When discovering that a selected solution no longer meets the organization's scalability needs, the most logical course of action is to review the original solution set to find an alternative that aligns with the organization's risk appetite, budget, and compliance requirements.

Issue Identification:

Scalability issues mean the solution is not fit for purpose.

Proceeding with the implementation risks wasting resources and failing to meet organizational needs.

Best Approach:

Reassess the available options from the original evaluation.

Ensure the alternative solution meets both functional and regulatory requirements.

Other Options:

B & C: Continuing the implementation with unresolved scalability issues could lead to operational failures.

D: Canceling the project based solely on internal requirements disregards the broader business context.

Risk-Based Decision Making: Encourages reassessing alternatives when new risks are identified.

Project Management Principles: Stresses alignment of solutions with business needs and compliance requirements.
