The short answer: it depends. The number of specialists in the dedicated development team is defined by the features you want to implement and their complexity. However, the standard team who will create software as a service for you will include the following specialists: a business analyst who will explore your SaaS business idea and your business requirements, and a software development team lead who will create user stories and offer technical solutions for potential bottlenecks. Also, you will need a UX/UI designer who will show you how your application will look and function. The back-end and front-end developers will build the server-side and graphic interfaces. Quality assurance engineers will test your software to ensure it works properly and does not have any bugs. Finally, you will need a project manager to work between you and the development team. This specialist will keep you updated about the current state of your SaaS development project.
