Exam E3 Topic 1 Question 244 Discussion

NNN is a logistics firm that contracts with online retailers (clients) to deliver parcels containing customers' purchases, to customers' home addresses. NNN holds inventory of the most frequently ordered products at its warehouses.
According to industry research, most clients require the contractors to deliver the customers their purchases soon after they place their order. They are not concerned with the environmental impact of the logistics process. They require very competitive delivery prices from their contractors.
Customer research reveals that households dislike being asked to stay at home for an entire day because logistics firms are unwilling to commit themselves to a precise delivery time. This problem has led to a small number of cases of customers arriving at the warehouses of logistics firms demanding to take their purchases away with them. Most households do not consider the environmental policies or performance of the firms they buy from.
The logistics industry is very competitive and NNN wants to protect its existing contracts and to win more. It needs to focus its resources on the 'things that must go right' in order for it to succeed.
Which THREE of the following are Critical Success Factors (CSFs) for NNN?
