End user computing (EUC) refers to systems that allow non-programmers to create applications. EUC aims to better integrate end users into computing by allowing them to perform complex problem solving. End users are non-IT professionals, including managers and support staff. While EUC gives users control and tailors systems to their needs, it can also cause issues like inappropriate applications and integration problems if not managed properly.

In computing, End User Computing (EUC) refer to systems in
which non-programmers can create working applications.
EUC is a group of approaches to computing that aim at better
integrating end users into the computing environment. These
approaches attempt to realize the potential for high-end
computing to perform in a trustworthy manner in problem
solving of the highest order

3. END USER COMPUTING
 The term end-user computing has different meanings according
to the context in which it is used. The following statements could
all refer to end-user computing:
◦ all tools by which non-data-processing staff handle their own
problems without professional programmers;
◦ creative use of data processing by non-data-processing experts;
◦ complex computing by non-data-processing professionals to
answer organisational information needs;
◦ non-technical end-users using user-friendly, fourth-generation
languages (4GLs) and PCs to generate reports or build decision
support systems;
◦ the use of computer hardware and software by people in
organisations whose jobs are usually classified as net users of
information systems rather than net developers of information
systems.

11. END USER COMPUTING
 The three main types of end-user computing can be defined as:
◦ End-user-developed computer-based information systems for
personal, departmental or organisation-wide use, where the end-
user is a non-IT professional;
◦ End-user control of which hardware and package applications are
purchased for use in their department;
◦ End-user use of existing information systems.

12. END USER - development
 End-user development of applications represents a major trend
in the use of information technology in organisations.
 McGill et al. (2003) explain that:
‘User-developed applications (UDAs) are computer based
applications for which non-information systems professionals
assume primary development responsibility.
They support decision making and organizational processes in the
majority of Organizations’

13. END USER - Applications
 Reports from a corporate database using standard enquiries defined by the IS/IT
function
 Simple ad hoc queries to databases defined by the user. For someone in an
airline, for example, these might include access to a frequent flier
database, customer reservation system or crew rostering system to monitor
performance of each
 What-if? analysis using tools such as spreadsheet models or more specialised tools
such as risk or financial management packages or business intelligence
software, used for monitoring sales and marketing performance of information
stored in a data warehouse
 Writing company information for a company intranet
 Development of applications such as a job costing tool or production scheduling
system, using easy-to-use, high-level tools such as application generators, PC
database management systems such as Microsoft Access or Borland or visual
programming environments such as Microsoft Visual Basic.

14. END USER COMPUTING
 Applications backlog: The demand for new applications by users exceeds the
capacity of the IS department or IS outsourcing company to develop them.
 Improved toolsets such as Visual Basic for Applications
 The desire by users to query and analyse data and generate reports from
information stored on databases available across the corporate network
 A trend to decentralisation of computing to user departments for systems to
support departmental activities
 Reduced expense of application development when conducted by end-users
(from departmental rather than information systems budget)
 Better fit between end-user-developed software and their requirements (since no
requirements translation is needed between the users and third-party
developers). End-users are also less likely to ‘over-engineer’ a solution to a basic
problem than an IS professional who will want to treat every problem with rigour.

 Isolation: A few scattered pioneers of EUD develop small-scale business tools within their area.
Initially, little support from central IS.
 Standalone: Larger-scale applications that may be of importance to a department are developed. At
this stage, an information centre may be developed to support an increase in demand for user
computing services.
 Manual integration: Here, different end-user applications need to exchange data. This happens
through manual intervention, with files being transferred by floppy disk or across the network or even
with rekeying of information. Information centre development has continued to support the needs of
these larger-scale applications by providing training and skills and specifying standards for
hardware, software and the development process.
 Automated integration: Users start to link into corporate applications to gain seamless access to
information.
 Distributed integration: At this stage of development, there is a good level of integration between
different end-user applications and corporate systems. Good standards of metadata (or data describing
data in a data dictionary) are required to help achieve this.

17. END USER COMPUTING
 Using information that is out of date
 Information requires export from other information systems before
it can be analysed by the end-user application
 Corruption of centrally held data by uploading erroneous data
 Development of insecure systems without password control that
are vulnerable to accidental and deliberate damage.

18. END USER COMPUTING
 Training: Provision of relevant training courses both in how to program and in how to approach systems
development in a structured way (the second of these is often omitted). This happened at the Open
University, where many of the end-users wanted to omit the analysis course.
 Suitability review: Authorisation of major end-user new developments by business and IS managers to check
that they are necessary (this should not be necessary for smaller-scale developments since otherwise creativity
may be stifled).
 Standards for development: Such standards will recommend that documentation and structured testing of all
user-developed software occurs. Detailed standards might include clear data definitions, validation rules, backup
and recovery routines and security measures.
 Guidance from end-user support personnel: IC or help-desk staff can provide training in techniques used to
develop software.
 Software and data audits: Regular audits of software produced by end-users should occur for data and
application quality. There is an apocryphal story of a company that had an end-user-developed spreadsheet for
making investment decisions which had an error in a formula that lost the company millions of pounds each year!
 Ensuring corporate data security: Ensure that users are not permitted to enter data directly into central
databases except via applications especially written for the purpose by the IS department which has the
necessary validation rules to ensure data quality. For analysis of corporate data, data should regularly be
downloaded from the central database to the PC for analysis, where they can be analysed without causing
performance problems to the corporate system.

19.  Help desk: A central facility in an
organisation which provides end-user help-
desk services such as phone support for
troubleshooting end-user software and
hardware problems, training, guidance on
end-user development and management of
user information.
