A pair of engineers, pioneers in the study of time and methods to increase the productivity of industries, apply their peculiar professional procedures to direct -or, at least, attempt- their twelve sons, six girls. and six children. This system of family organization is sometimes quite useful: children are the most diligent in learning to type, calculate, read, advance courses in school... But, as expected, not everything is so simple, and the comic and crazy situations are unstoppable in this novel (written by two of the couple's children) that will make even the most serious readers laugh.
