Shaking vs Stirring

As a general rule, shaking is a vigorous activity therefore a shaken drink chills and dilutes at a much faster rate than a stirred drink. Shaking also aerates the liquid and adds texture to the cocktail. Stirring, being a gentler activity requires more time than shaking to get the drink to the right temperature and dilution. Generally, a stirred drink such as a Negroni tends to be not as cold as a shaken one such as a Daiquiri.
