3. WHERE DOES PROCESS DESIGN REALLY BEGIN?

THE BEGINNING OF PROCESS DESIGN

Process Design in a manufacturing environment usually starts during the Product Design. The designer, or design engineer, must consider a broad range of operational issues throughout product design. 

Process design begins by dividing the product into a number of components, sub-assemblies, and final assembly. At this stage the product's Explosion Chart, Parts List, and Bill Of Materials needs to be prepared.

The Explosion Chart and the Parts List summarize all details pertaining to components and sub-assemblies required to complete one product unit.

The Bill of Materials contains detailed specifications, weight, or dimensions of raw materials required to complete the final product assembly.

4. SMALL BUSINESS EXAMPLE
PRELIMINARY PRODUCT DESIGN

PRELIMINARY PRODUCT DESIGN

To illustrate the procedures involved in the Product And Process Design, consider the manufacture of a low-fat Eskimo Pie. Although it may seem to be a simple product, its’ manufacture, as you will see, will require some serious planning.

Assume that a reputable ice-cream manufacturer conducted a thorough market research and concluded that there is a substantial market of Eskimo Pie lovers. Subsequently, the manufacturer has decided to invest $500,000 for building a new product line in its existing manufacturing facility. This product line will be completely self-sustaining and independent from all other manufacturing activities.

Process design of the Eskimo Pie must begin with the product design and include the following:

  • • Product Explosion Chart.
  • • Parts List.
  • • Bill Of Materials.

These important documents are illustrated below.

5. SMALL BUSINESS EXAMPLE

ROUTE SHEET

14. PRODUCT ASSEMBLY CHART

PRODUCT ASSEMBLY CHART

The Product Assembly Chart helps to clarify the sequence of operations required throughout the product assembly process. 

Each operation must be examined separately and its estimated time recorded in the Flow Process Chart. This chart helps in summarizing a detailed flow of operations pertaining to a specific repetitive task. 

It is useful, therefore, to prepare a Product Assembly Chart for any product which is intended to be manufactured in large quantities.

In many other instances the finished product may consist of a large number of components, and often require manual assembly. In this case, the Product Assembly Chart may be very helpful by providing the guidelines for complete assembly of the finished product.

In the case of the Eskimo Pie example, the Product Assembly Chart is not required since the finished product consists of two items only and its' assembly is fully automated.

15. PROCESS DESIGN AND CAD-CAM

IMPORTANCE OF PROCESS DESIGN

The Process Design procedure is frequently used when products are manufactured in large quantities. Such a procedure usually requires substantial investment in time and should, therefore, remain cost-effective when smaller quantities are produced. 

Process Design For Services And Projects also entails sub-division of the complete operation into separate components and evaluation of each component on an individual basis.

Product And Process Design Procedures have been upgraded through the extensive use of modern computer technology. A broad range of computer-aided design equipment and software are available and is widely utilized by designers and engineers. There are several variations of software packages used for product and process design applications as presented below.

 

THREE TYPES OF SOFTWARE

   
Computer-Aided
Design (CAD)
  Computer-Aided
Manufacturing (CAM)
  Computer-Aided Design And
Manufacturing (CAD-CAM)
 

Each type of software is briefly discussed below.

COMPUTER-AIDED DESIGN (CAD)

Computer-Aided Design (CAD) is a process of using computers for the purpose of designing new products and modifying the existing ones.

17. PROCESS MAPPING AND VALUE STREAM MAPPING

PROCESS MAPPING

Process Mapping provides a visual display of any type of an operational process flow within an organization. This process is particularly important in the operations department where products or services are produced for customers.

 
Process mapping offers the following important advantages:
 
Provides a detailed identification and sequence of steps in the operational process.
Helps in a detailed evaluation of the operational process flow.
Helps in identifying value-added activities
Helps in identifying wasteful non-value-added activities, such as unnecessary delays.
Helps to improve operational process efficiency.
Helps to improve the flow of documentation during the operational process.
Helps to improve communication among employees related to the operational flow.

Upon starting the process mapping of a particular operational process it is necessary to:

1. Describe the process that is subject to process mapping.

2. Identify the purpose of this process.

Specific questions during a mapping process are outlined below.

QUESTIONS RELATED TO PROCESS MAPPING
