ScrumButs transitoires

ScrumButs assumés

Nous u1lisons Scrum, mais

nous avons besoin d’une grosse équipe pour avoir toutes les compétences indispensables au projet.

Ainsi nos équipes sont + nombreuses que les 9 personnes recommandées.

ScrumBut

We use Scrum, but

having a Daily Scrum every day is too much overead,

so we only have one per week.

ScrumBut

We use Scrum, but

Retrospec5ves are a waste of 1me,

so we don't do them.

ScrumBut

We use Scrum, but

we can't build a piece of func1onality in a month,

so our Sprints are 6 weeks long.

ScrumBut

We use Scrum, but

we have a list of bugs to fix,

we do two normal sprints and one bugfix sprint.

ScrumBut

Nous u1lisons Scrum, mais

des changements d'exigences doivent être prises en compte fréquemment,

aussi le périmètre du Sprint change en cours de Sprint.

ScrumBut

We do Scrum, but

we do not have anyone available to serve as a product owner

so we communicate by email, no ordered backlog

ScrumBut

We do Scrum, but

we cannot split our stories

so we cannot finish them in one sprint

ScrumBut

We do Scrum, but

hard precise deadlines are defined by management with hardened scope

so we just code

We do Scrum, but

we need to include/provide items from/to another team

so we just change the sprint dura5on from sprint to sprint

we do all our planning up front

ScrumBut

We do Scrum, but

we need extra-‐material to demo

so we demo items on our local environment and you cannot play with it

ScrumBut

We do Scrum, but

we are always saying the same things in our Retrospec5ves

so we don't do them anymore

ScrumBut

ScrumButs can come from many sources

• The business doesn’t want to be involved

• Everyone wants their features first and can’t agree on a priority

• Teams don’t know how to self-‐organize

• People aren’t available to work on teams full-‐1me

• Timeboxes arent adhered to

• Teams don’t see a need for a daily Scrum

• Teams can’t get a piece of func1onality done in one Sprint

• Teams don’t have the skills to “do” something

hGp://fr.slideshare.net/tangram77/scrum-‐buts-‐but-‐scrum

ScrumButs can come from many sources

• Teams can’t fit tes1ng into the same Sprint as development

• The Scrum Master tells the team what to do and how to do it

• Other managers can’t stay out of a Sprint

• Important things come up that require interrup1ng the Sprint

• The Sprints can’t start un1l all of the other groups do their up-‐ front work

• Other groups are building hardware or using waterfallhGp://fr.slideshare.net/tangram77/scrum-‐buts-‐but-‐scrum

“Each component within the framework serves a specific

purpose and is essen1al to Scrum’s success and usage.” —

Scrum Guide

"Les ScrumButs constituent les raisons qui empêchent de tirer parti de Scrum pour résoudre les problèmes et réaliser les bénéfices."

Ken Schwaber - Scrum.org

“Scrum is like chess.

You either play it as its rule

s state, or you don’t.”

K. Schwaber

http://agiletrail.com/2013/03/27/blasphemy-they-call-it-scrum/

You can’t call it Scrum if you’re not doing it by the book.

Scrum’s roles, artifacts, events, and rules are immutableand although implementing only parts of Scrum is

possible, the result is not Scrum. Scrum exists only in its entirety and functions well as a

container for other techniques, methodologies, andpractices.

• Do we really need a Scrum Master?

• Is it OK to have a part-‐1me Product Owner?

• Can we split people across Teams?

• Can we work on several projects at once?

• Can we have itera1ons for doing design and analysis?

Scrum deviations (2011)

Alors ?

Dévoiement de l'agilité ?

Adaptation agile ?mais

Names and what they refer to are important for

communication.

Si chacun utilise un autre nom pour sa déclinaison de Scrum,

comment va-t-on communiquer ?

ScrumBut= changer Scrum pour ne pas changer ?

Mike Cohn

"To me a ScrumBut is a devia1on from the minimal core set of Scrum prac1ces that is obviously a bad devia1on"

ScrumBut => Scrum mal appliqué => Scrum ne marche pas => L'agilité c'est nul

it’s waterfall with a few Scrum practices woven in.

Comment les ScrumButs transitoires ont-ils été

dépassés ?

De bons ScrumButs?

Jurgen Appelo

IMHO it is the perfect term for overzealous SM's who focus on process instead of people and agile values.

Jurgen Appelo

• The real op1mal method always depends on the team's structure and environment.

• In short: the op1mal method will always be an adapta1on...

• And that's what retrospec5ves are for!

Dennis Stevens

The goal is for the team to be able to iden1fy the capabili1es and outcomes that are most important to improving the teams delivery

Alan Atlas

my philosophy about scrum: do it well, give it a good try, but don’t kill yourself and if it’s not perfect, it’s s1ll good.

hGp://agileatlas.org/commentaries/ar1cle/what-‐scrum-‐means-‐to-‐me

Pragmatisme

Unless you are lucky enough to work for a company where top management supports Scrum, middle management also supports Scrum, and the whole company or IT department has been completely reorganized for Scrum, your project or company

environment may not be as perfect as Scrum prescribes.Scrum In Action, chap. 12

http://www.amazon.com/Scrum-Action-Andrew-Pham/dp/143545913X

Church volunteers had their daily stand up only once every Friday when they came to church because they

did not come to the church every day.Arline C. Sutherland "Scrum in the Church"

“Individuals and interactions over processes and tools”http://en.wikipedia.org/wiki/Cargo_cult

ButScrum• But Scrum says we es1mate

–I have personally been around agile teams that dont es1mate all of their items in their backlog. Why? Mul1tudes of reasons.

• A couple of examples: –Teams break down their work far enough (day range) where the variance in the es1mates would be minuscule.

–A team works really well together and can accurately predict how much they can get done, without worrying about points

Les bons et les méchants ?

Positive ScrumButsThey make a team's performance better.

AdaptationExperimentation

Innovation

(Positive). Good adaptation of Scrum that helps get the team moving forward despite some constraints they

have to deal with in the real world.

An example for a good deviation is the replacement of the Daily Scrum with a standup every 1.5 hours, because all of the intentions behind the original element are still (and even better!) met with the use of the new element.

http://agiletrail.com/2013/03/27/blasphemy-they-call-it-scrum/52

Negative ScrumButsThey make a team's performance worse.

Bad excusesWrong application

The deviation is bad, when one or more of the intentions behind the original element are not met anymore.

For example, replacing a single person PO by a PO board is a bad deviation, because one of the intentions behind the original element (fast decision making) are not met anymore.

Comment discriminer ?

a “C” if it is caused by Scrum (in other words, without Scrum it would not be

happening), or an “E” if it is exposed by Scrum

(in other words, it would be happening with or without Scrum, but Scrum makes it known to the Team),

or a “U” if it’s unrelated to Scrum (like the weather).

http://jeffsutherland.com/ScrumPapers.pdf

• Pourquoi cette règle Scrum ?

• Ken Schwaber expose un principe

• Quels sont les risques à ne pas la suivre ?

• Ken Schwaber utilise le mot Conséquence

Scrum is making problems visible and requires you to

change your behavior and way of thinking

Ken Schwaber http://www.youtube.com/watch?v=tgBkvS-q_fA&lr=1

http://www.youtube.com/watch?v=-MZdKaqY6wU&lr=1

what (approach)

why (purpose/intent)

who (is involved and to what extent, RACI is a good model for this)

when (how often, how does the time impact other elements)

how (does it feel when it is working right versus working poorly)

http://agileforest.com/2013/03/29/scrum-intentions-scrumbut-scrumand-and-shu-ha-ri/

http://racichart.org/

http://commons.wikimedia.org/wiki/File:RACI_Matrix.png

The RACI Matrix shows responsibilities for a task or set of deliverables (i.e. who is Responsible for doing the work; who will beAccounted for it; who will be Consulted for it; and who will be Informed

once it has been completed).

Do Retrospective!

Whatever they want to change, I never allow them to drop retrospec1ves and analyze with them what happened aver they altered something

Escalader

Les ScrumButs sont des signaux d'obstacles organisa1onnels.

Ken Schwaber conseille de créer une équipe dédiée pour les traiter : Enterprise Transi5on Team.

Son objec1f est de supprimer les obstacles remontés par les équipes Scrum.

Étude de cas

• Our Product Owner is an arrogant son of none who won't listen to anyone and who pushes everyone around. Our retrospec1ves just wind up with the PO shou1ng at everyone and forcing the same outcome every 1me, work harder and quit whining.

• It is s1ll Scrum if we exclude the Product Owner from our Sprint Retrospec1ves?

Ron Jeffries: hGp://agileatlas.org/commentaries/ar1cle/is-‐it-‐s1ll-‐scrum-‐if

• What is the rule?

• What is the goal of the rule?

• What is the organiza1on issue?

• What is the risk of breaking the rule?

• How can we s1ll target the goal?

Yes, the Product Owner needs to be in the Sprint Retrospective or you're not doing Scrum.

• What is the rule?

–Sprint Retrospec1ve is for the whole Scrum Team

• What is the goal of the rule?

–best results come from 1ght connec1on between Product Owner and Dev Team, with true collabora1on and coopera1on.

–"Business people and developers must work together daily throughout the project."

–"At regular intervals, the team reflects on how to become more effec?ve, then tunes and adjusts its behavior accordingly."

• What is the organiza1on issue?

–Command-‐and-‐control paGern, no full understanding of Scrum…

• What is the risk of breaking the rule?

–No Working Retrospec?ve

How can we still target the goal?

• SM teaches the PO

• Get a # PO

• new mee1ng Dev Retrospec1ve without PO
