Support The companies that are the prime purchasers of computer software will not buy a software package if the costs of training staff to use it are high, and Support we know that it is expensive to teach people a software package that demands the memorization of unfamiliar commands. ██ █ ███████ ██ ██ ███████████ ██████████ ████████ ████████ ██████ ███████ █████ ██ ████████ ██████████ █████████
Summary
The argument concludes that in order to be successful, the software cannot demand memorization of unfamiliar commands. This is based on the following two premises:
If training costs are high, prime purchasers of the software won’t buy it.
If a software demands memorization of unfamiliar commands, then the training costs are high.
Missing Connection
We want to reach the conclusion that if a software demands memorization of unfamiliar commands, it won’t be successful. “Won’t be successful” is a new concept in the conclusion; the premises don’t tell us what leads to lack of success.
But we do know from the two premises together that if a software demands memorization of unfamiliar commands, the prime purchasers won’t buy it.
If we learn that “prime purchasers won’t buy” establishes “unsuccessful,” that will establish that if a software demands memorization of unfamiliar commands, it won’t be successful. In other words, we want to learn that in order to be successful, a software needs prime purchasers to buy it.
