This study first searched the theoretical background of programmar productivity related with white coller productivity and carried an empirical study for improving the productivity.
In experimental study, productivity was not measured by programming cost but by central processing unit time(qualitative aspects), and it was analyzed by COBOL language and 16 bit personal computer.
Also, three file organization method and three access method were selected with this experiment.
The experiment was conducted with test data for a programs by individual programming. The result was that relative file is more efficient regardless of updated ratio in file organization and dynamic method of random method is more efficient in file access method in case of 500 updated data, random access method in more efficient in the other cases.
Also sequential was more efficient in input in case of 500 updated data, and relative file was efficient in output.
