Safety culture has been a topic of discussion in safety literature in the past three decades. Since its first mentioning after the Chernobyl accident much have been written about what fosters a positive safety culture within organizations. The Aviation Academy of the Amsterdam University of Applied Sciences conducted a literature review into safety culture development guidelines and identified a list of 37 prerequisites for safety culture development. Existing safety culture assessment tools target to measure the subjective perceptions of the workforce without examining the parameters affecting safety culture. Thus, they cannot be used to provide the organisations with guidance on the action points for improving their safety culture. To accommodate the need for practical guidance to companies, and as part of four-year research into Aviation Safety Metrics, the Aviation Academy has developed the AVAC-SCP tool, which aims to shed light on the planning and implementation for developing a safety culture. Knowledge experts and companies have reviewed the tool as a means to meet various criteria referred to literature with regards to safety metrics. The tool will enable organisations to derive actionable points from the results. A scoring method is included in the AVAC-SCP in order provide organizations with the ability to monitor their performance over time, compare between departments, and prioritize changes. The concept, academic background, reviews and other characteristics of the AVAC-SCP are discussed.
