Background
Every two years, SUM libraries conduct a comprehensive survey to receive feedback from the faculty, students, and staff with regards to the libraries' services. With the data collected, SMU libraries hope to gain some insights so that they can enhance their existing services and meet the emerging needs of SMU faculty, students and staff.
However, the past reports were not able to give a comprehensive and condensed summary for SMU libraries as they are mainly made-up of pages of tables. With so much information, it becomes difficult for SMU libraries to get an essential overview that allows SMU libraries to gain useful insights.
Objectives
With such a massive amount of data being collected, it is important to summarize the key areas and provide proper visualizations for them. Hence, using all the visualization and analytical techniques that I have learned in class, I aim to create an interactive data visualization to help SMU libraries better understand their service feedbacks so that they can make improvements on their services to satisfy the needs of their respective users.
With this interactive visualization, SMU libraries would be able to easily gain insights from the feedback given by the following stakeholders:
- undergraduate students
- postgraduate students
- faculty
- staff
Data preparation and Dashboards
With the given data(2018 Survey dataset), like any visualization process, it is vital to understand and look through the data before using any visualization software. I will be using Tableau as my visualization software and there is some work to be done on the given datasets before I plot my visualizations. The given data consist of two main files: One contains the tabular data while the other contains feedback comments. To create a concise and comprehensive visualization that highlights the most important feedback information to SMU libraries, I would only be using the tabular data.
For the tabular data, there are many fields, but can be separated into 'identifier questions' and 'ranking questions'.
'Identifier questions' are mainly categorical questions that are used to categorize the respondents. The questions include:
- StudyArea - Area of study/research/teaching
- Position - Years of study/Occupation
- ID - local or international student
- HowOftenL - Frequency to library
- HowOftenC - Frequency to the school campus
- HowOftenW - Frequency to accessing library resources
'Ranking questions' are the main feedback from respondents. Data is collected are mostly on the Likert scale (from 1-lowest to 7-Highest). Most of these questions are repeated three times for different purposes: Importance(I), Performance(P) & NA. For I and NA, they both have the same 26 questions while P has one extra question, "Overall how satisfied are you with the Library?".

Home Dashboard
The following shows the home dashboard:
Importance ranking
The following shows the importance dashboard:
Level of services perceived by undergraduate, postgraduate, faculty and staff (Importance)
Performance ranking
The following shows the Performance dashboard:
Level of services perceived by undergraduate, postgraduate, faculty and staff (Performance)
Now that we have created all the necessary dashboard, we are ready to use it as a platform to conduct our exploration and analysis.
