Agile teams deliver continuously

See the original posting on DZone Python

Agile teams deliver
continuously. Which means;
Code
must be integrated continuously 
Code
must be tested continuously
Each story is
integrated to the master or develop branch once competed. Ideally small code
increments are integrated to master/develop as progress is made within a
story. Each story is tested
immediately. First with unit tests, then with integration tests…

On Setting Your Initial WIP Limits

See the original posting on DZone Python

During a recent training course, I was asked how their team should calculate the initial WIP limits for a team starting out with Kanban. Now, the correct answer is that you need to experiment; find the WIP limit that is low enough to identify bottlenecks & promote a smooth flow, but is still high enough not to artificially create bottlenecks. This answer is all well & good to refine the…

Who Removes Your Obstacles?

See the original posting on DZone Python

In self-organizing teams, teams remove their own obstacles. It’s a good idea. It can be difficult in practice.

In Scrum, the Scrum Master is supposed to facilitate removing the team’s obstacles that the team can’t remove. It’s a good idea. It can be difficult in practice.

Geek Reading December 1, 2014

See the original posting on DZone Python

I have talked about human filters and my plan for digital curation. These items are the fruits of those ideas, the items I deemed worthy from my daily reading. These items are a combination of tech business news, development news and programming tools and techniques. You will note that some of the formatting has changed, and that is due to the change in my process.

Data Science workshop at data2day

See the original posting on DZone Python

Giving a one day tutorial on data science is something I’ve been considering in different contexts from time to time, but for different reasons it never really happened. Finally, last Friday, the tutorial took place as a workshop in the data2day conference, and I think it went pretty well. In this post I’d like to talk a bit about our approach and our experiences.

Don’t Give Partial Credit

See the original posting on DZone Python

What do you do with stories that don’t finish before the end of the sprint? Do we get partial credit?

I’m asked that a lot. Everyone wants to know whether to split the story and what to do with the points. Don’t give partial credit for unfinished stories or make untestable splits.
Don’t Bother Splitting Unfinished, Untestable Stories

Move unfinished, untested stories to the next…

Creating a Budget and Sticking to It

See the original posting on DZone Python

The hardest part of doing anything is starting. If you’re someone who has delayed getting serious about retirement savings, or budgeting in general, I would encourage you to simply begin, today. I’ll describe my personal budgeting system, not because I think it’s the best system, but because it’s a place you can start if you’re not sure where to begin.

The New Agile: The Beginning

See the original posting on DZone Python

Frequent readers of this blog know I’m a big proponent of agile, with a small ”a”. I tend to scoff at new big ideas that seem to jump out of a marketing committee.

Truth is, sometimes these are good ideas. Sometimes they are first versions of trials and errors. When we look at them at the current stage they may seem ridiculous, but if someone get exposed to them, and continues the push,…

Comparing Strikers Statistics

See the original posting on DZone Python

Here we compare the scoring statistics of four of the best strikers of the recent football history: Del Piero, Trezeguet, Ronaldo and Vieri. The statistics that we will look at are the scoring trajectory, scoring rate and number of appearances.

To compute these values we need to scrape the career statistics (number of goals and appearances per season) on the Wikipedia pages of the players:

What is Product Management?

See the original posting on DZone Python

I often get asked what it takes to be an effective product manager or product owner, which product skills the individuals should have, and how a company can strengthen its product management function. Answering these questions requires an understanding of what effective product management looks like in the digital age.

Developing a billing system with Django

See the original posting on DZone Python

In the development of most services there is a need in the internal billing for service accounts. Our service (http://bitcalm.com) also had such a problem. We were not able to find ready-made packages for its solution and in the end had to develop a billing system from scratch.In this article I want to talk about our experiences and pitfalls encountered during development.

Visualization of probabilistic forecasts

See the original posting on DZone Python

This week my research group dis­cussed Adrian Raftery’s recent paper on “Use and Com­mu­ni­ca­tion of Prob­a­bilis­tic Fore­casts” which pro­vides a fas­ci­nat­ing but brief sur­vey of some of his work on mod­el­ling and com­mu­ni­cat­ing uncer­tain futures. Coin­ci­den­tally, today I was also sent a copy of David Spiegelhalter’s paper on…
