1. What is Scrum? Fundamental Knowledge Before Changing Jobs

1. スクラム開発とは?転職前に知るべき基礎知識

We will concisely outline the basic structure of Scrum, which functions as a common language in the tech job market.

The Basic Structure of Scrum

Scrum is an iterative development framework that repeats short development cycles called “Sprints,” typically lasting 1 to 4 weeks. According to the official Scrum Guide, Scrum is defined as a “lightweight framework that helps people, teams, and organizations generate value through adaptive solutions for complex problems.”

Scrum follows a clear structure known as “3-5-3” (3 roles, 5 events, and 3 artifacts), which serves as a global standard during technical interviews.

The Three Roles:

  • Product Owner (PO): Responsible for maximizing the product’s value.
  • Scrum Master (SM): Ensures the team adheres to Scrum theory and practices while removing impediments.
  • Developers: The team members committed to creating any aspect of a usable Increment each Sprint.

The Five Events:

  • Sprint: The 1-4 week development cycle itself.
  • Sprint Planning: Setting the work to be performed in the Sprint.
  • Daily Scrum: A 15-minute daily meeting to inspect progress and adapt the plan.
  • Sprint Review: Inspecting the Sprint outcome and determining future adaptations.
  • Sprint Retrospective: Planning ways to increase quality and effectiveness.

The Three Artifacts:

  • Product Backlog: An emergent, ordered list of what is needed to improve the product.
  • Sprint Backlog: The set of Product Backlog items selected for the Sprint.
  • Increment: A concrete stepping stone toward the Product Goal.Source: Official Scrum Guide Definition

Relationship Between Agile and Scrum

Agile is a development philosophy that emphasizes four values: “Individuals and interactions,” “Working software,” “Customer collaboration,” and “Responding to change.”

Scrum, on the other hand, is a specific “framework” that puts these Agile values into practice. In job postings, “Agile experience” almost always refers to Scrum experience. According to a PwC Consulting survey, 90% of companies that achieved their expected DX results utilize Agile development, with Scrum being the primary method.

Why Scrum Experience is Currently the Focus of the Job Market

According to a 2024 IPA survey, approximately 20-40% of domestic companies have adopted Agile, including partial implementations. While Waterfall remains common, the adoption is particularly high among IT vendors, where nearly 40% have also introduced low-code/no-code tools.

Furthermore, research shows that 90% of successful DX companies leverage Agile to achieve “reduction of unnecessary development,” “flexible response to change requests,” and “faster time-to-market.” As business environments change rapidly, the demand for engineers who can navigate these shifts via Scrum is surging.

EVOLVING WITH AGILITY • 2026

As DX initiatives accelerate, we explain the background of why companies seek Scrum experience and the specific skills they evaluate.

Background of Corporate Hiring Trends

In the push for DX, companies face an urgent need to deliver value quickly. As business environments fluctuate due to customer trends, regulations, and supply chain risks, traditional Waterfall development struggles to keep pace.

The shift from legacy systems to modern development is another major factor. IPA reports that while half of user companies still carry legacy systems, about half are also moving toward in-house development. Agile expertise is essential for this transition.

With the growth of SaaS and startups, 80% of Agile-adopting companies report positive results, specifically citing “flexibility to requirement changes” (58.5%) as the top benefit.

Source: IPA “2024 Software Trend Survey Analysis Report”

Five Marketable Skills Gained Through Scrum

  1. Flexibility to Requirement Changes
    The ability to adjust priorities every 2-4 weeks based on feedback is indispensable in volatile markets.
  2. Short-Term Value Delivery
    Experience releasing functional products in short cycles aligns with MVP (Minimum Viable Product) and Lean Startup mindsets, making you “battle-ready” for new business ventures.
  3. Cross-functional Team Management
    Collaborative experience in self-organizing teams is a major strength for management roles. Servant leadership—supporting the team rather than just giving orders—is highly valued.
  4. Data-Driven Improvement Mindset
    Experience visualizing progress through Velocity or Burndown charts proves your ability to make objective, evidence-based decisions.
  5. Product-Oriented Development Thinking
    Prioritizing “user value” over “technical perfection” is a key requirement for moving into Product Manager or PO roles.

Differentiation from Waterfall Developers

The biggest differentiator is the ability to handle uncertainty. While Waterfall relies on strict adherence to a pre-defined plan, Scrum assumes change.

Release FrequencyLarge scale (months to a year)Small scale (every 2-4 weeks)

4. How to Choose the Right Workplace for Scrum Experience

4. スクラム開発経験を活かせる転職先の選び方

It is vital to distinguish between companies that “do” Scrum and those that just use the label.

How to Identify “Real” Scrum Practices

Avoid “Zombie Scrum” by asking these questions during interviews:

  • “How long is your Sprint, and why did you choose that length?” (Check for logic).
  • “How often do you hold Retrospectives?” (If not every Sprint, the culture of improvement is missing).
  • “Is the PO dedicated or juggling other roles?” (Part-time POs often cause bottlenecks).

Signs of “Fake” Scrum:

  • Daily Scrums are just status reports (they should be planning sessions for the next 24 hours).
  • Retrospectives happen, but no action items are implemented.
  • Sprint goals are frequently interrupted by “emergency” tasks.

Types of Companies Implementing Scrum

  • Growth Startups: High autonomy but often lack process maturity. Best for those who want to build both product and organization.
  • Mega-Ventures: Established frameworks and internal knowledge. Best for learning structured Scrum at scale.
  • DX Departments in Traditional Firms: Close to business goals but may face friction with legacy Waterfall culture. Best for those who want to be change agents.

Remote Work and Scrum

Scrum is highly compatible with remote work. Using tools like Miro, Slack, and Jira allows for high productivity without being in the office. Companies are increasingly hiring Scrum-experienced talent for remote positions because Sprint-based progress is easy to visualize and manage.

6. Standing Out in Interviews

6. スクラム開発経験者が面接で差をつけるポイント

Common Questions and Model Answers

“Tell us about a failure in Scrum and what you learned.”

  • Model: “I over-estimated team Velocity in a new project, leading to a missed Sprint Goal. During the Retrospective, we analyzed the root cause and introduced Planning Poker and a 20% buffer. Goal achievement improved to 90% in the following Sprints.”

“How do you handle conflict within the team?”

  • Model: “When split on architecture, I visualized the pros/cons based on business goals, technical skill, and cost. We agreed on a phased migration. This taught me the value of data-driven decision-making over emotional debate.”

Reverse Mentoring: Questions for the Company

  • “How is technical debt managed in the Product Backlog?”
  • “Do you have a culture of learning from failure? Can you give an example?”
  • “Is there a clear career path for Scrum Masters/POs here?”

MASTER THE ART OF SCRUM PIVOT • 2026

Roadmap for Beginners

  1. Read the Scrum Guide: It’s the “Source of Truth.” It’s less than 13 pages but requires multiple readings to grasp the depth.
  2. Get Certified: While not mandatory, CSM (Scrum Alliance) or PSM (Scrum.org) proves your commitment and foundational knowledge.
  3. Join Communities: Participate in events like Regional Scrum Gathering Tokyo or Slack groups to hear real-world stories.

How to Propose Scrum Internally

Start with a small Pilot Project (1 team, 2-3 months). Emphasize “risk reduction” and “faster feedback” to stakeholders. Even if it’s not a perfect implementation, “Leading a 3-month pilot” is a valid experience to put on your resume.

Gaining Experience via Side Gigs

Consider technical advisory roles for startups or contributing to Open Source Projects on GitHub that use Agile workflows. These real-world applications are highly regarded by recruiters.

9. Frequently Asked Questions (FAQ)

9.よくある質問(FAQ)
  1. Q: How many years of experience are needed?
    • A: 1 year (approx. 5-10 Sprints) is a good benchmark, but impact (Velocity/Release frequency) matters more than duration.
  2. Q: Can I transition from Waterfall?
    • A: Yes. Focus on your “potential” by getting certifications and showing a proactive learning mindset.
  3. Q: Is it possible to work remotely?
    • A: Absolutely. Scrum is highly compatible with digital tools, and many Scrum-heavy roles are 100% remote.
