Final answer:
The best approach to convince stakeholders of COBIT 5's value depends on their preferences: a cost-benefit analysis for quantitative evidence, success stories for narrative evidence, workshops for experiential learning, or high-level overviews for a concise introduction. All options are correct.
Step-by-step explanation:
The quickest and best way to convince key executives and other stakeholders of the value of using COBIT 5 depends on the audience's preferences and the context in which you're operating.
Option 1, presenting a comprehensive cost-benefit analysis, is a foundational method that can provide a clear and quantifiable understanding of the savings and efficiencies to be gained by adopting COBIT 5. This method aligns well with the decision-making process as it involves weighing marginal costs against marginal benefits. A cost-benefit analysis chart can graphically represent these comparisons to aid in decision-making.
However, Option 2 might be more effective if the stakeholders relate better to narrative evidence. Sharing success stories and case studies can illustrate the practical benefits of COBIT 5 in a more relatable manner, revealing its real-world impact on other organizations.
Option 3, organizing a workshop or training session, allows stakeholders to get hands-on experience with COBIT 5, potentially translating its theoretical advantages into practical understanding. Yet, if the stakeholders prefer a more distilled and less time-intensive approach, Option 4's high-level overview could suffice to garner initial interest without overwhelming them with technical details.
In summary, it is advisable to know your audience and perhaps combine these approaches strategically to maximize understanding and appeal.
Hence, all of the given choices are correct.
