Software quality: economics of formality
Posted by jpluimers on 2019/11/06
Interesting read: [WayBack] Software quality: economics of formality
At one time formal methods were thought to be the only hope for software development. That did not turn out to be the case.
Via: [WayBack] Software quality is better in practice than in theory. Formal methods improve software quality, but at a high cost that is sometimes worthwhile and some… – Jeroen Wiert Pluimers – Google+
Comment there:
+Jeroen Wiert Pluimers +John Cook , I think that when a code has been in service for even a short time, we can divide the code into two classes. The first is that part that has been executed at least once. The other code has never been executed. The latter code has an error rate that may be measured as a function of the language used. In the old days Fortean had a bug in every seven lines. C used to be 100 to 200 lines. We set up instrumentation to determine the number of lines tested in the first class and found that it was a linear function of the new bugs found. This was a good way to ensure a high quality code.

Meeting Ticker – the real cost of a meeting visualised
Posted by jpluimers on 2019/11/04
Ever figured out how costly meetings are?
Show the [WayBack] Meeting Ticker during a meeting and be amazed after filling in just a few fields:
Of course it is open source: github/tobytripp/meeting-ticker
And I also found who originally referred me to it: [WayBack] Weekend Reader 2017.48 – reality-loop

Interesting that the world at large found out about the 1980s Pomodoro Technique:

She refers to [WayBack] The Busier You Are, the More You Need Mindfulness which states You can get benefits in as little as two minutes.

Sprints, marathons and root canals and Brady Printed Lean Labels – for lean development
Posted by jpluimers on 2019/10/15
Apart from blank and custom labels, Brady also sells [WayBack] Brady Printed Lean Labels | BradyID.com
They work great for agile projects, despite marketed as “will help you improve reliability, up-time, and efficiency”.
I found them via:
which led me to [WayBack] Sprints, marathons and root canals, which is a long but recommended read.
That got me to a book that is now on my reading list: [WayBack] James Shore: Agile-Book, especially this chapter:
[WayBack] James Shore: The Art of Agile Development: Iteration Planning
Assorted sets of stickers are (all in packs of 10 each):
[WayBack] Brady Part: 110763 | Assorted Reliability Stickers
Though you can also get them individually in 10 packs:

“Real Options” Underlie Agile Practices
Posted by jpluimers on 2019/10/09
On my reading list: [WayBack] “Real Options” Underlie Agile Practices
Whether we realise it or not, “freedom to choose” is a principle underlying many Agile practices. By avoiding early commitments, we gain flexibility in the choices we make later. In this article, Chris Matts and Olav Maassen propose that an understanding of “Real Options” allows us to develop and refine new agile practices and take agile in directions it hasn’t gone before.

28 Product Backlog and Refinement Anti-Patterns – Agile Transition
Posted by jpluimers on 2019/09/23
Food for thought: [WayBack] 28 Product Backlog and Refinement Anti-Patterns – Agile Transition
The most important one I learned: keep 20% slack and 20% technical debt+bugs (on a legacy system even more of the latter). This sounds like 40% waste, but is in effect a huge win as it makes the team much more flexible in responding to spikes, supporting team-mates (or cross functional teams) or having an off-day.
