Agile vs Scrum: What is the difference?
If you are interested in project management, you may have heard of Agile and Scrum. These are two popular approaches to managing projects, especially in software development. But what exactly are they and how do they differ?
Agile is a philosophy of project management that emphasizes delivering value to customers through collaboration, communication, feedback, and adaptation. Agile is based on a set of values and principles guiding teams as they work together and deliver products or services.
Scrum is a specific framework for implementing Agile. Scrum defines roles, events, artifacts, and rules that help teams follow the Agile philosophy. Scrum teams work in short iterations called Sprints, where they plan, execute, review, and improve their work .
The main difference between Agile and Scrum is that Agile is a broad approach that can be applied to any project, while Scrum is a specific way of applying Agile to certain types of projects. There are also other frameworks that use Agile principles besides Scrum.
Agile at a High Level
Agile is a philosophy built on four core values and 12 principles as defined in the Agile Manifesto. These principles provide a foundation for empowering teams and building an engaging work environment.
The 4 Core Values of Agile
The core values of Agile identify areas in which we must place a greater focus on over traditional values. It does not mean the former replaces the latter, but it does mean that greater emphasis must be placed on the new way of thinking. The four core values of Agile are:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
The 12 Principles of Agile
The principles of Agile are a set of guidelines that promote an iterative, customer-focused approach to software development. These principles emphasize collaboration, flexibility, and continuous improvement throughout the development process.
- Customer satisfaction through early and continuous delivery of valuable software.
- Embrace changing requirements, even in late development stages.
- Deliver working software frequently, with a preference for shorter timescales.
- Collaborate with customers and stakeholders throughout the project.
- Build projects around motivated individuals and give them the support and trust they need.
- Use face-to-face communication whenever possible.
- Working software is the primary measure of progress.
- Maintain a sustainable pace of work for the team.
- Focus on technical excellence and good design to enhance agility.
- Keep things simple and maximize the amount of work not done.
- Allow self-organizing teams to make decisions and adjust to changing requirements.
- Regularly reflect on the team’s performance and adjust accordingly.
What is Scrum?
Scrum is an Agile framework for managing and completing complex projects. It is based on the principles of transparency, inspection, and adaptation, and emphasizes collaboration, flexibility, and continuous improvement. Scrum is structured around a series of short, time-boxed iterations called sprints, during which a cross-functional team works to deliver a potentially shippable product increment. The team is self-organizing and works together to complete the work, with a Scrum Master facilitating the process and removing any obstacles that arise. The Product Owner is responsible for prioritizing and managing the backlog of work, and works closely with the team to ensure the product is meeting the customer’s needs. Scrum provides a flexible and iterative approach to software development allowing teams to respond quickly to changing requirements and to deliver high-quality products on a regular basis.
Scrum at a High Level
Scrum can be summarized by 3-5-3-5. Scrum is built on 3 Roles, 5 Events, 3 Artifacts, and 5 Core values.
The 3 Roles
- Product Owner: Responsible for maximizing the value of the product and managing the product backlog.
- Scrum Master: Facilitates the Scrum process, ensures the team adheres to Scrum practices, and removes any impediments that the team may face.
- Developers: A self-organizing, cross-functional group of professionals responsible for delivering potentially releasable increments of the product at the end of each sprint.
The 5 Events
- Sprint Planning: A meeting where the team plans the work to be done during the upcoming sprint.
- Daily Scrum: A short, daily stand-up meeting for the team to synchronize their work and discuss any obstacles.
- Sprint Review: A meeting held at the end of each sprint to demonstrate the completed work to the stakeholders and gather feedback.
- Sprint Retrospective: A meeting for the team to reflect on the past sprint and identify areas for improvement.
- The Sprint: The final event is the Sprint itself. It is a fixed iteration length (from 1 – 4 weeks) that contains all of the other events.
The 3 Artifacts
- Product Backlog: A prioritized list of features, enhancements, and bug fixes that represent the desired functionality of the product.
- Sprint Backlog: A subset of the product backlog that the team has committed to delivering during a specific sprint.
- Product Increment: When work meets the team’s Definition of Done, a Product Increment is created. It is a potentially shippable unit of work that completely solves a customers problem.
The 5 Values
- Commitment: The team is dedicated to achieving the goals of the Sprint and delivering high-quality work.
- Focus: The team concentrates on the tasks at hand and prioritizes work according to the sprint goals.
- Openness: The team communicates honestly and transparently about their progress, challenges, and ideas.
- Respect: Team members treat each other with respect, valuing diverse perspectives and skills.
- Courage: The team faces challenges head-on and takes responsibility for their decisions and actions.
Some of the benefits of using Agile and Scrum are:
- They allow teams to respond quickly to changing customer needs and expectations
- They foster teamwork, transparency, and accountability among team members
- They improve quality and customer satisfaction by delivering frequent and valuable increments
- They encourage continuous learning and improvement by incorporating feedback loops
Some of the challenges of using Agile and Scrum are:
- They require a high level of commitment and discipline from team members
- They may not be suitable for projects that have fixed requirements or complex dependencies
- They may face resistance from stakeholders who are used to traditional methods of project management
In conclusion, Agile and Scrum are often mentioned together, but it is crucial to understand their differences. Agile is an overarching philosophy that encompasses a wide range of methodologies and principles that prioritize flexibility, collaboration, and customer satisfaction. Scrum, on the other hand, is a specific framework within the Agile umbrella that provides a structured approach to project management, complete with well-defined roles, ceremonies, artifacts, and values.
While Scrum is one of the most popular Agile methodologies, it may not be suitable for every project or organization. When choosing the right approach for your team, it’s essential to consider factors such as team size, project complexity, and organizational culture. By understanding the distinctions between Agile and Scrum, you can make more informed decisions about which approach will work best for your unique situation, ultimately leading to more successful projects and higher levels of customer satisfaction.
