SMS has evolved over time from the technical era to the human factors era and then to the organizational era. Between the early 1900s and the 1960s, it was the technical era where aviation stood as a mode of mass transportation where safety failures were originally associated with technical and technological problems and failures. Therefore, much attention has been placed on the examination, inspection and improvement of technical factors. However, this was not enough as numerous accidents occurred. From figure 1 it can be seen that the aircraft was only repaired or repaired when parts were broken, this will definitely be unacceptable for today's industry. It could be potentially fatal and dangerous as a broken component of an aircraft can cause disastrous consequences and death. Moving into the human factors era, which ran from the early 1970s to the mid-1990s, there was a gradual decline in aviation accidents thanks to vast technological progress and improvements in safety standards. From Figure 2 it can be seen that after the 1960s aviation became a safer mode of transportation as there was a significant decrease in the accident rate. Therefore, human factors issues have been included in safety efforts. This created additional safety information research beyond that created during the previous incident investigation process. Despite having invested in resources to reduce errors, the human factor was still a persistent factor in accidents. The form of human factors depends on the individual and does not involve operational and organizational conditions. Until the beginning of the 1990s it was confirmed that if an individual works in a complex environment, various factors can lead him to behave differently. Human factors consist of ergonomics, circadian rhythm and individual characteristic factors. From the mid-1990s onwards we move towards an organizational era. Safety has been viewed with a systems approach, which means including organizational factors in technical and human factors. Therefore, the idea of ​​an organizational incident was created to include the significance of the organization's culture and behaviors on the effectiveness of safety risk controls. Furthermore, a new approach to safety has been introduced by collecting and examining previous accidents and incidents. This new approach requires organizations to be more proactive in identifying risks and hazards to prevent incidents from occurring. Therefore, the continuous approach to safety management has been formulated through proactive and reactive methodologies. Say no to plagiarism.

Achieving a strong SMS program alone is not enough, organizations need to cultivate a proper security culture to achieve a good SMS system. By definition, safety culture in the aviation industry is described as demonstrating responsibility for safety, how people work in terms of safety when there is no oversight. Having awareness of this, safety culture would mean commitment in achieving safety and SMS would mean competence in achieving safety. Having the commitment would be just one culture in contributing to the effectiveness of an SMS, few other cultures would be the safety behavior, fairness, access and attitude to information, awareness of the dangers and risks of SMS and l 'adaptability to changes and.
