Part 1: Introduction to Agile - Values, Principles, and Mindset
Part of the Agile Development 101 Series
My First Encounter with Agile
When I first heard about "Agile," I thought it was just another corporate buzzword. I'd been working with traditional project management approaches, and honestly, I was skeptical. "How can you build software without detailed upfront planning?" I wondered.
My perspective changed when I joined a team that practiced agile development. Instead of spending weeks writing specifications that would become outdated before development even started, we were shipping working features every two weeks. Instead of lengthy email chains about requirements, we had quick conversations with stakeholders. The difference was transformative.
In this article, I'll share what agile really means, the core values and principles that guide it, and why it's become the dominant approach in modern software development.
What is Agile?
Agile is not a methodology, tool, or framework - it's a mindset and set of values for software development. At its core, agile emphasizes:
Iterative development: Building software in small increments
Continuous feedback: Learning and adapting based on real usage
Collaboration: Working closely with stakeholders and team members
Flexibility: Responding to change rather than following a fixed plan
Think of it like navigating using GPS versus following printed directions. Printed directions might get you there if nothing changes, but GPS adapts in real-time to traffic, road closures, and new information.
The Agile Manifesto
In 2001, seventeen software developers gathered in Utah and created the Agile Manifesto. It contains four core values and twelve principles that guide agile software development.
The Four Values
Here's how I interpret these values based on my experience:
1. Individuals and Interactions Over Processes and Tools
What this means in practice:
Early in my career, I worked on a project where we spent more time updating Jira tickets than actually coding. We had elaborate workflows with 15 different statuses, mandatory fields for everything, and approval gates at every step. The process became the focus, not the product.
When I moved to an agile team, we still used Jira, but differently. We kept our board simple - "To Do," "In Progress," "Review," and "Done." We valued face-to-face conversations over detailed ticket descriptions. If something was unclear, we'd walk over to the product owner's desk (or hop on a quick call when remote) rather than going back and forth in comments.
Key insight: Tools like Jira and Confluence are valuable, but they should facilitate communication, not replace it.
2. Working Software Over Comprehensive Documentation
What this means in practice:
In one project, I spent two weeks writing a 50-page technical specification document. By the time development started, the requirements had changed, and half the document was obsolete. The team rarely referred to it.
In my agile projects, we focus on:
Working code that demonstrates functionality
Clear README files with setup instructions
API documentation generated from code (like Swagger)
Architecture decision records (ADRs) for important choices
We still document, but we ask: "What documentation would actually help someone understand or maintain this code?" Not "What documentation does the process require?"
Key insight: Documentation is important, but it should serve the software, not the other way around.
3. Customer Collaboration Over Contract Negotiation
What this means in practice:
I once worked on a project where we had a detailed contract specifying every feature, timeline, and deliverable. Six months in, the client's business priorities shifted dramatically. But we were locked into delivering features they no longer needed because "it was in the contract."
In agile teams, I've experienced a different approach. We maintain ongoing conversations with stakeholders:
Regular sprint reviews to demonstrate progress
Quick feedback loops to validate assumptions
Flexibility to reprioritize based on business value
This doesn't mean no contracts or agreements, but those agreements acknowledge that we'll learn and adapt together.
Key insight: The best outcomes come from partnership, not adversarial relationships.
4. Responding to Change Over Following a Plan
What this means in practice:
My first project as a developer had a detailed year-long plan. Three months in, a competitor launched a feature that threatened our business. But changing our plan meant "scope creep" and delay. We stuck to the plan and delivered on time - a product that was already outdated.
Agile doesn't mean no planning. I plan every sprint carefully. But I also know that:
User feedback might reveal better solutions
Business priorities can shift
Technical discoveries might change our approach
We plan, but we also build in flexibility to adapt.
Key insight: Change isn't a problem to prevent; it's information to incorporate.
The 12 Agile Principles
Let me break down the twelve principles with examples from my experience:
1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software
In my projects, I aim for:
Deploying features every sprint (typically 2 weeks)
Getting feedback from real users, not waiting for "perfect"
Releasing MVPs (Minimum Viable Products) to validate assumptions
Example: When building a reporting feature, instead of spending months on 20 different report types, we released 3 core reports in two weeks. User feedback revealed that only 1 of those reports was actually useful, but they needed 2 different reports we hadn't considered. We adapted quickly.
2. Welcome changing requirements, even late in development
This was hard for me at first. I'd think, "We already planned this sprint!" But I learned that:
Late changes often come from valuable learning
Flexibility is a competitive advantage
The cost of building the wrong thing is higher than the cost of changing plans
Example: Two days before a sprint ended, our product owner learned that a regulation changed. The feature we'd been building was now compliant but useless. We pivoted, shelved that work, and started on what actually mattered.
3. Deliver working software frequently, with preference for shorter timescales
My preference:
2-week sprints for most projects
Weekly deployments to staging
Continuous deployment to production when possible
Example: I use GitHub Actions to automatically deploy to staging on every merge to the main branch. This means stakeholders can see progress daily, not just at sprint reviews.
4. Business people and developers must work together daily
In effective agile teams, I've experienced:
Product owners attending daily standups
Developers participating in customer calls
Slack channels where everyone (tech and business) collaborates
Example: In my current setup, our product owner has desk space with the dev team. When questions arise, we get immediate clarification. No waiting for the next scheduled meeting.
5. Build projects around motivated individuals and trust them
Agile works best when:
Team members are empowered to make decisions
Management trusts the team's expertise
Individuals have autonomy in how they accomplish goals
Example: When tasked with building an authentication system, my team had the freedom to choose between implementing JWT ourselves or using a managed service like Auth0. We chose Auth0 based on our analysis, and management trusted our decision.
6. The most efficient method of conveying information is face-to-face conversation
Even as someone who uses ChatGPT and Copilot extensively, I've found:
A 5-minute conversation can resolve what would take 20 emails
Video calls are effective for remote teams
Pair programming sessions transfer knowledge faster than documentation
Example: When debugging a complex issue, instead of leaving detailed Jira comments, I'll schedule a quick screen-share session. We solve it in 15 minutes versus hours of async back-and-forth.
7. Working software is the primary measure of progress
I track progress by:
Features deployed to production, not story points completed
User adoption metrics, not lines of code written
Business value delivered, not hours logged
Example: In sprint reviews, I demo working features in staging or production. I don't present slide decks about progress; I show functional software.
8. Sustainable pace - teams should maintain a constant pace indefinitely
I've learned the hard way that:
Crunch time leads to burnout and bugs
Overtime is a sign of poor planning, not commitment
Sustainable pace yields better long-term results
Example: When a deadline approached and we weren't done, I advocated for cutting scope rather than working weekends. We delivered fewer features but maintained quality and team morale.
9. Continuous attention to technical excellence and good design
Agile isn't an excuse for sloppy code. I prioritize:
Code reviews on every pull request
Automated testing (unit, integration, end-to-end)
Refactoring as part of regular development
Technical debt addressed in every sprint
Example: We allocate 20% of each sprint to technical improvements. This might be adding tests, improving documentation, or refactoring legacy code. It's not "extra" - it's essential.
10. Simplicity - maximizing the amount of work not done
This principle has saved me countless hours:
Build what's needed now, not what might be needed later
YAGNI (You Aren't Gonna Need It) is real
Simple solutions are easier to maintain
Example: I was tempted to build a configurable notification system supporting email, SMS, Slack, and webhooks. We only needed email. I built just email, and we never needed the others.
11. Self-organizing teams produce the best architectures and designs
In effective agile teams:
The team collectively decides how to accomplish work
Technical decisions come from those closest to the code
Architecture emerges from collaboration, not decree
Example: When planning a microservices architecture, we didn't have an architect hand down a design. The dev team worked together, discussing trade-offs, and collectively designed the system.
12. Regular reflection and adaptation
This is where retrospectives shine:
What went well?
What could be better?
What will we change?
Example: After every sprint, my team has a retrospective. We've identified process improvements like better estimation techniques, clearer acceptance criteria, and more effective standup formats.
The Agile Mindset
Beyond values and principles, agile requires a mindset shift:
Embrace Uncertainty
Traditional approach: "We must know everything upfront" Agile approach: "We'll learn as we go"
I've learned to be comfortable saying "I don't know yet" and building in opportunities to learn.
Focus on Outcomes, Not Outputs
Traditional approach: "We delivered all the features" Agile approach: "We solved the customer's problem"
I measure success by impact, not activity.
Fail Fast, Learn Faster
Traditional approach: "Failure is not an option" Agile approach: "Early failures are learning opportunities"
When an experiment fails in sprint 2, it's valuable feedback. When a project fails after 6 months, it's a disaster.
Continuous Improvement
Traditional approach: "If it works, don't touch it" Agile approach: "Good can always be better"
I regularly ask: "How can we improve our process? Our code? Our product?"
Why Agile Matters
Having worked both ways, here's why agile resonates with me:
1. Faster Time to Market
Instead of waiting 6 months for a "complete" product, I ship valuable increments every 2 weeks. Early releases generate revenue, gather feedback, and validate assumptions.
2. Reduced Risk
Building in small increments means:
Smaller investments before validation
Earlier detection of problems
More opportunities to pivot
3. Better Product-Market Fit
Continuous feedback loops mean:
Building what users actually need
Adapting to market changes
Staying relevant
4. Higher Team Morale
In my experience, agile teams are happier because:
They see their work in production regularly
They have autonomy and ownership
They're not stuck on irrelevant work
5. Improved Collaboration
Agile breaks down silos between:
Business and technology
Developers and operations
Team members and stakeholders
Common Misconceptions About Agile
Let me address some myths I've encountered:
Myth 1: "Agile means no planning"
Reality: Agile involves constant planning. We plan sprints, releases, and backlogs. We just plan incrementally instead of all upfront.
Myth 2: "Agile means no documentation"
Reality: We document what's valuable. I maintain README files, API docs, and architecture decision records. I just don't write 100-page specs that nobody reads.
Myth 3: "Agile is just for software"
Reality: While born in software development, I've seen agile principles applied to marketing campaigns, hardware development, and business operations.
Myth 4: "Agile means working without structure"
Reality: Agile frameworks like Scrum provide clear structure - roles, ceremonies, and artifacts. It's disciplined flexibility.
Myth 5: "Agile is always better"
Reality: Agile works best when requirements are uncertain and feedback is available. For some projects (like building a bridge or medical device with strict regulatory requirements), traditional approaches might be more appropriate.
Agile vs. Waterfall
Having worked with both, here's my perspective:
When Waterfall Works Better
Requirements are well-understood and stable
Regulatory compliance demands extensive upfront documentation
Changes are prohibitively expensive (e.g., hardware manufacturing)
Team is distributed with limited ability to collaborate
When Agile Works Better
Requirements are unclear or likely to change
User feedback can guide development
Technology choices are flexible
Team can collaborate effectively
In reality, I've found that most modern software projects benefit from agile approaches.
Getting Started with Agile
If you're new to agile, here's what I recommend:
1. Start Small
Don't try to transform your entire organization overnight. Start with:
One team
One project
Simple practices
2. Focus on Principles, Not Process
Don't obsess over "doing Scrum perfectly." Understand the principles and adapt practices to your context.
3. Use Tools That Enable, Not Constrain
Tools like Jira, GitHub Projects, and Confluence can help, but don't let them dictate your process.
4. Get Training and Coaching
Consider:
Scrum.org or Scrum Alliance certifications
Agile coaching for your team
Books like "Scrum: The Art of Doing Twice the Work in Half the Time"
5. Embrace Experimentation
Try different practices:
Daily standups
Sprint retrospectives
User story mapping
See what works for your team and context.
My Agile Journey So Far
Agile isn't a destination; it's a journey of continuous improvement. I've experienced:
The Good:
Shipping valuable features every sprint
Building products users actually want
Working with energized, empowered teams
The Challenges:
Getting stakeholders comfortable with uncertainty
Maintaining discipline in retrospectives and planning
Balancing speed with technical excellence
The Lessons:
Start with principles, not practices
Adapt agile to your context
Focus on outcomes, not ceremonies
Continuous improvement is the real goal
Conclusion
Agile transformed how I approach software development. It's not about following a specific framework perfectly - it's about embracing values and principles that lead to better products, happier teams, and more satisfied customers.
The Agile Manifesto provides the foundation:
Value people and collaboration
Deliver working software frequently
Embrace change and learning
Continuously improve
