Student Book Exchange

A student organization that you belong to, Club For Over Achievers (CFOA), has an opportunity to start a student book exchange at this university. Although there has been a student book exchange sporadically in the past, this is the first time that the book exchange will be officially sanctioned by the university. In the past, various students ran it, but it was not affiliated with any particular student organization. Therefore, the book exchange did not have any continuity from year to year. Your job is to help design the information system to help run this book exchange. Up to this point, there have been a few informal discussions between other members of CFOA, university administration, and the bookstore. From those discussions, your club president has put together the following list of requirements. This document is only a preliminary attempt at documenting requirements.

General Requirements

• All books will be sold on a consignment basis. This means that CFOA will not actually buy used books from students to resell; it will simply act as an agent to bring buyers and sellers together. CFOA will charge a consignment fee based on a percentage of the sales price.
• CFOA will take possession of books to be sold. It is expected that most students will choose to place their books on consignment at the end of the semester, and CFOA will hold the books until the following semester, when most students buy their books.
• No one is sure how many students will choose to use the bookstore, but the book exchange should be able to handle several thousand books each semester.
• Sellers of books will be able to determine the sales price for books they want to sell.
• Sellers will receive a copy of a contract that lists the book, the sales price, consignment fee, and terms for returning the book or their receipt of a check.
• After a specified time (e.g., three weeks after classes start), all sellers of unsold books must be notified that their book was not sold. They then have a period of time in which to pick up their books.
• CFOA will obtain from the university a copy of all book titles that will be required for courses the following semester. This list will include the book title, authors, edition, course title and number, and professor name.

A general description of the current turn-in and sales process for obtaining books for consignment follows:

• The seller will take his/her books to the book exchange location. There s/he will fill out a blank contract one for each book. Note that the contract includes the sales price for the book.
• From that point on, each book must be tracked so that CFOA can tell which sellers' books have been sold. It is not clear at this time how this tracking should be done. The sales price for each book needs to be marked on the book.
• Books will be stored until the beginning of the following semester, at which time the book exchange will be open to buyers.
• Buyers will enter the book exchange area and be able to browse the book stacks (organized by course) to choose which books they would like to buy. They could then take their chosen books to a checkout area. Upon checkout, the book price should be verified against the price the seller agreed to on the contract.
• The total sales amount must be totaled, and sales tax calculated. A receipt must be provided to the buyer.
• Once a book is sold, record of the sale and when the sale occurred must be made so that the seller can receive her/his money.
• If the book is not sold three weeks after the start of the semester, the seller must be notified so that s/he can come and pick up her/his book.

General Operational considerations

• The system will be used by many volunteer workers who probably won't receive much training. Therefore, it should be easy to learn and use.

The Book Exchange

Consignment Process

General Overview:

The consignment process consists of two main stations. Station A is manned with two to three personnel (Clerk A). Station B is manned by one to two personnel (Clerk B).

A supervisor oversees the operations of the Exchange. The supervisor is also be available at the front of the process to inform students of the Exchanges purpose and general procedures. This allows clerks A and B to concentrate on their specific duties in an effort to consign books as quickly and efficiently as possible.

Clerk A completes the following steps:

1. Verify book(s) against valid book list.
2. Instruct seller to fill out book information for valid books (book number, course). ONLY ONE BOOK PER CONTRACT.
3. Help student determine selling price.
4. Instruct student to fill out mailing address and sign contract and proceed to Clerk B

Clerk B completes the following steps:

1. Sign contract.
2. Print out contract, and separate into its three parts.
3. Place top copy (white) of the completed contract in book
4. Give bottom copy (pink) of the completed contract to student.
5. Give additional information sheet to student. Emphasize to the student that the copy of the contract must be kept in order to pick up payment or any unsold book.
6. Place price and contract number stickers on the bottom of the books binding (contract number should be above selling price).
7. Place middle copy (yellow) of the completed contract in filing cabinet

More Specific:

Clerk A:

A student will bring one or multiple book(s) to be consigned. Clerk A will look up each of the students books (by author) to determine if it is listed in the valid book list.

Clerk A will assist the student in filling out the book information (one contract per book) for the number of valid books that the student has and will also help the student determine a reasonable selling price.

Clerk A will also make sure that the student understands exactly what dollar amount he/she will receive for his/her book if it is sold. This amount will be calculated as 90% of the selling price (the 10% is the Exchanges commission) and will be noted in the Your Profit blank.

Clerk A will then instruct the student to proceed to another table to fill out his/her mailing address information as well as read the terms of the contract.

Important Time Saver: If the student has multiple contracts, the student only need fill out his/her name, address, city, state, and zip on one contract. On the others, he/she need only write in his/her last and first name. The system should populate the remaining information.

Clerk B:

The second clerk will then make sure that the student has signed each contract and correctly filled in the mailing address section. Clerk B will then sign, print, and separate the contract into three parts.

1. The bottom copy (pink) will be given to the student.
2. The top (white) copy will be taped to the inside cover of the book,
3. The middle copy (yellow) will be filed.

As indicated above, if the student has multiple books, the student need only fill out the top information box in its entirety once. On the rest of the contracts, the student need only fill out his/her last and first name. Clerk B will staple all the yellow copies together (with the one that has the complete information on the top) and place these in the file.

Before the student leaves with the completed contract for each consigned book, Clerk B will give the student an information sheet that indicates the selling times and where & when checks and unsold books can be picked up.

After the student leaves, Clerk B will write the contract number and selling price on small stickers (contract number on one, and selling price on another) and place these stickers on the bottom of the books binding. For consistency, contract number should be placed above selling price.

Sales Process

General Overview:

There are two main functions in the sales process. Clerk A retrieves books and clerk B records the sale and collect payment.

A student will hand his/her class list to clerk A. The clerk will then look at an inventory listing of books to determine if it is in inventory. The primary purpose of the inventory list is to give the clerk an ability to check at the counter without going to check the physical inventory for books that the Exchange absolutely does not have. Clerk A will then retrieve the books that the student needs from the physical inventory stacks. Books will be sold on a Low Cost First Out (LCFO) basis. Books with the same price will be sold based on lowest contract number, that is, the book that was consigned first. The clerk will quickly scan the price stickers on the books binding and grab the appropriate book. The clerk will show the student and say this is the book with the lowest price, will this be ok? After retrieving all the books for the student and pending student approval of each book on his/her class list, the clerk will then instruct the student to proceed to the cash register.

Clerk B, who will operate the cash register, will remove the white copy of the contract from the inside of the book(s), stamp the books with a special Book Exchange stamp with blanks for selling price and sold date, and enter in the selling price and sold date. The clerk will total the sale, adding a 5% state of Idaho tax on the total sales amount, and collect the money from the student. The register will print a sales receipt for the student and a copy for the Exchange. The white copy of the contracts will be placed in a file for later batch data entry.
