Langfun Tech is hiring an office manager.  In their interview, they talk about doing the searching type tasks. Out of the tools: Tableau, Excel, a CRM, AntConc, MaxQDA, and Weka, which would you recommend and why?

1. They want to create a map of the US, showing the geographic locations/concentrations of their customers.

The tool Tableau would be best suited for this task, as it has the ability to graph geographic locations and to make interactive dashboards with the given data. 

2. Langfun wants to keep track of all the people that have called them and whether or not they become customers.

In order to achieve this it would be best to use CRM, as it is specifically designed to log and track customer and client interactions over time. 

3. Langfun wants to track how many contracts they have issues over the past year and months, and which of them where for what category of servcie.

The most efficient tool for this task would be Excel, as it is able to measure entered data over time easily, and is very easy to manipulate and edit.

4. Langfun has focus group data from potential customers and they want to analyze it to look for customer preferences.
