Scrum vs DSDM Prioritization

5 minutes 5 Questions

Scrum and Dynamic Systems Development Method (DSDM) handle the prioritization of work differently. In Scrum, the product owner is mainly responsible for prioritizing the product backlog items, taking into account business value, dependencies, risk, and other factors. On the other hand, DSDM uses a MoSCoW prioritization method (Must have, Should have, Could have, Won’t have) that the whole team collaboratively works on to prioritize the project’s requirements.

Guide on Scrum vs DSDM Prioritization

This guide will help you understand the differences between Scrum and DSDM when it comes to prioritization, why it is important, and how it works. It will also provide tips on how to answer exam questions on Scrum vs DSDM Prioritization.

Importance and What it Is:

Scrum and DSDM are both Agile frameworks that focus on delivering high value products in short timeframes, but they approach prioritization differently. In Scrum, the Product Owner prioritizes the product backlog based on value, risk, and necessity- this is a major role in the Scrum Team. In DSDM, the prioritization is based on the MoSCoW method- Must have, Should have, Could have, and Won’t have at this time. Prioritization is key in project management as it helps to decide what to focus on in case of limited resources. It also facilitates risk management.

How it Works:

In Scrum, the Product Owner, after gathering inputs from all stakeholders, uses their judgment to prioritize the work. The most essential elements for product success are worked on first. Whereas in DSDM, the whole team is involved in the prioritization process using the MoSCoW rules and, the work is categorized as indicated above. The 'must have' tasks are always completed first.

Exam Tips: Answering Questions on Scrum vs DSDM Prioritization:

To answer exam questions about Scrum and DSDM prioritization:

1. Understand the key roles in each framework and who does the prioritization.
2. Familiarize yourself with the MoSCoW method and what each category entails.
3. Prepare to compare and contrast the two prioritization methods.
4. Practice explaining why prioritization is important in Agile project management.
5. Learn how to apply these methods in real-world situations.

Question 1

Being a Scrum Master in a project where the constant iterations of the product versioning are immensely needed, and adaptation to the market is crucial. Which is the best method to cope with this situation?

Correct Answer: Scrum due to its adaptability and quick iteration cycles

The question revolves around a project scenario that requires frequent iterations and quick adaptation. Scrum methodology is designed specifically for such situations. It prioritizes adaptability and quick iteration cycles, allowing teams to respond effectively to changes. This makes it the most suitable for this case. Now analyzing the incorrect answers: 'DSDM due to its pre-fixed delivery schedules' - DSDM can be less flexible due to its pre-set schedules, making it less suitable for a project needing frequent adaptations. 'Ignore both Scrum and DSDM, follow strict sequential development' - Sequential development lacks flexibility and adaptability as compared to Scrum which is not suitable for projects where market adaptation is crucial. And 'Scrum but avoid iterations and develop in a single go' - This essentially negates the very nature of Scrum, which is based on iterative development. Hence it is also an incorrect option.

Question 2

In a complex project, the most important requirements are unclear and may change over the course of the project. Which implementation would best meet these needs?

Correct Answer: Scrum, because it is adaptive and iterative

In complex projects where requirements are unclear or dynamic, Scrum is the ideal implementation model. Scrum is adaptive and iterative, which means it allows room for constant evaluation and changes. Therefore, if the requirements change over time, Scrum can adapt accordingly. On the other hand, DSDM relies on defining all requirements upfront, which wouldn't work when requirements are unclear and are subject to change. Scrum having larger teams or DSDM using formal roles has no influence on the flexibility needed to handle uncertain and changing requirements.

Question 3

You're a Scrum Master dealing with a project where stakeholders require frequent delivery of products, expect constant change, and deadline is flexible. How will you tackle the priorities?

Correct Answer: Choose Scrum for its iterative and incremental approach.

The situation mentioned in the question is best suited to Scrum because it is designed for projects with frequent changes, need for early and constant delivery and can accommodate flexible deadlines. Scrum is an iterative and incremental framework that allows for flexibility while maintaining regular output of usable product increments. This makes Scrum the ideal choice based on the conditions mentioned in the question. DSDM, on the other hand, is a strict time-boxing agile method that wouldn't well adapt to constant changes as it prioritizes delivery in terms of timeboxes. The concept of using both Scrum and DSDM together would conflict as both of them have different mechanisms of handling work. Rejecting both Scrum and DSDM isn't a sensible solution here because Scrum is well-suited for such environment based on the details provided.
