The suggested answer C is agreed.
The best way for IT to prepare for a transformation initiative leveraging emerging technology is to assess the impact on the existing IT strategy.
Reasoning:

Assessing the impact on the existing IT strategy allows the enterprise to understand how the introduction of emerging technology aligns with current IT objectives, capabilities, and the IT roadmap. This assessment identifies potential gaps, challenges, and opportunities that may arise from the transformation initiative.
The IT strategy serves as the foundation for all IT activities. Ensuring alignment between the IT strategy and the transformation initiative is crucial for the initiative's success. If the IT strategy is misaligned, the initiative is likely to fail.
By assessing the impact, IT can proactively adapt its strategy, infrastructure, and processes to effectively support the new technology and achieve the desired outcomes of the transformation.

Reasons for not choosing the other answers:

A. Procure appropriate resources to support emerging technology: While procuring resources is important, it's a reactive step. A proactive approach involves first understanding the impact on the IT strategy. Procurement without strategic alignment can lead to inefficient resource allocation.
B. Use a balanced scorecard to measure IT outcomes: A balanced scorecard is a performance measurement tool. While useful for monitoring progress and outcomes, it doesn't directly prepare IT for the change itself. It's more of a post-implementation monitoring activity.
D. Analyze emerging technology products and related training needs: Analyzing products and training needs is important, but it should follow the assessment of the IT strategy. The analysis should be guided by the strategic alignment identified in the IT strategy assessment. Without strategic alignment, the product analysis may not be relevant or efficient.
