Lean Six Sigma for hospitals and the pharmaceutical sector

How does Lean Six Sigma fit in with GMP requirements in the pharmaceutical industry? The core principles of Lean are universal: eliminate waste, create flow, add value for the customer. However, its application differs significantly between the healthcare sector and industry. In industry, the output is physical and measurable. Standardisation is the norm and deviations can be quantified. In healthcare, the patient is the customer — with emotional, medical and personal needs that differ from person to person. Standardisation must be balanced against the variability of care needs. Furthermore, healthcare professionals are trained to act autonomously, which makes change more challenging. Perfact’s approach in healthcare: a patient-centred perspective, co-creation with healthcare professionals rather than top-down implementation, extra attention to psychological safety, and coaching by our Human Development specialists to achieve sustainable behavioural change.

The pharmaceutical industry operates under strict GMP (Good Manufacturing Practice) regulations set by the FDA and EMA. Lean Six Sigma is not only compatible with these regulations — it enhances compliance. Six Sigma reduces variation in production processes, which directly contributes to GMP-compliant quality assurance and fewer out-of-specification (OOS) results. Lean eliminates unnecessary actions and simplifies processes, making documentation clearer and audits more manageable. In concrete terms: lower OOS rates due to more stable processes, more efficient batch release via optimised quality control procedures, lower costs of quality defects (COPQ), and higher OEE of production facilities. Perfact has Black Belt-certified consultants with combined experience in GMP environments and the process industry.

Hospitals are, in essence, also logistics organisations — with sterile materials, medicines, instruments and equipment that need to be in the right place at the right time. Inefficient stock management and internal logistics lead to nurses spending time searching for items, stock going out of date, unnecessary orders and — in the worst-case scenario — delays to operations. Lean Six Sigma offers proven methods to improve this structurally. Specifically, we apply the following approach: Stock management: using an ABC analysis, we identify which materials are critical and which can be safely reduced. A two-bin system (kanban) replaces manual counting and ordering — materials are automatically replenished as soon as the first bin is empty. Result: less time spent searching, fewer expired products and lower procurement costs. Internal logistics and OR planning: using Value Stream Mapping of the entire surgical preparation process, we identify where time is lost — from sterilisation to the instrument trolley in the operating theatre. Through standardisation of instrument sets, improved planning in the sterilisation department and clearer handover protocols, the turnaround time between operations can be demonstrably reduced. Increasing operational throughput: less time spent searching for materials, fewer last-minute replenishments and shorter preparation times directly lead to greater operational capacity within the same budget — without the need for additional staff.
