Acero et al. (2019) employ a case study in their research to evaluate value system analysis application in military logistic operations where response time, cost-effectiveness, variety of material references, and demand uncertainty are decisive elements of combat agility and capability. The study structure employs the research DMAIC (definemeasureanalyzeimprovecontrol) method whose principles align with lean kaizen operations. The article relies on Six Sigma in lean methodologies applied to improve manufacturing and business processes operations by minimalizing variability by focusing on defects in operations and their causes. The results obtained are presented using value stream design (VSD) and value stream mapping (VSM) tools to improve the order processing lead time. While the study effectively discusses the implementation of value systems in a supply chain, the use of advanced language on the subject limits the accessibility of the material for readers who first encounter the concepts.

Andreadis et al. (2017) investigate how value stream management practices are implemented. The research methodology investigates the lean philosophy and the correlations present with some of its tools. Three research questions and five hypotheses are formulated and tested using Pearson correlation, descriptive statistics, One-way ANOVA, 2-Sample proportion, Tukey-Pairwise comparison tests, and 1-Sample t-tests. The authors introduce the concept of soft aspects in lean logistics essential in implementing value stream practices. The data was collected using questionnaires issued to 168 manufactures from across the globe. The researchers then develop a conceptual framework that guides the implementation of Value Stream Mapping (VSM) predicated on the study results. The article structure is accessible for readers and applies the study result in creating a conceptual framework for implementation of VSM that introduces learners to strategies...

The article employs a discursive approach to help the readers, who are assumed to be interested in the implementation of VSM in their enterprise, the concepts of VSM. Gellad and Day (2016) illustrate how VSM can be implemented in a gerontological clinic and suggest practical steps to practice daily operation. The article evaluates how VSM has been implemented in the health care sector to improve the value of care according to the patients perspective. The authors suggest steps that a gerontological practice can employ to implement lean operations. Further, the study discusses the material and information flow mapping to ensure the concept is understood and suggests the nature of the teams that should be involved.

Hoffmann et al. (2018) posit that the inefficiency in the clinic-level delivery of HIV care services inhibits engagement in care. Maintaining engagement for HIV patients is essential for the success of global HIV treatment and prevention. The attrition along the healthcare continuum from testing positive, beginning antiretroviral therapy (ART) to achieving an undetectable viral load has been associated with a high prevalence of HIV in South Africa in the past. The study examines the lead time (time spent waiting for that service) and the costs incurred during 15 visits in South Africa. The study asserts that a patient-centered approach to care would decrease the burden of care, which is aligned with the suggestions made by Gellad & Day (2016). The use of the South African context effectively illustrates how efficacy can be realized to ensure the integrity of the HIV global programs due to the logistic challenges in the countrys healthcare.
