What are two reasons to manage an implementation plan as a Roadmap? (SAFe SPC exam exercise, personally I would select the 1st and the 4th option)

• This form of plan supports preserving options as an aspect of look-ahead planning
• It allows the teams to ensure executives are not over-controlling the implementation process
• It creates a visible radiator for the Lean-Agile Center of Excellence (LACE) daily stand-ups
• Organizations, including stakeholders, will more quickly acclimate to, and adopt, an orderly visual plan for transformation
• It allows teams to commit, in advance, to no more than nine months of the Implementation Roadmap, making it more Agile
