The article he wrote about Marriott's choice to continue using its z/TPF based platform over migrating to Starwood is also telling. https://www.linkedin.com/pulse/marriottstarwood-back-future-technology-decision-israel-del-rio/ https://www.linkedin.com/pulse/marriottstarwood-back-future-... See this quote "To better understand the resulting Starwood’s technology compared to industry legacy systems, think Tesla Model S versus a gas-guzzling 1975 Buick Electra. Then along came Marriott . . . When Marriott announced its interest in acquiring Starwood, one would have believed that they factored in a $500 million Starwood IP technology value within their $13.6 Billion offer, and that they would have been salivating at the prospect of having their hands on the fruits of the multi-year transformation experience this IP represented. After all, while stable as a rock, Marriott’s own system today centers around 1970’s Mainframe TPF technology (MARSHA) suitably kept current via the judicious use of the scotch-tape and wires represented by a cornucopia of front-end gateways and the labor intense support of inflexible legacy code, eclectic data bases, hard-coded interfaces, and a veritable zoo of different property management systems crying for better integration. " It reads as sour-grapes to me.
