Orientation: Innovation is forged by sub-revolutions as described by the quadruple helix (QH) model.Research purpose: Innovation model formation is complex, and the useful QH model can develop and improve to be exemplary.Motivation for the study: The rationale of the study is to validate and improve the QH model Boys hoodie with additional concepts, fresh perspectives of experts and the investigation of the primary sub-revolutions forging innovation.Research design, approach and method: A conceptual and critical review approach implied narrative data of the model from secondary sources; a convenience sample of five innovation experts for critical reviews was thematically analysed.Main findings: Ultimately, the improved QH model must accommodate the legal, moral and ethical world to merge with the physical, biological and digital worlds; appropriate terminology for QH innovation leadership is needed, and triple technology theory (TTT) should be incorporated with the triple management theory (TMT) dimension of the model; the review conformed the sub-revolutions of ALKALINE STICK innovation with respect to (1) innovation leadership, upscaling agility and innovation essentials, (2) the triple helix (TH) ecosystems sub-revolution and epochal society and (3) the new technological paradigm, technology intensity and TMT.
Practical/managerial implications: The already useful QH model is confirmed and may develop to become exemplary with respect to the hypothetical improvements suggested.Contribution/value-add: A fresh and improved QH model is suggested in the context of complex innovation model formation and the paucity of literature.
