1 Processes and Technologies

2 Process (Definition of) Process: Any part of an organization that takes inputs and transforms them into outputs

3 Process Flowcharting (definition of) Process flowcharting is the use of a diagram to present the major elements of a process The basic elements can include tasks or operations, flows of materials or customers, decision points and storage areas or queues It is an ideal methodology by which to begin analyzing a process

4 Flowchart Symbols (1 of 2) Tasks or operations Examples: Giving an admission ticket to a customer, installing an engine in a car, etc. Decision Points Examples: How much change should be offered to a customer, which tool should be used, etc.

5 Examples: Sheds, lines of people waiting for a service, etc. Examples: Customers moving to a seat, mechanic getting a tool, etc. Storage areas or queues Flows of materials or customers Flowchart Symbols (2 of 2)

6 Example 1: Flowchart of Student Going to School Yes No Goof off Go to school today? Walk to class Drive to school

7 Example 2: Flowchart for Inspection Process Material Received from Supplier Inspect Material for Defects Defects found? Return to Supplier for Credit Yes No, Continue…

8 Processes Conversion (ex. Iron to steel) Fabrication (ex. Cloth to clothes) Assembly (ex. Parts to components) Testing (ex. For quality of products)

10  Process Selection: Deciding on the way production of goods or services will be organized  Process selection can involve substantial investment in  Equipment  Layout of facilities

11 To Accompany Russell and Taylor, Operations Management, 4th Edition,  2003 Prentice-Hall, Inc. All rights reserved. Process Selection Has Major Implications for: Capacity planning Layout of facilities Equipment Design of work systems

13 Process Strategy Process strategy defines the overall approach to producing goods and services Key Aspects of Process Strategy: – – Capital Intensity The mix of equipment and labor that will be used by the organization – – Process flexibility The degree to which the system can be adjusted to changes in processing requirements due to such factors as – – Product and service design changes – – Volume changes – – Changes in technology – – Vertical integration – – Customer involvement

14   Required Variety,   Required Volume (how many)   Required Flexibility (degree of) Factors that Affect Process Decisions

15 From Function to Process Manufacturing Accounting Sales Purchasing Product Development Order Fulfillment Supply Chain Management Customer Service FunctionProcess

16 Process Selection Variety – How much Flexibility – What degree Volume – Expected output Job Shop Batch Repetitive Continuous

17 Types of Processes (Process Flow Structures) Projects Job shop Batch production Mass production/assembly (repetitive) Continuous flow production

18   Projects (nonroutine jobs)   Job shop Small scale (e.g. copy center making a single copy of a student term paper)   Batch Moderate volume (e.g. copy center making 10,000 copies of an ad piece for a business) Types of Processes (1 of 2) Determine how to produce a product or provide a service

19   Mass production/assembly High volumes of standardized goods or services (e.g. Automobile manufacturer)   Continuous Flow Line Very high volumes of non-discrete goods (eg. Petroleum manufacturer) Types of Processes (2 of 2)

22 Process Focused (intermittent process) Repetitive Focus (assembly line) Product Focused (continuous process) Continuum High variety, low volume Low utilization (5% - 25%) General-purpose equipment Low variety, high volume High utilization (70% - 90%) Specialized equipment Modular Flexible equipment Types of Process Strategies Process strategies follow a continuum Within a given facility, several strategies may be used

23 Process-Focused Strategy   Facilities are organized by process   Similar processes are together   Example: All drill presses are together   Low volume, high variety products   ‘Jumbled’ flow Operation Product A Product B 112233   Other names   Intermittent process   Job shop   Batch

Product and Service Profiling Process selection involves – – Substantial investment in equipment – – Has a very specific influence on layout Product or service profiling – – Linking key product or service requirements to process capabilities – – Key dimensions relate to Range of products or services that will be processed Expected order sizes Pricing strategies Expected frequency of schedule changes Order-winning requirements

33 Transition From Product Design to Process Design: Product and Production Documents

34 Engineering drawings – – Shows dimensions, tolerances, & materials – – Shows codes for Group Technology Assembly drawing -- Shows exploded view of product Bill of Material – – Lists components, quantities & where used – – Shows product structure Product Documents

35 Engineering Drawings - Show Dimensions, Tolerances, etc.
