Abstract
Today’s businesses are competing increasingly on time and quality.
Companies cannot survive if they fail to obtain competitive
advantages by producing high quality products and services in
shorter throughput time and quicker inventory turnover. Some of the
management techniques used in manufacturing organizations may
not be appropriate for service organizations (Siha, 1999). Most
manufacturing and service organizations seek to make a larger profit
at the present and in the future. However, constraints on
manufacturing and service organizations prevent the organization
from making a higher level of profit. Some authors agreed upon a
management methodology called the theory of constraints (TOC)
which views resistance as a necessary and positive force. Literature
on change management contains numerous prerequisites for
successful change, with a predominantly negative view on the issue
of resistance to change. Recent change efforts in many organizations
and especially multinationals, have been geared towards
downsizing; energizing; empowering; total quality management; and
now business process re-engineering (Sinclair, 1994). Hence, the
TOC philosophy has been developed to be applied to everyday
operations decisions as well as to continuous improvement effort. To
take advantage of resistance, a "whole-system" view is required as
well as an appreciation for the true "root-cause" problems. The TOC
provides a view and set of powerful tools that can be used to not only
address resistance but also use it to enhance the solution beyond the
original concept (Patrick, 2011). As a result of applying TOC’s
Thinking Processes to countless organizations over three decades,
generic TOC solutions have emerged that have applicability across
all organizations, both for-profit and not-for-profit. To this day these
applications continue to evolve, resulting in more and more
significant and sustainable overall and bottom line performance
improvements were implemented (Goldratt, 2009). The objective of
this paper is study the relation between resistance to change and
TOC.

Introduction
Change is a way to tell people to adopt new ideas in dealing with different aspects of
their lives. Of these aspects is introducing “new ways of doing things, new ways of
seeing themselves, their roles and their interactions with others inside and outside the
organization” (Sinclair, 1994). For this reason Sinclair (1994) proposes that managers
have to understand the influence of change on their employees and try to solve
problems that may occur as a result to this change.
People have been widely recognized as a natural change-resistant. Nevertheless,
management gurus and consultants within the organizational change management
area have developed over the years various approaches aiming at elevating employees'
performance within organization (Sinclair, 1994). This point was introduced by
Ragsdell (2000) who stated that the change done in organizations is relative; as it
could be comprehended differently from one employee to the other within the same
organization. It could be “facing new challenges, of gaining promotion and of
furthering their career. Other may see it as a reduction in responsibility, a loss of
status or even an enforced career break”. Sinclair (1994) agrees with Ragsdell (2000)
that change is relative and differs from one person to the other, which makes it
important to analyse problems that may occur from implementing change from
different points of views.
Ragsdell (2000) adds that organisational change mostly intends to change the
organizational state from the undesirable “before” to an improved or desirable “after”
state. Sinclair (1994) mentioned that organizational change faces resistance which is
mostly caused because of stereotypes and perceptions that are adopted by employees
within an organization. These factors should be studied by managers in order to find
ways to overcome and implement an effective change process. However, Oakland and
Tanner (2006) agree with Sinclair (1994) on the idea of resistance to change and list
enablers and factors of resistance to change. Islam and El-Araby (2007) stated that it
could be noticed that "resistance to change" is a very important factor in hindering the
process of change.
So, having introduced the resistance to change as a core barrier to change
management, the author in the next section continues by creating awareness about
resistance to change in more details.
Literature Review - Resistance to Change
Mabin et al. (2001) stated that some view resistance as an unavoidable and natural
behavioural response to the perceived threat of change. It may be seen to be
politically motivated and part of a coordinated campaign of class struggle, or to be a
constructive counter-balance to organisational change, or as the manifestation of
difficulties in cognitive restructuring. In most reports in the literature, resistance is
seen to be problematic, something to be managed and "overcome'' to ensure the
success of change. Schermerhorn (1989) has suggested strategies for "dealing with''
resistance, consistent with this view of resistance as being undesirable. It is much less
often recognised as something to be utilised to support the success of change.
3
Resistance to change is acknowledged as being a fundamental block to change, and a
prime reason why change does not succeed or get implemented. Resistance to change
is everywhere in nature (Mabin et al., 2001). It can be defined as an expression of
reservation which normally arises as a response or reaction to change (Block, 1989).
Mabin et al. (2001) add that resistance is caused by a number of factors, such as:
Individual factors: personality factors (high need for control, locus of control, need
for achievement etc.); attitudes based on previous experiences of change.
Group factors: group cohesiveness, social norms, and participation in decision
making.
Organisational factors: threats presented by the unknown; challenges to the status
quo; workload consequences.
They add that there are many reasons why people inside organisations resist change;
indeed, it is possible for the entire system which the organisation represents, to be
resistant to change if the preparation for change has not been carried out in a manner
that does not correctly prepare the organisation for it. Kanter (1985) has been
identified ten types of resistance, see Table 2.
Table 2: Factors Causing Resistance to Change
Cause Outline
Fear of the unknown Being uncertain about the nature of a change, feeling that you do not know
what is going on and what the future is likely to hold
Loss of control Feeling that the change is being done to you, not by you, worrying that you
have no say in the situation and the events taking place
Loss of face Feeling embarrassed by the change and viewing it as a testimony that the
way you have done things in the past was wrong
Loss of competency Feeling that existing skills and competencies will no longer be of any use
after the change
Need for security Worrying what your role will be after the change
Poor timing Being caught by surprise with a change that has been sprung on you, or
being asked to change at a time when you already feel overworked
Force of habit Not liking to change existing ways of doing things, feeling comfortable in
existing routines and habits
Lack of support Lacking important support from direct supervisors and/or organisation, not
having the correct resources to properly implement the change
Lack of confidence Lacking in personal confidence that things, once changed, really will be
better than before
Lingering resentment Being recalcitrant because of a lack of respect for the people involved and/or
because of anger over the way you have been treated during past change
efforts

Consequently, Deming (1986) stated that staying the same is no longer an option and
those organizations must change to continually improve. Organizations must learn
quickly to adapt to changing business environments. Also, Mabin et al. (2001)
declared that some authors agreed upon a management methodology called the theory
of constraints (TOC) which views resistance as a necessary and positive force.
Subsequently, it is important to study TOC as a tool to eliminate resistance to change
in organizations

Literature Review – Theory of Constraints (TOC)
Origin
Since the early 1970s, three important approaches have evolved for companies to
achieve competitive advantages, each challenging old assumptions and ways of doing
things. These are materials requirements planning (MRPI and MRPII), just-in-time
(JIT), and theory of constraints (TOC) Rahman (1998).
TOC developed primarily by Dr Eliyahu M. Goldratt, although considered in the
1970s in a manufacturing context as a scheduling algorithm, Mabin and Balderstone
(2003) stated that TOC has now been developed into a powerful and versatile
management theory, as a suite of theoretical frames, methodologies, techniques and
tools. They add that it is also being applied to situations outside the manufacturing
context, including distribution, marketing, project management, accounting – in fact
any situation involving change to a system.
TOC named before as Optimized Production Timetable in (1979) then changed to
Optimized Production Technology (OPT) in 1982, finally named TOC at the
beginning of 1987 signalled a major change in emphasis, first, from rule-based
scheduling logic to the applications software tool OPT and later to a focusing/iterative
process of ongoing improvement. The addition of the thinking processes (TPs) in the
1990s broadened the scope to an organization wide perspective and the changes in
people’s thinking and behaviours required in any change process. While many of the
early principles foreshadowed general and behavioural issues, the later frameworks
have made these issues more apparent and more amenable to managerial analysis and
action (Mabin and Balderstone, 2003).
Goldratt and Cox (1984) proposed the TOC as a scientific process for generic
problem solving, particularly in manufacturing industries and it has been developed
over the past 20 years (Bradbury-Jacob and McClellend, 2001; Dettmer, 1997; Houle
and Burton-Houle, 1998; Kendall, 1998; Mabin and Balderstone, 2003; Scheinkopf,
1999). Goldratt and Cox (1984) claimed that the focus of management was on
measurement and rewards of “local efficiency” rather than highlighting “systems
efficiency” and its contribution to the ultimate goal. TOC is now a systemic problem-
structuring and problem-solving methodology which can be used to develop solutions
with both intuitive power and analytical rigour in any environment (Mabin and
Balderstone, 2003).
Definition
The TOC is an intuitive framework, developed by Goldratt (1990), for managing
organizations. Motwani et al. (1996) mentioned that "Implicit in the TOC framework
is the desire to improve performance of organizations continually, through a process
of ongoing improvement". Siha (1999) believed that TOC is "an overall management
philosophy that recognizes that the constraint on any system restricts the maximum
performance level the system can obtain in relation to its goal". Mabin and
Balderstone (2003) stated that TOC is "a multi-faceted systems methodology that has
been progressively developed to assist people and organizations to think about
problems, develop breakthrough solutions and implement those solutions
5
successfully". Motwani et al. (1996) said that the TOC "emphasizes the importance of
defining and understanding the global goal of the organization as a condition for
success". This concept is based on the assumption that resources available for
managers and organizations are limited, and should therefore be directed towards a
well defined and focused goal.
Purpose
Although conceived in the 1970s in a manufacturing context as a scheduling
algorithm, TOC has now been developed into a powerful and versatile management
theory, as a suite of theoretical frames, methodologies, techniques and tools. It is now
a systemic problem-structuring and problem-solving methodology which can be used
to develop solutions with both intuitive power and analytical rigour in any
environment (Mabin and Balderstone, 2003).
The core idea of TOC is that every organization has at least one constraint that
prevents management from achieving the goal of the organization to a larger degree.
TOC develops a set of methodologies to identify and optimize such constraints. This
methodology has been used as a guideline for the application of TOC to various areas
including production, distribution, project scheduling and control (Sheu et al., 2003).
Mabin and Balderstone (2003) mentioned that the TOC approach epitomizes systems
thinking: a philosophy that recognizes that the whole is much more than the sum of its
parts, and that a complex web of interrelationships exists within the system. As
Goldratt (2000) stressed, “We must never lose sight of the global picture”. Though
everyone recognizes this obvious truth, many of the day-to-day business practices
lead directly away from this objective. One of the distinctive features of Goldratt’s
systems perspective is to realize that there are always limitations to the performance
of the system of interest, and that despite the complex web of relationships, these
limitations are caused by just an element in the system which he terms the
“constraint”. This constraint may be a physical constraint such as a machine with
limited capacity or raw material, but more often it is either a policy or behavioural
constraint. Policy constraints occur when the environment within which that a
company exists changes while the policies of the company remain unchanged. Most
significantly, policy constraints are usually under the control of the organization
management. On the other hand, behavioural constraints occur when performance
measures or policies lead to behaviours that are changed, are ingrained and constrain a
system’s performance: “Old habits die hard” (Mabin and Balderstone, 2003).
Goldratt and Cox (1984) suggest that the main constraints in organizations are often
not physical constraints (resource capacity, markets or vendors) but policy constraints.
Applications
Pegels and Watrous (2005) claimed that TOC views manufacturing
processes/organizations as “chains”, wherein the entire system is only as strong as its
weakest link. They added that the purpose of TOC is to identify the weak link
(constraint) within an organization and to strengthen this link to the point where it is
no longer the limiting factor in determining the strength of the chain (or organization).
Expanding on this line of thinking, no matter how strong the chain has become, it will
always have at least one link that is not quite as strong as the others. For this reason,
6
TOC can be thought of as a continuous improvement process, because no matter how
well an organization performs; there will always be at least one constraint that limits
the organization from becoming a little better. The TOC process emphasizes the need
to maximize throughput and focuses on identifying and managing the constraints that
can reduce the amount of throughput a company is able to achieve. Using the TOC
process, the objective of management is reaching a point where the system’s
constraint lies outside the production arena. An example of such a situation occurs
when all orders are completed on time and there is a shortage of incoming orders.
Malonis and Cengage (2000) stated that TOC is practiced in many different
industries, including automotive, computers, telecommunications, furniture, retail
food, consumer goods, and apparel. Practitioners have ranged from Fortune 500
companies like Procter & Gamble Co. and General Electric Co. to small local
businesses.
The TOC literature covers theory and practice and addresses wide variety of issues
relating to accounting, scheduling, performance measurement, product mix, quality,
and project management and application areas. In the literature reviewed, several
instances of application to non-manufacturing, administrative or service functions are
mentioned (Mabin and Balderstone, 2003). The organizations reported on include
some of the world’s largest and most successful organizations: Boeing, General
Motors, Ford Motor Company, Lucent Technologies, to name just a few. On the other
hand, there are reports of applying TOC in very small organizations as well (Mabin
and Balderstone, 2003). As for the manufacturing sector, there is a significant series
of applications in the aerospace, apparel, automotive, electronics, furniture,
semiconductor, steel and heavy engineering industries (Mabin and Balderstone,
2003).

Concept
The concept of the TOC can be summarized as: Every system must have at least one
constraint. If it were not true, then a real system such as a profit making organisation
would make unlimited profit. A constraint therefore, “is anything that limits a system
from achieving higher performance versus its goal” (Goldratt, 1988). And the
existence of constraints represents opportunities for improvement. Contrary to
conventional thinking, TOC views constraints as positive, not negative. Since
constraints determine the performance of a system, a gradual elevation of the system’s
constraints will improve its performance (Rahman, 1998).
Rahman (1998) stated that TOC has two major components. First: philosophy which
underpins the working principle of TOC. It consists of the five focusing steps of on-
going improvement, the drum-buffer-rope (DBR) scheduling methodology, and the
buffer management information system, and is usually referred to as TOC’s
“logistics” paradigm which also include continuous improvement (ECE diagrams).
Second component of TOC is a generic approach for investigating, analysing, and
solving complex problems called the thinking process (TP). In addition, TOC
prescribes new performance measurements which are quite different from the
traditional cost-accounting system.
1. Philosophy
By taking the TOC philosophy into consideration, improvements in performance can
only be achieved by focusing on system constraints.
a. Five focusing steps of on-going improvement
Goldratt and Cox (1992) suggested five steps to achieve this focus. These steps are
generic in that they can be applied to any system, including service businesses which
are summarised in Figure (1). These five steps are:
1. Identify the system constraint (weakest link). A system cannot be maintained at
maximum performance unless the system constraints are determined so as to
design the control mechanisms appropriate to the constraints.
2. Decide how to exploit the system constraint. Achieve the best possible output
from the constantly. Removing the limitations that impede the flow, and reducing
non-productive time, so that the constraint is used in the most effective way
possible.
3. Subordinate the non-constraint. Link the output of other operations to suit the
constraint and make sure the rest of the system is enabled to help, not detract
from its ability to achieve step 2.
4. Elevate the system's constraint. After completing the above steps, more resources
must be provided to achieve further improvements in the system performance.
5. If a constraint has been “broken” in the above steps, return to step 1. Assess to
see if another operation or policy has become the system constraint. This is
because after a constraint is changed, new system constraints may surface. Return
to step 1 to identify new constraints.

Figure 1: Five Steps to Achieving Ongoing Improvement
Noreen et al. (1995) stated that the implementation of the five focusing steps to a
typical production environment can quickly yield substantial improvements in
operations and in profits. However, this process of continuous improvement takes the
production operations to a point where the constraint shifts from factory floor to
market. In such a case, constraint could be market demand (insufficient demand)
which is a managerial/policy constraint rather than a physical constraint. Policy
constraints are generally difficult to identify and evaluate, and frequently require
involvement and cooperation across functional areas.
b. Scheduling process (Drum-Buffer-Rope or DBR)
The TOC has a unique method of scheduling process with constraints, called Drum-
Buffer-Rope or DBR. For a system to keep the maximum performance, it must be
designed in a way that makes so capacity constraints within it operate at their peak
capacity (Levinson, 2007).
The Drum is the capacity constraint. The capacity constraint sets the pace for
the system as a drum sets the pace for marching soldiers.
The Buffer isolates the capacity constraint from the negative effects of the rest
of the system.
The Rope ties raw material release to the capacity constraint buffer to assure
that inventory is at the lowest level that will maintain capacity constraint
performance at maximum.
c. Logistics Paradigm (buffer management information system)
The logistics branch is everyday operations. This method is to classify plants based on
the product and the process flow. The "V'' plant has very few raw materials and many
final products. The "A'' plant has many raw materials and a limited number of final
products. The "T'' plant has many final products that are assembled in many different
ways from a limited numbers of components and subassemblies.
Identify the system’s constraint (s)
Decide how to exploit the constraint (s)
Subordinate everything else to the above decision
Elevate the system’s constraint (s)
If in the previous steps the constraint is broken, go back
to step 1, but do not allow inertia to cause a system

This analysis is very important in recognizing the type of problems, issues and
concerns associated with each type.
d. Continuous Improvement (ECE diagrams)
The process of developing these diagrams forces managers to think about the true
causes of problems. Hence, the Utilizing critical thinking which is the root cause of a
problem is identified. Consequently, a plan is developed to eliminate the root cause
rather than treat the problem symptoms. This approach answers three questions, what
to change, what to change to, and how to change.
Lubitsh et al. (2005) stated the first three steps would allow for dramatic improvement
in throughput, without extra money/resources. This contradicts a common
management assumption that most improvement in performance requires extra
money/resources.
Reviewing the literature of TOC in the manufacturing sector supports a view that
TOC can be associated with an increase in productivity for both individuals and
organisations. In particular, TOC has simultaneously increased throughput and
reduced both operating expenses and inventory (Rand, 1984; Meleton, 1986; Chase et
al., 1998; Bushong and Talbott, 1999; Miller, 2000).
Researchers such as Vollmann (1986), Massood (1998), Tollington (1998) and
Michalski (2000) examined the effectiveness of identifying and exploiting the
bottleneck. They reported the following benefits. One, by identifying the bottleneck in
advance you can reduce the variability through reducing the material ordered into the
system. Two, efforts specifically targeted at the “buffers” located before a bottleneck
ensure that material going through the bottleneck does not have to be “reworked”.
Three, scheduling the bottleneck resource results in better use of the bottleneck area.
It was this area that paid the greatest dividends in terms of net profit. Four, having a
buffer before the constraint ensures that the bottleneck is less vulnerable to random
disturbances in workflow.
2. Thinking Process (TP)
In 1994, Goldratt developed a generic approach to address policy constraints and
create breakthrough solutions for them using common sense, intuitive knowledge and
logic. This procedure is referred to as the thinking process (TP). According to Noreen
et al. (1995) “the TP may be the most important intellectual achievement since the
invention of calculus”. And according to Goldratt (2009) "the TP are a set of tools
and processes that allows an individual or group to solve a problem and/or develop
an integrated strategy using the rigor and logic of cause-and-effect, beginning with
the symptoms and ending with a detailed action plan that coordinates the activities of
all those involved in implementing the solution".
Furthermore, Patrick (2011) stated that the TOC TP are logical thinking and
communication tools which can be used in separate situations and also together can
form a coherent problem-solving and change management process.
11
He adds that "they are used for the construction of solutions to problems as well as to
facilitate communication, collaboration, and consensus among those that must be
involved in its resolution".
Moreover, Goldratt (1994) declared that while dealing with constraints managers are
required to make three generic decisions: Decide what to change, decide what to
change to, and decide how to cause the change. The TP prescribes a set of tools,
which basically are cause-and-effect diagrams, to get answers to these questions. The
questions, associated tools and their purposes are summarised in Table 3.
Table 3: TP Tools and their Roles

What to change to? Identify core problems Current reality tree
What to change to? Develop simple, practical
solutions
Evaporative cloud,
Future reality tree
How to cause the change? Implement solutions Prerequisite tree, Transition tree Source: Rahman (1998)
3. Performance measures
To understand TOC and to apply it effectively to an organization, one must
completely understand the goal of the organization (Malonis and Cengage, 2000).
Goldratt and Cox (1992) emphasized that the goal of any organization is to make
money. It is important therefore to create a set of measurements that honestly and
accurately allow an organization to monitor its performance as it relates to its goal.
With TOC, the "cost world" is replaced by the "throughput world," which is driven by
these three key components (Figure 2):
1. Throughput (T): The rate at which the system generates money through sales
(product or service).
2. Inventory (I): All the money invested in purchasing things the system intends to
sell which would include plant, property, and equipment.
3. Operating Expense (OE): The money spent to convert inventory into throughout.
Figure 2: Definitions of Throughput, Inventory, and Operating Expense
Using these measurements in combination with TOC "scientific" problem-solving
methods allows management to focus on critical issues and root causes rather than
symptoms of problems. Although these measures are different from the traditional
ones they can be converted to more traditional measures with simple mathematical
operations (Finch and Luebbe, 1995). For example:
Net profit = throughput - operating expense
Inventory turns = throughput /inventory
11
Productivity = throughput /operating expense
Throughput (T) and operating expense (OE) are regarded as appropriate measures for
service businesses. However, inventory (I) as defined above may not be appropriate
for all of them. The measures T, I, and OE are global indicators of system
performance. Organizations should work to increase overall system T and to reduce
the I and OE at the same time.
Due to the importance of resistance to change as mentioned before through
introducing TOC as a tool to eliminate resistance to change in organizations. The
following section shows TOC tools to overcome resistance to change.
Overcoming Resistance to Change through TOC
Mabin et al. (2001) outlines ten causes of resistance to change and explain how each
of these is dealt with within the TOC framework to help recognise and overcome
resistance, as shown in Table 4.
Table 4: Resistance to Change Factors and TOC Tools to Help Utilise Them
Cause Outline TOC Tools Fear of the unknown Being uncertain about the nature of a
change, feeling that you do not know
what is going on and what the future is
likely to hold

viewing it as a testimony that the way
you have done things in the past was
wrong
Usually a problem is due to
conflict (e.g. over priorities)
CRT and EC can help

change
FRT and NBR (see also loss of
face)
Poor timing Being caught by surprise with a change

respect for the people involved and/or
because of anger over the way you have
been treated during past change efforts

these issues
Source: Mabin et al. (2001)
The above shows that TOC addresses many of the "soft" or emotional issues
surrounding change. TOC works by giving credibility to these issues, validating them
in people understanding and providing ways of dealing with them through buy-in and
reassurance.
Goldratt (2009) confirmed that TOC has developed a process based on the psychology
of change that acknowledges and systematically addresses the questions people
intuitively ask when evaluating a change.
a. Is the right problem being addressed - mine?
b. Is the general direction that the solution is heading a good one?
c. Will the solution really work to solve the problems and what’s in it for me?
d. What could go wrong? Who might get hurt?
e. How the heck are we going to implement this thing?
f. Are we really up to this? Do we have the leadership and the commitment to pull
this change off successfully?
If these questions aren’t answered frankly and effectively with both the people who
must implement the change and those who will be affected by it, the proposed change
will not have the buy-in and support to succeed. Like most changes, no matter how
great the idea or tremendous the value, the strategy and tactics are doomed from the
outset. The three questions, What to Change?, What to Change To?, and How to
Cause the Change?, provide the framework for what’s called the TOC Thinking
Processes. Fortunately, it has been shown that resistance to change can be understood
in terms of a series of six layers that consistently and regularly appear.
Patrick (2011) acknowledged that these layers are associated with the three basic
questions for change and their objectives and have been identified as shown in Table
5.
Patrick (2011) declared that while not all of these “layers of resistance” arise all the
time, when they do they tend to do so in the order listed. Or at least, they should be
addressed in that order. After all, there is no point in figuring out how to overcome
obstacles and implement a solution (Layer 5) if the idea of the solution itself is not
understood and accepted (Layers 2, 3, and 4). The existence of this consistency allows
for an equally consistent response, and therefore a systematic process to address it.

The ability to acquire necessary cooperation, collaboration, and even co-ownership is
enhanced if the change agent understands the layers of resistance that are usually
encountered, and the appropriate steps to take and tools to use within each when
communicating the proposal. But the benefit of addressing the layers in the right way
goes far beyond simply overcoming resistance.
What is often not appreciated is that this same resistance is an invaluable source of
improvements to the original proposal. You can take advantage of this benefit with a
logical process that is geared to do so, whether starting at the beginning of building a
solution or when communicating it for buy-in (Patrick, 2011).
For example, while carefully considering all the layers during the construction of a
solution will contribute to the completeness of the solution, layers 4 (“Yes, but…”)
and 5 (“We can't do it because…”) are particularly fertile ground for the enhancement
of a proposed solution. The same thing goes for layer 5 - obstacles to implementation.
If one can generate or identify more obstacles, the resulting implementation plan will
be that much more complete. Those obstacles will exist whether identified or not. It’s
a far, far better thing to identify and plan for them than to be surprised by them. Too
often, the developer of a proposal is so focused on the good things that will come
from it s/he will overlook or even worse, minimize the side effects and obstacles
(Patrick, 2011).

As a result of applying TOC’s Thinking Processes to countless organizations over
three decades, generic TOC solutions have emerged that have applicability across all
organizations, both for-profit and not-for-profit. To this day these applications
continue to evolve, resulting in more and more significant and sustainable overall and
bottom line performance improvements were implemented (Goldratt, 2009).
Conclusion:
In this paper the author has briefly reviewed the literature for change management,
resistance to change, theory of constraints, and demonstrated how to overcome resistance
to change through TOC. Finding that, organizational change faces resistance which is
mostly caused because of stereotypes and perceptions that are adopted by employees
within an organization. Concluding that "resistance to change" is a very important factor
in hindering the process of change. As resistance to change is acknowledged as being a
fundamental block to change, and a prime reason why change does not succeed or get
implemented. As well, resistance to change is everywhere in nature and it is caused by a
number of factors, such as: individual factors, group factors, and organisational factors.
Accordingly, organizations must learn quickly how to solve the resistance to change problems in order to adapt to changing business environments.
Some authors agreed upon a management methodology called the TOC which views
resistance as a necessary and positive force. So it was important to study TOC as a tool to
eliminate resistance to change in organizations. The TOC provides a view and set of
powerful tools that can be used to not only address resistance but also use it to enhance
the solution beyond the original concept. TOC has developed a process based on the
psychology of change that acknowledges and systematically addresses the questions
people intuitively ask when evaluating a change. TOC recognizes that the constraint on
any system restricts the maximum performance level that the system can obtain in
relation to its goal. It represents the synergy of systems, recognizing that the whole is
more than the sum of the parts. As a result of applying TOC’s Thinking Processes to
countless organizations over three decades, generic TOC solutions have emerged that
have applicability across all organizations, both for-profit and not-for-profit. To this day
these applications continue to evolve, resulting in more and more significant and sustainable overall and bottom line performance improvements were implemented.
