My product development approach is based on the principles of "design thinking" and "agile software development", which ensure a collaborative and iterative approach and the continuous delivery of new features to customers through close collaboration and direct feedback. The business model will continue to be tested and refined according to the principles of "design thinking" in five main phases. The two initial phases of "Empathize" and "Define" are combined and focus on understanding the customer, the defined "Personas", "Customer Journey" and the validation of hypotheses with experiments such as customer interviews. The next phase, "Ideation", focuses on the further development of the product concept and business model as well as the development of new features based on customer feedback. The last two phases, "Prototype" and "Test", focus on creating a "backlog" of future features based on customer feedback, then developing and testing new features and refining the current product. The software development is based on the principles of "agile software development", which guarantees the continuous provision of new features to solve the most important problems of customers. We apply product development cycle of "Build-Measure-Learn" to ensure a scientific and iterative approach to implementation. The development team works in "sprints" using models and methods such as "Scrum" and "Kanban" to prioritize work. A "backlog" is created for collecting requirements and according to the evolving needs. For each new function, there will be a test phase for pilot customers with subsequent recording of customer feedback.
