To proceed with the project, which Asus code-named "Project A-Team", the company sent a design team to Google's headquarters in Mountain View, California, while Google sent seven engineers to Asus' headquarters in Taiwan. Having employees working in both locations allowed the engineering team to have a 24-hour development cycle, although Shih later needed to add 40 people to the project to meet Google's requests. The design for the Nexus 7 was based on a tablet that Asus had showcased at International CES that year, the Eee Pad MeMO ME370T. An official explained, "While the base design and setup was completed in the 370T to meet a certain price point and option list, the efforts required to get that design to $199 meant going back to the drawing board and starting over on just about every aspect of the unit. " Among the component modifications were a new motherboard, revised system on a chip (SoC), laminated display, and rear casing with a grippier material. The Nexus 7's design was completed after a relatively rapid four-month development period; mass production began in May 2012.
