The project manager should propose a governance model that empowers the teams while providing the necessary oversight to the executive leadership team (Option B). This approach is based on the principle that in an Agile transformation, the focus shifts from controlling to empowering teams1. The governance model should be designed in a way that it provides the necessary oversight to the executive leadership team without stifling the agility of the teams1.
Ensuring that the executive leadership team approves all scope that is being proposed by the multiple agile teams to avoid misalignment (Option A) may not be practical or efficient as it could slow down the agile process1. Proposing a multilayered gate system based on risks and financial expenditures, involving the executive leadership team as needed (Option C) may add unnecessary complexity and could potentially slow down the agile process1. Assuring the executive leadership team that the current governance model will not be affected by the agile approach (Option D) may not be accurate as an Agile transformation often requires changes in the governance model1.
