🎯 Estimation & Planning in Agile

How Teams Guess Smart and Plan Together

Imagine you’re packing for a family road trip. You don’t know exactly how long the drive will take, but you know going to Grandma’s house (2 hours away) is shorter than going to the beach (6 hours away). You’re comparing trips, not measuring them perfectly. That’s exactly how Agile teams plan their work!

🏠 The Big Picture: What is Agile Planning?

Think of building a LEGO castle. You don’t build the whole thing at once. Instead:

1. First, you decide what the castle should look like (Product Roadmap)
2. Then you pick which parts to build this week (Release Planning)
3. Finally, you figure out how hard each piece is (Story Points)

Agile planning is about:

• Making smart guesses (not perfect predictions)
• Working together as a team
• Adjusting plans as you learn more

📏 Relative Estimation

Comparing, Not Measuring

The Simple Idea: Instead of saying “This task takes exactly 4 hours,” we say “This task is BIGGER than that one.”

🍕 Pizza Example

Imagine ordering pizzas:

• Small pizza = Easy task
• Medium pizza = Medium task
• Large pizza = Hard task

You don’t need to know exactly how many slices—you just know large > medium > small!

    B --> C[Large Task 🍕🍕🍕]

    style B fill:#FFD700
    style C fill:#FF6B6B

Why Relative Works Better

Real Example: “Writing the login page is about the same size as writing the signup page, but smaller than building the shopping cart.”

🔢 Story Points

Our Special Counting System

What Are Story Points? Story points are like “difficulty coins” we give to tasks. They measure:

• How complex is it?
• How much work is it?
• How risky or unknown is it?

🎮 The Fibonacci Sequence

Teams use special numbers: 1, 2, 3, 5, 8, 13, 21

Why these weird numbers? Because the bigger something gets, the fuzzier our guess becomes!

💡 Remember

Story points are NOT hours! A 5-point task isn’t “5 hours of work.” It means “this feels about 5 times as complex as our smallest task.”

🃏 Planning Poker

A Game Where Everyone Wins

How to Play:

1. Get Your Cards 🎴 Each team member gets cards with numbers: 1, 2, 3, 5, 8, 13, 21

2. Hear the Story 📖 Someone reads what needs to be built

3. Pick Your Card (Secretly!) 🤫 Everyone chooses a number WITHOUT showing others

4. Reveal Together 🎉 “3… 2… 1… SHOW!” Everyone flips cards at once

5. Discuss Differences 💬 If someone picked 2 and another picked 13, they explain why!

6. Vote Again 🔄 After discussion, vote again until you agree

graph TD
    A[Read User Story] --> B[Everyone Picks Card]
    B --> C[Flip Cards Together]
    C --> D{Do Cards Match?}
    D -->|Yes| E[Record Points ✅]
    D -->|No| F[Discuss Differences]
    F --> B

Why Planning Poker Works

• No copying! Since everyone picks secretly, no one just follows the loudest person
• Everyone’s voice matters The quiet intern and the senior developer have equal votes
• We learn from differences Different numbers = different perspectives = better understanding

Example Conversation:

Developer 1: “I said 3 because it’s like the form we built last week.”

Developer 2: “I said 8 because I see hidden complexity in the validation rules.”

Team: “Ah! Good point. Let’s go with 5.”

🔮 Cone of Uncertainty

Why Our Guesses Get Better Over Time

The Truth About Predictions:

At the START of a project, our guesses can be 4x too low or 4x too high!

As we learn more, our guesses get closer to reality.

graph LR
    A[Project Start<br/>😰 Very Unsure] --> B[Some Work Done<br/>🤔 Getting Clearer]
    B --> C[Halfway Through<br/>😊 Pretty Confident]
    C --> D[Near End<br/>✅ Very Accurate]

📊 The Numbers

What This Means for You

1. Don’t promise exact dates early - “We’ll be done in 6 months” might become 1.5 months or 24 months!
2. Expect to re-estimate - Your guesses SHOULD change as you learn
3. Start small - Do a little work first, then estimate again

Real Example: “Building this app? Could take 3 months… could take 12 months. Let’s build a tiny version first, then we’ll know better!”

📊 Agile Planning Levels

From Big Dreams to Daily Tasks

Think of planning like a telescope with different zoom levels:

graph TD
    A[🌟 Vision<br/>Years ahead] --> B[🗺️ Product Roadmap<br/>6-12 months]
    B --> C[📦 Release Planning<br/>1-3 months]
    C --> D[🏃 Sprint Planning<br/>1-2 weeks]
    D --> E[📋 Daily Planning<br/>Today's work]

Each Level Explained

Example - Building a Food Delivery App:

• Vision: “Best food delivery app in the city”
• Roadmap: Q1: Ordering, Q2: Payments, Q3: Reviews
• Release: “January release = basic ordering works”
• Sprint: “This week = menu display + add to cart”
• Daily: “Today = show restaurant list”

📦 Release Planning

What Are We Shipping and When?

A release is a bundle of features you give to users. Release planning answers:

• Which features go in this release?
• When do users get it?
• How do we know it’s ready?

🧮 The Math Behind Release Planning

Step 1: Know Your Velocity Velocity = How many story points your team finishes per sprint

Example: Team finishes ~20 points every 2-week sprint

Step 2: Count Total Points Add up all the stories you want in the release

Example: 80 points of features for Version 2.0

Step 3: Calculate Sprints Needed 80 points ÷ 20 points/sprint = 4 sprints (8 weeks)

graph LR
    A[80 Points<br/>Total Work] --> B[÷ 20 Points<br/>Per Sprint]
    B --> C[= 4 Sprints<br/>8 Weeks]

Release Planning Tips

1. Leave buffer time - Things ALWAYS take longer than expected
2. Prioritize ruthlessly - What MUST be in this release?
3. Plan for learning - First sprint is often slower as team learns

🗺️ Product Roadmap

Your GPS for the Next 6-12 Months

A Product Roadmap shows:

• Where are we going? (big goals)
• What comes first? (priorities)
• What comes later? (future plans)

🎯 Roadmap Structure

Good Roadmap vs Bad Roadmap

❌ Bad Roadmap: “By March 15th, we’ll have feature X with 47 sub-features complete” (Too specific! Too far ahead!)

✅ Good Roadmap: “Q1 focus: Core user experience. Specific features TBD after sprint 1 learnings.” (Flexible! Allows learning!)

Example Roadmap

graph LR
    A[Q1 2024<br/>🏠 Core Features] --> B[Q2 2024<br/>📱 Mobile App]
    B --> C[Q3 2024<br/>💰 Monetization]
    C --> D[Q4 2024<br/>🌍 Global Launch]

Remember: A roadmap is a plan, not a promise. It WILL change as you learn!

🌟 Key Takeaways

1. Compare, don’t measure - Relative estimation beats hour counting
2. Use story points - Fibonacci numbers (1,2,3,5,8,13,21) for sizing
3. Play planning poker - Everyone votes secretly, then discusses
4. Accept uncertainty - Early guesses are fuzzy, and that’s okay!
5. Plan at different levels - Vision → Roadmap → Release → Sprint → Daily
6. Release in chunks - Deliver working software regularly
7. Roadmap is flexible - It guides, but doesn’t lock you in

💪 You’ve Got This!

Agile planning isn’t about being perfect—it’s about being smart and adaptive. You now know:

• How to size work without getting stuck on hours
• How to get everyone’s opinion fairly
• Why early estimates are uncertain (and that’s fine!)
• How different planning levels work together

The best Agile teams don’t predict the future—they prepare for it, adjust as they learn, and deliver value along the way.

Happy Planning! 🚀
