Executive Summary

  • Sales, Admin and Operations departments in US and France contribute the most to interdepartmental dynamics

  • Recommended increase of contribution from support departments (Admin, Operations) located in Brazil and Germany

  • Recommended increased cooperation between well communicated US support departments (Admin, Operations) and poorly communicated support departments from Brazil and Germany in order to share best practices of how to provide more support for Sale department within their countries

  • Investigate reasons why employees working in some departments (e.g. UK IT, UK Operations, France Marketing) do not use online social network at all

Based on the information provided on inter-employee communication, the company has 664 employees and offices located in five countries:

  • Brazil (BRA)
  • France (FRA)
  • Germany (GER)
  • United Kingdom (UK)
  • United States (US)

As per company social network US branch employs the biggest number of people (277), whereas Brazil the smallest (66).

The company has six departments:

  • Sales (161 network users)
  • Admin (140)
  • Operations (134)
  • Engineering (100)
  • IT (77)
  • Marketing (52)

Considering employees located in different countries and working for different departments, company's corporate structure looks decentralized. All five offices have similar department structure with similar proportion of employees working for a particular department across different locations.

When a message is being sent within the organization, the most probable destination is United States followed by France and the least probable is Brazil. This phenomenon refers to each location from which massages are sent except UK, from where messages are mostly being sent either to Germany or to UK.

Surprisingly small fraction (3%) of messages sent from Brazil goes to Brazil
