Therefore, the possibilities of stock-outs occurrence increases when inaccurate data is manually collected. In conformity, a study conducted by Kang & Gershwin (2004, p. 19) reached the same conclusion, as its findings recognized human errors a chief contributor to stock-outs and shrinkage events, through user involvement in product identification and manual counts.
Moreover, Kang & Gershwin (2004, p. 4) justified, false labelling can lead to stocks being stored in wrong aisles, which will consume time and create diffculty in finding them later. If the lost-stocks were not soon found, they will be considered stock-outs. Another possible reason can be ineffective delivery planning carried out by suppliers’ employees, as this can result in lacking inventory at the customer’s warehouse when needed (Tourtoulo, Laurent, & Mace, 2006, p. 21).

Likewise, Mpwanya (2005), had also utilized primary quantitative data from questionnaires, face-to-face interviews and phone interviews to introduce a theory; nevertheless, phone interviews were time consuming and improper, due to the long list of the questions to be asked. On the contrary, Mandala & Gunasekaran (2002) did not justify the primary techniques used to support their statements in their case study; as it is was dependent on secondary resources
