Three baseline metrics
and what they can tell
you about your team

Why did I start thinking about metrics
and using them to help my teams?
What’s the difference between a metric and a measure?
Measure
Raw data, unorganized
facts that need to be
processed.
The numbers we capture.
“I am 178cm tall”
Metric
Processed, organized, structured or
presented data in a given context so
as to make it useful.
Metrics are the information we can
generate based on the measures.
“I’ve lost 5kgs in the last 2 months”
Where did I start…
• Number of defects found
• Total number of stories (or tasks or defects) completed
• Number of lines of code
• Number of workshops
v. gamed
To manipulate dishonestly for personal gain. To
be messed up or screwed overhttp://www.urbandictionary.com/define.php?term=gamed#3866612 &

Vanity metrics are the numbers you want to publish on
TechCrunch to make your competitors feel bad.
Eric Ries
Number of:
• Downloads – “Over 1 million downloads!”
• Registered users – “10 million registered users”
• Tweets a day – “1 million tweets per day”
• Daily/Monthly Active Users
• Daily/Monthly sessions per user
Metrics
are
a
mirror
“Are these going to
affect my monthly one-
on-one?”
“Are you going to compare us
to another team now?”
“What about this
other metric (usually
a vanity metric) isn’t
one that better to
show the boss?”
To make a suit that fits right,

The twelve principles of agile development include:
• Customer satisfaction through early and continuous software delivery
• Accommodate changing requirements throughout the development process
• Frequent delivery of working software

What metrics did I use and
what did they tell me about my teams?
Metric 1: Cycle Time
From cut to fit
Cycle Time:
Time taken from starting to finishing a piece of work.
Time taken to “do” the work – from being defined to being done.

“If you don’t measure something, you can’t change it”
Mitt Romney
If you don’t measure something and use it in a metric,
you can’t know if the change you make is working
