Scrum is a responsive, efficient, and effective way of handling complex and ambiguous projects. More importantly, Scrum dives harmoniously with the values and principles laid out in the Manifesto for Agile Software Development.
Agile values and principles are the philosophical foundation for Agile methodologies, and Scrum aligns perfectly with these ideologies. It emphasizes customer collaboration, flexibility, individuals and interactions, and welcoming changes even late in development.
Agile Manifesto Values and How Scrum Aligns
- Individuals and interactions over processes and tools: While Scrum defines a set of roles and events, it strongly emphasizes individuals and their interactions. The focus on self-organizing teams allows individuals to decide collectively. Regular interactions, like daily Scrum meetings and retrospectives, provide a platform for continuous communication and negotiation among team members.
- Working software over comprehensive documentation: The primary outcome of every Scrum sprint is a potentially deliverable software increment, emphasizing working software. Scrum teams document as needed but do not let it stifle progress.
- Customer collaboration over contract negotiation: Scrum roles like the Product Owner and events like the Sprint Review involve the customer directly in the process, enabling a high level of collaboration.
- Responding to change over following a plan: The very structure of Scrum – short sprints, backlog grooming, sprint planning – incorporates and welcomes change. Course correction is an integral part of the process, not an exception.
Agile Manifesto Principles and How Scrum Aligns
- Satisfy the customer through early and continuous delivery of valuable software: The objective of each Scrum sprint is a potentially shippable application increment, allowing for constant delivery of value to the customer.
- Welcome changing requirements, even late in development: The Product Backlog is a living artifact, and changes are continually expected and incorporated. The Scrum team continuously refines and reprioritizes it to reflect the current understanding of the project.
- Deliver working software frequently: Scrum prescribes time-boxed iterations known as Sprints that conclude with a potentially shippable increment.
- Business people and developers must work together daily: The role of the Product Owner in Scrum ensures this principle is upheld.
- Build projects around motivated individuals and trust them: Scrum teams are self-organizing, vested with the power to make decisions that traditionally rested with project managers.
- Face-to-face conversation is the best form of communication: Daily Scrum and other Scrum events ensure face-to-face interactions.
- Working software is the primary measure of progress: Scrum emphasizes the importance of closing sprints with a potentially releasable functionality.
- Agile processes promote sustainable development: Scrum promotes sustainability by allowing the team to choose the amount of work they commit to for each sprint, enabling a consistent and maintainable pace.
- Continuous attention to technical excellence and good design: Scrum strongly ties to Extreme Programming principles like Test-Driven Development, Pair Programming, and Continuous Integration.
- Simplicity is essential: Scrum advocates for maximizing the amount of work not done, meaning that the team should always look for ways to simplify and improve the development process.
From these comparisons, it is clear that Scrum aligns with the Agile Principles and Values, making it an efficient and effective Agile framework. Students studying for the A-CSM (Advanced Certified ScrumMaster) exam should recognize and deeply understand this alignment to implement Agile and Scrum effectively.
