Information to be captured by the system is input through online keying from the six separate departments of:
Sales
Production Planning
Engineering
Cost Accounting
Inventory
Factory Work Stations
The Information to be processed is composed of:Forecasts & Orders
Production Orders & Schedules
Product Specifications
Standard Costs & Overhead Rates
Materials Requisitions
Production Data
This information is processed through a computer system of online production information systems.
Simultaneously, the new information is entered & continually updated into the general ledger & stored online as manufacturing control specifications through a computer process.
At the same time a Computer Integrated Manufacturing Interface (CIM) is prepared from a computer process which produces instructions and schedules for the manufacturing process in which much of the manufacturing is performed and monitored by computerized equipment in part throughout the use of robotics and real time data collection on manufacturing activities.
The instructions & schedules is updated through the CIM interface as new information is input into the system.
The new information updates the production cycle database stored on magnetic disks consisting of:Bill of Materials
Operations List
Master Production Schedule
Inventory
Production Orders
Work in Progress
Database Magnetic Disks
in this particular
Production Cycle Database
are defined as
Bill of MaterialsBill of Materials
A document that specifies

also referred to as “routine sheet”, specifies

“How a product moves through the factory?”
“What is done at each step?”
“How much time each operation should take?”
Master Production Cycle Master Production Cycle
(MPS)(MPS)
“How much of each product is to be produced during the planning period?”
“When that production should occur?”
InventoryInventory
“How much Inventory we have right now?”
“How much we need to order?”
“When to order?”
“What to order?”
Production OrdersProduction Orders
A document authorizing the manufacture of a specified quantity of a particular
product of:
Operations to be performed
Quantity to be produced
Location to be delivered to
Work in ProgressWork in Progress
Indicates product status of:
Complete, ready to be delivered to its final destination or
Incomplete, in need of materials or equipment
Ultimately, the Production Cycle Database is accessed by:
Sales
Production Planning
Cost Accounting
Factory Supervisors
The Production Cycle Database is made accessible by an:
Inquiry Processing SystemInquiry Processing System
Processing user information queries by searching master files for the desired
information into an appropriate response
The Inquiry Processing System The Inquiry Processing System inquires information so new inquires information so new

This cycle continues till all the new This cycle continues till all the new information is input and updated information is input and updated
into the database, so it can update into the database, so it can update reports which provide specific reports which provide specific
departments with the information departments with the information they need.they need.

Terminals & Data Entry Employees Terminals & Data Entry Employees ControlControl
Prevent data from being misplaced or mishandled by outsiders who may be able to enter the database
• Incorporate passwords
• Personal Identification Numbers (PIN)
Data Entry C0ntrolsData Entry C0ntrols
• Field Check – Checks for the appropriate character type in a field
• Sign Check – Checks for the appropriate arithmetic sign
• Limit Check – Ensures a numerical value doesn’t exceed a predetermined value
• Range Check – Checks numerical values with lower & upper limits
• Size Check – Determine if data will fit in the assigned field
• Completeness Check – Make sure all required items are entered
• Validity Check – Compares ID Code/Account # with a similar data in the master file
• Reasonableness Test – Determines the correctness of the logical relationship between 2 data items
• Data Entry Bath Totals
Authorization ControlAuthorization Control
Keep the database as accurate and error free as possible
• Implemented by creating an “access control matrix”
• “Access Control Matrix” is a table specifying which portions of the system users are permitted to access & what actions they can perform
Data Back-up ProceduresData Back-up Procedures
Keep the data from being lost or erased
Provides “fault tolerance” through a process called “restoration”. There are two types of back-ups:
1. Incremental Backup: Saves changes since the last back-up.
2. Differential Back-up: Saves all changes since the last back-up.
Additional Controls:Additional Controls:
• Physical Inventory Counts – to keep Inventory accurate
• Firewall Protection – to protect outsiders from stealing or ruining the authentication of the data
• Write-Protection – protects against accidental writing over or erasing of data files stored on magnetic disks
