  1. DISC-overing yourself (and others) to bring out testing at its

    best Linda van de Vooren, Tanja Vos and Yvonne Vos
  2. Safe Space rules 1. Be respectful towards each other 2.

    This is a confidential space: – You can share experiences & lessons afterwards – Do not gossip or share any identifying details about others 3. Devote your full attention to each person who speaks, actively listen 4. Ask follow-up questions if needed 5. Share your appreciation about someone’s question, comment or story 6. Allow each person to take their time and complete their thoughts, please be patient 7. Silence is okay, it can create space 8. Actively invite people into the conversation who have not spoken yet, and remember they can decline without explanation! 9. Remember the humanity: – Expressing one's emotions is not about attacking or invalidating others, including you – Mistakes will be made – Remember rule 1 when expressing yourself 10. Believe in our common best intentions 11. Do you feel unsafe in any way during a session, let us know. We will work with you to resolve the situation 4
  3. Personality type models • Scientists, psychologists and researchers have been

    trying to understand human behavior • There are models with 2 types till 16 types • Type A vs Type B • Left brain vs Right brain • Myer Briggs Type Indicator (MBTI)
  4. Myer Briggs Type Indicator (MBTI) 16 types each with 4

    levels Based on Jung’s theory in his book Psychological Types (1921). 16 personality types based on how they: 1. Gain energy 2. Process information 3. Make decisions 4. Interact with the world.
  5. Personality type models should not be oversimplified nor overcomplicated The

    idea that humans come in 4 patterns has been around a long time
  6. Prophet Ezekiel 590 B.C. – 4 faces Mankind has four

    faces • Lion (courage and strength) • Ox (steadiness and endurance) • Man (wisdom and understanding) • Eagle (vision and perspective) Representing different qualities of mankind
  7. Using the four elements to describe people associated with different

    human qualities and ways of being: Fire people → Action, energy, bold Air people → Ideas, communication, expressive Earth people → Thinking, structure, analytical Water people → Emotion, connection, harmony Empedocles 450 B.C. – 4 elements
  8. Phlegmatic Melancholic Choleric Sanguine Hippocrates 370 B.C. – 4 temperaments

    Our temperament (or humour) is determined by the balance of our 4 essential body fluids Blood → Sanguine → Social, energetic, cheerful Yellow bile → Choleric → Driven, dominant, enthusiastic Black bile → Melancholic → Thoughtful, serious, somber Phlegm → Phlegmatic → Calm, steady, principled
  9. Criticism about DISC • DISC is a simplification; context matters

    • Personalities change and adapt • Don’t put people into a box, people have more than one color • Use to understand differences, not to label • Use as a conversation starter
  10. DISC TOUR: How do I make decisions? Fast. Decide first,

    adjust later. Let's discuss it. Maybe there's an even better idea. Let's make sure everyone is comfortable with it. Let's gather the facts before deciding.
  11. DISC TOUR: How to react to change? Bring it on.

    Sounds exciting! Can we keep some stability? Can we first understand the impact?
  12. DISC TOUR: What is my biggest frustration? Too slow. Too

    boring. Too much conflict. Too little preparation.
  13. DISC TOUR: How much consensus do I need? Minimal. Nice

    to have. Essential. Depends on the evidence.
  14. In a meeting; Should we release this feature? “Yes! Why

    are we still talking about this?” "Before we do, I have three exciting ideas." "Is everyone comfortable with releasing?" "I have prepared a 17-slide risk analysis”
  15. TRIZ Inspired by a Russian approach • Theory of Inventive

    Problem Solving • Creative destruction in groups: stop counterproductive activities & behaviors to make space for innovation • Let’s explore how to make testing fail completely. Every act of creation is first an act of destruction. – Pablo Picasso
  16. TRIZ Rules • Activities are timeboxed, so we stay on

    track • When the bell rings, conversations stop immediately • Use the “finger on lips” signal as a silent way to pause the group • If you see the signal, stop talking and do the same
  17. Groups of 4–6 · Inversion technique 1 Round 1 —

    Make the list: “What would we need to do to guarantee the worst possible outcomes for software testing?” TRIZ
  18. Groups of 4–6 · Inversion technique 1 Round 1 —

    Make the list: “What would we need to do to guarantee the worst possible outcomes for software testing?” 2 Round 2 — Recognize: “Now: where in our current practices do you see any of these behaviours already happening? Circle the ones that feel uncomfortably familiar.” TRIZ
  19. Groups of 4–6 · Inversion technique 1 Round 1 —

    Make the list: “What would we need to do to guarantee the worst possible outcomes for software testing?” 2 Round 2 — Recognize: “Now: where in our current practices do you see any of these behaviours already happening? Circle the ones that feel uncomfortably familiar.” 3 Round 3 — Invert: “For the items you circled, what is the first step you could take to stop doing each one?” TRIZ

Circle the ones that feel uncomfortably familiar.” 3 Round 3 — Invert: “For the items you circled, what is the first step you could take to stop doing each one?” 4 Round 4 — Plenary: Each group shares their top 3 “ uncomfortably familiar” items. Facilitator clusters on the wall in real time. TRIZ
  21. From TRIZ to TRIPS Tune-in Reflect and Interpret on Personality

    Styles Round 5 — Make the list: Individually reflect on the participants in your group. Assign them the colour you think they have. • Who grabbed the pen first? • Who was writing the items on the list? • Who took initiative? • Who gave the summary? Who pushed for speed or decisions? • Who focused on structure or detail? • Who facilitated discussion or energy? • Who supported and stabilised the group? 5 1

    Styles Round 6 — Make the list: Individually reflect on the participants in your group. Assign them the colour you think they have. Who grabbed the pen? Who talked too much? Who pushed for speed or decisions? Who focused on structure or detail? etc. 1 Round 7 — reveal and compare: Share and compare the perceived versus the actual colours. 7 6
  23. From TRIZ to TRIPS What contradictions did you observe in

    your group? 1 •Speed versus Quality? •Harmony versus Challenge? •Creativity versus Structure? •Action versus Analysis?
  24. From DISC to TRIZ 1 • In DISC, collaboration starts

    when we stop judging different behaviors and start understanding the needs behind them. • In TRIZ, innovation starts when we stop choosing between two opposing forces and start understanding the contradiction between them.
  25. Get your sticker • If you managed to slip past

    us at the door, please go get your sticker ☺
  26. What is DISC not? You are not your color. You

    are not confined to your profile or color(s). A profile changes depending on • Your surrounding • Your team • Your energy • Where you are in your cycle • Etc. You can do all colors, at any time. Doing a color far from your ‘home’ color just takes more energy. 41
