Functional and Non-Functional Requirements for Ecommerce Website

They say successful businesses begin with an idea. We say they all begin with functional and non-functional requirements for ecommerce websites.

Functional and non-functional requirements are the pillar of your project. They articulate your needs and wishes and specify the tasks for your development team. You can start writing them down soon after issuing your ecommerce RFP to have a clear picture of your website by the time you choose a vendor.

All of our projects at Elogic start with a brief clarifying the client’s functional and non-functional requirements for the online shopping project. Unless a client sends a list directly to us, we issue a document for them to fill out (see it as a downloadable bonus at the end of the article!). This way, we’re sure that we understand their business needs, while the client can adjust the project budget and scope and deliver positive online shopping experiences on the website.

In this article, we’ll explain the difference between the functional and non-functional requirements for online shopping systems and present a list of the most common ones based on our clients’ real-life examples. We’ll also share some tips on how to organize the requirements and what they should look like.
