OIS was created by INSIGHT implementing the author’s proposal to integrate two very successful modeling techniques: one from operations (supply chain network design) and the second from sales and marketing (marketing mix modeling).  The two firms  that created OIS are:

• Optilogic: From its website: “Supply chain design software innovator Optilogic today announced it has acquired INSIGHT, a software provider with a formidable history of more than 40 years in the supply chain design space serving some of the most illustrious companies in the world. 
• ZS Associates: From its web site “When the forces of sales and marketing combine, the impact can be incredible. Together, they have the power to boost market share, increase revenue, lower costs and improve overall business performance.”
