Agile Teams Plan Constantly

• 1-2 times per year • Product evolution over time

• 3-4 times per year • Feature/Date tradeoffs

• Every 2-4 weeks • What will fit in this iteration?

• Every day • How to complete comittement

Planning in Scrum


We Can’t Know Everything Up Front


Agile is Iterative


Accuracy vs. Precision

Plans must be accurate, gain precision over time – We’ll be done in Q3.

– We’ll be done in September.

– We’ll be done on September 10.

Precision is expensive, and more likely to be wrong.

While both accuracy and precision are desirable, accuracy is much more valuable.

Fixed Date!

Fixed Date

What About Utilization?

“Attempts to force non-deterministic systems to operate at greater than 80% efficiency will cause short bursts of stabilization followed by extreme periods of destructive and unpredictable variations from that goal.”

- W. Edwards Deming


The Iron Triangle

Quality is part of scope

– It is built in from the beginning, not “tested in” at the end.

Value is part of scope

– Higher value items are delivered sooner

“Depth” is part of scope

– Do you need a Porsche or will a Kia do?

What is It?

Usually trying to answer questions like…

– How much can be done by a given date?

– When can this set of features be shipped?

– How many teams do we need working on this project?


What is Needed?

Prioritized, estimated backlog

– High level estimates from the team that will likely do the work.

– Prioritized by business value.

Velocity

– Average amount of work a given team can complete in a given sprint.

– Usually use the previous 8 – 12 sprints.


Velocity?

Agile teams usually use relative estimates, not precise estimates

– This feature is about the same as that one.

– Often expressed as Story Points using a modified Fibonacci sequence (1, 2, 3, 5, 8, 13, 20, 40, … )

A team’s Velocity is the sum of the story points for all of the user stories/features that are completed in a sprint


Getting Confidence Intervals

We can obtain the 90% confidence intervals using a team’s historical velocity values from recent sprints.

Sort the velocities from the previous 9 sprints.

Throw out the highest and lowest. The remaining highest and lowest

is your 90% confidence range. www.mountaingoatsoftware.com

has good tools to help with this

Using Confidence Intervals

Apply the confidence intervals to your backlog to get a better idea of how much work will be done by a given date.


We will almost certainly get here (8x26)

At our median velocity, we’ll get here (8x30)

The most we could realistically expect is here (8x32)

Using Confidence Intervals

Apply the confidence intervals to your backlog to determine when a given set of features will be done.

– We will almost definitely be done in 20 sprints (500 / 26)

– At our median velocity, we will be done in 17 sprints (500 / 30)

– The best we could realistically expect is to be done in 16 sprints (200 / 32)
