Given that employees of the XYZ Company could, in theory, do their work at home, the company developed a radical plan to increase efficiency: eliminate office-space expenditures by having employees work at home  To evaluate this plan, XYZ' s managers asked volunteers from the company' s staff to try the arrangement for six months
There were several volunteers; significantly, their productivity during this period was as high as or higher than before
The savings that would accrue from reduced office-space expenditures alone would be sufficient to justify implementation of the plan apart from any productivity increases.
