Territory Assignment Tool

Sandoz Italia
Application that helps a pharmaceutical company keep track of sales reps territory assignments
In the world of pharmaceutical sales, the representatives of the company are each assigned to a territory inside which they carry out their activity. Given that the variables in this world are ever-changing (medics move away, reps resign, etc.) the company finds it hard to keep track and always have a clear image of what is going on with their sales force. The application extracts information from the client's information systems (via REST API) and updates the assignment of the reps to their respective territories. It is comprised of a back-end that provides the main functionality and a front-end that serves as a GUI and provides access to settings, logs, and statistics.

The application periodically accesses a web-based database to extract reports containing enrollment data for various company-owned websites. Due to the fact that there is no API access, this operation is performed via the front-end, with Selenium. The downloaded data is stored and then checked against the preexisting information, recorded in the company's Veeva instance, which is accessed via REST API. Because the enrollment data is filled in manually, the algorithm uses string matching techniques to overcome potential human error (typos, missing letters, special characters, etc.). The users that are already registered, are validated against a series of business rules provided by the client and divided by the system of provenience. The result is then output to files that are each sent to the person responsible for the respective system.

The application takes in structured datasets that have been filled in manually and performs deduplication of records based on one or more fields.
