Purpose
This study aims to assess the relationships among tacit knowledge sharing, communities of practice (CoPs) and employees’ abilities to solve problems, customer’s satisfaction and innovation.

Design/methodology/approach
This quantitative research aims to examine the causal relationships among the key study variables. A questionnaire-based survey was developed to evaluate the research model by drawing a convenience sample that includes 219 employees working in the King Abdullah Design and Development Bureau which is located in Amman, Jordan. Surveyed information was examined following the structural equation modelling procedures.

Findings
Results revealed that sharing tacit knowledge in defence organizations had no direct effect on employees’ abilities to solve problems, customer’s satisfaction and innovation, while there was an affirmative effect to CoPs on employees’ abilities in those areas. Also, this study showed that CoPs had a significant mediating role to play in the relationship between sharing knowledge and employees’ abilities in terms of solving work problems, customer’s satisfaction and innovation.

Research limitations/implications
Findings of this study have laid the basis for future studies related to examining the effect of tacit knowledge sharing and the CoPs on improving employees’ abilities as preconditions for organization performance. These findings can be supported by conducting further research studies to examine the large samples of defence companies to give deeper meanings and insights to the relationship among the key study variables. The authors recommend expanding future studies and examine the mediating role of other social learning methods such as mentoring and storytelling on the relationship between sharing tacit knowledge and employees’ abilities.

Practical implications
The research model may enable managers and practitioners to make decisions related to the improvement of collective learning by encouraging employees’ engagement in the process of tacit knowledge sharing. The model also helps managers to understand the role of CoPs as a knowledge sharing tool that contributes to increasing employees’ abilities and organizational competitiveness. Furthermore, the research model can be a step forward for further research studies on the relationships among tacit knowledge sharing, CoPs and employees’ abilities.

Social implications
The suggested model can act as the promising step for continuous improvement to the defence industry in terms of producing high-quality products and services that protect national security, humans’ lives and society at large from enemies and terrorist groups.

Originality/value
In spite of the fact that most academic studies on knowledge management show a positive relationship between tacit knowledge sharing and organizational performance, a few studies have examined the effect of mediating the CoPs on relationships between sharing tacit knowledge and employees’ abilities as preconditions for raising the performance of the organizations working in security and defence industry. Hence, this research attempts to fill these gaps and gives a new direction for future research.
