An IT strategy committee wants to evaluate how well the IT department supports the business strategy. Which of the following is the BEST method for making this determination?

A capability maturity assessment evaluates the maturity of processes and capabilities within IT, which is valuable but does not directly measure IT's alignment with or contribution to overall business strategy.

Customer survey analysis provides valuable feedback on IT services and satisfaction but represents only one perspective of IT's strategic alignment and does not offer a comprehensive view of overall business strategy support.

An IT balanced scorecard provides the best comprehensive method for evaluating IT's strategic alignment by measuring performance across multiple dimensions-financial, customer, internal processes, and learning and growth. This directly links IT objectives and outcomes to overarching business strategy and value delivery, offering a holistic view for the committee.

An IT controls assurance program focuses on the effectiveness of internal controls and risk management, which are aspects of good governance, but it is not primarily a tool for measuring strategic alignment with business objectives.
