Question 1 :Using the four large Kasios International data sets, combine the different sources to create a single picture of the company. Characterize changes in the company over time. According to the company’s communications and purchase habits, is the company growing?
Growing pattern Interpretation:
In terms of Meeting, Purchase, Call, Email record from May 2015 to December 2017, four graphs below indicate the trend of the number of records separately.
From Purchase, Call and Email record perspectives, starting in May 2015, the number of records increased rapidly in the next two months (July 2017). After this, the number of records of the three aspects almost keep dynamically stable trends.
From the meeting records, the number has kept a growth trend since October 2015. Before this, the number of meeting almost is 0.
Conclusion:
In a sum, the company grows rapidly from May 2015 to July 2015. After this, in general, the company keeps a dynamically stable trend in the communications and purchase records.
Question 2 :Combine the four data sources for group that the insider has identified as being suspicious and locate the group in the larger dataset. Determine if anyone else appears to be closely associated with this group. Highlight which employees are making suspicious purchases, according to the insider’s data.
Suspicious staffs interpretation:
After filtering out the all excels given by the competition, the two figures below indicate what I have found. For the source figure, it indicates the 26 people are the event organizer involved in the suspicious activities including Call, Email, Meeting, and Purchase. Clearly, the figure RichardFox is the most active staff involving the suspicious events and the sum number of all events is 65. Similarly, the other figure, the employee making suspicious events, indicates the suspicious staffs. It turns out GaiFeindt and KerstinBelveal are the two staff who deserves the highest effort to observe.
