Web part is an individual module that can be placed on the intranet main page as additional elements or tabs. They complement the SharePoint with functions that were not provided in the basic version of the platform.
How does it look in practice? Let’s say that Mr. X uses SharePoint daily. The platform meets its requirements and helps to perform duties. Mr. X, however, spends a lot of time to send documents to company partners and clients from SharePoint libraries. He would like to use a tool that would enable it.
And that is web part: a solution which could be installed as part of SharePoint. You can choose from ready-to-install tools or commission a software house to create web part completely tailored to the company’s needs, but it is important that the solution is integrated with the platform and allows you to work in the best way for the company.
