Final answer:
The correct answer is (a), as scalability is a reason to subscribe to on-demand software, not a rationale against it. Other options are legitimate reasons to consider such a subscription, tailored to businesses with specific IT constraints.
Step-by-step explanation:
The question poses a scenario regarding the subscription to on-demand software, and the correct answer is to identify which of the given options is not a reason for subscribing to such services. Option (a) 'the software does not need to be scalable' is not a reason to subscribe to on-demand software. Scalability is typically one of the significant advantages of on-demand software, allowing businesses to adjust their use of software based on their current needs without significant upfront investments.
Options (b), 'specialized software is needed in a timely fashion', (c), 'the IT staff does not include developers', and (d), 'the company has limited storage capacity', are all valid reasons to consider on-demand software. These reasons reflect the common challenges that on-demand or cloud-based software solutions are designed to address, especially for businesses that require flexibility, have no in-house development capabilities, or have limited infrastructure.
