## McKinsey & Company US, 2019 .f3[ 🇺🇸 Organized into five regional centers or 'complexes': Northeast, Mid-Atlantic, South, Midwest, West Coast ] .f3[ 🇺🇸 Organization had grown into this shape from the early days of the company. Common wisdom was that it made sense. ] .f3[ 🇺🇸 Question raised: *What drives collaboration between our people?*] .f3[ 🇺🇸 Answer: Other things are more important than physical location. ] .f3[ 🇺🇸 Consequence: Abolition of regional structure, integration into a single United States practice. ] --- class: left, middle ## Analytic method 1. Created metrics of connection between 1,000+ sampled consultants 2. Created a network graph based on these measures 3. Used a community detection algorithm (the Leiden algorithm) to break the graph into distinct communities of more densely interacting groups. 4. Analyzed groups by key descriptive demographics to see how they were best described. 5. Used visualization methods to demonstrate conclusions in the most compelling way --- class: left, middle ## The original graph <img src="plain_graph.png" width="1165" height="400" style="display: block; margin: auto;" /> --- class: left, middle ## Graph by location <img src="graph_loc.png" width="1165" height="400" style="display: block; margin: auto;" /> --- class: left, middle ## Graph by Leiden community <img src="graph_comm.png" width="1165" height="400" style="display: block; margin: auto;" /> --- class: left, middle ## Community characteristics <img src="overlap_heatmap.png" width="1165" height="400" style="display: block; margin: auto;" /> --- class: left, middle ## Assortativity and Modularity Assortativity is a mathematical measure of how likely two vertices are to be connected based on a shared characteristic. Modularity is a measure of the accuracy of a community structure. |Characteristic | Assortativity| Modularity| |:----------------|-------------:|----------:| |Location | 0.07| 0.13| |Industry | 0.23| 0.37| |Leiden Community | 0.29| 0.45| --- class: left, middle ## Compellingly illustrating community <img src="leiden1.gif" style="display: block; margin: auto;" />
