Engineers function optimally when using their specialized knowledge of the natural sciences together with the appropriate technology and associated hardware to address the challenges and needs of society. Engineering designs and the implementation of such designs are most often done in the format of a project or a portfolio of projects to ensure effective and efficient completion. To successfully implement such a project, it is essential that a skilled project manager should assume responsibility for planning, organizing, budgeting, scheduling, recruiting, directing, regulating, and closing it. It is clear that the success of any project may be greatly influenced by the competency and skills of this project manager. Over the years, engineers have often been tasked with, in addition to their engineering role, assuming the role of the project manager to implement or oversee the implementation of their designed solutions. With the everincreasing complexity of multidisciplinary , highly technology-based projects associated with the 4th Industrial Revolution, this dual role challenge has become even more daunting, especially when also having to carefully incorporate the environmental, social, labour, economic, and sustainability considerations. Unfortunately, it is true that many projects fail or come close to failure because of inadequately trained or incompetent project managers and their project teams. Inadequate communication, unclear objectives, improper planning, scope creep, not understanding the dynamics of the project, and financial mismanagement are often cited as some of the main reasons for project failure. Well-known examples of recent failed or close to failure high-profile projects include the yet to be completed, but already billions of US$ over-budget and years behind schedule, Kusile and Medupe power stations in South Africa (Moloi 2018), the environmental, catastrophically failed Deep-Horizon project in the Gulf of Mexico, and the controversial Millennium Dome project in the UK (Abbasi et al 2013). This paper investigates and discusses the specific skills, knowledge, and values that an engineer should possess, and then focuses on how these competencies should be developed for the engineer to also be an effective and successful project manager in today's complex, multidisciplinary world.
