However, this is the most expensive way, which is stressed in the case given. It could allow the restaurant to be flexible in data collection and obtain responses from a considerable number of clients. Moreover, there is an opportunity to get in-depth answers, given that the customers will be able to provide information where and when they feel comfortable. At this point, a critical aspect should be emphasized – Santa Fe Grill is to realize the extent of the importance of the survey. If the data is essential indeed, then the approach of developing a particular software is rational as the related costs would be justified.
In contrast, if this survey is more like a supportive undertaking, it would be better for the restaurant to consider the option of handling paper questionnaires. In this vein, the variant with asking the clients to complete these questionnaires at their table either before or after they get food. Such an approach will not impose any pressure on a customer and allow him or her to take time and give responses promptly. The other suggested options would rather disturb or interrupt the clients from doing their activities.
In order to get an extended amount of data, it may be reasonable to collect it from customers of competitive restaurants. One possible way to do it is to provide them with paper questionnaires after they leave these restaurants. Questions here should be closed so that a person would not spend much time on responses. Then, these customers may be identified online from the competitors’ social media followers and be provided by the survey via various platforms.
