What type of outsourcing model involves a fee that varies with user access levels?

The choice of the Usage Model is appropriate because it directly correlates costs with the level of user access and utilization of services. In this model, service fees are structured around the actual usage or access levels by users rather than a fixed fee. This means that organizations are charged based on how much they use the service, making it a flexible option that can adapt to changing needs or varying user levels.

For example, if an organization has employees who only occasionally access a system, they will pay less compared to a scenario where a larger number of users regularly interact with the system. This model incentivizes efficient usage and can lead to cost savings for both the provider and the client.

In contrast, other models do not typically vary costs in relation to usage. For instance, the Method Model may focus on a predetermined methodology rather than user access, the Cost-Plus Model involves reimbursement of costs plus a fixed margin, and the Performance-Based Model typically centers on incentive structures based on service outcomes, rather than direct usage levels.
