But also in a management role I value focus time a lot for strategic work, research, analysis, and sometimes even just to be able to process all input and reflect on what the current state and bigger picture are. How to achieve this and combine this with nobody being blocked because of missing information in remote environments?

When you are beginning to consider refactoring your big legacy codebase towards a new software design, then it is not uncommon to feel helpless after estimating this to be a huge terrifying 2-5 years project. To help solve the problem of not knowing where and how to begin, we have had great success using a decision matrix to decide how each part of the legacy code should be changed in such a refactoring project.

Checklist For A Reliable Load-Test
Setting up a load-test that produces results you can rely on is not that simple. But without realistic test-results you cannot be sure that your application handles sudden increases of traffic, rapid spikes or even the initial go-live. And you cannot estimate at which number of users you should scale up your hardware. Both details are very important to keep the application running at all times and guarantee that no revenue or developer sleep is lost because of outages. We have a large checklist of points we go through when setting up performance tests with customers and I wanted to discuss some of the more important points in this blog post.

Refactoring with the Advanced Boy Scout Rule
When we join teams to coach them with refactoring their legacy code base, many of them are overwhelmed by the sheer mass of code. That typically results in the request for "some refactoring sprints" or even "a complete rewrite". Both is obviously not a solution from the business perspective - feature development and bug fixing needs to go on and the refactoring should not eat up the larges portion of time. But where and how should the team start and how should? What we call the "Advanced Boy Scout Rule" has helped many teams to come over this staleness and reach fast results while continuing to deliver business value.
