Keeping Pace
! Our modern world runs on software.
! What doesn't now, likely will soon
! We’ve had Moore’s Law for hardware, and Moore’s Law
+ for envisioning what software could do
! But, our prior development practices haven’t kept pace
! Agile shows the greatest promise, but was developed
for small teams
! We need a new approach – one that harnesses the
power of Agile and Lean
– but applies to the needs of the largest software
enterprise
Our development methods must keep pace with an
increasingly complex world

First, Some Thoughts on Agile Methods
! Scrum
– Works great. Less filling. Ubiquitous. Scrumptious. Let’s Sprint.
! Extreme Programming
– Really great code from really great coders.
We can scale great code. Extremely useful. Let’s Program with it.
! Kanban
– Clear thinking on flow, demand management and limiting wip.
Let’s flow, limit WIP and manage demand with it.
! But if these innovative methods don’t have the native constructs to
address the view beyond the team − the systems view − shouldn’t
we do something about that?
! And, on behalf of millions of practitioners, working on really big
systems in really big companies, and struggling badly with existing
approaches, don’t we have an obligation to try?

Goal: Speed, Value, Quality
THE GOAL
! Sustainably shortest lead time
! Best quality and value to
people and society
! Most customer delight, lowest
cost, high morale, safety
All we are doing is looking at the
timeline, from the where the customer
gives us an order to where we collect
the cash. And we are reducing the time
line by reducing the non-value added
wastes. – Taiichi Ohno
We need to figure out a way to deliver
software so fast that our customers
don’t have time to change their minds.
̶ Mary Poppendieck
Most software problems will exhibit
themselves as a delay.

Product Development Flow
1. Take an economic view
2. Actively manage queues
3. Understand and exploit
variability
4. Reduce batch sizes
5. Apply WIP constraints
6. Control flow under uncertainty:
cadence and synchronization
7. Get feedback as fast as
possible
8. Decentralize control

Reduce Batch Size
Small batches go through the system faster with lower
variability
! Large batch sizes increase variability
! High utilization increases variability
! Severe project slippage is the most
likely result
! Reducing batch size
– Reduces cycle time; faster
feedback
– Decreases variability and
risk
! Most important batch is
the transport (handoff)
batch
! Proximity (co-location)
enables small batch sizesProject slippage rises exponentially with duration

Actively Manage Queues
! Understand Little’s Law
(Avg wait time = avg queue
length / avg processing rate)
! Faster processing time
decreases wait
! Control wait times by controlling
queue lengths
Reinertsen, Don. Principles of Product Development Flow
Email from a client service organization: “Thank you for contacting us. We
are experiencing increased volumes and apologize in advance for the
delay. Our goal is to contact you within...”

Apply WIP Constraints
WIP constraints force capacity matching, increases flow
When WIP and utilization become too high, you will see a sudden and
catastrophic reduction in throughput!
Apply WIP constraints
Force capacity matching
Accelerate delivery
Timebox
Prevent uncontrolled expansion of work
Make waiting times predictable
Purge lower value projects
when WIP is too high
Increase efficiency and throughput of
remaining work
Constrain local WIP pools Constrain global WIP pools
Make WIP continuously
visible
1) Understand 2) take action

Systems Must be Managed
A system must be managed. It will not manage
itself. Left to themselves, components become
selfish, competitive, independent profit centers,
and thus destroy the system. . . .
The secret is cooperation between components
toward the aim of the organization.

Scaling to the Portfolio
“A system is a network of interdependent
components that work together to try to
accomplish the aim of the system.
A system must have an aim. Without an
aim, there is no system.”

The Management Challenge
It is not enough that management
commit themselves to quality and
productivity, they must know what it is
they must do.
If you can’t change the system who can?
