The history of High Reliability Organizations (HROs) dates from 1986 when researchers identified similar characteristics found in organizations which appeared to operate error-free despite being very complex and operating under highly error-prone conditions. In 2001 Weick and Sutcliffe published what became a de facto set of five behavioral hallmarks, after which most publishing on the subject of HROs referenced those hallmarks, either individually or collectively, as objectives to be achieved to effect high reliability for an organization. Through the intervening years, HRO concepts have spread into use in multiple industries; however, there is little published on implementation, sustainment, or measurement tools that is widely cited in the literature. The objective of this research was to discover if there are practices of HRO implementation, sustainment, and measurement applicable to a wide variety of industries. The results show that there are some tools proposed for specific applications, but there is not a single toolset applicable to most industries. The results also show the healthcare sector along with the academic research sector to be most prolific industries for developing implementation and measurement strategies for HRO. Our analysis of the literature also supported the observation that the separate initiatives toward critical infrastructure protection not only closely parallel the fundamental objectives of the HRO but converge toward a more generalized construct.

Since the inception of High Reliability Theory in 1981, researchers and practitioners have theorized about the questions, “How do you know if you're an HRO, and how do you validate it?” Evidence now exists that organizations seeking high reliability and resilience have moved away from the theoretical phase, and into the application phase where organizations adopt the HRO hallmarks plus culture as operational targets and create interventions to effect change. The evidence of high reliability operations in organizations is key for validating that HRO is implementable and is also beneficial. After collecting over 1400 artifacts, we found 34 scholarly efforts published which purposefully targeted implementation measures toward achieving an HRO state and measured the outcomes. From that evidence, we concluded that three specific interventions have been used which were useful and generalizable to guide practitioners in moving toward an HRO state: process redesign, training, and organization redesign. We suggest that this evidence may assert that organizations which are not functioning as an HRO can be redesigned to do so.

The food distribution process is responsible for significant quality loss in perishable products. However, preserving quality is costly and consumes a tremendous amount of energy. To tackle the challenge of minimizing transportation costs and CO2 emissions while also maximizing product freshness, a novel multi-objective model is proposed. The model integrates a vehicle routing problem with temperature, shelf life, and energy consumption prediction models, thereby enhancing its accuracy. Non-dominated sorting genetic algorithm II is adapted to solve the proposed model for the set of Solomon test data. The conflicting nature of these objectives and the sensitivity of the model to shelf life and shipping container temperature settings are analyzed. The results show that optimizing freshness objective degrade the cost and the emission objectives, and the distribution of perishable foods are sensible to the shelf life of the perishable foods and temperature settings inside the container.

The term “high reliability organization” (HRO) evolved from research countering the claim by Perrow after the 1979 Three Mile Island nuclear plant incident that “accidents happen,” implying that failures were inevitable. Soon after the publication of Perrow's book researchers began questioning his assertion, by observing that some organizations exhibited significantly higher rates of reliability. In 2001, Weick and Sutcliffe converged on five principles, or hallmarks, which became the de facto characteristics most often cited since. Since 2001, HRO theory spread to non‐high‐risk industries and the amount of published literature has more than doubled, including several literature reviews. This led to the questions, “how has HRO theory evolved since the seminal research, how far has it spread from high risk industries, and what is the focus of HRO research?” Seeking to capture the breadth of spread of HRO as well as the dominant areas of research and practice, a comprehensive literature review was performed to capture the most current state of theory and practice. The results show HRO theory within the published literature has not significantly evolved past the original characteristics and hallmarks. Though the theoretical implications have not changed much the practical implications have grown and spread throughout the critical infrastructure sectors. In conclusion, the research team believes that a culture of reliability is the sixth hallmark that works synergistically with certain foundational organizational characteristics and allows mindfulness, which is the distinctive hallmark of HROs, to thrive and grow. This is the fundamental difference between “reliable” and “highly reliable” operations and differentiates HROs from well‐run organizations that are not HROs.
