Maintaining and managing a product backlog across multiple Scrum teams can be a challenging endeavor. It requires effective coordination, communication, and alignment of priorities across all teams. However, with the right strategies and methodologies, this daunting task can be accomplished efficiently. In the context of the Certified Scrum Professional-Product Owner (CSP-PO) exam, let’s explore two methods for supporting product backlog management across multiple Scrum teams: the Scrum of Scrums and the Nexus framework.
1. Scrum of Scrums:
This approach aims to scale Scrum upwards by bringing together representatives from various Scrum teams. This representative could be the Scrum Master, a team delegate, or even the Product Owner. This assembled group then coordinates and aligns their teams’ efforts, enabling effective backlog management.
Here’s a practical example of how Scrum of Scrums can play out: Suppose you have three Scrum teams, each working on different features of a software application. A representative from each of these teams convenes every day in a Scrum of Scrums meeting. Here, they discuss progress, impediments, and dependencies. This meeting helps manage the product backlog efficiently as it provides insights into which items are being tackled and which ones need to be prioritized or reassigned.
Table 1: Scrum of Scrums vs. Individual Scrum teams
| Scrum of Scrums | Individual Scrum Teams | |
|---|---|---|
| Scaling | Designed to scale across multiple teams | Best suited for single teams |
| Backlog management | Centrally managed by representatives of each team | Managed by individual Product Owner |
| Communication | Facilitated through representative | Facilitated through Scrum Master and Product Owner |
| Dependencies | Managed across teams | Managed within the team |
2. Nexus Framework:
Nexus is a framework that extends Scrum to guide multiple Scrum teams working on a single product backlog. It consists of roles, events, and artifacts that bind and weave the work of approximately 3 to 9 Scrum Teams working on a single Product Backlog to build an Integrated Increment(Rehkopf, 2016).
In essence, Nexus is a Scrum exoskeleton that lays on top of multiple scrum teams. It was designed by Ken Schwaber, the co-creator of Scrum, and seeks to address the challenges of scale by minimizing dependencies and integration issues among teams.
To illustrate, let’s assume four Scrum teams are working on a web application. These teams will have separate meetings (daily scrum), but they also participate in Nexus events, where integration and alignment of backlog items are discussed. A Nexus Integration Team, which includes the Product Owner, Scrum Masters, and an Integration Team Member from each team, manage the flow of work and resolve dependencies.
Table 2: Nexus vs. Individual Scrum teams
| Nexus | Individual Scrum Teams | |
|---|---|---|
| Scaling | Designed to scale across multiple teams | Best suited for single teams |
| Backlog management | One product owner manages backlog for all teams | Managed by individual Product Owner |
| Communication | Facilitated through the Nexus Integration Team | Facilitated through Scrum Master and Product Owner |
| Dependencies | Managed across teams | Rely on Scrum of Scrums to manage dependencies |
In conclusion,
both the Scrum of Scrums and Nexus offer practical ways of managing a product backlog across multiple Scrum teams. They facilitate the coordination and communication necessary to ensure that all teams are aligned towards the same product goal. Adoption of these methods will, however, depend on your organization’s needs, size, and work culture.
Practice Test
True or False: One method to support product backlog management across multiple Scrum teams is to maintain a single backlog.
- True
- False
Answer: True
Explanation: A single backlog ensures a single point of control and reduces tasks duplication across Scrum teams.
The Scrum Master is responsible for ensuring the Product Backlog items are communicated across the scrum teams.
- True
- False
Answer: False
Explanation: The Scrum Master helps to remove obstacles, but Product Owners are responsible for managing and communicating the backlog items.
What are the commonly used methods to support Product Backlog management across multiple Scrum Teams?
- A. Scrum of Scrums
- B. Nexus
- C. Waterfall method
- D. Agile Scaling
Answer: A, B, and D
Explanation: Scrum of Scrums, Nexus, and Agile Scaling techniques are typically used to manage multiple Scrum Teams. Waterfall method is not applicable here as it is not a framework or a technique to handle multiple scrum teams.
True or False: It is important to align the team’s understanding of the project vision and goals in managing product backlog across teams.
- True
- False
Answer: True
Explanation: Aligning the team’s understanding of project vision and goals helps in collaborative decision making and effective backlog management.
A Product Owner should use different sets of product backlog for each scrum team.
- True
- False
Answer: False
Explanation: A unified product backlog helps to circumvent the possibility of different teams working on similar items thus reducing redundancy.
True or False: The LeSS framework allows coordination of large-scale Scrum projects across multiple teams.
- True
- False
Answer: True
Explanation: The Large-Scale Scrum (LeSS) is a framework that provides structure for applying Scrum principles to large product development.
The Chief Product Owner is the best role for managing the backlog for multiple Scrum teams.
- True
- False
Answer: True
Explanation: The Chief Product Owner can prioritize and delegate backlog items effectively across multiple Scrum teams.
Which of the following roles need to regularly interact with the Product Backlog?
- A. Scrum Master
- B. Product Owner
- C. Development Team
- D. Stakeholders
Answer: A, B, C, D
Explanation: All of them – the Scrum Master, Product Owner, Development Team and Stakeholders – interact with the Product Backlog at different stages and for different reasons.
True or False: The Daily Scrum Meeting can be used as a method to support product backlog management.
- True
- False
Answer: True
Explanation: Daily Scrum meetings promote communication and transparency, which help with the process of backlog management.
In Scrum, the responsibility of ‘Backlog Refinement’ is owned solely by the Product Owner.
- True
- False
Answer: False
Explanation: Though the Product Owner plays a major role, the Development Team also participates in backlog refinement – refining items and providing estimates.
Interview Questions
