NASA's safety culture - Part One: Assessment
This three-part article series will outline the steps NASA took to address its culture and safety climate: assessment, intervention, and initiatives currently unfolding in the rest of the agency.
The current situationWe first needed to understand the current culture and climate at NASA in order to recommend focus areas for improvement.
By culture we mean the shared values and beliefs of an organization â€” commonly described as â€œthe way we do things here.â€
By climate we mean the prevailing influences on a particular area of functioning (such as safety) at a particular time.
This assessment was accomplished through a review of previous work, a survey of NASA employees, and a program of interviews.
A specially modified version of the web-based BST Safety Climate and Culture Survey was administered to all NASA employees in all 11 NASA locations. This yielded an overall response rate of 45.2 percent, a comparable result from previous NASA culture surveys. The BST Safety Climate and Culture Survey measures the underlying determinants of organizational culture and safety climate. These factors include:
1 â€” Procedural Justice
2 â€” Leader Member Exchange
3 â€” Management Credibility
4 â€” Perceived Organizational Support
5 â€” Workgroup Relations
6 â€” Teamwork
7 â€” Safety Climate
8 â€” Upward Communication, and
9 â€” Approaching Others.
The survey was supplemented with additional NASA-specific questions. Agency-wide response to the basic survey scales is shown in Figure 1. The percentiles in this figure reflect a comparison of NASA results with a normed database.
Reviewing resultsAt an agency-wide level, NASA scored well in relation to other organizations in the database on most of the scales comprising the survey.
Two scales where NASA scored lowest were Perceived Organizational Support (POS) and Upward Communication (UC). POS measures perceptions about the organizationâ€™s concern for the needs and interests of employees. Individualsâ€™ perceptions of organizational concern for them influence beliefs about the organizationâ€™s values for safety, which in turn affects employeesâ€™ willingness to raise safety concerns. UC measures perceptions about the quality and quantity of upward communication about safety concerns.
Lower scores on Perceived Organizational Support and Upward Communication indicated areas for particular focus during the culture change effort. Senior management, and the behaviors that they stimulate through the management chain, influence both of these factors. These factors are also strongly influential on the culture in ways that relate directly to mission safety.
Interview findingsTo help provide context for the survey results, interviews were conducted with more than 120 people at NASA headquarters, the Glenn Research Center, and the Johnson Space Center. At each location individual interviews were conducted with members of the senior management, and group interviews were conducted with representative groups of individual contributors, as well as supervisors and managers.
Interviews disclosed a strong sense of dedication and commitment to the agencyâ€™s work; however, we also found frustrations. During the interview program we received a number of indications that there were impediments to speaking up at NASA. This was consistent with the Upward Communication survey result, and indicated that there were non-managers within NASA who felt that open communication was impeded.
An organization in transitionThe NASA culture described in the assessment reflected a long legacy of a can-do approach to task achievement â€” but did not yet fully reflect the agencyâ€™s stated values of Safety, the NASA Family, Excellence, and Integrity. The assessment reflected an organization in transition, with many ongoing initiatives and lack of a clear sense at working levels of â€œhow it all fits together.â€
In sum, we identified an opportunity to strengthen the cultureâ€™s integrity by helping NASA become an organization that lives its values. In the next installment of this series we'll discuss how these findings were used to tailor an initial implementation at three of NASAâ€™s centers, as well as the commencement of senior-level coaching at NASAâ€™s headquarters.
