Scrum’s Process Control Basis
Understanding the foundational principles of Scrum is crucial for effectively implementing and benefiting from this agile framework. One of these principles is the type of process control upon which Scrum is based.
Exam Question
Upon what type of process control is Scrum based?
(choose the best answer)
A. Defined
B. Complex
C. Empirical
D. Hybrid
Correct Answer
C. Empirical
Explanation
Correct Answer
Empirical (C):
Scrum is based on empirical process control, which relies on the three pillars of transparency, inspection, and adaptation. Empiricism means making decisions based on what is known, derived from actual experience and observation, rather than theoretical or predictive models. This approach is well-suited to complex, unpredictable environments where requirements and solutions evolve through collaboration and iterative progress.
Incorrect Answers
Defined (A):
Defined process control relies on a fixed, linear sequence of steps that must be followed precisely to achieve predictable outcomes. This approach works well in stable, predictable environments but is not suited to the dynamic, complex nature of most product development efforts addressed by Scrum.
Complex (B):
While Scrum is designed to handle complex problems, it is not based on “complex” as a process control. Instead, it uses empiricism to navigate complexity.
Hybrid (D):
Hybrid models combine elements of different methodologies but Scrum adheres strictly to empirical process control.
Responsibilities in Scrum
- Product Owner: Ensures the Product Backlog is ordered and refined to maximize value and align with the team’s capacity. Develops and explicitly communicates the Product Goal. Creates and clearly communicates Product Backlog items. Represents the needs of many stakeholders in the Product Backlog. Optimizes the value of the work the Scrum Team does by making informed decisions on the Product Backlog.
- Scrum Master: Coaches the team in Scrum practices, removes impediments, and facilitates team events to ensure productivity and adherence to Scrum principles. Helps everyone understand Scrum theory and practice within the Scrum Team and the organization. Ensures that Scrum events are productive and kept within the timebox.
- Developers: Collaborate to create the Sprint Goal and the Sprint Backlog, ensuring all work aligns with the Sprint Goal. Complete all tasks necessary to deliver a potentially shippable Increment, including ensuring that all Product Backlog items meet the Definition of Done.
Relevance to the PSM I Exam
Understanding the empirical basis of Scrum is essential for the PSM I exam. This principle underpins many of the framework’s practices and is crucial for correctly answering questions related to Scrum’s foundational concepts.
Key Takeaways
- Empirical Process Control: Scrum relies on transparency, inspection, and adaptation to navigate complex environments.
- Defined Process Control: Suitable for predictable environments, not for Scrum.
- Scrum Roles and Responsibilities: Key for effective implementation and exam success.
Conclusion
Grasping the empirical nature of Scrum is crucial for its successful application and for passing the PSM I exam. For comprehensive preparation and practice exams, check out PSM I Exam Prep to enhance your understanding and application of Scrum principles.
