Q

Inputs :

A

Inputs to the process are mainly materials (natural or processed resources, parts and components), information, and customers.

There maybe other inputs like money and energy too.

Usually one of the above is dominant, e.g. material in manufacturing processes, information in accounting processes, and customers in healthcare processes.

Q

Process:

A

Processes may:

  • Transform the physical properties of the materials (e.g. in manufacturing process) or customers (e.g. in hairdressing process)
  • Change the location of materials (e.g. in parcel delivery process) or customers (e.g. in air transport process)
  • Store materials (e.g. in warehousing process) or customers (e.g. in hotel process)
  • Synthesize or analyse information (e.g. in accounting process)
  • Transform physiological (e.g. in health care process) or psychological (e.g. in entertainment process) state of customers.

Q

Outputs:

A
  • The outputs of some processes are just products, others just services, but most a mixture of the two

Q

The five elements of the Process View are:

A
  • Input / Output
  • Flow Unit
  • Network of activity and buffers
  • Ressources
  • Information structure

A flow unit may be a unit of input, such as a customer order, or a unit of output such as a finished product, or the value of input or output.

Q

Example of the five elements of the process view:

A

The process of treating minor patients in an emergency department

  • Input / Output: minor patients / healthy patients
  • Flow unit: a patient
  • Network of activities and buffers: as given in the diagram
  • Resources:
    • Human: nurses, doctors, ECG technician, radiologist, etc.
    • Capital: beds, cubicles, ECG machine, etc.
  • Information structure: a system tracking amount of time each patient has been in the A&E

Q

Product Quality=

A

The degree of excellence that determines how well the product works. It depends on:

  • Features (what it can do?)
  • Performance (how well it functions?)
  • Reliability (how consistently it works over time?)
  • Serviceability (how quickly it can be restored?)
  • Aesthetics

Q

Customer Value Proposition=

A

A set of benefits (in four dimensional space) that the firm offers to customers.

  • McDonald’s value proposition:
    • Inexpensive food delivered quickly from a standard and limited menu with average quality
  • Zara’s value proposition:
    • Timely fashion for the masses. Timely yet limited variety at modest cost and quality
18
Q

19
Q

Product Attributes & Process Competencies:

A

Process competencies determine the product attributes that the process is particularly good at supplying

20
Q

Process Competencies=

A
  • Process Cost
  • Process Flexibility
  • Process Quality
  • Process Flow Time
21
Q

Process Cost =

A

The total cost of producing and delivering products and services.

22
Q

Process Flexibility =

A
  • Scope flexibility: the ability of the process to produce and deliver a range of products and services. It requires flexible resources, e.g. cross-trained workers, general-purpose machines
  • Volume flexibility: the ability of the process to deal with fluctuating demand.
23
Q

Process Quality =

A

The ability of the process to deliver quality products.

24
Q

Process Flow Time =

A

The total time needed to transform a flow unit from input to output

or

The average flow time of individual flow units

25
Q

Process Architecture =

A

Type of the resources used to perform the activities and their physical layout in the processing network.

  • Process competences are strongly influenced by the process architecture.
  • Two extreme process architectures:
    • Job shop architecture
    • Flow shop architecture
26
Q

Job Shop Architecture =

A

Uses flexible resources to produce low volumes of highly customized variety products.

  • Examples are tool and die shops, management consultancy firms, and general hospitals.
  • Similar resources are located together in a layout that is called a functional layout, e.g. press machines in stamping department, or x-ray machines and radiologists in imaging department.

27
Q

Flow Shop Architecture =

A

Uses specialized resources that perform limited tasks with high precision and speed.

Resources are arranged according to the sequence of activities needed to produce a particular product, with limited storage space between activities, in a layout called product layout.

Only for manufacturing?

28
Q

Process Competencies =

A
  • Process competencies for job shop architecture:

High flexibility, long flow time (both in material handling and processes), high variable cost but often low initial investment, high quality but may not be consistent

  • Some other challenges of job shop architecture

Complicated workflows, slow material handling over long distances, large volume of inventories, difficult product tracing, difficult product scheduling

29
Q

What are the process competencies associated with flow shop architecture?

A

Low flexibility, short flow time, low variable cost but often high initial investment (since volume is high, the unit price is often low), consistent quality

30
Q

Operations Strategy =

A

The concept of strategy originated in military terminology, where strategy refers to plans devised to outmanoeuvre the opposition. In business, firms attack where and when other firms are vulnerable.

Today it simply means a specific plan of action to reach a particular objective.

31
Q

The strategy Hierarchy:

A

Corporate Strategy: Identifies the industries in which the corporate will participate, configures business units for each industry, and acquires and allocates corporate resources to each business

Business Strategy: Seeks a favourable competitive position in an industry. It can be described in terms of a customer value proposition, i.e. the position that the firm wants to occupy in the competitive product space (the so-called strategic positioning)

Marketing Strategy: How the market will be segmented, how the product will be positioned, priced and promoted

Financial Strategy: How capital will be raised and invested

32
Q

Trade-Off’s and Efficient Frontier =

A
  • Operations have to make trade-off’s (a giving up of one thing in return for another)
  • Efficient frontier is the smallest curve that contains all current industry positions.
33
Q

Operations Management =

A
  • Structure the process competencies in the direction of the customer value proposition.
  • Develop measures to evaluate the effectiveness and efficiency of the processes.
    • In general management definition, effectiveness means ‘doing right things’, while efficiency means ‘doing things right’.
    • In Operations Management, cost efficiency is achieving an output with minimum input, while an effective process is a process that supporting execution of company’s strategy.
  • Apply methods and techniques to improve process performance
