“…However, when considering operational audits, prior literature has identified various difficulties in its effective practice. These can be attributed to the difficulties in determining audit scope and associated audit output due to the unclear and ambiguous nature of the 3Es (Everett, 2003); lack of a clear and consistent methodology to undertake operational audits (Reichborn‐Kjennerud & Johnsen, 2011); difficulty in gathering sufficient and reliable evidence (Lapsley & Pong, 2000); time, expertise and funding constraints (Al‐Twaijry et al, 2003; Kells, 2010; Kells & Hodge, 2009), the need for an independent, experienced and well‐structured audit committee (Everett, 2003; Goodwin‐Stewart & Kent, 2006); and the lack of adequate management support for the function and its recommendations (Funnell & Wade, 2012; Lapsley & Pong, 2000).…”
