Prepare Your Table

OLD NEW MISSING

Prepare the table for the Signals

The system is really the people. It exists in their minds, in their behaviors and their interactions. It is a much more complex structure than any fixed hierarchy would suggest.

Signals In Our System

Identify new signals you need FROM the system to support Scrum



2 Place each signal in the “NEW” section

Ken Schwaber Jeff Sutherland

…burn-downs, burn-ups, or cumulative flows […] do not replace the importance of empiricism. Only what has happened may be used for forward-looking decision-making.

What about the new charts?

Reprogramming this system is a highly complex task. Scrum introduces (4) new events, (3) new roles, (3) new artifacts, new language, and a new mindset.

Failure Demand

Value demand is “what the service exists to provide”

Failure demand is “demand caused by a failure to do something or do something right for the customer”

Failure demand is discovered during the application of the Vanguard Method to service organizations. The Vanguard Method is a method used by service organizations to change from a command and control to a systems approach to the design and management of work.

César Idrovo 2015

Failure Demand

“Remember, all time spent handling failure demand is waste. So it is usually better to create a map of the process that creates failure, rather than mapping the process that handles failure. Your objective is not to handle failure demand more efficiently, it is to eliminate failure altogether. Before mapping the flow of failure demand, ask yourself: What is causing the development process to produce failure demand in the first place? What can be changed in the process to prevent (or dramatically reduce) the failure demand?”

- Leading Lean Software Development, Mary & Tom Poppendieck

César Idrovo 2015

Failure Demand

•  Technical Debt, shortcuts, missing (or not yet automated) tests, poor integraIon

•  Responding to Customer or Agent issue with soLware / website / process

•  Customer Service (or scrum team) discovering bug or unintended “feature” in the soLware

•  PrioriIzing bug, invesIgaIng fix, wriIng fix •  Preparing patch, deploying patch, related communicaIons

”But today was the first time I have used a taller vehicle.”

César Idrovo 2015

Effective signals allow recipients to

own the outcome. They do not

absolve the signal “senders” from

responsibility, accountability or

consequences.

“Risk transfer” is not a suitable goal

for any signal (or process), because

the risk still exists inside the

broader system.

Is “Risk Transfer” already present in your system?

“Fewer Bugs” Signal

César Idrovo 2015

Map the “Elk” causality (i.e. 2-way) of signals you receive (or send!)


1 Select desired effect (eg “Fewer Bugs”)

2 Identify what signal could cause that effect

3 Identify other consequences of that signal César Idrovo 2015
