ABOUT YOU…

Take a few minutes, get to know each other‣ Tell a story about your weirdest job

LOCAL OPTIMIZATIONIs the enemy of a well working system

LOCAL OPTIMIZATION EXAMPLE 1 : FOCUS ON CHOPPING TOMATOES OVER DELIVERING FOOD

LOCAL OPTIMIZATION EXAMPLE 2 : FOCUS ON PLAYER JOB TITLE OVER MOVING THE BALL?

EXAMPLES OF LOCAL OPTIMIZATIONS

what are examples of local optimizations you have witnessed?

CAUSATION FALLACY:

WE BELIEVE THAT VERY EFFECT HAS A CAUSE… AND WE CAN TELL WHICH IS WHICH.

Systems thinking is a discipline for seeing whole rather than parts

For seeing patterns of change rather that static snapshots, and for understanding and subtle interconnectedness that gives living systems their unique character.”

THERE IS NO BLAME

System modeling (aka Causal loop diagram) is a tool to learn and better understand system dynamics.

Using system modeling helps us to apply a systems thinking approach.

SYSTEM MODELING BASICS

Linear - More A leads to more B

Opposite - More A leads to less B

Delayed - More A leads to more B with a delay

SYSTEM OF (NOT) DOING HOMEWORK“My child often does not do his homework because he prefers to play with the computer or watch tv”

Start with these attributes (verbatim)

‣ % of homework complete

‣ amount of homework pending

‣ Time required to prepare homework

‣ Difficulty of homework

REVISIT YOUR SYSTEM MODEL Can you detect relationships that are not “absolute truth” but a results of your assumptions?

For each relationship that is based on an assumption add a visual element to mark the assumption

A BASSUMPTION WE HAVE EXPLAINING WHY A->B

WEINBERG-BROOKS’ LAW:

MORE SOFTWARE PROJECTS HAVE GONE AWRY FROM MANAGEMENT’S TAKING ACTION BASED ON INCORRECT SYSTEM MODELS THAN FOR ALL OTHER CAUSES COMBINED.

SYSTEM OF DELIVERING VALUE TO CUSTOMERS

“Our teams don't deliver enough value to our customers”

Start with these attributes (verbatim)

‣ Amount of Value delivered (in $$$)

‣ Number of bugs in the software

‣ Number of people on our program

‣ Time invested in Refactoring

WE ARE LOOKING FOR REINFORCING FEEDBACK LOOPS

DETECT THE LOOPS IN YOUR SYSTEM

What can you do in order to:‣ Amplify these loops.‣ Reduce impact of these

loops

SYSTEM MODELING

‣ Gather multiple people that represent different aspects of the situation.

‣ Describe the situation or dynamic you want to investigate

‣ Collect measurable factors related to the situation.‣ Start building your model‣ Add assumptions, factors, relationships.‣ Observe the outcome and suggest experiments
