Design for Six Sigma Masterclass

Lesson 1:  DMAIC AND DMADV

DMAIC and DMADV are two methodologies used in Six Sigma for process improvement and design. Here’s a breakdown of each: DMAIC DMAIC stands for Define, Measure, Analyze, Improve, and Control. It’s used to improve existing processes. Here’s a brief overview of each phase: Define: Identify the problem, project goals, and customer requirements. Measure: Collect data to establish a baseline for current performance. Analyze: Examine the data to identify root causes of defects or issues. Improve: Develop and implement solutions to address the root causes. Control: Implement controls to sustain the improvements and ensure consistent performance. DMADV DMADV stands for Define, Measure, Analyze, Design, and Verify. It’s used for designing new processes or products. Here’s a brief overview of each phase: Define: Establish the project goals and customer requirements. Measure: Identify critical-to-quality (CTQ) characteristics and measure risk and production capabilities. Analyze: Analyze data to develop design alternatives and select the best one. Design: Design and test the new process or product. Verify: Ensure the design meets customer needs and performs well under real or simulated conditions. Both methodologies aim to improve quality and efficiency but are applied in different contexts: DMAIC for improving existing processes and DMADV for creating new ones.

Lesson 2:  DMADV DEFINE AND ANALYZE PHASES

Here you will learn how to define the DMADV Define Phase, the measure, and analyze phases. This is where scoping, organising and planning the journey for your project occurs, where you understand the purpose, rationale and business case, as well as defining what resources you need to help you and how you will manage the project. The measure phase provides the framework around which the design can be built and is used to make design decisions needed in further phases The analysis phase is where the functional specification and high-level designs are developed, going on to create and test the detailed design, and you will grasp the balance of measures.

Free DMADV DESIGN AND VERIFY PHASES

Here you will learn an overview of using FEMA, and based on the outputs of the review, the high level design requirements can be finalised and a thorough risk assessment undertaken, and how the design phase starts by developing the ‘how’ thinking in more detail adding this to the various elements of the high-level design, with an emphasis on developing designs that will satisfy the CTQ requirements of the process outputs You will grasp the DMADV Verify Phase, where the design is piloted and assessed with the final step assessing the achievements made and lessons learned. You will understand how to choose between DMAIC and DMADV, and you will grasp an introduction to the quality function deployment (QFD) - also known as the House of Quality.

Free THE HOUSE OF QUALITY (QFD) Part ONE

Here you will learn that QFD Is a graphical representation of the logic flow, from identifying customer requirements to the detailed development of actions to ensure those requirements are met A series of seven interconnected matrices/room numbers are developed, moving from the requirements, through to design, implementation and deployment Customer Needs ROOM 1 Here you will identify and segment your customers, build a data collection plan, and conduct your customer research Competitive Information ROOM 2. Here you will determine which requirements are the most important so that when you enter the design phase you must understand the priorities from the customers viewpoint Characteristics and Measures ROOM 3 Here you will grasp the characteristics and measures needed to ensure the end design meets those requirements

Free THE HOUSE OF QUALITY (QFD) Part TWO

Here you will learn about relationships Room 4, competitive benchmarking Room 5, targets and limits Room 6, and Kano’s Model – evaluating requirements.

Free QFD AND THE PUGH MATRIX

Here you will learn about relationships Room 4, competitive benchmarking Room 5, targets and limits Room 6, and Kano’s Model – evaluating requirements. Correlation QFD and the Pugh Matrix. Room 7 the roof. The roof looks at the impact of each of the measures on the CTQ’s and how the measures affect each other This shows how the various characteristics and measures impact the end design – the objective is to resolve the conflict in situations before you build the design You will learn how to develop more houses of quality, QFD Drill-down The aim here is to develop further Houses of Quality slowly refining the level of detail until the design is specified at an implementable level You will grasp The Pugh Matrix (controlled convergence) is a framework for comparing solutions/concepts against a set of predetermined criteria
