Manager: Support Our new computer network, the purpose of which is to increase productivity, can be installed during the day, which would disrupt our employees' work, or else at night, which would entail much higher installation charges. █████ ██████ █████ ██ ██████████ ██ ██████ ████ ███ ███████ █████████ ██████ ███ ████
Summary
The manager argues that the new network should be installed during the day rather than at night. This is because saving money is important, and though daytime installation disrupts the employees’ work, nighttime installation has a higher price tag.
Notable Assumptions
There are a couple of notable assumptions here. The manager says that saving money is important, but not that saving money is the most important or only consideration. So it assumes that there are no advantages to installing the equipment at night that outweigh cost concerns.
Also, while the installation cost is higher at night, it’s entirely possible that the disruption of the employees’ work during the day would cost the company even more money, so the manager must assume that this wouldn’t be the case.

The monetary value ██ ███ ███████ █████████ █████ ███ ██████ ███ ████ ██ ██████ ███ █████████ █████████ ██ ██████
The relevant comparison is between the cost of installation during the day versus at night—the equipment costs the same amount regardless of what time of day it’s installed.

This must be true in order for the conclusion to follow. If the interruptions to employees’ work would cause the company to lose more money than the price of nighttime installation, then nighttime installation would save more money.

A daytime installation █████ ██ █████████ ██ ██ ██████ █ ████ ███ █████ ████ ███ ████ ██ ████ ████ ████ █████ █ █████████ █████████████
Daytime installation could still cost less even if it involved a larger and slower crew, so this assumption isn’t necessary.

The time it takes for the network to become useful is irrelevant to the cost comparison of daytime versus nighttime installation. The network’s productivity would be the same regardless of when it was installed.

The manager doesn’t need to assume that the workers will be productive during a daytime installation, just that their decrease in productivity would not cost the company more than the price of a nighttime installation.
