The 5 principles of the lean lab

In the fast-paced world of pharmaceutical development, labs are under increasing pressure to deliver more, faster, and at a lower cost—all while maintaining high-quality standards. 90% of QC teams could achieve significant productivity gains by implementing lean lab strategies with the goal of optimizing laboratory processes, reducing waste, and improving efficiency and service levels.

This guide explores the five key principles of the lean lab and highlights the potential benefits and challenges of implementing these strategies.

In this guide, you’ll discover:

Principle 1: Levelling your workload

One of the primary sources of inefficiency in labs is volatile incoming workloads. Labs often face peaks and dips in demand, making it difficult to maintain a steady workflow. To manage this, many labs over-resource to handle peak periods, leading to inefficiencies during quieter times. The key to improving productivity is workload levelling, which involves spreading work more evenly over time.

This can be achieved through techniques such as queuing, which prioritizes tasks based on urgency and lead time, allowing labs to optimize resource utilization and prevent analyst burnout. This permits labs to plan resources closer to the levelled demand rate and optimize utilization rates, while safeguarding quality and service levels.

However, maintaining a levelled workload in practice requires continuous adaptation to changing conditions.

Principle 2: Implementing flow

Flow refers to the uninterrupted progress of work from start to finish. In the lab context, this means minimizing work-in-progress and ensuring that tasks are completed without delays because, when tasks are interrupted, errors are more likely and it becomes harder to maintain quality. Two models help implement flow in the lab:

1. The rhythm wheel
   • used for predictable, repetitive tasks like environmental monitoring.
2. The train system
   • used for handling more volatile, unpredictable workloads.

The question to ask is: why should you test samples now when you can wait and test them in a campaign with other samples tomorrow and still deliver everything on time? By grouping similar tasks and waiting to test samples in batches, labs can improve efficiency without compromising deadlines.

Principle 3: Define standard work

Standard work helps identify variances in the work, make improvements, and reduce re-tests and unplanned work.

It involves documenting the optimal processes and procedures for performing lab tasks. By defining standard work, labs can identify variances, reduce re-tests, and minimize unplanned work. Standardizing work processes also helps to onboard new analysts more quickly and reduces downtime when analysts are unsure of their next steps.

You can think of standard work as acting something like a GPS: it guides lab workers along the most efficient path for completing their tasks.

Principle 4: Short interval control vs visual management

In a busy lab, it’s essential to have a clear overview of what’s happening at any given moment. A team with clear and organized information-sharing can juggle all tasks successfully, and visual management is critical to ensuring everyone knows what’s going on.

Visual management techniques include:

• Scheduling whiteboards
• Daily stand-up meetings
• “Walk the queue” meetings

These methods help lab teams stay organized and on track, ensuring that all team members are aware of priorities, task progress, and any potential issues. By making information visible and easily accessible, labs can respond to challenges more quickly and maintain productivity.

Principle 5: The lean lab paradox

While lean lab strategies focus on eliminating waste, there is a paradox: saving time does not automatically translate into productivity gains if the lab lacks effective workload levelling and flow, meaning that the processes require ongoing monitoring and adaptation.

Because these strategies depend heavily on counter-intuitive theory, it’s common for lean principles to fade from view once the lean implementation specialists move on to other projects. Hence, such initiatives often struggle to sustain their impact over time, especially when driven by external consultants.

Thus, to ensure that lean principles endure, it is critical for labs to integrate the full range of strategies into their daily operations. In the modern, connected laboratory, this makes it all-the-more important for organizations to embrace digital tools that allow them to continuously adapt and evolve.

Becoming digitally lean

Sustaining lean lab practices over the long term requires more than just initial implementation; it requires digitalization. Digital tools help labs maintain lean principles by automating processes, adapting to changes in real time, and ensuring that best practices are consistently followed.

A digital lean lab can optimize resource utilization, manage variability, and maintain high service levels without the need for constant manual adjustments. This allows labs to fully ingrain lean principles, constantly adapt to context, and ensure that lean practices stay at the heart of their operations.

Conclusion

Lean lab strategies can significantly improve lab performance by optimizing workflows, reducing waste, and improving service levels. However, sustaining these gains requires continuous adaptation and the use of digital tools to maintain lean principles over time. By embracing digitalization, labs can ensure that lean practices become an integral part of their operations, leading to lasting productivity improvements and better outcomes for their customers.
