Support in requirements engineering for a quote calculation system

The application enables users to calculate quotes for several customers and analyzers of different diagnostic areas. A central module is the determination of materials (reagents, controls, calibrators and consumables) required in the customer's laboratory, with all necessary quantities. Users can adapt these in the quote. New diagnostic analyzers and tests, chemicals, pack sizes and calculation algorithms are continuously integrated in the process. Another module is the determination of prices and discounts for single materials and boxes of multiple materials. Users can adjust these in the quote. New price models (e.g. for subscriptions) and options are continuously integrated in the process. To integrate the calculation of quotes into the IT environment, existing interfaces are converted to communicate with the Mulesoft API and new interfaces, which uses this API as well, are implemented.
