HC Deb 24 September 1948 vol 456 c178W
Mr. Marples

asked the Minister of Works what data his Department has collected by time and motion study methods on the productivity of the building trades operative and if he will publish the statistics available.

Mr. Key

The object of time and motion studies undertaken by my Department has been to discover the best methods of carrying out certain operations, particularly connected with the erection of non-traditional houses and the use of new types of plant. They are not sufficiently comprehensive to yield statistical data about the general productivity of building trades operatives.
