Özet (Çeviri)
Railways are complex systems and not easy to manage and control. With the developing technologies, it is almost inevitable to make changes on railways and these changes may bring risks with themselves. So it is crucial to do necessary assessment before implementation of a change. Also in order to provide safety in organisations, information about the changes should convey to the people who will take over the responsibility. It is common to see deadly accidents on the news and some of them might have been prevented thanks to proper configuration management (CM). In this project, there are two case studies which are accidents. So in order to understand how accidents happened two popular accident causation models were reviewed with their criticisms in the literature review. One of them is Reason's model which is based on“Swiss cheese”model and second one is Leveson's model which is based on constraints. These models help to see relation between causes and effects (Qureshi, 2008). Also definition of CM and criticism of the yellow book (RSSB, 2007) were mentioned in the literature review chapter. The aim of this project is to seek answer for the question (can better configuration management prevent accidents?). One of the case study in this project is the Santiago train derailment which resulted with 79 people were killed and around 140 people were injured. The author was advised by Mr Felix Schmid that before the Santiago accident happened there were probably some deficiencies in CM in the organisation. Therefore it was chosen for a case study in this project. The other case study is London Underground Limited (LUL) open door incident which happened due to confusion of the driver. Fortunately, no one was hurt during the incident and the train was taken out of service after the incident. It can be seen from the incident report that one of the main causes of the incident was the sensitive edge system override modification. It is also mentioned on the report that LUL had not done necessary risk assessment before implementation of the change. Proper CM required to do necessary risk assessment and to be sure that the change is necessary and results of it acceptable. So it was thought that the LUL incident would also have been prevented thanks to proper CM. In order to review whether the organisations did proper CM, a checklist was generated by using the document -ISO 10007:2003 Quality management systems-. The checklist consisted of two parts; organisational and change parts. Then by using data from internet and official documents, the probable causes of the incident and accident were listed. Also Reason's and Leveson's accident causation modes were simply applied to the case studies. After that the checklists were filled by drawing upon on the information and the data, and then the deficiencies in CM were found. The deficiencies were mentioned with their explanations in this project. The deficiencies were matched with the probable causes of the accidents. It showed that some of the main causes of the cases are related to the deficiencies. It was concluded that if proper CM had been done before the accidents, the deficiencies would not have existed, so some of the main causes of the cases would have been resolved thanks to proper CM. So if proper CM had been done, the accidents would have been prevented. It can be concluded that proper CM may prevent some future accidents and so why not every organisation does not do proper CM. However doing proper CM may require extra budged and extra stuff. Its requirements may be difficult to comply with for some organisation, so organisations should review CM option before doing it and they should do proper CM. Otherwise it may not help to prevent accidents and it may just be extra budged for the organisations. Investing money on safety prevents potential accidents and accidents mean losses for organisations. Therefore investing money on CM does not mean dead investment, it rather means saving money and reputation. Organisations think that they are enough safe otherwise they would take precautions. So they cannot easily foresee potential accidents ant do not put precautions to prevent future accidents. However proper CM helps to see risks on organisations and prevent organisations from bad decisions. Accidents harm organisations in terms of losses, bad impression, and damage cost. It means if potential accidents are prevented, organisations will not lose money and their popularity above all they may save lives. The author thinks that safety is important and importance of the safety should be comprehended by the every people in organisations because those people maintain safety in organisation. Systems and constraints enforce people to provide safety without participation of people, safety may not properly is provided. CM may prevent some critical accidents but even CM is implemented by people, so training of the people is highly important for providing safety.
