How CASE tools improve programming productivity:
1. They automate code generation, testing and control rollout thus enabling programmers to
accomplish their tasks within a short period of time.
2. They automate tedious and error-prone portions of analysis and design thus freeing
programmers to more creative problem-solving tasks.
3. They organize and correlate design components and provide rapid access to them via a
design repository thus facilitating group collaboration.
4. They improve communication between users and technical specialists thus resulting in
quality systems being developed.

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.
