The Lean Laboratory
Leaning the Quality Control Laboratory
Lean principles can work in any laboratory environment, including pharmaceutical, medical, and chemical manufacturing laboratories. This article shows how, through some exemplary applications in pharmaceutical QC labs.
​
Pharmaceutical manufacturers continue to operate in an increasingly competitive environment, contending with issues that run the gamut from lost revenue as patents have expired, ballooning costs for new drug research and development, changes required by new regulations, and global market pressures to reduce costs and improve quality and delivery.
​
The quality control (QC) laboratory plays a critical role in pharmaceutical production, for both in-process and finished product testing. Labs not only monitor and control the quality of incoming APIs (active pharmaceutical ingredients), and other supplies used in the manufacturing process; they are also instrumental in the batch release process.
​
As a result, steady pressure is on to improve operations in pharmaceutical QC labs. In general, the challenge boils down to this: finding a way to improve capacity and utilization of resources, reduce lead times while increasing reliability, and speed up the authorizations necessary for both production and batch release.
​
Lean thinking provides useful ways to address the challenge. However, while lean has been used extensively in many discrete and process manufacturing industries, laboratories have lagged behind in applying lean principles. But they are starting to catch up. This article covers some ways they are doing just that.
The QC Laboratory Environment
Like many service operations, lab processes are mostly intangible, and take place in a black box.
​
QC laboratories play a crucial role in the manufacturing value stream for pharmaceutical products. But lab environments have their own special characteristics. In fact, labs share many aspects of both manufacturing and service operations, in a unique combination.
​
Labs are like super-clean manufacturing environments, where significant attention must be paid to both safety and compliance. Equipment is often highly sophisticated, extremely sensitive, and very expensive, and proper operations and maintenance are essential to avoiding equipment breakdowns.
Labs are internal suppliers to the pharmaceutical manufacturing process, but like many service operations, their processes and «products»—timely test results—are mostly intangible and invisible in comparison with those of manufactured goods. Processes often take place in a «black box.»
Maximizing both staff time and machine time is essential in the lab, as is standardizing work to ensure that protocols are followed. In reality, though, it’s all too familiar to find laboratory technicians and managers continually grappling with:
​
-
Variable demand and uneven workloads
-
Complex scheduling that combines routine testing with special tests and projects
-
Individuals who are their own mini-silos; that is, they are set up to work to their own schedule or «drumbeat» rather than to the rhythm of demand
-
Large backlogs and missed deadlines, which trigger fast-tracking or expediting of work and further complicate scheduling
-
Plenty of conformance, but not much real control
What’s lacking is two-part:
​
-
The top-down, managed work of standardizing processes, of analyzing the nature of demand and how it matches with resources, and of finding a better way to effectively manage flow and scheduling; and …
-
The bottom-up, self-managing processes of visual management and lab organization, skills development, and teamwork.
The Impetus the Need for Speed
Everyone was used to working with the long lead times associated with in vivo testing...
​
To illustrate how a specific strategic change can serve as the springboard for a lean transformation, let’s consider the case of one international pharmaceutical company we’ll call Fine Pharma.
The impetus for launching a «lean lab» at Fine Pharma began with a change from in vivo to in vitro testing on a key (and very expensive) product line. In addition to the social and ethical benefits associated with reduced animal testing, in vitro testing would also be much faster, and much less expensive after the amortization of new testing equipment.
According to Catherine Converset, president of Productivity Europe and senior consultant with Productivity Inc., the change brought a big challenge:
« Everyone was used to working with the long lead times associated with in vivo testing, »
Catherine Converset said: « the impact on the whole lab was significant, as everyone had to get used to the shorter lead time and learn to work differently. »
​
Establishing a lean laboratory environment would help reduce lead time and stabilize the QC process so that the company could effectively use a quicker batch release process.
