Scrum supplies the core framework (roles, events, artifacts) for empirically building products, but it is intentionally lightweight. AgilePM (based on DSDM) complements Scrum by offering a well-tested pool of practices, tools, and techniques that strengthen day-to-day delivery and governance without altering Scrum’s essence. Typical enhancements include MoSCoW prioritization to manage variable scope, timeboxing to protect cadence, facilitated workshops and modeling to accelerate shared understanding, and explicit roles for business involvement to improve decision flow. AgilePM also provides guidance on project-level controls—such as business cases, incremental release planning, and benefits focus—that sit outside Scrum’s product-delivery scope. For a Scrum Master, this combination is valuable: Scrum remains the engine of iterative delivery, while AgilePM offers practical methods to refine backlog refinement, clarify acceptance criteria, manage dependencies, and support predictable delivery against time and cost constraints. Thus, the pairing gives Scrum Masters a richer toolkit to coach teams, align stakeholders, and handle real-world project contexts where governance, prioritization, and incremental release structures are needed—precisely what option B describes.
