Planning Poker
Planning Poker is a go-to estimation technique in agile software development. It's all about getting the team together to figure out how much effort tasks or user stories will take.
How It Works
Here's the deal:
- The Product Owner explains a user story
- Team members ask questions
- Everyone picks a card with their estimate
- Cards are revealed at the same time
- The team talks it out if estimates differ
- Repeat until everyone agrees
It's that simple.
Why It's Useful
Planning Poker isn't just about numbers. It's about:
- Using relative sizing instead of exact time estimates
- Getting the team talking about requirements
- Tapping into the whole team's knowledge
Teams often say their estimates are more on point with Planning Poker. But here's the kicker: the industry average for sprint planning accuracy is still below 50%. Estimation in software dev? It's tough.
Getting Everyone Involved
Planning Poker gets everyone in on the action:
- Product Owner breaks down the stories
- Devs, testers, and designers all chip in
- Everyone votes independently
- Discussions iron out any differences
This approach? It leads to better task understanding and a more engaged team.
Is It Hard to Do?
Planning Poker isn't rocket science, but it takes some getting used to:
- Setup
You need Planning Poker cards. Most teams use the Fibonacci sequence (0, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89).
- Challenges
- Avoiding groupthink
- Keeping discussions on track
- Dealing with complex tasks
- Solutions
- Use a moderator
- Set time limits
- Break down big tasks
With some practice, Planning Poker can become a smooth part of your agile process.
2. T-Shirt Sizing
T-Shirt Sizing is a quick estimation technique in Agile. It uses clothing sizes (XS, S, M, L, XL) to group tasks by complexity or effort.
Accuracy
T-Shirt Sizing gives rough estimates:
- Great for early project stages
- Helps teams avoid number crunching
- Less precise than other methods
Here's a typical scale:
Size
Estimated Time
XS
1-2 Weeks
S
2-4 Weeks
M
1-2 Months
L
2-4 Months
XL
4+ Months
Team Involvement
It gets everyone involved:
- Sparks discussions about task complexity
- Team members share views quickly
- Builds shared project scope understanding
Difficulty Level
T-Shirt Sizing is easy to use:
- Intuitive for new team members
- Fast for estimating large backlogs
- Teams must define size meanings clearly
To use it well:
- Set clear size criteria
- Include whole team in estimations
- Use for high-level planning
- Adjust sizes as you learn more

3. Dot Voting
Dot Voting is a quick way for teams to prioritize items or make decisions together. It's popular in agile teams for things like sprint retrospectives and feature prioritization.
Accuracy
Dot Voting shows group preferences visually, but it's not perfect:
- It's better for rough prioritization, not precise estimates
- Popular ideas might win over less-known but valuable options
- Groupthink can skew results if you're not careful
To get better results:
- Set clear voting rules
- Give time for research before voting
- Use digital tools to keep votes private
Team Involvement
Dot Voting gets everyone involved:
- All team members have an equal say
- Quiet team members can easily participate
- It sparks talks about priorities and trade-offs
"Dot Voting changed our sprint planning. Everyone got to contribute, bringing in more diverse views and better decisions", said a product manager at a top tech company.
Difficulty Level
Dot Voting is pretty simple:
Step
What to Do
Setup
Write ideas on sticky notes or a digital board
Voting
Give each person 3-6 dots (about 25% of total ideas)
Process
People put dots next to their preferred options
Tallying
Count dots to see what's most popular
To make it work:
Clearly explain the options
Set a dot limit for each person
Vote silently to avoid influencing others
Talk about the results afterward
Dot Voting is easy, but it might not work for complex decisions. Use it as part of a bigger decision-making process for tricky project estimates.
Good and Bad Points
Let's break down the pros and cons of Planning Poker, T-Shirt Sizing, and Dot Voting.
Method
Pros
Cons
Planning Poker
• Team talks boost accuracy
• Anonymous voting cuts bias
• Great for small teams
• Slow for big backlogs
• Needs task familiarity
T-Shirt Sizing
• Quick and easy
• Good for big-picture planning
• Moves beyond time units
• No standard number scale
• Size meanings can be fuzzy
Dot Voting
• Fast for big backlogs
• Simple and visual
• Helps set priorities
• Less accurate
• Group thinking can skew results
• Better for rough guesses
Planning Poker shines in teamwork. It's perfect for sprint planning, but it's not quick. The Hubstaff Content Team says:
"On our Sprint calls, we figure out story points (1-5) for things like blog posts, editing, CMS work, emails, and other content."
T-Shirt Sizing is fast and casual, great for long-term plans. It works well for creative tasks:
"Use T-shirt sizes for video work. A quick Instagram reel? Extra small. A live product demo? XL."
Dot Voting is speedy but can lack depth. It's best for quick priority-setting, not detailed estimates.
When picking a method, think about:
Team size: Planning Poker for small teams, Dot Voting for bigger groups.
Backlog size: T-Shirt Sizing and Dot Voting for big backlogs. Planning Poker for 10 or fewer tasks.
Detail needed: Want precision? Planning Poker. Rough estimates? T-Shirt Sizing or Dot Voting.
Team know-how: Planning Poker needs task familiarity. T-Shirt Sizing works for new teams.
Time available: Dot Voting is fastest, then T-Shirt Sizing. Planning Poker takes longest but often gives better results.
Wrap-up
Planning Poker, T-Shirt Sizing, and Dot Voting each serve a purpose in agile estimation. Here's when to use each:
Planning Poker:
- For small teams (up to 8 people) and fewer tasks (10 or less)
- Promotes team discussion and consensus
- Used by Hubstaff's content team in Sprint calls
"On our Sprint calls, we assess story points (1-5) for blog posts, editing, CMS work, emails, and other content."
T-Shirt Sizing:
- For high-level portfolio planning and creative tasks
- Quick, easy, and moves beyond time units
- Useful for video content creation
"Use T-shirt sizes for video creation. An Instagram reel might be XS, while a live product demo could be XL."
Dot Voting:
- For large backlogs and big teams
- Fast and helps set priorities
- Best for rough estimates and quick priority-setting

"None of us is as smart as all of us."
This captures the essence of these techniques – tapping into collective wisdom. Choose the right method to leverage your team's knowledge for better estimates and successful projects.
FAQs
Is Planning Poker a consensus-based technique?
Yes, it is. Planning Poker gets the whole team involved in estimating effort for user stories or tasks. Here's how it works:
- Teams use cards with values from a modified Fibonacci sequence
- Everyone picks a card to represent their estimate
- Cards are revealed at the same time
- The team discusses and agrees on a final estimate
This approach helps the team reach a consensus on effort estimates.
Is planning poker effective?
Planning Poker works well for estimating complex work in software development. Here's why:
- Gets everyone involved, tapping into team knowledge
- Reduces bias by revealing estimates at the same time
- Encourages team members to explain their thinking
- Focuses on comparing task complexity, not exact time
A Mountain Goat Software study found Planning Poker estimates were 40% more accurate than traditional methods.
What are the drawbacks of planning poker?
Planning Poker isn't perfect. Here are some potential issues:
Drawback
Description
Time-consuming
Can take a while for big backlogs
Strong personalities
May sway others' estimates
Point obsession
Teams might focus too much on story points
Estimation burnout
Too many sessions can wear teams out
To tackle these problems, teams can:
Limit items per session
Switch up who leads the session
Use silent voting to cut down on bias
Focus on relative sizing, not exact point values
"Good Planning Poker balances thorough discussion with quick decisions. It's about agreeing, not being perfect", says Mike Cohn, Scrum Alliance co-founder.
