* [[Malcolm Gladwell]] discusses the Dunbar number in his popular 2000 book ''[[The Tipping Point]]''. Gladwell describes the company [[W. L. Gore and Associates]], now known for the [[Gore-Tex]] brand. By [[trial and error]], the leadership in the company discovered that if more than 150 employees were working together in one building, different social problems could occur. The company started building company buildings with a limit of 150 employees and only 150 parking spaces. When the parking spaces were filled, the company would build another 150-employee building. Sometimes these buildings would be placed only short distances apart. The company is also known for the [[open allocation]] company structure.
