The Improvement Kata in 10 Minutes

Bill Costantino's classic explanation of the Improvement Kata, originally posted as a SlideCast on November 25, 2011. Awesome!

This video can be used to provide some Improvement Kata / Coaching Kata background content for 'pre-review' online, prior to classroom or practice activities. Here's how to do it:

1) Have your Learners watch the video on their own time before a classroom or practice activity. Tell the Learners to write down what they think are the key points of the video. Tell the Learners that there will be a quiz and that they may be called upon.

2) You (teacher/Coach) should also write down what you think are the key points in the video *before* the classroom/practice activity.

3) Begin the class/practice session by asking Learners what they got out of the video. Write their responses on a flipchart or board. This will help you see how the Learners are currently thinking. The key points that the Learners miss are things you can emphasize in your subsequent instruction and coaching.

In most of the Featureban simulations in the last two years or so, I added Toyota Kata as the retrospective technique from the 2nd retrospective onwards, inspecting the Kanban statistical trends. I moved on from old official Toyota Kata to a solar system metaphorical equivalent, as it was easier to explain. Why the 2nd retrospective onwards, because in the first retrospective, more than one explicit policy changes usually, and Toyota Kata is about which one biggest obstacle to the target condition will we tackle next, based on reading these charts.

More details on Toyota Improvement & Coaching Kata can be found at http://www-personal.umich.edu/~mrother/Homepage.html. I personally like this video demonstration at https://www.youtube.com/watch?v=5pp8JMD-pWQ&t=0s, thinking about how I can apply it in my context.

Crisp's Blog » Improvement Theme – Simple and practical Toyota Kata

Crisp's Blog » Improvement Theme – Simple and practical Toyota Kata | Devops for Growth | Scoop.it

 

I’ve been reading a little bit about Toyota Kata and seen great presentations on the concept. In order to make it practical and useful for me I found myself tweaking it and packaging it in a concept I’ve come to call Improvement Theme. I’ve tried this concept a couple of times now and found it to be a good tool to extend improvements beyond the Retrospective and bringing it into the daily work. In this article I describe how to create the poster and how to use it as a tool for continuous improvements.

 

Mickael Ruau's insight:

The Improvement Theme is a poster. I’ve been using magic charts since they are easily moved between the room in which the retrospective is held and the teams wall.

The charter consists of five areas.
1. Name of the Improvement Theme
2. Now/Problem – Description of the current situation
3. Definition of Awesome – How would we like it to be?
4. Next Target Condition – X weeks from now, what has changed?
5. First Steps – 3 slots for three post-its that describe the first (next) actions we will take?

It’s a living document, preferable put up next to the scrum/kanban wall. Once or twice a week the team reviews the theme and agrees upon new actions as they get completed.

When X weeks has passed the team does a review of the theme itself. If they want to continue on the same theme they identify a new “Next target condition”. Otherwise they create a new Improvement Theme poster.

Here follows an extensive description of how I’ve been using the concept as a tool for improvement and a more in-depth description of the different aspects of the poster.

The Kata Practice for simpler, leaner products through scientific thinking

The Kata Practice for simpler, leaner products through scientific thinking | Devops for Growth | Scoop.it
As much as feedback is at the essence of agile product development, we often fall into the trap of Build-Build-Build and Do-Do-Do and do not seek out customer feedback.
Mickael Ruau's insight:

 

A simple Kata Practice, observed at Toyota and publicised by Mike Rother in his book Toyota Kata, can help us develop a practice of scientific thinking, of goal-setting, measurement, observation and experimentation.

For the KataCon3 conference held in San Diego 2017 this year, I developed a game to help teams practice the Improvement Kata and the Coaching Kata. To replicate the game, you only need a few supplies:

The Dojo – Implementing an Immersive Learning Environment for Teams

The Dojo – Implementing an Immersive Learning Environment for Teams | Devops for Growth | Scoop.it
Has your standard classroom "agile and DevOps learning curriculum" provided the improvements you're seeking for your teams? Based on the philosophy of Japanese places of learning, a **Dojo** - which literally means "place of the way" - is a physical training facility for practitioners of martial arts. Throughout the centuries, these immersive learning environments have instilled the disciplines and skills for students to master their craft. The **Target Dojo** provides a similar immersive learning environment for teams to practice basic kata (actions) related to Lean, Agile and DevOps practices and mindsets via *30-Day Challenges*, where Agile and DevOps (technical) coaches work with teams to help them learn and refine their craft in a dedicated space. In this presentation we'll share with you why Target pursued creating a Dojo for Agile and DevOps learning, how it evolved over its 18 months, the outcomes and success that teams take back with them, and the behavior changes this

Apprendre le Test Driven Development

Apprendre le Test Driven Development | Devops for Growth | Scoop.it


Les katas permettent donc de s'entraîner à différentes techniques, pour le TDD je vous conseille (dans cet ordre) :

FizzBuzz ou Leap Years ;
String Calculator ;
Word Wrap ;
Bowling Game (attention il y a une grande marche par rapport au précédent) ;
Roman Numerals.

Et si vous voulez vous entraîner de manière plus spécifique aux techniques de refactoring :

Tennis ;
Gilded rose (mon grand favori) ;
Trivia.

Je ne peux que trop vous conseiller de faire ces katas, puis de vous entraîner à les refaire régulièrement. Trivia mis à part, tous les katas de cette liste sont faisables en moins de dix minutes donc n'hésitez pas à utiliser des petits moments morts de la journée (retour de déjeuner, avant une réunion, etc.) pour en faire rapidement un.

Quand vous serez suffisamment à l'aise en TDD sur des petits exercices, vous pourrez commencer à inclure cette technique dans votre quotidien !

Remember that the point of the kata is not arriving at a correct answer. The point is the stuff you learn along the way. The goal is the practice, not the solution.

SOAT Blog » Clean Code avec le Kata Video Store » Analyse préliminaire

SOAT Blog » Clean Code avec le Kata Video Store » Analyse préliminaire | Devops for Growth | Scoop.it

Le “Video Store” est un kata de refactoring. On y travaille à améliorer un code existant grâce aux principes Clean Code : le nommage et l’organisation des variables, méthodes et classes, la taille des fonctions (small function, do one thing), la programmation orientée objet (POO)

Cet exercice permet en particulier de :

  • Se frotter aux switch considérés en POO comme « une occasion manquée d’utiliser du polymorphisme. »,
  • Appliquer les principes DRY, à contrebalancer avec DAMP dans les tests (pour favoriser leur expressivité tant que la duplication de code y reste légère), KISS, YAGNI (ne pas aller trop loin dans les refactos).

Démarrage

� Le code est disponible sur ce GitHub.

On commence l’exercice par l’analyse du code en TypeScript et plus particulièrement par ses tests unitaires. Cela permet de saisir plus rapidement la logique métier. On passera ensuite au code de production pour comprendre l’implémentation et identifier les code smells, les parties à refactorer pour obtenir du code plus propre.
