ManageIQ is an open-source management platform that delivers insight, control, and automation functionality allowing enterprises to manage hybrid IT environments. The ManageIQ application collects information about various entities such as Virtual Machines, Hosts, Containers, etc., with numerous attributes and relationships. ManageIQ is a very complex application, and therefore the student will focus on a filtering component. Filtering is a very common task in IT and most applications allow users to carry out filtering and searching. Some applications allow a simple text search, other use more complex filtering and search tools. ManageIQ contains a filtering facility called "Expression Editor". It allows the users to create complex filtering expressions using properties and relations of the items being filtered. Currently, the filter component is a very powerful tool in terms of its functionality, but it has poor usability. The time and effort needed to create a filter is great since the expression editor is not very intuitive. The first part of the work is expected to focus on research regarding usability of web applications. The paper will look for possible approaches, best practices and guidelines for designing usable web applications. The student will then analyze the current solution, its interactions, capabilities, use cases, and identify its usability problems. Then the student will look at existing solutions with similar problems used in other products and analyze and compare them to our solution. Based on this research, the student will design a new solution that should be more usable and intuitive without restricting user capabilities. The paper will cover the solution and the processes employed during its creation. As a final step, the student will implement the solution as a reusable component with up-to-date web technologies. The final result of the practical part of the work will be a pull-request against the ManageIQ repository on Github.
