“The equipment does not fail,” said Gimenes. “And the improvements in flow mean our lead times have become shorter, so the GC lab supports the company’s cash flow due to inventory cycle time reduction that consequently enhances business sustainability.”

Pharmaceutical lean lab principles are centered around creating more value with fewer resources by optimizing workflows and eliminating waste.

Lean philosophies were first introduced in the ‘90s in manufacturing, evolving from Toyota’s implementation of lean strategies. In lab environments, lean laboratories are managed and organized to drive process optimization. Lean labs are focused on delivering consistently efficient outcomes — both in terms of speed and cost-effectiveness — while maintaining a relentless focus on quality.

Implementing lean lab strategies starts with value stream mapping.

Value Stream Mapping

Value stream mapping helps to visualize the entire workflow of a laboratory. By mapping out each step, you can identify bottlenecks and non-value-adding activities.

In GSK's case, reorganizing workbenches into miniature production stations categorized by value stream gave lab workers a more logical and efficient workflow, reducing unnecessary movement and accelerating throughput.

5S Methodology

The 5S methodology can be applied across industries but is particularly effective in labs. Implementing 5S in a pharmaceutical lab can produce dramatic improvements in efficiency and quality.

5S stands for:

  • Sort: Eliminate unnecessary items and movement from the workspace
  • Set in Order: Organize remaining items for efficiency
  • Shine: Inspect and clean lab work areas
  • Standardize: Create standard operating procedures
  • Sustain: Maintain the new order

The way GSK used METTLER TOLEDO workstations and equipment is a solid example of the "Set in Order" principle in action.

Continuous Flow and Pull Systems

Lean labs enable a continuous flow of work for peak efficiency. This is often achieved through the implementation of pull systems, where downstream processes "pull" samples from upstream processes as needed. Resources are provided as needed, rather than having materials "pushed" through the system regardless of the downstream capacity.

It can be a subtle but effective change to improve efficiency and eliminate waste.

Visual Management

Visual management tools, such as Kanban boards or digital dashboards, can enhance communication and workflow in a lean lab. These tools provide information about the status of various processes, helping to identify bottlenecks and manage workloads more effectively.

As optimization occurs, these dashboards help to identify non-value-added activities that can be further eliminated to streamline processes. They also provide you with a way to monitor and assess any changes you make.

Standardization

Standardizing procedures wherever possible is key to a lean environment because standard practices produce consistency and repeatability. It also makes it easier to train new staff and identify areas for improvement.
