According to Black (2011), Six Sigma is used to evaluate the capability of a process to perform defect-free, where a defect is defined as anything that results in customer dissatisfaction.
Here’s the Six Sigma concept that 3DR leadership can use to implement change within their organization while staying focused on future growth.

As outlined above, 3DR can start with the Define stage. During the Define stage, 3DR can identify the problem associated with their operational system(s) that may be causing profit loss and/or product efficiency challenges. Next, 3DR can focus on the metrics and measurements associated with the actual operational system problem(s) they identified. Following this will be 3DR’s opportunity to Analyze the data they identified/collected on the operational system(s) problem(s). Once they analyze the data collected on systems, 3DR can then move to the Improve stage where their employees can identify potential solutions. Lastly, 3DR can take massive action and implement solutions for the problems they identified. All-in-all, 3DR can management the quality control process thru good leadership and constantly modify processes associated with product/service inefficiencies.
