The software development process for the development of a certain ecommerce system is defined by a process model. A process model presents all the activities in a certain order, the required tools and the created intermediate or final products that are necessary to achieve the goal of the process.

Interim’s process model is tailored to each particular project and hence it is more concrete than a generic practice model. A formal description of a eCommerce development process in the form of a process model simplifies its support by automatic systems, it is not mandatory just a structured and comprehensive description can be sufficient. We don’t blindly follow best practices formulated by reputable quality standards organization but use our experience and common sense as most standards define only the contents of the description of best practices and development guidelines, but not their notation.

The object-oriented design, the implementation of adaptors to integrate software systems as subsystems of the electronic commerce portal using the ASP/Java programming language, and the use of a middleware for communication within the portal are represented in this software development process.
