Chances are you’ve heard the buzzword, “Six Sigma,” but haven’t ventured deeper into what it means, and how it can support efficiencies in wholesale pharmaceutical distribution. Six Sigma is a data-driven methodology used to improve processes and eliminate defects or errors in various industries, including wholesale pharmaceutical distribution. While the principles of Six Sigma remain consistent across different fields, their application may vary based on the specific challenges and requirements of each industry. In wholesale pharmaceutical distribution, the Six Sigma principles are adapted to ensure the efficient and accurate delivery of pharmaceutical products while maintaining quality and compliance.

The Six Sigma principles in wholesale pharmaceutical distribution include:


Clearly identify and define the goals and objectives of the wholesale pharmaceutical distribution process. This involves understanding customer requirements, regulatory standards, and internal performance metrics. Defining the critical-to-quality (CTQ) parameters is crucial in this phase.


Accurately measure the current performance of the wholesale pharmaceutical distribution process. This involves collecting data on key process metrics, such as order accuracy, inventory levels, lead times, and delivery times. The data should be analyzed to identify areas of improvement and potential sources of defects.


In this phase, the data collected is analyzed to identify the root causes of defects or errors in the distribution process. Various tools and techniques, such as root cause analysis, process mapping, and Pareto analysis can be used to identify the most significant factors affecting distribution performance.


Based on the analysis, improvements are implemented to address the identified root causes. Solutions may include process changes, automation, training, or technology upgrades. The goal is to optimize the distribution process and minimize defects.


Once the improvements are implemented, the process needs to be monitored and controlled to sustain the gains. Key performance indicators (KPIs) are tracked to ensure that the process remains within the desired performance levels. Additionally, control mechanisms are put in place to detect and correct deviations promptly.


To ensure consistency and repeatability of the improved distribution process, standard operating procedures (SOPs) are established and documented. These SOPs become the basis for training employees and onboarding new staff members.

These principles are clear in their end goals, but what questions should you ask yourself when using Six Sigma principles to analyze and improve your wholesale pharmaceutical distribution policies and practices? Some examples of targeted questions to ask are:
