How can you deliver exactly what your customers want? By implementing the customer-focused philosophy of Six Sigma, you can learn how to cut costs, increase revenue and maintain a competitive advantage by utilizing a customer-centric approach throughout business processes.
Six Sigma encompasses a set of methodologies focused on eliminating errors and improving operations to improve products or services and achieve customer satisfaction. Two of these tools are DMAIC and DMADV. While both are similar in that they focus on efficiency and effectiveness, the methodologies are used in different circumstances.
DMAIC vs. DMADV: The Five Phases
DMAIC is best utilized when project managers and stakeholders want to improve an existing business process.
- Define the problem with your process or product
- Measure your current process and collect data
- Analyze your data to clarify your goals
- Improve your process based on your data and goals
- Control your new process and monitor for continued success
DMADV is associated with creating a new product or design.
- Define the process, parameters and design goals
- Measure and identify several aspects of your process or product, including production capabilities and risks
- Analyze and test the product or service to create a baseline for improvement
- Design and optimize your process details by conducting tests and comparing results
- Verify the chosen design for your process and implement and monitor the new process
DMAIC vs. DMADV: How Are They Similar?
During the first three phases, both methodologies focus heavily on information and fact-finding by collecting and analyzing data and other metrics. This stage of both methodologies will help drive the rest of the process by providing information to create a baseline for improvement. Ultimately, both DMAIC and DMADV will help set performance standards that can be utilized to streamline resources and achieve business goals.
DMAIC vs. DMADV: How Are They Different?
The most notable differences between the two methodologies are in the last two steps of each process. DMAIC focuses on making changes to an existing business process to eliminate or reduce defects. DMADV concentrates on designing a new product or process to match customer needs.
During measurement phases, DMAIC measures the current performance of a process as compared to DMADV, which uses customer data (including specifications and needs) as primary metrics.
DMAIC vs. DMADV: When Should They Be Used?
DMAIC is generally used to improve an existing product or process that is no longer meeting customer needs and expectations. Project managers and other professionals can utilize this methodology to fully understand why customers no longer need this product or service and how to evolve what your organization is creating.
DMADV is best used for developing new products, services and designs while keeping customer requirements in mind during every phase of the process. For example, during the “Define” stage, project leaders should use customer feedback to identify customer wants and needs. During the “Define” stage of DMAIC, it could be as simple as identifying the current processes that should be examined before moving onto the next phase.
Ultimately, both well-known Six Sigma methodologies provide a framework for project leaders and professionals to make business process improvements and make a positive impact on your organization.
