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 enterprises
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 enterprise and 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?

Scaling, You Have a Choice
You have a blank slate.
Figure it out what works and grow it to suit you.

Or Start with A Proven Framework
A proven, publicly-facing framework for applying Lean and Agile practices at enterprise scale
! Synchronizes alignment, collaboration and delivery for large numbers teams
Core values: 1. Code Quality 2. Program Execution 3. Alignment 4. Transparency

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. – Al Shalloway

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 Reinertsen, Don. Principles of Product Development Flow

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 sizes
Project slippage rises exponentially with duration

Visibility and WIP Constraints
Question: How is this team doing? How do you know that? What would be the affect of a three story WIP constraint on Dev and Test

Let’s Look at the Framework

Nothing Beats an Agile Team ! Empowered, self-organizing, self-managing cross-
functional teams ! Valuable, fully-tested software increments every two weeks ! Scrum project management practices and XP-inspired
technical practices ! Teams operate under program vision, system, architecture
and user experience guidance ! Value description via User Stories

That Focuses on Code Quality
You can’t scale crappy code
Agile Architecture
Con/nuous Integra/on
Test-‐First
Refactoring
Pair Work
Collec/ve Ownership
Code Quality Provides: ! Higher quality products and
services, customer satisfaction
! Predictability and integrity of software development
! Development scalability
! Higher development velocity, system performance and business agility
! Ability to innovate
Code Quality

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. – W. Edwards Deming

Scale to the Program Level
! Common sprint lengths and estimating ! Face-to-face planning cadence for collaboration,
alignment, synchronization, and assessment ! Value description via Features and Benefits
! Self-organizing, self-managing team-of-agile-teams ! Continuous value delivery ! Aligned to a common mission via a single backlog

Cadence-Based Cross-Functional Planning
! Two days every 8-12 weeks ! Most attend in person ! Product/Program Management/System Engineering owns
feature priorities ! Development team owns story planning and high-level estimates ! Architects, systems engineers work as intermediaries for
interfaces, and dependencies
Cadence-based Planning meetings are the “pacemaker” of the agile enterprise

DevOps
1. Build and maintain a production-equivalent staging environment
2. Maintain development and test environments to better match production
3. Deploy to staging every sprint; deploy to production frequently
4. Put everything under version control
5. Start creating the ability to automatically build environments
6. Start automating the actual deployment process
Tangible value occurs only when the end-users are successfully operating the software
Deployment pipeline streamlines delivery

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.” – W. Edwards Deming

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?

Lean Foundation: Leadership
1. Take an economic view of the full value chain
2. Embrace the Agile Manifesto 3. Develop people, not things 4. Own the system of which they
speak 5. Decentralize control 6. Unlock the intrinsic motivation
of knowledge workers 7. Implement software
development flow. Visualize work. Manage work in process.
8. Build high-performing Agile teams
