In today’s knowledge-based advanced world, pioneer organisations emphasise more on knowledge orientation, being leaders in knowledge management (KM) implementation. The purpose of this paper is to identify the key factors influencing the successful implementation of each KM process in Iranian Oil and Gas Industry, specifically about operational projects which are classified based on the McKinsey 7S model as KM enablers, namely, strategy, structure, system, skill, style, staff and shared values. Then the paper assesses the KM maturity level to categorise and prioritise the KM enablers in each level. Moreover, a conceptual model is proposed to theorise the relationship between organisational agility and each KM process, namely, knowledge creation, storage, sharing and utilisation. Data analysis and statistical tests are concluded using structural equation model through the combination of confirmatory factor and path analysis. The results show the validity and fitness of the proposed model and verification of all the hypotheses, i.e. there are positive relationships between each KM process and agility.
