Amaad Qureshi, a Business Development Manager at Learning Connexions, outlines the importance of agile estimating and planning, focusing on techniques like user stories and story points for project duration estimation. The document explains how tools such as Planning Poker enhance team collaboration in estimating tasks while detailing a practical zoo game for understanding estimation concepts. Additionally, it promotes an upcoming Clean Code workshop aimed at improving coding practices and team communication.

4. What is Agile
Estimating &
Planning?

5. What is Agile Estimating?
Agile Estimating is a method to measure how long it will take to complete a
task
This is done By
Using a teams experience and productivity to derive length and cost
How
By utilising Story Points to work out a teams velocity

6. Story Points

7. Lets Start with User Stories
User Stories are a way of breaking down a project into measurable tasks
that allow you to effectively plan the length of the project and deliver
value to the product/client.
User stories are usually written on post it’s and ask 3 things.

8. User Stories …
Acceptance Criteria (tests) are written on the back of user stories, usually
as 3 or 4 bullet points.
These form the Definition of Done (the tests need to be satisfied for the
task to be completed.

10. Story Points
Story Points tell you how long a user story will take:
 Story points are assigned to user stories by the team carrying out the
task
 Story Points are usually assigned using Fibonacci Numbers: 0, 1, 2, 3, 5,
8, 13, 20, 40 and 100
 The value story points represent are ‘effort’
For example:
 A login screen is a 2.
 A search feature is an 8.

14. How to Estimate
We know…
 That three islands are about the same distance (12) away
 That another island is about twice as far away
We don’t know…
 How long it will take to sail a distance of 12
But we do know…
 That we can sail to all the islands 12 away in about the same time
 That it will take twice as long to the farther island

17. No reliance on actual distances
 We can now reliably estimate how long it will take to get to each of
the four islands.
 Even though we still don’t know how far away each island is.

18. Relating This Back to Software

19. The right tools for
the job

20. Planning Poker®
An iterative approach to estimating
Steps:
 Each estimator is given a deck of cards, each
card has a valid estimate written on it
 Product owner reads a story and it’s discussed
briefly
 Each estimator selects a card that’s his or her
estimate
 Cards are turned at the same time
 Discuss differences (especially outliers)
 Re-estimate until estimates converge

22. Benefits of Planning Poker
 Those who will do the work, estimate the work
 Estimators are required to justify estimates
 Focuses most estimates within an approximate one order of
magnitude
 Combining of individual estimates through group discussion leads to
better estimates
 Emphasizes relative rather than absolute estimating
 Estimates are constrained to a set of values so we don’t waste time in
meaningless arguments
 Everyone’s opinion is heard
 It’s quick and fun

Zoo Game

25. 1. Arrange yourselves in groups
2. Your task is to put the animals in
order of size
3. Assign Zoo Points to estimate
4. Estimate as a group and decide how
many Zoo points each animal should
be assigned
5. If group estimates are different,
discuss then re- estimate
6. Put animals in order of size highest to
lowest
Zoo Game

26. Think about:
1. The discussions you just had in
your groups?
2. Was there high estimates and low
estimates?
3. How did you
decide/compromise?
4. Did your estimates synch up?
(was a 3 zoo point animal the
same size as 1+2 zoo point
animal?)
Zoo Game

27. Estimating Tips
Gut Feeling: use your instinct
Estimate by Analogy: estimating
by comparing
Triangulate: Estimating by
verifying
(is a 3 point story the same as a
1 and a 2 point story)
Disaggregation: If you cant
agree on an estimate try
breaking the user story down
into a smaller story

28. Velocity & Project
duration

29. Duration of Project
1. Work out estimates (story
points) for all user story's in a
project
2. Add up all story points to work
out project length

30. Duration of Project
3. After first few iterations
(development stages)
work out how many
story points are
completed per
hour/day to work out
length of task.
e.g. If a team on avg. completes
2 story points per day:
Velocity is = story points / time
taken
If there are 80 story points in a
project than you can estimate
that it will take 40 days to
complete the project.

31. Duration of Project
Every time you start new projects, use the average velocity of past projects as
a estimate for projected length of new projects.
Past Projects Total Story Points for project
(x)
Team average
Story Points
per/day (y)
Length of
project (x/y)
a 80 4 20 days
b 70 5 14 days
c 85 5 17 days
The more you estimate, the more accurate you will get!
