The Nexus Framework

Correct Answer: Implement daily scrums to discuss work since the last meeting and work to be done before the next one.

The most efficient method to enhance coordination within a Nexus would be to 'Implement daily scrums to discuss work since the last meeting and work to be done before the next one.' These scrum meetings promote open communication, transparency, and immediate addressing of any issues or impediments. This helps all team members stay aligned on the progress towards the goal and the steps to be taken further, increasing effectiveness and productivity. Daily scrums not only focus on the progress but also the challenges that lie ahead, making the team proactive and readyThe option 'Leverage e-mail communication to minimise misunderstanding.' does not promote real-time communication and swift resolution of issues. E-mails may not be checked immediately, leading to delays, and there might be information loss or misunderstanding due to the lack of real-time interaction and instant feedbackSimilarly, the option 'Attend only pre-planned meetings to discuss the issues.' lacks the continuous feedback mechanism. It does not promote daily updates on the plan and impedimentsThe option 'Promote single directional communication to avoid conflicts.' runs against the principles of scrum which encourages interaction, feedback and team collaboration. Single directional communication often leads to misunderstanding, lack of clarity and meager feedback.

Correct Answer: Regularly integrate & validate their work with other teams

In a Nexus, the Scrum Teams should 'Regularly integrate & validate their work with other teams'. This is because the Nexus framework emphasizes continuous integration among multiple Scrum teams working on the same product, to ensure consistent progress and to identify any conflicts or issues early. 'Work separately and integrate at the end of the Sprint' is not the best practice, as this can lead to conflicts and inconsistencies that are only discovered at the end of the Sprint, not allowing enough time for resolution. 'Work and manage their respective Sprint Backlogs independently, without syncing with others' and 'Avoid cross-team coordination to maintain focus on their tasks' are incorrect because these approaches go against the principle of collaboration and communication in the Nexus framework. Syncing and coordinating help in establishing a shared understanding of the product and maintaining consistency.

Correct Answer: Refine Product Backlog items to minimize dependencies and try to make items 'ready'

The best approach to managing numerous dependencies between items in the Product Backlog is to refine the Product Backlog items in an effort to minimize these dependencies and make items 'ready.' This approach falls directly within the responsibilities of the Scrum Team and utilizes the process of backlog refinement—an ongoing activity to add detail, estimates, and order to the items. Clear, actionable, and 'ready' backlog items enable a smoother, more efficient development process. As for the other answers, they are not as efficient or effective in a Scrum environment. Letting the individual teams manage heavily interdependent items could lead to bottlenecks and inefficiencies. Removing the dependent items from the backlog is not a good solution as these items are likely still necessary for the product. Requesting the Product Owner to reduce the number of dependencies might be helpful, but it's ultimately up to the entire Scrum Team to work together to manage and minimize them as part of the refinement process.
