My Software Process

A transparent and efficient process that gives you maximum control and flexibility.

Phase 1

Requirements

In an initial meeting we discuss your requirements and develop a tailor-made concept together. Your wishes and preferences are at the center of this process.

Phase 2

Proposal & Planning

After the concept phase, you receive a non-binding offer along with a professional service contract. Upon your approval, I create a detailed project plan with clear milestones.

Phase 3

Agile Development

Development follows an iterative process of design, feedback and implementation. You can continuously test the product and change requests are usually possible.

Phase 4

Hosting & Support

After completion, if you take the software care package, I handle the complete deployment of your software and the continuous improvement of your product.
