Studies of this kind assume that it is possible for a researcher to understand the world from
the view of an employee – not easy even if the researcher comes from the same country.
There are also practical limitations on the approach because employees may not welcome
such in-depth observation.
Also, the time the study takes and the problem of analysing the wealth of data that
emerges (for instance, from hourly interviews) make it an expensive approach.
Finally, the use of the conclusions may only extend to understanding internal or group
culture, but may not offer any practical solutions for improvements.
