A recently purchased IT application does not meet project requirements. Of the following, who is accountable for the potential impact?

A business analyst is responsible for defining requirements, but not for the ultimate accountability of project success or failure.

The project sponsor is the individual who champions the project, provides resources, makes high-level decisions, and is ultimately accountable for the project's overall success and its alignment with business objectives. If an application fails to meet requirements, the sponsor bears the ultimate accountability for the impact on the business, as they are responsible for ensuring the project delivers its intended value.

The IT project team is responsible for executing the project, but the project sponsor holds the ultimate accountability for the project's success.

The IT Project Management Office (PMO) provides governance, standards, and support for projects, but the accountability for a specific project's success lies with its sponsor.
