End user
In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, information technology experts, software professionals and computer technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact easily overlooked and forgotten by designers: leading to features creating low customer satisfaction. In information technology, end users are not "customers" in the usual sense—they are typically employees  of the customer. For example, if a large retail corporation buys a software package for its employees to use, even though the large retail corporation was the "customer" which purchased the software, the end users are the employees of the company, who will use the software at work. Certain American defense-related products and information require export approval from the United States Government under the ITAR and EAR. In order to obtain a license to export, the exporter must specify both the end user and the end use for undertaking an end-user certificate. In End-User License Agreements (EULAs ), the end user is distinguished from the value-added reseller, who installs the software or the organization who purchases and manages the software. In the UK, there exist documents that accompany licenses for products named in the end user undertaking statements(EUU). Context. End users are one of the three major factors contributing to the complexity of managing information systems. The end user's position has changed from a position in the 1950s (where end users did not interact with the mainframe; computer experts programmed and ran the mainframe) to one in the 2010s where the end user collaborates with and  advises the management information system and Information Technology department about his or her needs regarding the system or product. This raises new questions, such as: Who manages each resource?, What is the role of the MIS Department? and What is the optimal relationship between the end-user and the MIS Department?. Empowerment. The concept of "end-user" first surfaced in the late 1980s and has since then raised many debates. One challenge was the goal to give both the user more freedom, by adding advanced features and functions (for more advanced users) and add more constraints (to prevent a neophyte  user from accidentally erasing an entire company's database). This phenomenon appeared as a consequence of "consumerization" of computer products and software. In the 1960s and 1970s, computer users were generally programming experts and computer scientists. However, in the 1980s, and especially in the mid-to-late 1990s and the early 2000s, everyday, regular people began using computer devices and software for personal and work use. IT specialists needed to cope with this trend in various ways. In the 2010s, users now want to have more control over the systems they operate, to solve their own problems, and be able  to change, customize and "tweak" the systems to suit their needs. The apparent drawbacks were the risk of corruption of the systems and data the users had control of, due to their lack of knowledge on how to properly operate the computer/software at an advanced level. For companies to appeal to the user, they took primary care to accommodate and think of end-users in their new products, software launches, and updates. A partnership needed to be formed between the programmer-developers and the everyday end users so both parties could maximize the use of the products effectively. A  major example of the public's effects on end-users requirements were the public libraries. They have been effected by new technologies in many ways, ranging from the digitalization of their card catalog, the shift to e-books, e-journals and offering online services. Libraries have had to undergo many changes in order to cope, including training existing librarians in Web 2.0 and database skills, to hiring IT and software experts... End user documentation. The aim of end user documentation (e.g., manuals and guidebooks for products) is to help the user understand certain aspects of the systems and to provide  all the answers in one place. A lot of documentation is available for users to help them understand and properly use a certain product or service. Due to the fact that the information available is usually very vast, inconsistent or ambiguous (e.g., a user manual with hundreds of pages, including guidance on using advanced features), many users suffer from an information overload. Therefore, they become unable to take the right course of action. This needs to be kept in mind when developing products and services and the necessary documentation for them. Well-written documentation is needed for a user to  reference. Some key aspects of such a documentation are: At times users do not refer to the documentation available to them due to various reasons, ranging from finding the manual too large or due to not understanding the jargon and acronyms it contains. In other cases, the users may find that the manual makes too many assumptions about a user having pre-existing knowledge of computers and software, and thus the directions may "skip over" these initial steps (from the users' point of view). Thus, frustrated user may report false problems because of their inability to understand the software or  computer hardware. This in turn causes the company to focus on “perceived” problems instead of focusing on the “actual” problems of the software. Security. In the 2010s, there is a lot of emphasis on user's security and privacy. With the increasing role that computers are playing in people's lives, people are carrying laptops and smartphones with them and using them for scheduling appointments, making online purchases using credit cards and searching for information. These activities can potentially be observed by companies, governments or individuals, which can lead to breaches of privacy, identity theft, by, blackmailing and other serious  concerns. As well, many businesses, ranging from small business startups to huge corporations are using computers and software to design, manufacture, market and sell their products and services, and businesses also use computers and software in their back office processes (e.g., human resources, payroll, etc.). As such, it is important for people and organizations to need know that the information and data they are storing, using, or sending over computer networks or storing on computer systems is secure. However, developers of software and hardware are faced with many challenges in developing a system that can be both user friendly, accessible  24/7 on almost any device and be truly secure. Security leaks happen, even to individuals and organizations that have security measures in place to protect their data and information (e.g., firewalls, encryption, strong passwords). The complexities of creating such a secure system come from the fact that the behaviour of humans is not always rational or predictable. Even in a very-well secured computer system, a malicious individual can telephone a worker and pretend to be a private investigator working for the software company, and ask for the individual's password, a dishonest process called "phishing". As well, even with  a well-secured system, if a worker decides to put the company's electronic files on a USB drive to take them home to work on them over the weekend (against many companies' policies), and then loses this USB drive, the company's data may be compromised. Therefore, developers need to make systems that are intuitive to the user in order to have information security and system security. Another key step to end user security is informing the people and employees about the security threats and what they can do to avoid them or protect themselves and the organization. Underlining  clearly the capabilities and risks makes users more aware and informed whilst they are using the products. Some situations that could put the user at risk are: Even if the security measures in place are strong, the choices the user makes and his/her behaviour have a major impact on how secure their information really is. Therefore, an informed user is one who can protect and achieve the best security out of the system they use. Because of the importance of end-user security and the impact it can have on organisations the UK government set out a guidance for  the public sector, to help civil servants learn how to be more security aware when using government networks and computers. While this is targeted to a certain sector, this type of educational effort can be informative to any type of user. This helps developers meet security norms and end users be aware of the risks involved. Reimers and Andersson have conducted a number of studies on end user security habits and found that the same type of repeated education/training in security "best practices" can have a marked effect on the perception of compliance with good end user network security  habits, especially concerning malware and ransomware. Undertaking. End user undertaking (EUU) is a document saying who the user is, why they are using a product and where they live (or where they work). This document needs to be completed and signed by a person in a position of authority who is in the end user business. All documents should be in English or if not so accompanied by a valid English translation. Usually the EUU is sent together with the product license.
