A number of dramatic changes were enacted during the first decade of this century resulting in the improved quality, uniformity, and efficiency of accident analysis procedures. Additionally, many investigator qualification regulations have been reformed. In particular:
Traditional practices of accident investigation and safety management systems in multimodal industries, such as aviation and marine, are now being integrated to create uniformity of reporting and eliminate less effective practices.
Demands for law reform and upgrades to high-risk industrial and transportation sectors have resulted in new codes that require more professional investigations to achieve a higher uniform standard of analysis and reporting.
New analytical technologies have enabled conclusions to be made to a higher degree of certainty than ever before. However, recent economic pressures have required investigations to achieve this level of quality while being more cost-effective.
