Slack is to your organization as sleep is to your body

October 17, 2013 12:48 am

This is just to collect a few thoughts I had on June 28, 2013 to make them easier to find and refer to. This tweet started it: https://twitter.com/GeekTieGuy/statuses/350639064703176705

Here is what the next few tweets summarized:

Slack is to your organization as sleep is to your body: time to regenerate and be inspired by dreams and wake with new energy.

What happens when we deprive the body of sleep? We become manic, disoriented. We diminish our capability to be creative, we go insane.

What happens when we deprive the organization of slack? It becomes reactive, haphazard, brittle, overloaded, unable to think.

I recently led a session at Agile Open California with this same title. It was interesting to a few people, and I was sure I’d blogged my expanding tweets, but I apparently hadn’t. Fixed that now…

A surprise in the 2013 Scrum Guide?

August 4, 2013 10:45 pm

I was looking at the updated 2013 Scrum Guide, and because of some questions that have come up at work, I looked at how much time the guide suggests as the upper limit for various Scrum meetings.

The four larger meetings look like this in the scrum guide:

Planning: 8 hours per month
Review: 4 hours per month
Retrospective: 3 hours per month
Refinement: no more than 10% of available capacity

That last one was a bit of a puzzler to me. How much would that be if expressed in hours, like the other meetings?

If we call “a month” 30 days, and each day 8 hours, we end up with 240 hours per month. Translating to percent of time we arrive at:

Planning: 3.33%
Review: 1.67%
Retrospective: 1.25%
Refinement: no more than 10% of available capacity

Turn that back into hours on a two week sprint (80 hours) and you get:

Planning: 2.67 hours
Review: 1.33 hours
Retrospective: 1 hour

And the kicker (after subtracting the three meetings above from 80 hours, leaving 75 hours):

Refinement: no more than 7.5 hours, assuming “ideal capacity”

This was a HUGE surprise to me. Actually a happy surprise! I’ve heard over and over from scrum teams I work with that clarity on what to build is the biggest problem they need to work on. So the good news is that the official Scrum Guide recognizes that it’s okay to spend up to 7.5 hours or so (in a two week “ideal” sprint) on refinement activities, which to me include improving clarity on what to build. I only wish it hadn’t been expressed in %-of-time.

The Scrum Guide of 2013 – Top 50 words

10:06 pm

I thought it would be fun to run the latest Scrum Guide through wordle.net to see what it talks about a lot. I replaced Scrum-specific terms that use two words in the guide to one word terms using CamelCase. Here’s what it looks like:

 

What do you make of it? I’m glad the word Retrospective shows up in the top 50, even if it is just barely.

Agile retrospectives – on cadence or on demand?

11:43 am

Here’s a quick thought for (probably mostly Ha- and Ri-level) practitioners of Agile software development who are thinking about holding retrospectives on a fixed cadence versus going to an on-demand practice.

I like that the weekend comes around every five days. I’d sure feel uncomfortable if it didn’t. I enjoy the comfort of knowing that I’ll get some time with different things to do: play, learn, relax, create, sleep, connect with others. Every once in a while I’ll need a day off outside the weekend to take care of exceptional things. Other times I’ll need more than just a few days, so I’ll take a week or three for a change of scenery and recharge.

Is it so different for teams at work? Just a thought.
