Question 1

From the visualization and analysis, we can safely conclude that Kasios International is not growing and is quite stable over the years, as the trend of calls, emails, purchases remain same. We can say that company has not expanded its resources over 2 and half years. But the company is getting more organized in terms of formal meetings as number of meetings shows increasing trend over the period of 2 years, specially after October 2015 which can be an indicator of changes in higher management for the organization or any other organizational structural changes.

Question 2

• Based on the analysis, we interpreted Richard Fox and Lindsy Henion are very prominent employees among the suspicious group.

• Among all other 20 suspicious employees, Richard Fox has the biggest network outside the suspicious group as well.

• List of the employees who are not in suspicious group but appeared to be closely associated with suspicious group members - Sachiko Sanabria, Garrett Sanfilippo, Lottie Grant, Palmer Kilborne, Michelina Lindorf, Bernard Harper, Laurice Eichenberg, Alexander Stevenson, Wilhelmina Nybo, Herman Todd, Jaunita Westen, Terrilyn Overkamp, Madeline Nindorf.

• Suspicious Purchases -
  • Employees involved in suspicious purchases are - Tobi Gatlin, Rosalia Larroque, Richard Fox, Meryl Pastuch, Jenice Savaria, Lizbeth Jindra, Gail Feindt
  • Other than suspicious employee provided by insider, only person involved in suspicious purchases is Gail Feindt who received most of the purchases. So, it is very much possible that he used to communicate with the suppliers to place the purchase orders.

Question 3

• We started our analysis with 23 "bad actors".

• From the network graph time line visualization, we observed how group composition and group's interaction change over 2 and half years of period.

• We observed, not only 20 suspicious actors detected by insider but other 3 employees Jaunita Westen, Terrilyn Overkamp and Madeline Nindorf were also part of the group's communication. It seems, Jaunita Westen and Terrilyn Overkamp initiated the communications in group, which can be termed as "suspicious communication".

• We noticed that number of meetings started increasing from Nov 2015 onward.

• Most of the communications were happening through Richard Fox and Meryl Pastuch.

• Suspicious activities were at the peak from Nov 2015 to April 2016 and then it reduced from May 2016 onward.
