What is Water Spider in Lean? | Kanban Tool

What is Water Spider in Lean? | Kanban Tool | Devops for Growth | Scoop.it
A water spider is a Lean production personnel role centered around timely and accurate stock replenishment. The water spider team member is much like a mobile Kanban system that refills the production line with the required materials to maintain a steady flow.

The person filling a water spider position needs to have a good understanding of the process, excellent communication skills, and has got to be able to follow standardized routes.

The water spider term was inspired by an insect known as a whirligig beetle, Mizusumashi in Japanese. Whirligigs appear to be able to hang between the water and the air while quickly going from place to place, keeping both of the environments in their sight simultaneously. How a water spider stock manager moves about the production floor, and the way they perceive all production steps at once, resembles the beetle’s movements and sight, giving the role its name.

Prioritization with Pugh

Prioritization with Pugh | Devops for Growth | Scoop.it

Reading further along in the article, you learn they solved this problem by scoring each feature (on a scale of 0 to 3) how well each feature met twenty-two key attributes from the perspective of both the business and the system.  The features that scored the highest were moved to the top of the prioritization queue and the ones which scored the lowest moved to the bottom.  What broke the logjam for them was having the ability to talk about the features using data and moving away from advocacy.

 

What Brandon described is essentially Pugh Concept Selection – a Design for Six Sigma tool.  Bernie Thompson gives an excellent description on his blog of using a more “pure” application of Pugh to select between different cell phone plans.  Pugh was originally used to rank various design alternatives during Analyze, but again the Lean world has yet another mature tool that the Agile community can apply in our lightweight environments.

Mickael Ruau's insight:

Optimisation de la production

 Six grandes pertes : font référence aux six principales causes de pertes de production généralement rencontrées dans les processus de fabrication, à savoir : les interruptions, les réglages, les petits arrêts, la vitesse réduite, les pannes de démarrage et les pannes en cours de production.

 Flux continu : méthode de production consistant à traiter une pièce à la fois ou en quantité très restreinte. Les différentes opérations s’effectuent de manière successive, sans arrêt du processus.

 Heijunka : inventée par Toyota, cette technique consiste à lisser une production sur une période donnée afin de gagner en stabilité, de simplifier la gestion des ressources humaines ou encore de réduire la pression subie par la chaîne logistique.

 Fabrication cellulaire : méthode de fabrication consistant à organiser une production de manière spécifique (en U et en flux continu, par exemple), la fabrication ou l’aménagement cellulaire permet une optimisation de la production.

 Andon : outil de gestion prenant la forme d’un système lumineux et sonore, l’andon permet d’identifier et donc de traiter rapidement un incident sur une chaîne de production.

 Jidoka : également connu sous le terme d’autonomation ou d’auto-activation, le Jidoka permet à une machine d’avertir automatiquement un opérateur, par le biais d’un andon par exemple, lorsqu’elle identifie un dysfonctionnement, permettant ainsi d’éviter une production non conforme ou un accident. Ce principe que l’on doit à Toyota fait également référence aux machines capables de s’arrêter d’elles-mêmes en cas de problème.

 Juste-à-temps : méthode d’approvisionnement consistant à produire la quantité exacte demandée, au bon moment. Par extension, chaque poste impliqué dans le processus de production fournit ou produit uniquement les pièces nécessaires.

 Takt time : issu de l’allemand taktzeit, ce concept permet à l’organisation de définir une cadence de production idéale en se basant sur la demande de ses clients et de la saisonnalité. Le takt time correspond plus exactement à l’unité de temps requise pour livrer un produit à un client.

Six Sigma For Dummies Cheat Sheet

Six Sigma For Dummies Cheat Sheet | Devops for Growth | Scoop.it
To apply Six Sigma to your business and produce the best results, you need to understand what Six Sigma is, the principles of Six Sigma, and the DMAIC problem-solving method. The correct tools and use of the Six Sigma scale and methods will keep your data dependable and reusable.
Mickael Ruau's insight:

Six Sigma Principles

Six Sigma is based on a handful of basic principles, and these principles create the entire Six Sigma arrangement. Here are Six Sigma’s fundamental principles:

  • Y=f(X) + ε: All outcomes and results (theY) are determined by inputs (theXs) with some degree of uncertainty (å).

  • To change or improve results (the Y), you have to focus on the inputs (theXs), modify them, and control them.

  • Variation is everywhere, and it degrades consistent, good performance. Your job is to find it and minimize it!

  • Valid measurements and data are required foundations for consistent, breakthrough improvement.

  • Only a critical few inputs have significant effect on the output. Concentrate on the critical few.

  • Every decision and conclusion has risk (ε), which must be weighed against the context of the decision.

Many companies have a major opportunity to optimize efficiency and minimize waste in the development of their software using lean software development practices, yet many have simply not discovered the methodology. For those who have attempted to adopt this concept, most discussions and literature don’t provide specific, easy-to-follow practices for implementing lean software development. This Refcard fills the gap by covering a step-by-step approach to carrying out a lean software development process, including best practices to streamline your technology value stream.

Agile Tour Rennes - Atelier découverte des Toyota Kata

Un des piliers du fonctionnement efficace d’une équipe agile est l’amélioration continue. On pense alors recueil de feedbacks, organisation de rétrospectives, suivi de plans d’actions, etc.

Mais pourquoi attendre la rétrospective et son plan d’actions mis à jour pour améliorer une pratique ? Comment passer à la vitesse supérieure ? Comment passer d’une démarche soutenue par une méthode à une culture de l’amélioration continue ?

Les Toyota Kata, formalisés par Mike Rother, peuvent vous aider. Ces Kata sont des routines structurées qui incitent les personnes à développer une activité d’amélioration par la résolution de problème quotidienne et non plus périodique, réalisée par tous et dont l’objectif n’est plus l’élimination des sources de gaspillage mais l’atteinte d’objectifs stratégiques ambitieux.

Venez expérimenter les principes du “Improvement Kata Exercise” via un atelier accessible même aux enfants visant à développer :

- La pensée scientifique et créative afin de générer et affiner des solutions aux obstacles grâce à l'expérimentation.
- La collaboration : travail en équipe pour atteindre un prochain objectif sur la voie d'un défi plus ambitieux.
- La communication : organisez vos idées, vos données et les résultats et partagez-les efficacement.

Multi-Vari Study, Multi-Vari Charts

Multi-Vari Study, Multi-Vari Charts | Devops for Growth | Scoop.it
The multivari tool shows you variation (the enemy!!!) by separating it into three possible sources (within-piece, piece-to-piece, and time-to-time.)
Mickael Ruau's insight:

Multi-vari vs other chart types

Stem and leaf chartshistograms, and frequency distributions are all snapshots of process variation. They can’t help you to figure out the source of that variation. Multi-vari charts, though, can. 

Recap of variation sources

  • Within piece: variations within a single instance of a product. Also known as positional variation.
  • Piece to piece: variations that occur between different instances of the same product. Also known as cyclical variation.
  • Time to time: variations that occur at different production times. Also known as temporal variation.

Generate Clues with Multi-vari Charts. This technique is especially well suited for analyzing multiple sources of common-cause variation: within piece, piece to piece, time to time, and process stream to process stream.

Reducing Process Variation- Davis Bothe

Benefits of Using Multi-Vari Charts

A multi-vari chart can:

  • Show most of your variations.
  • Assist you in breaking down the components of variation.
  • Show all measurements recorded.
