Areas of interest addressed by a structured walkthrough:
1) Program requirements
The structured walkthrough uncovers any inconsistencies between requirements stated by
the users and those that the analyst is proposing.
2) Program designs
Structured walkthroughs determine whether the proposed design will meet requirements of
the system and user. If the review team finds any discrepancies between the design and the
requirements, they should provide solutions to the discrepancies.
3) Programs
The structured walkthrough is conducted to examine the program development along with
its documentation. The programs are compared with their specific design specifications to
determine whether the specifications are being satisfied. Any programming errors are dealt
with.
4) Testing
The structured walkthrough assists in development of test data that can be used to detect
system design errors.

(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.
