The portfolio Vision is not simply an aggregation of the ARTs’ Visions. Instead, the portfolio Vision is a higher-level, strategic expression of the portfolio’s direction and purpose, informed by the enterprise strategy and objectives. While ART Visions may align to and support the portfolio Vision, the portfolio Vision is created at the portfolio level and provides the overall context for the ARTs, not the other way around.
