Monthly feedback and training sessions are the best approach to ensure that the deliverables of a critical business initiative are increasingly adopted and leveraged by the organization over time. Feedback and training sessions are communication and learning activities that provide information and guidance on how to use and benefit from the new processes and technology introduced by the initiative. Feedback and training sessions can help to increase awareness, understanding, acceptance, and adoption of the deliverables among the organization's employees and stakeholders. They can also help to identify and address any issues or challenges that may arise during the implementation and transition phases.

The number of items in the backlog can be determined by looking at the "Commitment" column for each sprint in the provided chart. For Sprint 5, there is a commitment of completing 23 items, which is the highest among all sprints. This indicates that there are at least 23 items in the backlog to be worked on. This is consistent with the concept of agile project management, which allows for changes and additions to the project scope based on customer feedback and changing requirements.

Quantitative risk analysis involves numerically analyzing the effect of identified risks on overall project objectives. It often includes assigning monetary values to risks to understand their impact in financial terms, helping in prioritizing risks based on their potential cost or impact on the project. This contrasts with qualitative risk analysis, which assesses risks based on their probability and impact but does not assign numerical values.

The project manager should ask the developer to create a change request, which is a formal document that describes the proposed change, its benefits, costs, risks, and impacts on the project scope, schedule, budget, and quality. A change request is the first step in the change control process, which involves evaluating, approving, or rejecting changes to the project baselines. The project manager should not do nothing, because ignoring the recommendation could result in poor performance and customer dissatisfaction. The project manager should not ask the developer to implement the recommendation without following the change control process, because that could cause scope creep, which is the uncontrolled expansion of the project scope without proper authorization or adjustment of the project resources and objectives. The project manager should not communicate the change status before the change request is submitted and approved, because that could create confusion and false expectations among the project stakeholders.
