Proposed the 'open access' business model in 1970s.
In June 1970, Isabel Benham distinguished herself yet again by becoming the first rail analyst to propose the "open access" business model, a concept that would later be extremely influential across various sectors, including railroads, telecommunications, pipelines, and utilities. Inspired by the need for increased competition and efficiency, this concept challenged the traditional operational structures, promoting a more open and competitive landscape. The idea of 'open access' would eventually revolutionize industries by encouraging competitive service offerings within a shared infrastructure, illustrating Benham’s foresight and innovative mindset. Her suggestion had lasting impacts, notably influencing policies and operations well beyond the railroad industry.
