Innovation never rests within Agile methodologies; witness the Nexus Framework - an approach that's revolutionizing team collaboration and streamlining efforts. In this comprehensive guide, we delve deep into this approach's unique benefits while showing its seamless fit with Scrum methodology. Whether an avid Agile fan or curious learner alike, prepare to discover more of this dynamic framework - an approach which promises exceptional project success!

What is the Nexus Framework? 

The Nexus Framework, a sibling of Scrum, was born out of the necessity to scale Scrum efficiently across multiple teams working on a single product. It addresses challenges arising from cross-team collaboration, communication, and integration, making it an ideal solution for large-scale projects. While embracing the core principles of Scrum, Nexus enhances them with added practices to ensure seamless cooperation among various Scrum Teams.

Nexus In Agile

Nexus is an agile scaling framework that builds upon the foundation of Scrum to enable multiple Scrum Teams to work together more effectively on a single product. It provides a lightweight and adaptable approach for organizations looking to scale Scrum practices while preserving the principles of agility. Nexus addresses the complexities of coordinating and integrating the work of multiple teams to deliver a cohesive product increment.

  • Scrum as the Foundation: Nexus is rooted in Scrum, which is a widely adopted agile framework for managing complex product development. Scrum emphasizes collaboration, iterative development, and continuous improvement through defined roles (Scrum Master, Product Owner, Development Team), events (Daily Scrum, Sprint Review, etc.), and artifacts (Product Backlog, Sprint Backlog, Increment).
  • Scaling Scrum: As organizations grow and undertake larger projects, a single Scrum Team may not be sufficient. This is where Nexus comes in—it provides guidance on how to effectively scale Scrum practices to accommodate multiple Scrum Teams while maintaining the core principles of transparency, inspection, and adaptation.
  • Framework Components: Nexus introduces specific roles and events to facilitate collaboration and coordination among Scrum Teams:
    • Nexus Scrum Master: This role focuses on cross-team collaboration, resolving dependencies, and facilitating Nexus events.
    • Nexus Sprint Planning: Teams collaborate to plan their work for the upcoming Sprint, considering dependencies and shared goals.
    • Nexus Daily Scrum: Representatives from each team participate in a Nexus Daily Scrum to address cross-team coordination and impediments.
    • Nexus Sprint Review: Teams showcase their individual increments and contribute to the integrated product increment.
    • Nexus Sprint Retrospective: Teams reflect on their collaboration and identify improvements for Nexus itself.
  • Integrated Increments: Nexus emphasizes the creation of an integrated product increment that represents the combined work of all Scrum Teams. Regular integration points ensure that individual team increments are compatible and can be combined seamlessly.
  • Empirical Process Control: Similar to Scrum, Nexus operates on the principles of transparency, inspection, and adaptation. Teams continuously inspect and adapt their processes, address dependencies, and collaborate to achieve the Nexus Sprint Goal.
  • Flexibility and Adaptability: Nexus doesn't prescribe a heavy set of practices. Instead, it offers guidelines that can be tailored to fit an organization's specific needs and context.
  • Value Delivery: The ultimate goal of Nexus is to enhance collaboration among Scrum Teams, remove obstacles, and deliver valuable product increments regularly.

The Core Principles of Nexus Framework

The Nexus Framework is built upon a set of core principles that guide its implementation and operation. These principles are designed to enhance collaboration, streamline communication, and optimize the work of multiple Scrum Teams working together on a single product. Here are the core principles of the Nexus Framework:

  • Transparency and Visibility: Transparency is a cornerstone of the Nexus Framework. Teams maintain clear visibility into each other's work, progress, and challenges. This transparency fosters open communication, enabling effective coordination and alignment across all teams.
  • Empirical Process Control: The Nexus Framework follows an empirical approach, where decisions are made based on observations and data. Regular inspection and adaptation ensure that the framework evolves to meet the changing needs of the project and the organization.
  • Shared Definition of Done: All Scrum Teams within the Nexus adhere to a shared Definition of Done. This standardizes the quality expectations for the increment produced by each team, ensuring that integration and delivery processes are seamless.
  • Nexus Integration Team (NIT): The NIT is responsible for facilitating collaboration and communication among the Scrum Teams. This cross-functional team includes representatives from each Scrum Team and ensures that dependencies are managed and resolved effectively.
  • Sprint Planning Nexus Event: Nexus Sprint Planning aligns the work of all Scrum Teams for the upcoming Sprint. During this event, teams review and refine the items in the Nexus Sprint Backlog and identify dependencies.
  • Nexus Daily Scrum: Teams participate in the Nexus Daily Scrum to synchronize their activities and discuss progress, impediments, and dependencies. This event enhances communication and promotes shared understanding.
  • Nexus Sprint Review: The Nexus Sprint Review is an opportunity for all Scrum Teams to showcase the integrated increment they've collectively developed during the Sprint. Stakeholders provide feedback, fostering collaboration and continuous improvement.
  • Nexus Sprint Retrospective: After the Nexus Sprint Review, all Scrum Teams come together for the Nexus Sprint Retrospective. This event focuses on improving the Nexus itself, identifying process improvements, and addressing obstacles that affect multiple teams.
  • Scaling Roles: While each Scrum Team retains its core roles (Scrum Master, Product Owner, Development Team), Nexus introduces the role of the Nexus Scrum Master. This role is responsible for facilitating Nexus events, removing impediments, and guiding the implementation of Nexus practices.
  • Incremental and Iterative Development: Nexus encourages the incremental and iterative development of the product. Scrum Teams work on individual increments, which are integrated into a single increment at the end of each Sprint.

Nexus Roles and Responsibilities

In the Nexus Framework, roles and responsibilities are structured to support the collaborative efforts of multiple Scrum Teams working together on a single product. These roles ensure effective coordination, communication, and alignment across teams. Here are the key Nexus roles and their responsibilities:

Product Owner (PO):

Responsibilities: The Product Owner remains responsible for defining the product backlog, prioritizing items, and ensuring that the work completed by the Scrum Teams aligns with the product's vision and goals.

Nexus-Specific Responsibilities: The Product Owner collaborates with the Nexus Scrum Master and other Product Owners to maintain a consolidated Nexus Sprint Backlog and prioritize work that spans multiple teams. The Product Owner ensures that dependencies are managed effectively.

Scrum Master:

Responsibilities: The Scrum Master facilitates the Scrum process, guides the team in adopting Scrum practices, and removes impediments to the team's progress.

Nexus-Specific Responsibilities: In the Nexus context, the Scrum Master of each Scrum Team collaborates with the Nexus Scrum Master to identify and address inter-team dependencies and obstacles that affect the overall Nexus

Development Team:

Responsibilities: Development Teams are responsible for creating the product increment. They plan, execute, and deliver increments during each Sprint.

Nexus-Specific Responsibilities: Development Teams collaborate with other teams to ensure that their increments can be integrated seamlessly. They communicate regularly in Nexus events to manage dependencies and align their work.

Stakeholders:

Responsibilities: Stakeholders are individuals or groups with an interest in the product being developed. They provide feedback and insights to ensure that the product meets user needs and business goals.

Nexus-Specific Responsibilities: Stakeholders participate in Nexus events such as Nexus Sprint Reviews to provide feedback on the integrated increment. Their insights contribute to the continuous improvement of the Nexus.
