Process Design
Design:
  “To design” refers to the process of originating
  and developing a plan for a product, service or
  process.

Process:
  Is any part of an organization which takes a set
  of input resources which are then used to
  transform something into outputs of products
  or services.

Prototyping and final
       design
Nature of the design activity:
1) Design is inevitable – products, services and the
   processes which produce them all have to be
   designed.
2) Product design influences process design –
   decisions taken during the design of a product or
   service will have an impact on the decisions taken
   during the design of the process which produces
   those products or services and vice versa.
Product & services design are
           interrelated to its process design

                 Product or             Processes that

                                          or Service

                                       Processes should be
         Products and services         designed so they can

          such a way that they          and services which
            can be created             the operation is likely
              effectively                   to introduce




Decisions taken during the design of the product or service will have
    an impact on the process that produces them and vice versa
Process Design and Product/Service Design are Interrelated
•   To commit to the detailed design of a product or service
    consideration must be given to how it is to be produced.
•   Design of process can constrain the design of products and
    services.
•   The overlap is greater in the service industry:
     • Service industry - it is impossible to separate service
          design and process design – they are the same thing.
     • Manufacturing industry - it is possible to separate
          product design and process design but it is beneficial to
          consider them together because the design of products
          has a major effect on the cost of making them.
Process and product/service design must satisfy customer
• Products/services designer customers satisfaction criteria
    • Aesthetically pleasing
    • Reliability
    • Meets expectation
    • Inexpensive
    • Quality
    • Easy to manufacture and deliver
    • Speedy
• Process designer customers satisfaction achieved through:
    • Layout
    • Location
    • Process technology
    • Human skills

Designing processes
•   Process mapping
•   Process mapping symbols
•   Improving processes
•   Process performance
•   Throughput, cycle time & work in process
Process mapping
•   Used to identify different types of activities.
•   Shows the flow of material, people or
    information.
•   Critical analysis of process maps can improve
    the process.
Process performance
•   Process performance can be judge against the
    five key performance objective:
        Quality
        Speed
        Dependability
        Flexibility
        Cost
Throughput, work content, cycle time, and
work in process
 •   Throughput – the time for a unit to move through the
     process
 •   Work content – the total amount of work required to
     produce a unit of output (measured in time)
 •   Cycle time – The average time between units of
     output emerging form the process
 •   Work in process (WIP) –unfinished items in a
     production process waiting for further processing e. g.
     when customers join a queue in a process they
     become WIP
     throughput = work in process x cycle time
Process Types
Project Processes
• One-off, complex, large scale, high work
  content “products”
• Specially made, every one customized
• Defined start and finish: time, quality and cost
  objectives
• Many different skills have to be coordinated
• Fixed position layout
Project Process
Jobbing Processes
• Very small quantities: “one-offs”, or only a few
  required
• Specially made. High variety, low repetition.
• Skill requirements are usually very broad
• Skilled jobber, or team of jobbers complete
  whole product
• Fixed position or process layout (routing
  decided by jobbers)
Jobbing Process
Batch Processes
• Higher volumes and lower variety than for
  jobbing
• Standard products, repeating demand. But
  can make specials
• Specialized, narrower skills
• Set-ups (changeovers) at each stage of
  production
• Process or cellular layout
Batch Process
Mass (Line) Processes
•   Higher volumes than Batch
•   Standard, repeat products
•   Low and/or narrow skills
•   No set-ups, or almost instantaneous ones
•   Cell or product layout
Mass Process
Continuous Process
• Extremely high volumes and low variety: often
  single product
• Standard, repeat products
• Highly capital-intensive and automated
• Few changeovers required
• Difficult and expensive to start and stop the
  process
• Product layout: usually flow along conveyors
  or pipes
