What is a Business Process?

1. A pragmatic definition
   A Business Process describes how something is done in
   an organization


   In general terms…

   Business - Organizational entity that deploys resources to provide
              customers with desired products and services

   Process (Merriam-Webster’s Dictionary)
             (i)   A natural phenomenon marked by gradual changes
             that
                   lead to a particular result
             (ii) A natural continuing activity or function.
             (iii) A series of actions and operations conducing to an   2
             end.
What is a Business Process?


A process specifies the transformation of inputs to outputs



            Inputs      Process      Outputs


           The transformation model of a process


Different types of transformations
  •   Physical (Ex. raw material ⇒ finished product)
  •   Locational (Ex. flying from Denver to L.A.)
  •   Transactional (Ex. depositing money in a bank)
  •   Informational (Ex. accounting data ⇒ financial statement)
                                                                  3
What is a Business Process?
3. A more comprehensive process definition
   A business process is a network of connected activities and buffers
   with well defined boundaries and precedence relationships, which
   utilize resources to transform inputs into outputs with the
   purpose of satisfying customer requirements

                            Resources


                              Process


    Suppliers   Inputs                      Outputs   Customers



                                                                     4
Process Types and Hierarchies

1. Individual processes
    – Carried out by a single individual

                             Make up

2. Vertical or Functional processes
    – Contained within one functional unit or department

                             Make up

3. Horizontal or Cross Functional processes
    – Spans several functional units, departments or
      companies


                                                           5
Process Types and Hierarchies

Core cross-functional processes often have highest
improvement potential
 • Core processes – essential for meeting market place demand
   through a specific strategy
 • Especially high improvement potential if a significant
   amount of non-manufacturing/service related activities
 • Reasons
      –   Difficult to coordinate
      –   Have not kept up with improvements in manufacturing
      –   Difficult to detect waste and inefficiencies
      –   Often as little as 5% of the time considered adding customer value
      –   Customers more likely to abandon business because of “poor”
          service than “poor” products
                                                                         6
Components of the Process Architecture

      Inputs and Outputs           Information structure




                        Process
 Flow units                                       Resources
                      Architecture




                      The network of
                   activities and buffers



                                                              7
Components of the Process Architecture
Inputs and Outputs
• Establish interaction between the process and its environment
• Identify the process boundaries ⇒ easy to identify the Input consumed
  from the environment in order to produce the desired Output
• Process inputs and outputs can be
    – Tangible (Ex. raw material, cash, products, customers)
    – Intangible (Ex. Information, time, energy, services)
Flow units
• A flow unit is a transient entity or a job that proceeds through the network
  of activities and buffers and exits the process as a finished output
• Typically, the identity of a flow unit changes across the process
• Examples of common flow units: materials, orders, files, documents,
  customers, products, cash, transactions…
• Flow rate – The number of jobs flowing through the process per time unit
                                                                           8
Components of the Process Architecture
The network of activities and buffers
• The work performed on a job moving through a process can be divided
  into an ordered sequence of activities
• The buffers represent storage or waiting points where the job waits before
  moving to the next activity (queues, waiting rooms, etc.)
• Different types of jobs ⇒ different paths through the network
• Defining activities is crucial in process analysis
    – Tradeoff between process and activity complexity



  Process Complexity




                         Individual Activity Complexity
                                                                         9
Components of the Process Architecture

Resources
• Tangible assets utilized to perform activities in a process
• Can be divided into:
     Capital assets – real estate, machinery, equipment, IT systems…
     Labor – people and their knowledge and skills
• Resources are utilized while inputs are consumed

Information structure
• Specifies the information required for making decisions and
  performing activities in a process
• Limited information availability is a common cause for process
  inefficiencies
    – Information enables coordination!

                                                                    10
Workflow Management Systems

• Management of administrative processes in the field of
  Information Systems is often referred to as workflow
  management
• Workflow management systems
    –   Control actions taken on documents moving through a business
        process
    –   Workflow management software/systems are used to control
        who does what to a specific document
• Using our comprehensive process definition
   ⇒ Process = Workflow



                                                                  11
The Essence of Business Process Design

      “How to do things in an efficient and effective way”

 • An efficient process which does not deliver customer value is useless

          A well designed process does the right things, right!

 More formally…
 • BPD is concerned with configuring the process architecture to satisfy
   customer desires in an efficient way
     – Customers can be both internal and external
 • Internal customer requirements must be aligned with the desires of the
   external customers in the business strategy

We make a clear distinction between process design and implementation
                                                                           12
The Essence of Business Process Design
• BPD often most valuable when considering complex cross
  functional processes
    – Challenging coordination issues
    – Process inefficiencies often related to handing off work from one
      station or person to the next – introduces delays and errors
• The functional organization and division of labor paradigm
  dates back to Adam Smith and the late 1700’s
• Division of labor rationale: by focusing on fewer tasks ⇒
    – Workers’ skill level goes up ⇒ work faster
    – No time lost when workers switch between tasks
    – Workers well positioned to help develop better techniques and tools
• Drawback: more complex coordination issues when
    – More complex products and services
    – Customers demand more variety                                       13
Example 1
 Explanation of existing claims process

1.   Client notifies a local agent that she wishes to file a claim. She is given a claims
     form and is told to obtain a cost estimate from a local glass vendor.
2.   When the claims form is completed the local agent verifies the information and
     forwards the claim to a regional processing center.
3.   The processing center logs the date and time of the claim’s arrival. The data is
     entered into a computer-based system (for record keeping only) by a clerk. The
     claim is then placed in a hard copy file and passed on to a claims representative.
4.   a) If the claims representative is satisfied with the claim it is passed along to
     several others in the processing chain and eventually a check is issued and sent
     to the client.
     b) If there are problems with the claim the representative mails it back to the
     client for necessary corrections.
5.   When the client receives the check she can go to the local glass vendor and
     replace the glass.

                                                                                     14

                                                             15
Linking BPD to overall Business Performance
  • Overall business performance?
     – Detailed definition is company specific
     – Generally, performance must be measured against the stated objectives

    Profit maximizing firms                     Non-profit organizations
 Overarching objective is usually to          A common objective is survival and
maximize long term shareholder value         growth while satisfying customer needs


      Maximize revenues and                   Must use resources efficiently while
         minimize costs                        understanding customer needs


                   Satisfying customer needs in an efficient way


                        Well designed business processes

                                                                                16
