Another popular method of design is the IDOV model. This method is similar to other Six Sigma approved methods of continuous improvement and product design. The IDOV model stands for Identify, Design, Optimize, and Validate.
The IDOV model within the Six Sigma Methodology stands for Identify, Design, Optimize, and Validate. Most closely, this method reflects the PDSA cycle, followed by the DMADV and DMAIC cycles. Most often the IDOV model is used in manufacturing plants rather than in service industries.
The Identify phase comes first in this model. This is where a customer need is identified. A team is established to listen to the customer and convert their needs and expectations into product specifications. Technical expectations are identified and figured into the plan. Then the plan is put into writing with the roles and responsibilities of each team member and the milestones are clearly defined. This includes detailed timelines, graphs, and other visual tools to help keep the project on target.
During the Design phase, the product’s design is laid out. This includes formulating a concept, identifying potential risks associated with either the project, and a plan is created to either avoid potential risks or to deal with them as they arise. A plan is developed to procure raw materials and for the manufacturing process.
The Optimize phase first assesses the process to ensure that all the critical design parameters are being met. Then the process is designed for performance, reliability, and is error-proofed as well. Cost analysis is done to avoid excess spending, especially for the start up costs, which can quickly go over budget if not constantly monitored.
The final phase is to Validate. This is where the design and processes are tested, analyzed, and changed as necessary. Prototypes are validated as well for how close they come to meeting the customer’s needs and expectations, along with their performance and their DPMO rating; remember that in Six Sigma the aim is always a level six or 3.4 defects per million. If the design is flawed, improvements are made now, as are changes to the process.
