The employees who agreed to participate in the test of the plan were among the company's most self-motivated and independent workers.

The savings that would accrue from reduced office-space expenditures alone would be sufficient to justify the arrangement for the company, apart from any productivity increase.

Other companies that have achieved successful results from work-at-home plans have work forces that are substantially larger than that of XYZ.

The volunteers who worked at home were able to communicate with other employees as necessary for performing the work.

Minor changes in the way office work is organized at XYZ would yield increases in employee productivity similar to those achieved in the trial.
