After continuous integration there is continuous validation

It’s a funny thing to say that delivering business value is the most important thing when developing software. It doesn’t matter that a framework like Scrum is far from efficient, because we focus on value. We deliver business value. Working software. Every sprint. Period. But in the end we often just don’t know the impact …

How assumptions are not the mother of all f-ups

The thing about trends is that they will come and they will go. So after the agile trend continuous delivery and devops are in line. I think in a way it is very nice to see that development craftsmanship practices are becoming more and more accepted. We can all benefit from this. Software is eating …

Bring home the bacon not the receipt

When did we start to lose track of what we really needed and began focussing on how much something costs? As a Scrum Coach I see it more than often that customers ask how much time something takes. How much effort and money is needed. The planning of a project is build upon the time …

DevOps, building on quicksand?

The management decides they want DevOps and Continuous Delivery. It is faster, cheaper and there are less people needed for the same work. So now DevOps and CD are set as goal for the whole company to reach in the near future. So basically engineering practices are being set as strategy, top down. DevOps is …

The myth of estimation

One of the trickiest parts in Scrum is estimating the entire Product Backlog. Often I’m asked to do this or to help Product Owners to do so. In almost every case management, the CEO or the customer demands it. Why would they want this? They want to know when everything is finished. And by estimating …

Functional agility vs. technical solidity

Scrum is about delivering value to the business right now and being agile when it comes to future wishes. Software architecture is about being prepared for the future. Those two don’t seem to match very well. Well, agile does not mean ignorant, and prepared does not mean ¨cast in concrete¨. So start doing, and never …

Why so serious?

It’s all about the input

Garbage in, garbage out This is a pretty basic principle. But what do you expect? What are the odds that if you give poor descriptions of your vision and needs that the results will be as expected? 50/50? Maybe less? Within the agile community there’s a lot of information to be found on processes and …

You’re doing it wrong

Wrong way Scrum

I often encounter people who use Scrum according to their opinion as it is supposed to be done but when I ask certain questions it seems they are not doing it at all. I often wonder why that is. Scrum isn’t so difficult but in order to get it to work it is important to …

People are not cattle

It is impossible to predict the future. So why do some of us still try to bring their company into jeopardy in trying to do so. I think we all heard of top managers who think they have so much experience that they can read minds, bring success to projects by keep doing the same …
