigma and LeanDiscussion - Lean and Six Sigma are two different approaches for process excellence, where Lean focuses on efficiency and Six Sigma focuses on effectiveness. In the more recent times, Lean and Six Sigma have been combined to form Lean Six Sigma. What are some of the advantages and disadvantages of combining the two approaches? 
    • Design for Assembly Discussion - Explain the meaning and application of DFA index for a component.
    • Design Risk Analysis Discussion - What are the common tools for Design Risk Analysis? 
    • Design of Experiments Discussion - What are the key differences in OFAT (One Factor at A Time) testing and DOE (Design of Experiments)? What are the advantages of one over the other?
    • Unusual Observation - Discussion - A statistically unusual observation or an outlier is of special interest many a times. However, an outlier is ignored or removed from data set sometimes. What are the factors that help one decide if an outlier is to be considered and investigated or if it can be ignored safely?

    • DMAIC vs DMADV - Discussion - How is DMA of DMAIC different from DMA of DMADV ?
    • Tollgate Effectiveness - Discussion - The quality of questions and interactions in Toll Gate reviews is crucial for success of any gated process (not just Lean Six Sigma projects). It is seen that poorly planed or administered Toll Gate reviews are one of the biggest reasons for project failure in the Lean Six Sigma world. How should one plan toll gate reviews to ensure their effectiveness? 
    • DMAIC vs KaizenDiscussion - Explain by giving examples how should one decide about selecting a suitable process improvement approach in a given situation. Compare and contrast DMAIC with Rapid Improvement sequences like Kaizen.
    • Drum Buffer Rope ApproachDiscussion - Explain Drum, Buffer and Rope approach and describe how it relates to Kanban.
    • Activity Based CostingDiscussion - Activity-based costing (ABC) is a way of accounting which identifies and assigns costs to overhead activities. These costs are in turn assigned to products. Cite examples where using such a way of accounting has clear advantages and cite examples where using this method creates complications.
    • Mistake Proofing Discussion - While it is understood that mistake proofing is immensely effective, there is some confusion about what it means or intends to achieve.
    • RPA (Robotic Process Automation) Discussion -  What is the difference between Artificial intelligence (AI) and Robotic Process Automation (RPA). Can the highest level of automation be achieved without the two working in tandem?
    • Five Focusing Steps of Theory Of Contraints - Discussion -  What are the five focusing steps of Theory of Contraints? Provide an example. 
    • Kanban Board - Discussion Kanban Board was initiated as a Physical Board for teams who have a standing meeting every day to allocate tasks, report progress and take decisions. It has evolved in different ways in different domains. Provide examples for different kinds of Kanban Boards.
    • EfficiencyDiscussion - What are some examples of most common efficiency metrics that are used in the business world? Which one's may be considered better than the others?
    • Why DMAIC is not sponsored by some leaders? - Discussion While most leaders seem to agree that DMAIC is a logical sequence, needs top management support, can be used flexibly and makes business sense, what are some of the Leadership reasons for not supporting this methodology wholeheartedly (in many companies)?
    • Failure of 80:20 RuleDiscussion - How do you tackle a situation (as commonly found in IT Infrastructure) where you find that large volumes of IT Tickets points to different isolated root causes most of the time? Do you think that fixing issues quickly as they occur is the best way to handle such a situation? What other similar situations have you faced?
