Question1:
Is the methodology appropriate for the research objectives? What are the disadvantages of the sampling plan and the method of questionnaire administration?

Our answer:
 Not exactly. Since we conclude that the methodology can be divided into two steps (exploratory research& descriptive research), we would compare the advantages and disadvantages of the two steps as below. Advantages Disadvantages

Step1: exploratory research Sampling a group of restaurant employees. This step gets researchers familiar with the question and gathers information for further research. It needs expanding the methods. Researchers can do observation by disguising customers to get more real information.

Step 2: descriptive research Surveying a randomly selected group of restaurant customers using the questionnaire. It can thoroughly describe the market characteristics, derive the proportion of different customers and evaluate future customers' response by analysing the data collected. It needs expanding the sample range and size. Researchers may have depth interview with 5~10 customers to get more real, detailed description.
 Disadvantages of the sampling plan
1) The sample range is not representative.
It said the sample included randomly selected respondents on two different weekdays between the hours of 5 and 7 p.m. The customers selected at the time of "weekdays" and "hours of 5 and 7 p.m." cannot represent all the customers. They only investigated restaurant customers but ignore all the people of the community.
2) The sample size is too small.
Since the community has approximately 75,000 people, only 91 responses are received.
 Disadvantages of the method of questionnaire administration
It may ignore some details or information, and the validity cannot be promised.

Question2:
Review the questionnaire. What are its strong points? What areas or questions do you believe need improvement? Does it seem to capture the relevant information needed to meet research objectives?

Our answer:
 Strong points：
1) Avoid respondents’ inability and unwillingness to answer.
For example, question 5 demonstrates the first three objectives using the feeling interval scales
2) Question structure.
The questionnaire not only has unstructured questions but also has structured questions such as multiple- choice, scales.
3) Questions order
Qualifying questions at the front end of the questionnaire, easy questions next, main questions then, sensitive questions at the end.
 Improvement:
1) In question 1 and 2, the scale cannot cover everyone. It could be no more than once a month, 2-4 times a month, more than 5 times a month and First time at Juan Carlos’.
2) In question 10~16, the wording of sensitive questions seems a little bit annoying .It's better to illustrate before the questions that "To provide better service and experience to every customer ,we need the information as below .We promise we will never the confidence between us. "
3) Besides, questions asking about demographics seems too much. It's better to be reduced to around 2 questions or less.
 It seems to capture the relevant information needed to meet research objectives.
1) Question 5 asks about respondents’ attitude, which meet the 1st to 3rd objectives, question 7 make addition to the 2 nd objectives.
2) Question 1, 2, and 4 asks about respondents’ frequency and awareness, which accounts for the 4th objectives.
3) Question 3 and 6 ask about respondents’ towards competitors, which meet the 6 th objectives.
4) Question 8 and 9 ask about specific advice for improvement, which meet the 2 nd objective.
5) Question 10 to 16 evaluate demographic and geographic profiles of the customers according to area and customer demographics
