Modern intranets need to work both ways. There are no questions about it. Employees should be enabled not only to search for and retrieve information but also to share it and get things done. Intranets have to support business processes.
The most straightforward example is creating tickets or issues, for IT matters and also for any other purpose like requesting a graphic design, updating a web page, or helping with legal documents, translations, etc.
All those options need interactive forms with validation, and a means to assign people or teams to it, set a priority, status, and support further communication in case of questions.
Often, file-sharing is also needed to make it possible to get things done in one place without using separate shared drives (“I have no access to that drive”) or sending files via email (“the file is too big”).
Many companies also provide a feedback form to measure the quality of the work results provided by a given team. Collecting such feedback also needs to be appropriately designed and generate meaningful reports.
Another excellent example of a modern facility many companies implement in their intranets is “360 Degree Feedback” where employees receive valuable anonymous feedback from the people they work with - their managers, peers, and direct reports.
