Transcript of Impact of Agile Quantified

One out of four team members change every 3 months.
Stable teams result in up to
60% better Productivity
40% better Predictability
60% better Responsiveness
Small teams (of 1-3 people) have
Worse Predictability and Quality
But Better Productivity
Larger teams seem to perform OK
The Most Obvious Finding
Little's Law
The Most Dramatic Finding
"Lightweight Scrum" performs best overall
But teams doing Full Scrum have the best Quality

(From the Matrix)
This is your last chance. There is no turning back. You take the blue pill, the story ends. You believe what ever you want to believe.... Remember, all I'm offering is the truth, nothing more.

Teams that aggressively control WiP:
cut time in process in half
have 1/4 as many defects
But if taken too far,
Productivity can be 34% lower
"Choose wisely..."
"I only offer the truth."
Progression of human reaction to evidence that goes against our bias

2. The presenter must have an agenda.

1. Using metrics as levers to change someone else’s behavior
2. Unbalanced
3. Believing metrics can replace thinking
4. Too costly metrics

5. Using a convenient metric

6. Using bad analysis

7. Forecasting without discussing probability
"What gets measured
gets done."
Lord Kelvin, "…when
you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory
A fact without a theory
is like a ship without a sail,
is like a boat without a rudder,
is like a kite without a tail.
A fact without a figure
is a tragic final act.
But one thing worse
in this universe
is a theory without a fact.
