The book with 23 chapters required specialization expertise from different fields of macroeconomics, biology and mathematics. Our biggest challenge was to provide expertise pertaining to each subject while maintaining consistency by not using multiple translators, even though there were multiple subjects. Maintaining formatting consistency of the translated file with the source file was a pivotal requirement of Mr. Takayuki. This was a complex task as the source file was a PDF which contained innumerable equations, figures, and tables that needed to be replicated in the translated file as it is.
