In an enterprise that has worldwide business units and a centralized financial control model, which of the following is a barrier to strategic alignment of business and IT?

Each business unit having its own steering committee for IT investment and prioritization would *support* strategic alignment by allowing IT initiatives to be tailored to local business needs.

Uniform portfolio management applied throughout worldwide business units can be a barrier to strategic alignment because it may not allow for the flexibility needed to address unique local market conditions, regulatory requirements, or distinct business unit strategies. This centralized, uniform approach can stifle innovation and prevent IT from adapting quickly to specific business unit needs, thus impeding their individual strategic alignment.

IT being the exclusive provider of IT services to business units fosters a centralized approach, which, while having its own pros and cons, does not inherently create a barrier to strategic alignment; it can even enable it if managed effectively.

The enterprise's CIO being a member of the executive committee is a strong enabler of strategic alignment, ensuring IT is represented at the highest level of business decision-making.
