Manning and a colleague, Dr. Erick Schmidt, a PhD sociologist and Executive Secretary to the Alberta cabinet in the 1960s, became interested in the General Systems Theory of biologist Ludwig von Bertalanffy and its possible application to governmental and business organizations. Together, Manning and Schmidt authored a "White Paper on Human Resources Development" for the Alberta government applying systems concepts to the reorganization of Alberta's social services. It was presented to the Alberta legislature in 1968 and later formed the basis of Alberta's Human Resources Development Authority and related programs under Premier Harry Strom, Ernest Manning's successor. Manning also contributed to the development of a "socio-economic development model" for TRW Systems of Redondo Beach, California, as the firm was endeavouring to shift its focus from the systems management of military projects to the management of "civil systems".
