Osmosis


Finding Mob Programming From a non-programmer to

a programmer through osmosis


Only tester by profession & only

woman in my team


Testers don’t break the code, they break your illusions about

the code. - Adapted from James Bach


“Women only write comments

in code”


Dislike of programming

(Basic, Scheme, Assembler, Fortran, C++, C, Java, Pascal, Python, C#, Ruby,

JavaScript, Objective C, Swift …)


There was a need of a change of ideas…

A talk on a strange idea: Mob Programming


"All the brilliant people working on the same thing, at the same time, in

the same space, on the same computer." -- Woody Zuill


Trying it out at office and in meetups


Safety is a prerequisite for learning


Correcting Mistakes without

Egos in Play


Knowing what is relevant


Slow allows for thoughtful thinking


Stealth Exploration


An All-Female Hackathon


Programming is like writing. Getting

started is easy and it takes a lifetime to

get good at.


I had great ideas even if I did not know how to turn them to code –

removing the distance is worth the struggle.

Retrospectives


If everyone is contributing or learning it’s the right size


Two ideas, bias to action and do both!


Best ideas win when you care

Learning in a Mob Moving towards Serendipituous Learning


Exploratory Testing Test Automation

Unit Testing Application Programming

Performance Testing Security Testing


Mob Testing


Cognitive Dissonance


Accidental Learning by being Intentional

about Learning


5.5 hrs of learning and 2.5 hrs of working puts you ahead after 1 year if the gain daily is 1%.

On being the best…

vs.

Linear Viewpoint

I know everything

you do!

You have nothing left

to teach me

Reality

I know more than you do!

There is still so much more I

can learn from you


Experts are not the ones who know the most but ones who learn the fastest

Comparison

Strong Style Traditional

I have an idea… Please take the

keyboard

I have an idea… Give me the

keyboard


“I never knew testing was this

much fun”


“It only took 40 seconds for your second test

automation pull request to get approved!”


People change their minds when their

experience conflicts with their beliefs


Less regulation as common style emerges. – Philipp Lüthi
