Case

Case Study 1:
The data entry operators at Melanie Julian Construction have been making errors when entering
the codes for residential siding products, which are as follows:
U = stUcco,
A = Aluminum,
R = bRick,
M = Masonite,
E Z = E Z color-lok enameled masonite,
N = Natural wood siding,
A I = pAInted finish,
S H = SHake SHingles.
Only one code per address is permitted.
Exercise:
1. List the possible problems with the coding system that could be contributing to erroneous
entries. (Hint: are the classes mutually exclusive?)
2. Devise a mnemonic code that will help the operators understand what they are entering and
subsequently help their accuracy.
3. How would you redesign the classes for siding materials? Respond in a paragraph.
4. Some of the materials coded in Problem 4a. above natural wood siding, brick, shake shingles
and E Z color-lok enameled Masonite) are being used in innovative ways for scenic design for
stage plays by some of the consultants for Melanie Julian Construction. Develop a code for the
residential products you coded in 4b. above so consultants will recognize that they can be used
on stage for scenic design as well
