Overview of Scrum

Note that I used terms customers and end-users interchangeably, as well as product and service to mean the same thing.

What is Scrum?

Scrum is a framework for project management, primarily used in software development. It applies agile principles to meet user needs quickly and cost-effectively. As technology evolves, including the rise of Generative AI, Scrum's ability to deliver value rapidly becomes even more crucial. Scrum achieves this through specific team-based activities and defined roles for team members.

Let's break it down into a quick high-level overview:

3 team member roles

• Scrum Master
• Product Owner
• Team member

5 events

• Sprint Planning
• Sprint
• Daily Scrum
• Sprint Review
• Sprint Retrospective

3 artifacts

• Product Backlog
• Sprint Backlog
• Product Increment

Values

Let's cover the philosophical elements in Scrum.

Scrum is built on five core values that guide team behavior and decision-making. These values are:

• Commitment: Team members commit to achieving their goals and supporting each other.
• Focus: Everyone concentrates on the work of the Sprint and the overall goals of the project.
• Openness: The team and stakeholders agree to be transparent about work and challenges.
• Respect: Team members respect each other's abilities and independence.
• Courage: Team members have the courage to do the right thing and work on tough problems.

These values are essential for creating a collaborative and effective Scrum team. They foster trust, enable creative solutions, and help teams navigate complex projects.

Empiricism

Scrum is rooted in empiricism, which means making decisions based on what is observed. This empirical approach is founded on three pillars:

Transparency

Important aspects of the process must be visible to those responsible for the outcome. In Scrum this includes:

• Product Backlog: The list of features, requirements, and improvements should be visible to all team members and stakeholders. This allows everyone to see what work is planned and how it's prioritized.
• Sprint Backlog: The tasks selected for the current Sprint should be transparent to the entire Scrum Team. This includes what work is in progress, completed, or yet to be started.
• Definition of Done: The criteria that determine when a work item is considered complete should be clear to everyone involved in the project.
• Sprint Goals: The objective of each Sprint should be communicated and understood by all team members and relevant stakeholders.
• Impediments: Any obstacles or issues hindering the team's progress should be openly discussed and made visible, typically during the Daily Scrum.
• Team Capacity: The team's availability and workload should be transparent to help with realistic Sprint Planning.
• Progress Tracking: Visual aids like burndown charts or sprint boards should be accessible to show real-time progress towards Sprint goals.

This level of transparency ensures that all team members and stakeholders have a shared understanding of the project's status, challenges, and goals. It fosters trust, enables informed decision-making, and allows for timely adjustments when needed.

Inspection

The team should frequently inspect Scrum artifacts and progress toward goals to detect undesirable variances. This includes:

• Product Backlog: Regularly refined by the Product Owner, often with input from the Development Team.
• Sprint Backlog: Reviewed daily during the Daily Scrum meeting.
• Product Increment: Examined during the Sprint Review.
• Team processes: Evaluated in the Sprint Retrospective.

These inspections happen throughout the Sprint cycle:

• Daily Scrum: Team members inspect progress toward the Sprint Goal.
• Sprint Review: Stakeholders and the Scrum Team inspect the outcome of the Sprint.
• Sprint Retrospective: The Scrum Team inspects its processes and interactions.

Inspection is crucial for transparency and adaptation. It allows the team to identify issues early, learn from experience, and continuously improve their work and processes.

Adaptation

If an inspection reveals that one or more aspects of the process deviate outside acceptable limits, adjustments must be made as quickly as possible. Adaptation in Scrum occurs in several ways:

• Sprint Planning: The team adapts its plan based on the current Product Backlog and lessons from previous Sprints.
• Daily Scrum: Team members adapt their daily plans to optimize progress towards the Sprint Goal.
• Sprint Review: The Product Backlog is adjusted based on feedback and new insights.
• Sprint Retrospective: The team identifies improvements to their processes and creates a plan to implement them.

Adaptation ensures the team remains agile, continuously improving their processes, product, and overall effectiveness. It allows Scrum Teams to respond quickly to changes in requirements, technology, or market conditions, maintaining their competitive edge.

The three pillars of Transparency, Inspection, and Adaptation enable teams to respond quickly to changes and continuously improve their processes and products.

Flexibility of the Scrum Framework

While it's crucial to implement all elements of Scrum for it to work effectively, it's worth noting that Scrum is designed to be flexible and adaptable to different contexts. Teams can adjust certain aspects, such as Sprint length or estimation techniques, to better fit their specific needs and working environment.

However, it's important to maintain the core Scrum framework. Any adaptations should be made thoughtfully and with the agreement of the entire Scrum Team, ensuring they don't compromise the fundamental principles of Scrum.

If an organization attempts to implement Scrum without all of the above 3 roles, 5 events, and 3 artifacts, then it is not Scrum.

If your org wants to see if Scrum can work then you must implement it in full to give it the best chance of helping your teams to succeed. Every aspect of Scrum outlined above is tightly interwoven to support other aspects. The Sprint Retrospective aims to enhance work processes, ultimately improving Sprint outcomes and the products showcased in Sprint Reviews.

Only after Scrum has been used by your teams and you know for sure it isn't work, should you attempt to add other agile concepts, such as Kanban on top of the Scrum processes.

Roles

Now let's go over roles, events, and artifacts in more detail.

Scrum Master

The Scrum Master can be thought of as the project manager, but not exactly. They act as a coach and servant leader, guiding the team in applying Scrum principles to optimize productivity and value delivery.

They run meetings, remove obstacles blocking team progress, and coach the team members on ways to make Scrum work for them.

Product Owner

The Product Owner is the voice of the customer in regards to the product or service being developed. They are the bridge between the business needs and the customer needs, helping the development team to understand and balance both needs. Their primary responsibility is to create a prioritized backlog of features that customers want.

Team Member

A Team Member is anyone on the team who produces code, content, or other material that improves the product or service being developed. They self-organize together to determine how and what get's done. It's a refreshing approach in that a project manager isn't dictating what work gets done, and no one is micromanaging them on the how it gets done.

Team Members look at the product backlog the Product Owner created and take the prioritization seriously, but if needed will pull backlog features lower on the priority list. These backlog features are what they work on for the current sprint.

Events

Now that I've mentioned Sprint, let's discuss that and the other events in more detail.

Sprint

All of the work that the team members do happens within a time-box. A time-box is 1-4 weeks where the team will work on a selected number of features that improve the product or service for end-users. Other events, such as the Daily Scrum, Sprint Review, and Sprint Retrospective also occur during a Sprint.

Sprint Planning

But before the Sprint can start, the team members, Product Owner, and Scrum Master will meet to discuss what should be worked on during the upcoming Sprint.

The Scrum Master leads and facilitates the discussion, making sure the meeting runs efficiently, and is productive. There are several approaches Scrum Masters can use to help the team estimate the amount of work involved for each feature

• Planning Poker (aka Scrum Poker)
• T-Shirt Sizing
• Dot Voting
• The Bucket System
• Affinity Mapping

Explaining each of the above is out of the scope of this quick overview guide, but in a future article I'll go over how to use each one.

The Product Owner comes prepared with the prioritized backlog of features they know customers and the business would like in the next release of the product. They will answer questions team members have about the customer and business needs.

Team members will discuss each feature from the backlog and scope out the work involved. They will decide how much work they can accomplish in a given Sprint, which typically lasts 1-4 weeks. Sprints do not change in length after the team has decided how long their sprints are. This means they have to think critically about what is feasible to accomplish within the given time constraint.

At the end of the Sprint Planning meeting, the team knows exactly which features will be worked on for the next Sprint.

Daily Scrum

Once the Sprint starts, each day the team will meet in what's called the Daily Scrum. These meetings need to be quick, and too the point. Everyone stands in a circle and says:

• What they worked on yesterday
• What they are working on today
• Any issues that are blocking them from progressing

Nothing more, nothing less. This meeting format is designed to share essential information quickly. It's important not to get bogged down in the details during these meetings. That can be hashed out afterward.

As an example, I was running a Daily Scrum meeting at LucasArts and an engineer said they were blocked because they were unsure how to approach solving a problem. Another engineer in the circle started asking them questions to help solve the issue. I knew this would quickly derail the flow of the meeting and apologized for interrupting, thanked them for wanting to help, and reminded them that it's best to do that after the meeting. I let them know the meeting will end in a few minutes, and they can talk about the issue in more detail. That flow of information and collaboration is exactly what the Daily Scrum meeting encourages. That way, other people in the meeting are not held up by conversations that don't involve them.

The entire team, including the Product Owner, should attend this meeting. The Scrum Master's presence is crucial as they facilitate the session.

Sprint Review

When time is up during the Sprint, it's time to show off what the team completed in the Sprint Review session. Everyone attends, including some organizational stakeholders if appropriate, and maybe even end-users if that is helpful.

Ideally, the product shown is potentially shippable to end-users, but if it's not usable during the Sprint Review, it means the team selected too much work to accomplish. Next Sprint they'll need to select a smaller amount of work so that they have something to demonstrate as working in the Sprint Review. Note that working is not the same as complete. The team must be OK with reviewing an unfinished product. It's not about perfection, but it is about seeing what progress was made during the Sprint, which features are on the right track, and which need some more work.

Sprint Retrospective

In this meeting, the team comes together to discuss how to improve the ways in which work gets done. Are the meetings effective, is the backlog communicating the right information, was the Sprint Review helpful in demonstrating the progress and value of the product and service? In other words, a Sprint Retrospective is a meeting where the team reflects on their process and identifies opportunities for improvement. Two approaches that Scrum Masters can use include:

• The "Start, Stop, Continue" format: where team members identify things they want to start doing, stop doing, and continue doing.
• The "Rose, Thorn, Bud" format: where team members identify things that went well (rose), things that didn't go well (thorn), and things that have potential for growth (bud).

Artifacts

Now let's discuss the 3 different Scrum artifacts a team produces. These artifacts help teams organize work, maintain transparency, and deliver value incrementally in short cycles.

Product Backlog

This is a prioritized list of all desired features, improvements, and fixes for the product. It's like a dynamic to-do list that evolves as the project progresses. It's continuously refined as more is learned about the product and its users.

Sprint Backlog

A subset of items pulled from the Product Backlog that the team commits to complete during the current sprint. Remember, a sprint is a short fixed period of work, typically 1-4 weeks. The Sprint Backlog is the team's immediate action plan.

Product Increment

This is the sum of all completed items from the Sprint Backlog at the end of a sprint. It represents a potentially shippable version of the product with new features or improvements added.

Product Goal

While working on a Product Increment, it's crucial the team has a shared vision of what they are working towards.

The Product Goal is a crucial concept introduced in the 2020 Scrum Guide update. It describes a future state of the product which can serve as a target for the Scrum Team to plan against. The Product Goal is the long-term objective for the Scrum Team and is included in the Product Backlog.

Having a clear Product Goal helps the team maintain focus and ensures that all work contributes to a coherent vision for the product. The Product Owner is responsible for developing and explicitly communicating the Product Goal.

Definition of Done

The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.

When a Product Backlog item meets the Definition of Done, an Increment is born. This shared understanding creates transparency and helps the Scrum Team know when work is complete on an Increment of the product.

The entire Scrum Team must agree on and commit to the Definition of Done. It's used to assess when work is complete on the product Increment and helps ensure quality. If multiple Scrum Teams are working together on a product, they must mutually agree on and commit to the same Definition of Done.

Embracing Scrum for Agile Success in the AI Era

As we've explored throughout this overview, Scrum is more than just a project management framework—it's a philosophy that empowers teams to deliver value iteratively and adapt to changing requirements with agility. By embracing the roles, events, artifacts, and principles of Scrum, organizations can foster a culture of continuous improvement and customer-centric development.

Key Takeaways:

1. Scrum's foundation lies in its three pillars: transparency, inspection, and adaptation.
2. The framework is built on five core values: commitment, focus, openness, respect, and courage.
3. Specific roles (Scrum Master, Product Owner, Team Members) work together to ensure project success.
4. Regular events like Sprint Planning, Daily Scrums, and Sprint Reviews keep the team aligned and productive.
5. Artifacts such as the Product Backlog and Sprint Backlog help maintain transparency and guide the team's efforts.

Implementing Scrum effectively requires commitment and practice, but the benefits—increased productivity, higher quality products, and improved team morale—make it a worthwhile investment for any organization aiming to thrive in today's fast-paced business environment.

Moreover, with the rapid rise of AI tools in product development and other industries, the pace of change is accelerating at an unprecedented rate. These AI-driven advancements are not just transforming how we build products, but also how quickly we can iterate and improve upon them. In this new landscape, agile methodologies like Scrum are becoming more crucial than ever. The ability to adapt quickly, pivot when necessary, and continuously deliver value to customers is no longer just an advantage—it's a necessity for survival and success in the AI-augmented world of product development.

As a passionate advocate for Scrum methodologies, I believe that its principles can transform not just how we work, but how we approach challenges and innovation in any field, especially as we navigate the exciting and sometimes unpredictable waters of AI-enhanced development. Whether you're new to Scrum or looking to refine your existing processes, remember that the journey to agility is ongoing. Embrace the framework, stay curious, and never stop learning—that's the true spirit of Scrum, and it's what will keep us at the forefront of innovation in this rapidly evolving technological landscape.
