Whole-of-government approach (WGA) is a strategy that encourages government institutions to work together, rather than in isolation, to tackle complex problems and achieve shared goals and citizens’ expectations in respect of service delivery, among other outcomes.
It also seeks to introduce coherence in the decision-making process of public administrations. The first reference to this operational approach, then referred to as joined-up-government, is found in Tony Blair’s administration in the United Kingdom.
