 In systems design, user analysis is the means by which scientists, engineers and technical writers determine the characteristics of users which will influence the development of software systems or other technological products. During the process, developers in technical fields gather information about users of their products though interviews, focus groups and other forms of qualitative research. This is typically performed by forming use cases based upon the actual workflow tasks which the users will perform while using that given piece of technology. Such analyses are vital to the composition of software documentation. Though very distinct, user analysis is related to task analysis. When developing new technology or software, identifying the potential users of a system and their attributes is necessary in order to ensure that said technology or software will be more user friendly. During this development, the user analysis is a basic research phase which takes place before actual drafting of the technology's technical documentation.In this way, it's typically the first step of the document composition process. Such an analysis is intended to result in tacit knowledge or a set of facts regarding the user's values, behaviors, knowledge of the documentation and product and motivation for using said documentation and product. Revealing the tacit knowledge of users' activities, as opposed to the simple operations which a given technology can perform, is often referred to as an unspoken but understood trick of the trade for the technical communicators who conduct user analyses. A good technical communicator will perform the user analysis aimed at finding both what exactly the user needs to do and what the user would do with the technology in question. Some experts in the field of user analysis have emphasized the importance of understanding the transfer of learning during this process, though the concept itself is a controversial one.
