Against All Odds

Aug 5, 2010

The San José Mine Collapsed

IF the miners had survived and followed protocol, they would be in a ‘refuge’ area with enough food for 10 people for 2 days and water for a month.

The Rescue Team

Sponsor: President Sebastián Piñera Leader: André Sougarret

– Codelco Mine Manager The Leadership Team:

32 Handpicked Codelco Mangers

The Rescue Effort

Step 1 – Drill to the refuge area Many quick probes to learn how to drill accurately. [17 days]

Step 2 – Rescue the miners Try Plans A, B, and C to see which is fastest. [52 days – Plan B wins]

Success!

Four Lessons

The Power of Challenge Not Too Easy, Not Too Hard

“The best moments [in our lives] usually occur

when a person’s body or mind is stretched to

its limits in a voluntary effort to accomplish

something difficult and worthwhile.”

Mihaly Csikszentmihalyi - 1991

Think Try Learn Dynamically Intertwined Execution and Adaptation

In today’s world of apps and platforms, the

boundary between developing and deploying

software has largely disappeared. Continuous

Delivery is now standard engineering practice

for the web, cloud, mobile and Saas space.

The Need for Expertise And Expert Leaders

There are no instant experts in chess…

We would estimate, very roughly, that a

[chess] master has spent perhaps 10,000

to 50,000 hours staring at chess positions.

Herbert Simon and William Chase - 1973

It’s Not About Money Energized Workers Delighted Customers Sustainable Profits

The energy fueled

by being part of

a winning team.

The pride of a

job well done.

Remember times when:

You are deeply engaged

Distractions disappear

Time evaporates

This is called FLOW.

Solution sets converge through a series of Integrating Events (IE’s) before detailed design begins.

Have You Tested It?

Goal: Every two weeks, over a 48 hour weekend, software

will be validated by placing 55,000 units in test sockets.

Feasibility: Robot specs show it is capable of doing this.

Coach: Have you tested it?

Team: No…but –

Team decided to test 1500 parts.

Robot broke down after 80….

It took a year of improvements

for the robot to work reliably at

the needed volume and speed.

Lesson 2: The Need for Expertise

Decades of successful software engineering without detailed specifications, a backlog of stories, or long list of features and functions.

Requirements for a Process Control System

1. It has to make good product.

2. It MUST be on time.

3. Operators must find it convenient to use.

4. It will be maintained by the plant engineer.

5. It should contain the latest technology.

Where Does Expertise

Come From?

10 Years / 10,000 hours of Deliberate Practice Identify a specific skill that needs improvement.

Devise (or learn from a teacher) a focused exercise: – designed to improve the skill.

Practice repeatedly.

Obtain immediate feedback: – adjust accordingly.

Focus on pushing the limits: – expect repeated failures.

Practice regularly & intensely: – perhaps three hours a day.
