Productivity of computer-dependent workers

Given the methodology and tools, the major barrier to carrying out productivity studies of the kind discussed in this paper is our ignorance of certain system and usage characteristics. Clearly, the first order of business is to develop measurement techniques so as to provide the required data. A review of this paper makes it evident that the kinds of data needed are the following: • System congestion characteritics, as illustrated in Figure 2. • Usage characteristics, t
