Risks associated with end user computing:
1)Risks in problem analysis.
Users may proceed to solving problems without adequate problem specifications.
2) Development risks.
Persons who do not have systems development training and experience are more
susceptible to modelling errors. They may fail to apply documentation standards and test
their system adequately.
3) Redundancy End users may spend time and effort developing applications that have already been
developed by commercial software firms.
4) Unprofitable expenditure of time and effort.
It‘s questionable whether people with professional skills other than systems development
should spend time developing applications rather than concentrate on their areas of
expertise.
5) Waste of computing resources
Without proper budgetary restraints, the use of end user computing resources may be
uneconomical.
6) Threats on privacy and security
Physical access, custodianship controls, backup and recovery issues are seldom addressed
by end users.
7) Lack of computing efficiency and effectiveness
Few end users establish procedures for evaluation of their systems or subject them to
audits.
8) Incompatibility of end users tools and devices with the rest of the
organization‘ssystems. Standards are required to overcome this.

(Solved)
Farmquip Ltd. designs and manufactures irrigation equipment. The irrigation equipments
are sold to flower nationality. The company regards customer service, that is the ability to
respond effectively and properly to service calls as critical to its success.
Initially, field engineers inspect faulty irrigation equipment. Currently three quarters of the
faulty irrigation equipment are referred to the repair centre, to be mended by the repair
centre.
Engineers, resulting in a turnaround time of up to 10 days. The company has decided to
investigate the possibility of carrying out more field repairs with the aid of a portable expert
system, in order to reduce the turnaround time.
The prototyping approach was used, and an evaluation of the final prototype made it clear
that an expert system used in conjunction with 11.1ptop microcomputer would improve the
situation to the extent that only 10% of irrigation equipment would need to be returned to
the repair centre, with majority of repairs being carried out at the customers‘ premises by the
field engineers.
Required
(a) Define the term expert system and explain how it could be of use in this context.
