Objectives

With the massive amount of data being collected by the various sensors, there's definitely no way any GAStech employee can deal with the data to discover relationships or patterns without using any visualization tools. Hence, using all the visualization and analytical technique that I have learned in class, I aim to create an interactive data visualization to help GAStech management to be able to see patterns/identify anomalies/connections to better understand its operations in order to make better and informed decision.

With this interactive visualization, departments such as Security will be able to keep track of employee movements within the building to ensure that they are safe and also to prevent any unauthorized access to areas/zones that are prohibited. Furthermore, facility managers and executives could possibly identify areas that can improve the office environment such as to save costs and also to provide a conducive working environment for all GAStech employees.

Information Gathering

Looking at the given description of this challenge, there are some key information mentioned that are helpful and critical for my investigation.

• Staff members are required to wear proximity (prox) cards while in the building.
• The building is instrumented with passive prox card readers that cover individual building zones.
• Rosie – a free robotic mail delivery system is equipped with a mobile prox sensor, which identifies the prox cards in the areas she travels through.

Based on the given data, like any visualization processes, it is imperative and critical to understand and look through the data before using any visualization software. I will be using Tableau as my visualization software and there are some work to be done on the given datasets before I plot my visualizations.

Based on the information gathered above, the typical day for GAStech employees, in all departments:

1. Employees start entering into the building at 7am. By 9am, majority of the employees would have already reached their compartment/office.
2. Lunch break is usually in between 12pm to 2pm.
3. By 2pm, most of the employees will be back as observed by the large amount of movements/activities occurring during that period in all level of floors.
4. Employees typically ends work at around 5-6pm.
5. After 6pm, most of the departments would have left except employees from the Facilities,Engineering and IT department.
6. After 7pm, employees working in level 3, mainly executives, would have left the office.
7. At 12am, most of the employees would have left the building except for Facilities department who are on 24-hour rotational shift.
8. It is always the same people in facilities department that perform the night shift(Employee Stenig and Varja are found in Floor 1 as their offices are located in that floor).
9. Most GAStech employees do not work during the weekends. However, a few of the employees from the administration department came back during the weekends and work from 8am onwards till latest 3pm.
10. Some Employees from the Engineering & IT departments often stay till 11pm-12am.
