“…Considering that an antecedent cannot simultaneously be an antecedent and a defining attribute for the same concept (Walker and Avant, 2014: 173), the antecedents identified from the selected material are those events that may explain the nature and the dimensions of the concept and phenomenon to which it refers. The analysis of the selected texts revealed that the following categories of antecedents are associated with the concept ‘challenge’ within the context of this study: - the diversity of legitimate expectations of the population or citizens of a country for the performance of public functions (Hellevik, 2012: 572);
- the diversity of individual, societal, political, judicial, administrative, multinational, regional and national role players (Christensen et al, 2015: 359);
- orientations, such as ethical principles, ethos and values (Larat and Chauvigné, 2017: 2–3);
- the conflicting or overlapping nature of political authority, constitutions, legislation, mandates, delegations and directives authorising PA functions (Hellevik, 2012: 654, 572; Tibane and Lentsoane, 2016: vi, ix, 7, 64);
- diverse international and/or country-specific priorities, strategies, requirements and expectations with regard to PA functions (Constantin et al, 2018: 19; Hellevik, 2012: 557, 568); and
- performance agreements, service targets and standards for PA functions (Brusca and Martínez, 2016: 1; Hansen, 2014: 32).
