A number of my colleagues and myself recently decided to share our knowledge regarding “performance” on this medium. You are now reading the first blog in a series in which I present a test-driven approach to ensuring proper performance when we deliver our project.

Test driven

First of all note that “test-driven” is (or should be common in the java coding world. It is, however, applied to the unit-test level only: one writes a unit test that shows a particular feature is not (properly) implemented yet. The test result is “red”. Then one writes the code that “fixes” the test, so now the test succeeds and shows “green”. Finally, one looks at the code and “refactors” the code to ensure aspects like maintainability and readability are met. This software development approach is known as “test driven development” and is sometimes also referred to as “red-green-refactor”. Read more

This Blog is a kick off to for many writings about architecture in an Agile World. We will explore the topic from all the views possible, in order to gain a better understanding about it. By doing so, we hope to create a community of followers, who would also like to contribute or discuss about this topic.

Xebia is helping many organizations in the Netherlands, France, the United States and India with implementing an agile way of system development. In most of the cases the Scrum method is applied and very good results are achieved. Business and IT are working much closer together, resulting in more quality and much more customer satisfaction. However, lately we also see a trend in problems that seem to occur in (almost) every organization. Software is developed in a fast way with high quality, but it takes forever to get it in production. The more teams are being formed, the more interdependencies between the teams occur Read more

This is the eleventh and last post in a series of blog posts discussing Lean Architecture principles. Each post discusses one principle. Applying these principles results in an architecture (process) that is better connected to the business, better able to deal with change and more cohesive. The eleventh principle we discuss is called “Freedom where possible, standardize where needed“. Read more
