Marisa Silva, the author of the PRINCE2 V7 scenarios, discusses the real-life applicability of the scenarios described in the PRINCE2 V7 framework. The scenarios aim to represent practical situations where decisions in projects might not always be made through formal channels. Silva gives examples of decisions made informally rather than through structured discussions with project boards or steering committees. Additionally, she emphasizes the importance of communication among team members, highlighting how casual conversations can ensure a shared understanding of the project's objectives. The scenarios also provide insights into resolving project issues and risks. Silva's objective is to showcase various real-world situations in the book, providing readers with tangible examples to contextualize the PRINCE2 concepts.
