Current State Analysis

System Overview

The client for the project is interested in receiving an upgrade for their warehouse management

system. The mission of the project is to modernize, increase efficiency and reduce errors that

take place in their supply chain system. Currently the clients are using a fax based system to send

and receive orders. This system is crucial to the company because they need it to receive parts

that are required in their product. The company is looking to modernize this system and move

their records into a database. Their reason for wanting to do this is because currently they are

experiencing manual errors caused by employees. They would like for us to increase processing

speed, reduce errors and create more standardization.

The warehouse management system within the company is broken down into three different

divisions. The first division is order placement (OP) which is where they will create orders,

receive missing orders, reorder missing orders and send orders to be recorded. This division is

used mostly at their assembly plant that is used to build vehicles. The clients would like this

system to be able to order multiple products in multiple quantities as a single order. They

currently have been having issues with order fulfillment and would like the ability to list

previous orders that were either damaged or missing with the capacity to reorder them along with

other items that have not been recently purchased. They would also like to be able to review

order totals and have the power to edit their line items.

The second division in their warehouse management system is order fulfillment (OF). In this

division they receive order information from order placement and store it on their data base.

After that the products are placed onto pallets and then are identified by their RFID tags. Finally

as the pallets are shipped out an Advanced Shipping Notice (ASN) is then sent to the third

division. In this area of the warehouse management system they would like the ability to view

received orders and to be able to pack multiple orders on a single pallet. They would like to be

able to do this because they follow the business accounting rule of first in first out (FIFO) for

their inventory. The clients also need to be able to have more control over what pallets are being

shipped and the details of the order. They stress that the order fulfillment division must follow

what they call the Pack Three rule. This means that for every shipment they must pack at least

three line items into a pallet and at least three pallets to a shipment.

The final division of our client’s warehouse management system is order receiving (OR). This

division is used for receiving orders of parts for their automobiles. They will simulate the

delivery of the products by using a RFID scanner. This information is then entered into the data

base and will update the order placement division on the status of the order that was placed. In

this area of the warehouse system the clients would like to have the capability of using the RFID

to update current statuses at the shipping dock. They would also like the RFID to be able to show

if an order is missing or damaged.

The issues that our client has been experiencing are causing them to slow down their business

and become less efficient. When we are done with the project we will have resolved most of their

issues by modernizing their technology. This technology will help aid them in being more

organized and efficient through the use of the databases we created. It will also help resolve the

manual errors that are occurring within the company because of the massive paper trail their

current fax based system is causing. Our goal for this project is to resolve all the issues

surrounding the current system while at the same time improving the functionality of our clients

company.

Known Issues List

Outdated technology

o Current fax based management system is cumbersome and is inefficient

Often responsible for causing manual errors and slow processing speeds

Lacks the ability of error control and ability to detect delays on parts

All data and information is saved on paper, there is so much paper it has become

more difficult to store it, organize or track files

Lack of a centralized information system that automatically inputs and updates order information

in database

Inability to list ordered items that never got fulfilled and reorder them with other new items

Inability to review the total of an order or change quantities or remove items from an order

Lack of the ability to review data about previous shipments that have been moved on to OR

There is no way to review shipments and their contents or confirm status of the LineItems
