Service delivery is seen as the act of providing citizens with basic amenities of electricity, water, housing, etc. by the government of any nation. However, this has been viewed to be capital intensive for some developing nations with high population and limited resources despite its necessity for economic growth and development. This article employs the Systematic Quantitative Assessment Technique (SQAT) propounded by Pickering and Byrne in 2014 to systematically review 50 articles published between 2013 and 2021 by 6 reputable data bases across 32 nations and 6 continents. The review itemized the themes adopted by various countries to overcome specific challenges to provide affordable and quality services to its citizens. Majority of the articles were empirical in nature while a few were conceptual. The highest number of published articles was found in Asian, African, and European continents while North America, Australia and South America had the least number of published articles. Survey, secondary data, and interviews were the highest methods of data collection while mixed and household level data were the least. It is advised that future research should be geared towards mixed data collection for effective comparison and validation of existing information (secondary data) that may have been used.
