“However beautiful the strategy, you should occasionally look at the results.”
Winston Churchill

“This is your throughput this week Son, what’s gone wrong?”

“Nothing Dad, I just didn’t feel like doing anything.”

“Ok, but what if no one here felt like doing anything….”

“No idea…”

“Come on, don’t fool me around, you know the whole housesold would collapse”

“Don’t think so, Mom and you would fix it.”

“Nope, I mean if NO ONE here felt like doing anything, including Mom and me….”

“You can shift some of last weeks’ cards to this week, can’t you? So my through…how-do-you-call-it would be ok for this week as well, score done!”

“It’ not about a making a score, Son, it’s about doing something to collaborate with the community you live in. That’s the objective.”

“Isn’t it about the score…”

“No it isn’t. Just making the score is called ‘vanity metric’.”

“I am not vain.”

“I’m not saying you are vain, I’m saying that focusing on the score, and not on the underlying event measured by the score, ends up being a vanity metric.”

“Again your nerdish kanban thing, Dad….”

“Yes of course, Son, but let’s go back to the point: are you going to do something for the community this week, or not?”

“If I should….”

“Yes please.”

Addressing teenagers’ “Why me?!?” syndrome with Kanban

March 29th, 2024 by

“It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.” – Mark Twain

“Can you please help?” asks Dad to Son

“Why me?!?” answers Son

“Because we live together and any of us helps a bit, it’s called collaboration”

“But I do help a lot already!”

“Nope”

“Yes!”

“Well… not so much”

“YES!”

“All right Son, let’s do something about it!”

After some while the first simple Kanban board appears in the kitchen. Three columns: ‘to do’, ‘in progress’ and ‘done’, very simple one. Anyone has their own coloured pin: blue Mom, yellow Dad, green Son, red his Brother. And the first metric appears. Cards count: very simple one.

“I’m stuck!” says one day Dad to Mom

“I’m too busy!” replies Mom to Dad

“….but you are idle!” goes on Dad pointing to Son

“Me?” bounces back Son

“Yes! You ain’t that busy are you?”

“What the…. uh, but actually I’m busy …. uh… busy doing…”

“…doing what Son? There isn’t any card under your pin ‘in progress'”

“Yes, but I always do a lot!”

“Let me check your throughput…”

“My through…what Dad?!? You’re still the same old nerd…”

“Your throughput Son, which is the count of the cards which have been processed by you… actually over the past week you don’t seem to have done much, in fact your brother’s card count is four times than yours, let alone mine and Mom’s which are much bigger as they should be. You don’t want to end up looking the laziest in town, do you?”

“No, no, definitely not!”

“All right then, may I ask for your help please?”

“Ok, ok, but… but…”

“But… what?”

“Nothing Dad, doesn’t matter”

Conversation between a (Kanban Coach) father and a teenage son

February 28th, 2024 by

“A problem well stated is a problem half solved.” – Charles F. Kettering

“Today I’ve been called from school and told you are always late….”
“Me?! What the…. I mean, not ALWAYS… from time to time maybe yes, but not always, in fact I’m very often on time!”

“All right Son, let’s do something about it!”

A few months later, showing a chart displaying the statistical distribution of delays.


Statistical distribution of delays

“Son, this is the metric of how often you are on time or late, overall”

“Who? Me? You must be joking!”

“No, I’m not, this is you over the past months, as you can see your on-time-arrival rate is 68% of occurrences, whilst you arrive within 15 minutes of delay 93% of times and 99% of times your are there within half an hour of delay, that is it”

“Dad you are a damn nerd!”

“Yes, I know I am Son, but these are facts, what the psychologists would call a reality check. Which is the rate of delays that the school is ready to accept?”

“No idea Dad”

“All right, then check with them, even though I suspect they have an expectation that is much lower than your current delay rate; by the way the good news is that the statistical distribution is reasonably thin tailed which means that you are consistently predictible…”

“What is this statistical crap Daaad?! Tell me in a way that also the cat can understand!”

“I mean that you do things more or less always the same way, so probably it’s enough that you set an half an hour earlier your alarm in the morning and you will be consistently on time, if you want….”

“Come on Dad, why should I wake up half an hour earlier…. I can instead rush and be on time!”

“It’s your decision Son, you are the master of your fate, your are the captain of your soul….”

“Also the poem crap now, stop it there Dad, got the message….”

Scrum applicato in azienda: ridurre il carico del team per aumentarne l’efficienza

January 11th, 2022 by

Un team agile, come qualunque sistema di servizio, raggiunge la massima efficienza se non viene caricato oltre i due terzi della propria capacità massima. Un concetto controintuitivo che ci viene spiegato dalla teoria delle code.

Scrum applicato in azienda: scrivere i requisiti in un progetto agile

Mi viene sempre chiesto quale contratto fare per progetti che utilizzano la metodologia Scrum: in questo video provo a dare una risposta a questo quesito.

In questo video ho fatto qualche esempio di planning poker, lo strumento più usato in scrum per fare le stime per analogia attraverso gli story point. Nel video ho utilizzato le carte da planning poker di Praxis Framework, che ringrazio.

Uno dei concetti meno compresi e forse per questo meno applicati, ma secondo me utili quando si lavora in modalità agile.
