Hello Wafa,
Thank you for your response to Samson’s post. I recall one of my former workplaces hiring a Lean consultant to address “muda”, or waste (Lean Enterprise Institute, n.d.). Many of the ideas presented in Lean seem beneficial, such as reducing the amount of time used and distance walked to gather medical supplies.
However, it was difficult to fully implement Lean, primarily due to another important aspect of health care, namely infection control. Many infection control items, such as gowns, masks, and gloves, must be thrown away after each use and could be considered waste. Further, other medical devices are complex and difficult to clean. These items are also considered “single use” and seem to be a waste.
The evidence for lean in healthcare is mixed. Some of the literature available states the gaps in evidence for improvement (DelliFraine, Langabeer, & Nembhard, 2010), while other papers note the lack of evidence supporting the notion of improvement from Lean (Moraros, Lemstra, & Nwankwo, 2016). Other authors note the complexity of health care improvement, comparing it to a “black box” (Ramaswamy et al., 2018). On the other hand, Lean (and its derivative Lean Six Sigma) may be beneficial to improving infection control, specifically healthcare-associated infections (Improta, Cesarelli, Montuori, Santillo, & Triassi, 2018). Lean also showed promise in surgical procedures (Mason, Nicolay, & Darzi, 2015).
I see Lean being part of the TSL’s toolbox. Lean helps the TSL understand current processes and possible waste in the system, thus increasing awareness. Awareness is one of the characteristics of a servant leader according to Spears (Northouse, 2013). Conceptualization is another characteristic of a TSL – Lean forces the TSL to take a big-picture view of system processes to creatively identify areas of improvement.
Thank you for sharing your overview of Lean. I look forward to adding Lean to my toolset!
