Which Lean budget Guardrail helps ensure the appropriate allocation of budgets to balance near- term opportunities with long-term strategy and growth?

Lean Budget Guardrails are policies that provide governance and spending oversight for a SAFe portfolio. The guardrail "Guiding investments by horizon" specifically addresses the need to balance near-term and long-term goals. It ensures that a portfolio allocates its budget across three investment horizons: Horizon 1 (defending and extending the current business), Horizon 2 (emerging new opportunities), and Horizon 3 (exploring future, potentially disruptive options). This practice prevents the portfolio from focusing solely on immediate features at the expense of innovation and future growth.

A. Applying capacity allocation ensures that budget is dedicated to both new features and maintaining existing solutions, but not the long-term strategic horizons.
B. Approving significant initiatives is a guardrail that ensures large investments are properly vetted, but it doesn't inherently balance near- and long-term strategy.
D. Continuous Business Owner engagement ensures that development aligns with business needs, but it is not the specific mechanism for balancing investment horizons.
