Safety culture survey project outline

With the Aviation Safety Culture Inquiry Tool (ASC-IT), we provide a detailed insight into the safety culture of your organisation, revealing its strengths and weaknesses, and thereby providing opportunities for improvement. This tool has specifically been developed by the NLR Air Transport Safety Institute for use by all stakeholders in the aviation industry.

ASC-IT identifies improvement areas and indicates which barriers are impeding the effectiveness of safety management systems or other safety improvement programs. Also, by using ASC-IT, organisations have the possibility to benchmark their safety culture and to monitor safety improvements.

ASC-IT comprises 7 steps, which are executed by experts in the fields of safety culture and safety management:


A general explanation of each step is provided below.


ASC-IT always starts with a personal intake to fine-tune the process with you as customer. During the intake, we will discuss with you the purpose, background and approach of the safety culture assessment, as well as the best means to inform the target group about their participation. Obtaining support among participants is essential in reaching high response rates to the safety culture survey.
The intake comprises the following elements:

  • Purpose and desired output
  • Scope of the assessment
  • Timeline
  • Use of incentives and reminders
  • Use and frequency of progress reports
  • Means of reporting


ASC-IT is an online tool. When all e-mail addresses of the proposed target group have been delivered, we launch the safety culture survey on the agreed starting date. Participants receive a personal, attracting invitation by e-mail, tailored to your organisational culture. They only have to activate the link to access the online survey.


As soon as the safety culture survey has been launched, we monitor its progress. You receive regular progress reports, containing for example the actual response rate. If considered necessary, we adjust the survey approach to increase the response rate. This is done, for example, by sending reminders or offering additional incentives to participants. Of course this is done in consultation with you as customer.


After conclusion of the safety culture survey period, the raw data is processed, analysed and interpreted by experts in the fields of safety culture and safety management. This experienced team draws conclusions and makes recommendations relevant, tangible and workable for your organisation.


Based on the analysis, an ASC-IT investigation report is generated. The report comprises the following elements:

  • Background, origin, objectives, etc.
  • Approach
  • Results
  • Conclusions and recommendations

Wherever possible, the report is enriched with figures and tables to show the most important results at a single glance. Next to general impressions of the safety culture of your organisation, we offer attention to detail and specific results for each safety culture statement. This level of detail enables to develop targeted interventions. Our experts not only provide a report which explains the assessment results, but also provide tangible leads for your organisation to start improving the safety culture.


Completion of the ASC-IT approach takes the form of a personal presentation of the analysis to the customer. Especially the interaction with the customer enables to assess the results and make them more profound. In this session, the expert team will advise about follow-up steps and potential interventions.


In our experience, support from the expert team provide added value in the development and monitoring of follow-up steps and interventions. Assistance may be provided in various elements of the change management process all the way from establishing priorities and targets (depending on effectiveness, benefit, feasibility) based on the findings of the survey and interviews, to accomplishing the actual behaviour and performance changes. This is why we like to discuss with you what kind of support is requested to develop, plan and realise the follow-up steps as a result of the safety culture assessment.
