Inherited Task board

Retrospective : DONE Definition

DONE Definition

QA was a bottleneckhttps://www.flickr.com/photos/technicool/

Solution

Limit

WorkIn Progress

Limit the WIP

Problem 2 : Envisioning is the bottleneck

Next change :

Merge Envisioning/Design & Realisation

Problem 3 : Non push <> pull system

Pull from the needhttps://www.flickr.com/photos/poppywright/

Pull System

Thinking Furtherhttps://www.flickr.com/photos/desiitaly/

Non Stories - Doesn’t fit

Stories well defined goes quickly https://www.flickr.com/photos/adabo/

Unclear Items are slow

Response: Big picture

Learning

Reflect against your Kanban

Chapter III : The Retrospectives

starting point : open a space and provide toolshttps://www.flickr.com/photos/philgyford/

in social housing ...

From outsidehttps://www.flickr.com/photos/alexanderwithers

Co-Sensing

To insidehttps://www.flickr.com/photos/imagezen

Co-construct shared knowledge from the insidehttps://www.flickr.com/photos/booleansplit

Start by appropriating the stories

The global process: play with the business

The global process: a guideline

What I learned

The knowledge comes from the inside, not from the outside.

Shared knowledge may improve autonomy, initiative and creativity.

Testing AproachThe research of the quality

Fixed Price

Fixed Scope

Flexibility

Fixed Date

It will be a long road

High quality is the only way

https://www.flickr.com/photos/lafiebredeloro/

Let’s try something : BDDhttps://www.flickr.com/photos/imipolexg/

Adaptation : Remote Steps

https://www.flickr.com/photos/heycoach/

Test API is good

https://www.flickr.com/photos/90155419@N00/

BDD is very useful in Demo

https://www.flickr.com/photos/plasticbag/

Very useful to define DONEhttps://www.flickr.com/photos/comedynose/

But didn’t worked for us as support for discussionhttps://www.flickr.com/photos/jirka_matousek/

Useful for regression test and bug fixinghttps://www.flickr.com/photos/coofdy/

Two levels of testing

Junit + JMock=> Quick feed back=> Design Feed-back

Unit Test

But it is hard with complex data !

https://www.flickr.com/photos/pittou2/

Testing dataUse Builders, with Chain of methods

reg = aRegistration().of(aNonEU()).excluded(lastYear()).value();

Conclusions

Quality is Free(in some context)
