High-performance IT delivery models

High-performance IT delivery is an approach that enables cross-functional teams to continuously improve the products, process and people that are required to deliver value to the end users. If there is no continuous feedback about quality and risks, the development approach cannot be seriously called iterative, because the result of an iteration is only shippable if the stakeholders can establish their confidence based on proper information.

In this section two high-performance IT delivery models will be explained in more detail: DevOps and Scrum.

High-performance IT delivery models.

Other "models" that we have also classified under high-performance IT delivery are Lean, Agile, Kanban and Spotify, which doesn't mean you cannot use these "models" in other IT delivery models. Based on our experiences, we see that the meaning of these models and possible relationships between these models are not equally clear to everyone. For this reason, a brief overview is presented on how we regard these models in the section "Other high-performance IT delivery 'models'".

  • lightweight
  • simple to understand
  • difficult to master.
