Robert Halligan

FIE Aust CPEng IntPE(Aus) - Managing Director, Consultant & Course Presenter

Mr. Robert Halligan is an executive professional engineer, manager and engineering practitioner, renowned internationally for his role in the practice and improvement of technology-based projects. He is highly sought after as a consultant for his considered expertise.

Mr. Halligan obtained his qualifications in communications engineering at the Royal Melbourne Institute of Technology (now RMIT University). After early engineering, engineering management and project management roles with Telecom Australia, Department of Defence (Australia), Rockwell International and Andrew Corporation, Mr. Halligan has over the last twenty-five years contributed to major systems projects worldwide.

Mr. Halligan has worked extensively in Australia, the United States and the United Kingdom. In recent years, Mr. Halligan has consulted and trained on engineering processes for companies whose goals have been to successfully commercialize their technologies.

The passion Mr. Halligan brings to systems engineering, and how to translate it into enterprise improvement, has benefited countless organizations worldwide: private, government and academic. Mr. Halligan has gained experience in almost every definable business sector, over a broad spectrum of technologies. He has performed engineering, engineering management and project management roles in private enterprise, including large transnational corporations and in the intelligence area of the public sector.

Products and systems developed by Mr. Halligan over many years have achieved commercial success in the United States and in Australia, and remain in use today. Application areas in which Mr. Halligan has significant experience are communications, medical products, aviation, consumer products, energy, land transportation, space and defense.

Over his career Robert has personally developed systems engineering-related artifacts that further advance the state of systems engineering. These include the Wedge Model (a derivative of the traditional V Model). He has also personally developed:

  • a novel, efficient and very effective method for dealing with states and modes
  • a very efficient and effective requirements capture and validation methodology
  • a methodology for measuring requirements quality
  • a leading trade study methodology
  • a very sound, practical functional analysis methodology.

In addition to the above, he has also developed sets of advanced data item descriptions (DIDs) for key systems engineering documents, including System Requirements Specification, Software Requirements Specification, Interface Requirements Specification, Verification Requirements Specification, Interface Design Description, Architectural Design Description, Concept of Operations (CONOPS) and Systems Engineering Plan.

These DIDs, reflecting as they do improved practices vis-à-vis those of the best public domain DIDs (the DI-IPSC-8xxxx series), are in widespread use in PPI’s client base of hundreds of companies worldwide.



Mr. Halligan has led numerous systems engineering efforts, on projects of up to $1 billion.  As a hands-on engineering manager, he is expert in the strengths and weaknesses of a wide range of relevant systems engineering-related standards. He has consulted extensively in the area of requirements quality and its relationship to project risk, and on many other aspects of systems engineering.

Clients served by Mr. Halligan for PPI include Aerosystems International (United Kingdom), BAE Systems (United Kingdom), Boston Scientific Corporation (USA), Raytheon (USA), Medela (USA), Ximedica (USA), GDLS (USA, Canada), Sciex (Canada), Mitsubishi (Japan), Tellabs, Inc. (USA), Kongsberg Defence Systems (Norway), GE Medical Systems (USA), Cochlear (Australia, Belgium), Alcatel (Belgium), EADS (Germany), Thales (the Netherlands, Australia), Gentex (USA), Department of Defence (Australia), Airservices Australia (Australia), NATS (UK), Nokia (Poland), HAVELSAN (Turkey), and many others.

Mr. Halligan is a Past President of the Systems Engineering Society of Australia. He was an Australian delegate to the ISO WG7 developing the international system life cycle processes standard, ISO/IEC 15288, and for three years led the delegation of the International Council on Systems Engineering (INCOSE) to ISO/IEC JTC1 SC7 on software and systems engineering. Mr. Halligan was a key reviewer of EIA 632 (Engineering of Systems) and EIA 731 (Systems Engineering Capability Model). He co-chaired the launch in Nashville, TN of the latter standard. He was a contributor of content to EIA/IS 632 and its successor in the area of requirements quality, and to IEEE 1220 in the area of functional analysis. He was a member of the team that developed ISO/IEC 15288, and has been a reviewer of all subsequent editions of this standard.

Robert has had the following relationships with universities, thereby contributing to the undergraduate and postgraduate education of engineers worldwide:

  • development and delivery of the Master’s module “Managing Engineering Projects” for the University of Sydney/University of Technology Sydney. This module comprised one sixth of the courseware for the Master’s degree.
  • guest lecturer for the National Defence University, Finland
  • guest lecturer for the Singapore Institute of Technology
  • delivery of a one-week Winter Workshop in SE for 3rdyear students in Mechanical Engineering at the University of Stellenbosch, South Africa
  • several one-week deliveries to Masters and PhD students at the Graduate School of Design and Management, Keio University, Japan
  • lecturer designate for the Transnet Centre for Systems Engineering, Wits University, South Africa
  • guest lecturer for ITA, Brazil
  • presenter for Draper Laboratory at Massachusetts Institute of Technology (MIT), on several occasions including a very recent contribution.

Mr. Halligan has also served as Director (International) of INCOSE, and for several years was an INCOSE Ambassador. He is an Honorary Member of the Korean Council on Systems Engineering and of INCOSE Brasil, and was heavily involved in the formation of these chapters.
