Purpose: The purpose of this paper is to study the effect of project management flexibility in early project phases on end-project performance including its mediating role on the effect of complexity over project performance. Design/methodology/approach: Out of 13 hypotheses, 6 hypotheses regarding the relationships between areas of flexibility and project performance, 1 regarding the effect of complexity on performance and 6 other hypotheses regarding the mediating effect of six areas of flexibility were formulated. Statistical analysis was performed using partial least squares–structural equation modeling on data gathered from 111 surveys. Findings: Research results revealed that flexibility of “how-attitude” and “how-organization” has positive significant effects on project performance. “How-attitude” contributes to the flexibility of project management processes by having an “open attitude,” “wide approach” and “proactive attitude” while “how-organization” put the emphasis of flexibility on “facilitate planning,” “outer organization” and “inner organization.” Moreover, this research confirmed that complexity has a negative effect on project performance. Among the six areas of flexibility, flexibility of “how-organization” mediates the effect of complexity on project performance. Originality/value: The increased project complexity requires some degree of flexibility in project management to deal with project dynamics. However, whether such flexibility in early project phases has an effect on end-project performance has not been empirically investigated. This research contributes to filling the gap in literature about the relationship between project management flexibility and project performance. Such effect was investigated by studying the direct effect of flexibility on project performance and the mediating role of flexibility on the negative effect of project complexity on project performance.
