What Is Scrum & Why It’s the Preferred Development Framework

Introduction

In today’s fast-paced digital economy, choosing the right software development methodology can make the difference between project success and failure. Businesses need frameworks that allow them to innovate quickly, adapt to changing requirements, and deliver high-quality products to market — without losing time or resources.

This urgent need for flexibility and speed is why Agile frameworks have become the gold standard for modern development teams. In fact, a staggering 94% of companies now practice Agile methodologies across their organizations.

Among the various software development frameworks available, one approach stands out for its simplicity, adaptability, and proven track record: the Scrum framework. According to recent research, 63% of organizations prefer Scrum at the team level, making it by far the most widely used Agile practice today.

The adoption of Agile has accelerated dramatically over the past few years. Agile adoption in software teams jumped from 37% in 2020 to 86% in 2021 (Source: Digital.ai), driven by the need for faster delivery cycles and more responsive development processes. Across industries, nearly 70% of IT and software development teams have embraced Agile, while a significant portion of engineering, product management, and R&D departments have followed suit.

Organizations clearly see the value in agility: 91% state that adopting Agile is a strategic priority (Source: KPMG). And among Agile teams, 81% report using some version of Scrum, whether it's classic Scrum, Scrumban, or a hybrid model (Source: Digital.ai).

While other Agile approaches like Extreme Programming (XP) and Lean are available, they have fallen out of favor in recent years, with only 1% of teams using each method (Source: Digital.ai). This further highlights Scrum’s dominance in the world of Agile and software development methodologies.

In this guide, we’ll explore:

• What exactly the Scrum framework is,
• Why it has become the preferred choice among Agile frameworks,
• How it compares to other software development frameworks,
• And when it’s the best fit for your software projects.
  

If you're looking to better understand the modern software development landscape — and how Scrum can empower your teams — this guide will give you everything you need to know.

What Is the Scrum Framework?

The Scrum framework is one of the most popular and effective software development methodologies used by modern teams to deliver complex projects quickly and efficiently. Rooted in the principles of Agile frameworks, Scrum emphasizes iterative progress, cross-functional collaboration, and continuous feedback.

At its core, Scrum is designed to help teams work together more effectively. Instead of attempting to plan and execute a large project all at once, Scrum breaks work into manageable pieces called sprints — typically short cycles of two to four weeks. After each sprint, teams review progress, adjust priorities, and plan the next steps, allowing them to remain flexible and responsive to change.

‍

The Origins of Scrum

The concept of the Scrum framework was formalized in the early 1990s by Ken Schwaber and Jeff Sutherland. Drawing inspiration from lean manufacturing principles, they introduced Scrum as a lightweight but powerful framework for managing complex software development projects.

The name "Scrum" itself is borrowed from rugby, where a scrum is a formation where players work together to move the ball forward. Similarly, Scrum in software development emphasizes teamwork, shared goals, and adaptive problem-solving.

In 1995, Schwaber and Sutherland presented Scrum formally at the OOPSLA (Object-Oriented Programming, Systems, Languages & Applications) conference, and the framework has been evolving ever since. Today, it stands as the dominant force among Agile frameworks, used by millions of teams worldwide.

‍

The Core Philosophy Behind Scrum

Unlike traditional software development methodologies that rely heavily on upfront planning and rigid execution, Scrum embraces complexity and unpredictability. Its core philosophy is based on three pillars:

• Transparency: All aspects of the process must be visible to those responsible for the outcome.
• Inspection: Scrum users must frequently inspect progress toward a sprint goal to detect undesirable variances.
• Adaptation: If deviations from goals are identified, the process must be adjusted as soon as possible.
  

By prioritizing flexibility and feedback loops, Scrum enables teams to quickly respond to changes in user needs, market conditions, or technological landscapes.

‍

Scrum’s Role in Agile Frameworks

Scrum is often seen as the practical embodiment of Agile principles. While Agile provides a broad philosophy of values and principles (outlined in the Agile Manifesto), Scrum offers a concrete, structured way to implement these values in day-to-day development work.

In fact, among teams practicing Agile today, 81% use some form of Scrum, whether through traditional Scrum, Scrumban (Scrum + Kanban hybrid), or customized models.

When organizations seek to adopt Agile frameworks, they most commonly turn to Scrum as the starting point because of its simplicity, scalability, and proven success across industries.

‍

What Makes Scrum Different From Other Software Development Frameworks?

Compared to other software development frameworks like Waterfall, Kanban, or Lean, Scrum’s distinctiveness lies in its:

• Iterative delivery: Work is done in short, repeatable cycles.
• Cross-functional teams: Teams contain all the expertise needed to deliver increments without depending on outsiders.
• Defined roles and ceremonies: Everyone has clear responsibilities, and work is structured around regular events like daily stand-ups, sprint reviews, and retrospectives.
• Continuous improvement: Teams inspect and adapt constantly, rather than waiting until the end of a project.

This combination of structure and flexibility makes Scrum an ideal choice for fast-paced, dynamic environments where adaptability and customer feedback are crucial.

‍

Core Components of the Scrum Framework

To fully understand the scrum framework, it’s essential to break down its core components. Scrum is built on clearly defined roles, artifacts, and events — each serving a specific purpose in driving project progress, enhancing collaboration, and maintaining transparency.

These components are designed to support the broader goals of Agile frameworks: responsiveness, continuous improvement, and delivering value early and often. By defining how people work together, what they work on, and how they organize that work, Scrum provides a structured yet flexible software development methodology that scales across industries and team sizes.

‍

1. Scrum Roles

Scrum teams are deliberately lean and cross-functional, typically composed of 10 or fewer members. Everyone on the team is expected to collaborate closely and contribute to delivering a usable product increment at the end of each sprint.

a. Product Owner

The product owner is responsible for maximizing the value of the product resulting from the team’s work. They own the product backlog—a dynamic, ordered list of features, fixes, and improvements — and are the voice of the customer.

They manage stakeholder expectations, define goals, and ensure the team is working on the highest-value items. The product owner has the final say on what gets prioritized and why.

‍

b. Scrum Master

The scrum master acts as a facilitator and coach, ensuring the team follows scrum practices and principles. They help remove obstacles, encourage team ownership, and promote a culture of continuous improvement.

Importantly, the scrum master is not a project manager. Their job isn’t to assign tasks but to empower the team to self-organize and self-manage.

‍

c. Development Team

This is a self-organizing group of professionals who do the actual work of building the product. The development team collectively owns the delivery of each sprint increment. Roles within the team (such as frontend developer, backend engineer, or QA) may vary, but as a unit, they are accountable for outcomes.

‍

2. Scrum Artifacts

Artifacts in Scrum are designed to provide transparency and key information about the project. They help all stakeholders maintain alignment and visibility into progress.

‍

a. Product Backlog

The product backlog is a living, evolving list of everything that might be needed in the product. It is owned and maintained by the product owner and represents the single source of truth for all work to be done.

The backlog is never complete; as the product evolves and feedback is gathered, new items are added, removed, or reprioritized.

‍

b. Sprint Backlog

The sprint backlog is a subset of the product backlog. It consists of the items the team commits to completing during a specific sprint. It’s created collaboratively during the sprint planning meeting and is updated daily as the team progresses.

‍

c. Increment

The increment is the sum of all completed work items at the end of a sprint. It must be usable and potentially shippable, even if the product owner chooses not to release it. Each increment builds on the previous one, steadily growing the product’s capabilities.

‍

3. Scrum Events (Ceremonies)

Scrum prescribes a series of time-boxed events that structure the team’s workflow. These Agile framework ceremonies ensure a rhythm of planning, execution, review, and improvement.

‍

a. Sprint

A sprint is a fixed-length event (usually 2–4 weeks) during which the Scrum team delivers a usable increment. All other scrum events take place within the sprint. Once a sprint begins, its duration is fixed, and scope changes are avoided.

‍

b. Sprint Planning

This marks the start of the sprint. The team discusses what can be delivered and how that work will be accomplished. The outcome is a clear sprint goal and a sprint backlog.

‍

c. Daily Scrum (Stand-up)

This is a short, 15-minute meeting held every day of the sprint. The team inspects progress toward the sprint goal and plans the next 24 hours. It fosters accountability and quick problem-solving.

‍

d. Sprint Review

Held at the end of the sprint, this event is an opportunity to inspect the increment and adapt the product backlog based on feedback. Stakeholders are invited to review what was built and offer input.

‍

e. Sprint Retrospective

This is the final event of the sprint. The team reflects on what went well, what didn’t, and how they can improve in the next sprint. The goal is to continuously evolve and become more effective.

‍

The Power of Simplicity and Structure

The true power of the Scrum framework lies in its balance of simplicity and structure. Its roles, artifacts, and events work together to minimize ambiguity, enhance collaboration, and ensure that progress is always visible.

Unlike heavyweight software development methodologies that rely on strict planning and documentation, Scrum empowers teams to focus on delivering real value—fast. It is this agility and clarity that has made Scrum the go-to choice for software development frameworks around the world.

‍

Why Scrum Is the Preferred Software Development Methodology

As organizations race to deliver high-quality digital products in increasingly dynamic environments, the demand for adaptable, collaborative, and efficient processes has skyrocketed. This is why Scrum has emerged as the most widely used software development methodology among Agile practices — and why it continues to grow in popularity across tech-driven teams.

While Agile as a whole has become a strategic priority for modern businesses (with 91% of organizations prioritizing Agile adoption, according to KPMG), the Scrum framework remains the top choice for implementing those Agile methodologies at scale.

So what makes Scrum so universally effective?

‍

1. Fast, Iterative Delivery for Rapid Results

In traditional development models like Waterfall, teams spend months (or even years) building a product before it ever reaches users. Scrum flips that model by emphasizing short sprints and continuous delivery, allowing teams to release usable increments in just 2–4 weeks.

This speed is invaluable in today’s tech landscape, where market demands and customer expectations evolve rapidly. By releasing frequently and gathering feedback early, Scrum teams can pivot quickly — a competitive advantage that slower software development frameworks simply can’t offer.

‍

2. Flexibility Without Chaos

Scrum is built to embrace change — not resist it. While other software development methodologies rely on rigid plans, Scrum acknowledges that customer needs often shift. Its iterative nature allows teams to make course corrections after each sprint, avoiding the sunk-cost trap of following outdated roadmaps.

And yet, this adaptability doesn't lead to disorder. Thanks to structured events like sprint planning and daily stand-ups, Scrum keeps the team focused and aligned, even as priorities shift.

‍

3. Transparency and Accountability at Every Level

One of Scrum’s greatest strengths lies in its emphasis on visibility. With defined roles, daily updates, sprint reviews, and retrospectives, every team member understands what’s happening, what’s expected, and how their work contributes to the sprint goal.

This level of transparency cultivates trust, eliminates confusion, and ensures accountability without micromanagement. Unlike some Agile frameworks that are lighter on structure, Scrum provides enough scaffolding to keep teams aligned — especially in remote or cross-functional environments.

‍

4. Stronger Collaboration and Empowered Teams

Scrum encourages open communication between team members, stakeholders, and customers. Through frequent feedback loops and a shared understanding of goals, everyone involved has a voice — not just senior decision-makers.

This collaborative spirit is crucial to innovation. When developers, designers, QA, and product owners work together daily, they’re more likely to catch issues early, brainstorm smarter solutions, and create better products overall.

Scrum also empowers teams to self-organize, promoting ownership and autonomy. This contrasts with traditional models where top-down management stifles creativity and slows progress.

‍

5. Continuous Improvement Through Retrospectives

Unlike some software development frameworks that view post-project review as an afterthought, Scrum bakes improvement directly into its process through the Sprint Retrospective.

Every few weeks, teams are encouraged to reflect on what went well, what didn’t, and how they can do better. This makes Scrum a powerful driver of team maturity, helping teams become more efficient, collaborative, and innovative with each sprint.

It’s no surprise that Agile teams using Scrum report higher morale, faster delivery times, and better end-user satisfaction across the board.

‍

6. It Scales — Without Losing Agility

One common misconception is that Scrum only works for small teams. In reality, frameworks like Scrum@Scale, LeSS (Large Scale Scrum), and SAFe (Scaled Agile Framework) allow organizations to extend Scrum principles across departments, even enterprises.

Whether you’re managing one team or ten, the core values of Scrum — transparency, inspection, and adaptation — scale effectively when implemented with discipline.

As companies increasingly move toward cross-functional collaboration across product, engineering, QA, and operations, Scrum remains one of the most scalable and sustainable options among software development frameworks.

‍

7. Proven Track Record Across Industries

Scrum is no longer just for software. Today, it’s used across industries — from finance and healthcare to education and manufacturing — to deliver better results, faster.

In IT and software development, however, Scrum continues to lead:

• 86% of software teams adopted Agile by 2021 (up from 37% in 2020)
• 81% of Agile teams use some version of Scrum
  
  

With such widespread success, it’s no wonder that Scrum is the default choice for companies looking to modernize their processes and outperform competitors.

‍

8. It’s Built for Human-Centric Product Development

Modern software isn’t just about clean code — it’s about building experiences users love. Scrum places customers at the center by promoting regular feedback, incremental releases, and constant prioritization of user value.

By focusing on real-world outcomes rather than vanity metrics, Scrum ensures that development isn’t just fast — it’s meaningful. Teams stay aligned with what matters most: solving real problems for real people.

Why Scrum Wins

In a world where speed, adaptability, and innovation define success, Scrum offers a framework that is lean, efficient, and deeply human-centric. It’s not just a software development methodology — it’s a mindset shift that empowers teams to do their best work continuously.

From startups to Fortune 500 companies, Scrum continues to be the preferred framework for Agile software development — and for good reason.

‍

Scrum vs Other Agile Frameworks

Agile is a mindset — not a single methodology. While the Agile Manifesto lays out core values and principles, there are several frameworks designed to implement Agile in practice. These include Scrum, Kanban, SAFe, Extreme Programming (XP), and Lean—each with its own structure, use cases, and strengths.

Scrum stands out as the most widely adopted and battle-tested among them. But, understanding the alternatives is key to recognizing why Scrum is often the preferred software development methodology for modern teams.

‍

Scrum vs Kanban

Kanban focuses on visualizing work and improving flow. Unlike Scrum’s time-boxed sprints, Kanban has a continuous delivery model with no set iterations. It uses a board to limit work in progress (WIP) and reduce bottlenecks.

While Kanban is great for operations teams and support-based workflows, it lacks the structured roles, events, and sprint planning found in the Scrum framework. For product-focused teams aiming to build complex software in stages, Scrum provides a more goal-oriented approach.

Scrum is better for iterative product development, while Kanban excels in continuous delivery environments.

‍

Scrum vs SAFe (Scaled Agile Framework)

SAFe is an enterprise-level Agile framework that extends Scrum principles across large organizations. It incorporates layers of coordination between multiple Scrum teams (called Agile Release Trains), along with strategic planning tools and business alignment features.

SAFe offers scale — but at the cost of complexity. It introduces additional roles, artifacts, and overhead that smaller teams may find burdensome.

Scrum is more lightweight and accessible, while SAFe is best for large enterprises managing multiple cross-functional teams.

‍

Scrum vs Extreme Programming (XP)

XP emphasizes engineering practices like test-driven development (TDD), pair programming, and continuous integration. It’s highly technical and focuses on software quality at the code level.

While XP and Scrum share values like collaboration and feedback, Scrum offers a broader organizational framework, including product ownership, backlog management, and sprint planning.

Interestingly, XP has largely faded from mainstream use — with only 1% of teams using it in 2021.

Scrum is broader and more team-structure focused, whereas XP is more about engineering discipline.

‍

Scrum vs Lean

Lean originates from manufacturing (specifically Toyota) and focuses on eliminating waste and maximizing customer value. It emphasizes continuous improvement (Kaizen), flow efficiency, and reducing cycle time.

Lean’s principles align with Agile values, but as a standalone software methodology, it lacks Scrum’s clearly defined roles and ceremonies.

Scrum provides structure, Lean provides philosophy — and the two are often used together.

‍

Scrum: A Framework That Balances Structure and Flexibility

What truly sets Scrum apart from other Agile frameworks is its balance between predictability and adaptability. It offers just enough structure to create accountability and repeatable success — without becoming overly rigid.

And the results speak for themselves:

• Teams practicing full Scrum report 250% better quality than teams that don’t use estimation practices (Source: CA Technologies).
• 78% of Scrum practitioners would recommend it to friends and colleagues (Source: Scrum Alliance).
• 70% of agile organizations say it helps them go to market faster, a key differentiator in fast-moving industries (Source: JCURV).
  

While other software development frameworks may suit certain use cases or company sizes, Scrum continues to dominate because it is:

• Simple to understand, but powerful in execution
• Scalable from startups to enterprises
• Equally effective for co-located or remote teams

This is why Scrum remains the default framework for product, engineering, and design teams embracing Agile values.

‍

When to Use Scrum in Software Development

While the Scrum framework has proven highly effective for a wide range of teams and industries, it’s not a one-size-fits-all solution. Like any software development methodology, Scrum works best in environments that align with its principles of flexibility, collaboration, and iterative delivery.

So how do you know when Scrum is the right fit for your team or project?

‍

Ideal Conditions for Using Scrum

Scrum shines in situations where:

‍

The Project Scope Is Complex or Evolving

If your requirements are likely to shift — whether due to changing market demands, user feedback, or stakeholder priorities — Scrum allows your team to adapt quickly through sprint cycles and backlog reprioritization.

‍

Cross-Functional Teams Are in Place

Scrum thrives when teams include all necessary roles (e.g., design, development, QA) to deliver a working increment without handoffs or silos. This enables faster delivery and tighter collaboration.

‍

Customer Feedback Is Valuable (and Accessible)

Scrum is built around constant feedback loops. If you have access to real users or stakeholders who can review deliverables regularly, you'll maximize Scrum’s iterative model.

‍

Time-to-Market Is Critical

In fast-moving industries — like fintech, SaaS, eCommerce, or healthtech — Scrum helps teams go from idea to execution in a matter of weeks, not months. In fact, 70% of Agile organizations say that Agile helps them achieve faster time to market (Source: JCURV).

‍

Examples of Projects Well-Suited for Scrum

• Software product development where user feedback is essential
• Startup MVPs that need rapid validation
• Feature releases within existing products
• Custom software development engagements with flexible scopes
• Remote or hybrid teams need clear structure and rhythm
  

In each of these cases, Scrum provides structure without stifling innovation — a crucial balance in today’s digital-first world.

‍

When Scrum Might Not Be the Best Fit

Despite its strengths, Scrum may not be ideal for every situation. Here are a few examples of when other software development frameworks might be a better option:

‍

Projects with Fixed Scope and Budget

If your project has tightly defined deliverables and little room for change — such as government contracts or formal RFPs — the Waterfall model may be more appropriate. Scrum is optimized for change, not rigidity.

‍

Teams Without a Product Owner or Agile Champion

Scrum depends on empowered roles. Without a dedicated product owner and a supportive Scrum master, teams may struggle with unclear priorities, unproductive retrospectives, or stakeholder misalignment.

‍

Projects That Are Maintenance-Focused

For projects involving routine bug fixes, small updates, or system support — especially across multiple products — Kanban may offer more flexibility and less ceremony than Scrum.

‍

Teams With No Access to Stakeholder Feedback

Scrum requires regular feedback loops to be effective. If stakeholders are unavailable or non-responsive, your team may find it difficult to align sprint goals with real-world needs.

‍

Choosing the Right Tool for the Job

Ultimately, selecting the right software development methodology comes down to understanding your project’s needs, your team’s structure, and your organization’s culture.

Scrum is often the best choice when:

• Speed matters
• Customer needs evolve rapidly
• Team collaboration is high
• Innovation is a core goal
  
  

But remember — the goal of Agile isn’t to force a framework but to deliver value early, often, and sustainably. For some teams, a hybrid approach (e.g., Scrumban) may be the most effective way to blend Scrum’s structure with Kanban’s flow.

If you’re unsure where to start, Scrum is a safe and scalable entry point into Agile that has helped thousands of organizations evolve their digital capabilities. As highlighted earlier, teams doing full Scrum report 250% better quality outcomes, and Scrum practitioners overwhelmingly recommend it, with 78% saying they’d endorse it to peers (Sources: CA Technologies & Scrum Alliance).

‍

Conclusion

In a landscape where innovation cycles are accelerating and customer expectations are constantly evolving, the pressure is on for organizations to deliver faster, better, and smarter. That’s exactly why the Scrum framework has become the preferred choice for so many teams looking to adopt a modern, flexible, and results-driven software development methodology.

Scrum offers a practical, scalable way to apply the principles of Agile frameworks — empowering cross-functional teams to self-organize, work in short iterative cycles, and continuously deliver value. With defined roles, clear goals, and regular feedback loops, Scrum helps minimize waste, reduce risk, and improve collaboration across every level of the development process.

And the results are clear:

• Teams practicing full Scrum report 250% better product quality
• 70% of Agile organizations say it helps accelerate time to market
• 78% of Scrum users would recommend it to their peers
• Companies that invest in building an Agile culture — often powered by Scrum — report up to a 237% increase in commercial performance (Source: JCURV)
  

In a world saturated with development frameworks and methodologies, Scrum stands out by striking a rare balance: it’s structured enough to bring clarity, yet flexible enough to adapt to change. It works just as well for startups launching MVPs as it does for enterprises scaling complex platforms across multiple teams.

As the future of software development continues to evolve — toward faster cycles, more collaborative teams, and user-first thinking — Scrum is well-positioned to remain a pillar of success.
