Project portfolio risk management. Bibliometry and collaboration Scientometric domain analysis

Purpose‘'Project Portfolio Risk Management” is approached through a bibliometry and collaboration networks study determining its dynamics development as formal domain that links Project, Management concepts.Design/methodology/approachTo facilitate replicability, scientometric under PRISMA structure carried out: i) Identification or structuring, well keywording accuracy; ii) Screening: Search string refinement outputs review; iii) Eligibility: Several criteria applied to content analysis, iv) Inclusion: Consolidation of analytics networks.Originality findingsAssessing the field knowledge novel, contributing synthesis trends evolution: For first time, descriptive statistics show increasing attention based on growing citation scores, participation, H index productivity main journals. Project Selection established hot topic, authors are identified, key concepts such optimization, mathematical programming, multi-objective stochastic robust optimization. Three research themes obtained: Incorporation Assessment into problem, process, Analysis considering social environmental issues. An accurate match found in contrast domain's behavior with some bibliometric linguistic laws.Practical implicationsTheoretical richness achieved conjunction three terms, presenting tendencies thus focus related processes unified for use both scholars' practitioners’ perspectives.
