organization
* Important elements in managing processes
- Process design
- Continuous (incremental) improvement
- Control systems

The Power of Adopting a
———__Process View _____
* Weaknesses of the functional org. and division of labor
paradigm
- Focus on skills and resource utilization rather than work output
- Reward systems tailored for the functional unit not the overall firm
- Group behavior and cultures fostering an “us versus them”
mentality
- Decentralization = “firms within the firm” with their own agenda
* Strengths of a process view
~ Creates focus on work output = reduced risk for sub-optimization
~ Leads to transparency of how contributions of individual workers
fit into the “big picture” > encourages involvement and
empowerment
- Helps break down barriers between departments
Creates a sense of loyalty towards the process to balance the
loyalties within the functional units

* Need someone in charge to make things happen
* Responsibilities of a process owner
- Accountability and authority for process operations and
improvements
- Facilitate problem solving and make sure corrective action is
taken
- Mediate between line managers with overlapping authorities
* Guidelines for assigning process ownership
- Manager with most resources or most work invested in the
process
- Manager that is most affected if the process fails
- Process owner must have high enough position to see how the
process fits into the “big picture”, needs clout to solve functional

Phase I: Initialization
Analyzing Process Boundaries and
Interfaces
* Process Boundary defines the process entry and exit
points where inputs flow in and outputs flow out
- Provides a clear picture of the process scope
- Defines the external interfaces
* Internal interfaces
- Hand-off points within the process boundaries
- Most critical where the process crosses functional or
organizational borders
* Most process inefficiencies are related to insufficient
interface communication (= lack of coordination)
- Important to identify critical interfaces early on
صفحه 8:
The Customer-Producer-Supplier
(CPS) model
* Useful approach for resolving interface related problems
+ Applying the CPS model to all critical interfaces = adopt a
view of the process as a chain of customers
- Coordination achieved by understanding internal & external
customers
- Involves negotiation and agreement between all parts

» Objective:
Y Understand and document the process workflow
Y Facilitate communication and understanding of process
operations
Define the process
* Documentation of work content in individual activities
- Usually in terms of verbal descriptions
Y Operating procedures or Standard Operating Procedures (SOP)
* Documentation of process flows
- Usually a flowchart based method
¥ Combination of verbal and graphical description
* Common information gathering techniques
Interviews with people working in the process (group or

Phase III: Control (1)
>» Objective:
Y Establish a system for controlling the process and
providing feedback to the people involved
Establish Control Points
* Control points are activities such as
- Inspection, verification, auditing, measuring, counting...
- Usually considered business value adding
٠ Without control points and a control system the
only way of assessing process performance is
customer feedback
= The process ends up in a reactive mode
= Poor quality is discovered too late
* Location of control points is determined by
- Criticality - impact on customer satisfaction
- Feasibility - physically and economically possible

صفحه 11:
Phase III: Control (II)
Develop and Implement Measurements
* Involves answering the questions
1.What is to be measured and controlled (Ex. FedEx)?
2.What is currently measured (available data)?
3.Can a business case be made for a new measurement system?
4.What is the appropriate sampling method, sampling size and
frequency?
* Measurements should be meaningful, accurate and timely
~ Statistical and graphical tools needed to turn data into
information.
* Five measurement categories: Measures of...
- Conformance (to given specifications)
~ Response time (lead-time, cycle time)
~ Service levels (degree of availability)
- Repetition (frequency of recurring events such as rework)
- Cost (Quality, PAF, internal and external failure costs)

صفحه 12:
Phase III: Control (IID
Performing Feedback and Control
* Of critical importance for stabilizing and improving the
process
* Objectives of control/corrective action are
- Regulation to maintain a certain performance level
~ Improvement aiming at reducing variability or raising the
average performance level
¢ Feedback is an important enabler for corrective action
~ People in the process need to understand how their actions
affect the overall process and its performance
~ Feedback should be performed in a constructive - not punitive -
manner
* Constructive feedback
~ Makes people feel that they matter
~ Encourages involvement and commitment

_Six Sigma Quality Programs
* Six Sigma is originally a company wide initiative at
Motorola for breakthrough improvement in quality and
productivity
- Launched in 1987
~ Rendered Motorola the Malcom Baldridge National Quality Award
1988
* The ongoing success of Six Sigma programs has attracted a
growing number of prestigious firms to adopt the approach
- Ex. Ford, GE, AMEX, Honeywell, Nokia, Phillips, Samsung, J.P.
Morgan, Maytag, Dupont...
> Broad definition of Six Sigma programs
“A company wide strategic initiative for process improvement in
both manufacturing and service organizations with the clear
objective of reducing costs and increasing revenues”
~ Fierce focus on bottom line results

Technical Definition of Six
* Reduce the variation of every individual process to render no
more than 3.4 defects per million opportunities
* Assuming the process output is normally distributed with mean

The Six Sigma Cost or Efficiency
¢ Oriented around the dimensions of variation, cycle
time & yield
Variation
* Can be divided into two main types
1.Common cause or random variation
2. Special cause or non-random variation
* Non-random variation
- Relatively few identifiable root causes
- First step in reducing the overall variation is to eliminate
non-random variation by removing its root causes
* Random variation
- The result of many different causes
- Inherent in the process and can only be affected by
changing the process design

The Six Sigma Cost or Efficiency
Variation (cont.)
* Important concepts in understanding the impact of
variation
- Dispersion
~ Predictability
- Centering
* Dispersion
- Magnitude of variation in the measured process characteristics.
* Predictability
- Do the measured process characteristics belong to the same
probability distribution over time?
- For a predictable process the dispersion refers to the width of the
pdf.
* Centering
- How well the process mean is aligned with the process target
value.

ee
Variation (cont.)
* Ideally the process should be predictable, with
low dispersion, and well centered
¢ Standard approach for reducing variability in
Six Sigma programs
1. Eliminate special cause variation to reduce
overall dispersion and improve predictability
2. Reduce dispersion of the predictable process
3. Center the process to the specified target
¢ Six Sigma use traditional tools for quality and
process control/analysis
- Basic statistical tools for data analysis
- The 7 QC tools

صفحه 19:
The Six Sigma Cost or Efficiency
Cycle time and Yield
* Cycle time (lead-time, response time)
- The time a job spends in the process
* Yield (productivity)
- Amount of output per unit of input or per unit time
¢ Improvement in cycle time and yield follow the
same tactic as for variation
- Gain predictability, reduce dispersion and center to
target
¢ The target is usually broadly defined as
- Minimize cycle time and Maximize yield
* Six Sigma principle
- Improvement in average cycle time and yield should not
be made at the expense of increased variation

Six Sigma Success Factors
* The bottom line focus and big dollar impact
- Encourages and maintains top management commitment
* The emphasis on - and consistent use of - a unified and
quantitative approach to process improvement
~ The DMAIC methodology provides a common language so that
experiences and successes can be shared through the
organization
~ Creates awareness that decisions should be based on factual data
* The emphasis on understanding & satisfying customer
needs
- Creates focus on doing the right things right
- Anecdotal information is replaced by factual data
* The combination of the right projects, the right people
and the right tools
- Careful selection of projects and people combined with hands on
training in using statistical tools in real projects

Introduction to
* Business Process Reengineering (BPR)
- One of the buzzwords of the late 80’s and early 90’s
- “...achieves drastic improvements by completely
redesigning core business processes”
* BPR has been the subject of numerous articles and
books; classical examples are:
Y “Reengineering Work: Don’t Automate, Obliterate”,
Michael Hammer, Harvard Business Review, 1990
Y “The New Industrial Engineering”, Davenport and Short,
Sloan Management Review, 1990

* Xerox redesigns its order fulfillment process and improves
service levels by 75-97% and cycle times by 70% with
inventory savings of $500 million
* Detroit Edison reduces payment cycles for work orders by

Failures
٠ An estimated 50-70% of all reengineering projects
have failed
¢ Those that succeed take a long time to implement
and realize 25
صفحه 26:
Reasons for BPR Failures
¢ Lack of support from senior management
* Poor understanding of the organization and the infrastructure
+ Inability to deliver necessary technology
* Lack of guidance, motivation and focus
* Fixing a process instead of changing it
* Neglecting people’s values and beliefs
* Willingness to settle for marginal results
* Quitting too early
+ Allowing existing corporate cultures and mgmt attitudes to
prevent redesign
* Not assigning enough resources
* Working on too many projects at the same time
* Trying to change processes without making anyone unhappy
* Pulling back when people resist change
Etc...

What does it take to succeed
۳۳ with BPR?
* Hammer and Champy
- “The role of senior management is crucial.” و
* Empirical research indicates... :
- organizations which display understanding,
commitment and strong executive leadership
are more likely to succeed with process
reengineering projects.
* Common themes in successful
reengineering efforts
1. Firms use BPR to grow business rather than
retrench
2. Firms emphasize serving customers &
compete aggressively with quantity & quality
of products & services
3. Firms emphasize getting more customers, 27
more work and more revenues instead of

Brief History of BPR )1(
* Most agree that Michael Hammer laid the
foundation to the reengineering approach...
* ...But many factors influenced the birth and hype
around BPR
- The origins can be traced back to a number of
successful projects undertaken by management
consulting firms like McKinsey in the 80’s
- TQM had brought the notion of process improvement
onto the management agenda
- The recession and globalization in late 1980’s and early
1990’s stimulated companies to seek new ways to
improve business performance
Programs often aimed at increasing flexibility and
responsiveness 31
Middle management under particular pressure

* ...But many factors influenced the birth and
hype around BPR
- The Productivity Paradox (Stephen Roach)

When Should a Process be
Ree engineered? 01۲ مت
¢ Three forces are driving companies towards
redesign (The three C’s, Hammer & Champy,
1993)
¥ Customers
- are becoming increasingly more demanding
۷7 Competition
- has intensified and is harder to predict
Y Change
- in technology
- constant pressure to improve; design new
products faster
- flexibility and ability to change fast are
requirements for survival
33
صفحه 34:
When Should a Process be
i ?
* Useful questions to ask (Cross et al. (1994))
- Are customers demanding more for less?
- Are your competitors providing more for less?
- Can you hand-carry a job through the process
much faster than the normal cycle time (ex five
times faster)?
- Have your incremental improvement efforts been
stalled?
- Have technology investments been a
disappointment?
- Are you planning to introduce radically new
products/services or to serve new markets?
- Are you in danger of becoming unprofitable?
- Have cost-cutting programs failed to turn the
ship around? 34
- Are onerations heing meraed or consolidated?
صفحه 35:
What Should be Reengineered? (1)
* Processes (not organizations) are
reengineered
- Confusion arises because organizational units are
well defined, processes are often not.
¢ Formal processes are prime candidates for
reengineering
- Formal processes are guided by written policies;
informal processes are not.
- Typically involve several departments and many
employees.
- More likely rigid and therefore more likely to be
based on invalid assumptions.

1. Dysfunction
- Which processes are in deepest
trouble (most broken or

The Evolutionary Change
14
* Basic principle
- People directly affected by or involved in a change process
must take active part in the design and implementation of
that change
- Real change is achieved through incremental improvement
over time
* Change should come from within the current
organization
- Should be carried out by current employees and leadership
- Should be adapted to existing resources and capabilities =
flexible milestones
- Should be based on open and broad communication
¢ New processes and procedures are implemented
before introducing new IT systems

¢ Advantages of an evolutionary change tactic
compared to a revolutionary approach
- Less disruptive and risky
- Increases the organization's ability to change

- Vision must be kept alive and adjusted over time as
external market conditions change

صفحه 51:
The Revolutionary Change
* Based on the punctuated equilibrium paradigm
- Radical change occurring at certain instances
- Long periods of incremental change in between
* Revolutionary change
- Happens quickly
- Alters the very foundation of the business and its culture
- Brings disorder, uncertainty, and identity crises
- Needs to be top driven
- Requires external resources and new perspectives
- Involves tough decisions, cost cutting and conflict resolution
* The change team is small and isolated from the rest
of the organization
- Avoid undue influence from current operations
- Communication with people in the process is on a “need to
know” basis

صفحه 52:
The Revolutionary Change
¢ Advantages with a revolutionary implementation
approach
- Drastic results can be achieved quickly
- If successful, the ideal “blueprinted” design is put in place
* Disadvantages with a revolutionary change tactic
- Very strenuous for the organization
High probability for failure
- Diverts top management attention from the external
marketplace
- Goes against core values of many organizations
¥ Empowerment
Y Bottom-up involvement
¥ Innovation
- Secrecy creates uncertainty about the future roles of
individual employees = resistance to change
