Lean supply chain management
1-Introduction
Supply chain is an established network of processes that starts from procurement of raw material;
conversion of raw material into final product and then distribution of that finished product to
customers. Over last two decades, the concept of lean supply chain management has gained great
importance from both academics and practitioners. To gain competitive advantages and to
survive in this dynamic environment firm are in need of delivering quality product with
minimum wastage of resources. Therefore the concept of lean Supply chain management is more
practical now a day’s then before it. Lean production is an integrated activity in SCM that is
aimed at achieving high volume production with minimum wastage of raw materials. It focuses
on improving the efficiency of processes on continuous basis, minimizing wastage and
eliminating almost all activities that does add any value in overall supply chain. Lean production
is considered a innovative way of thinking and thus it includes the integration of firms vision,
culture and strategy in such a way that it can serve the customer by providing high quality
product with in low cost and on short delivery Alabama Technology Network, 1998; Inman,
1999; Davis and Heineke,( 2005) cited by Agus& Hajinoor(2012).
Lean production is such a socio-technical system that is aimed on removing wastage by
minimizing supplier, customers and internal variability among firms operations. Lean production
is not only element that helps in achieving goals of Lean Supply Chain, it also includes product
development phase and aspects of distribution channel. Firms that want to implement LSCM
must also manage variable supply of product, processing time, demand and also manage
4
relationships with all parties in value chain. In lean production the major factors is to manage
external relationships rather than internals (Jurado, Fuentes, & Diaz. (2012)).
1.1 What is lean?
According to Ohno,1998;Monden,1983 Cited by Turner,Parry,&Mills(2010) Lean is derived
from Toyota motors who firstly introduced this concept by improving its processes not only
on shop but also in its design and development. Lean is a value system that is based on
company customers and chain partners. Womack and Jones in 1996 cited in
Turner,Parry,&Mills (2010) described the lean to eliminate wastage and increase efficiency.
They also identified its five principles that are:
Specify value
That is defined by customers in term of their satisfaction in shape of product for price
they are giving.
Identify value stream
Actions that are used to transform product and services through problem solving,
information technology etc.
Make the value flow
Reducing cycle time and batch size to make production more visible
Customer pull
Customers make demand about special product or service.
Pursuit perfection
Improvements will be made to make product or service perfect for customer.

2-Why leans supply chain is needed?
Lean supply chain improves the firm’s performance and also produce superior quality product to
customers. A comparison was conducted by Nightingale (2005) Cited in Zai, Manzouri, &
Rahm(2013) between conventional SCM practices and lean SCM practices. They also
highlighted numerous issues when companies shift from conventional to lean practices. Lean
SCM practices helps in achieving goal of superior quality with minimum resources. To survive
in this dynamic environment it is necessary for firms to adopt lean SCM practices to gain better
performance.
Characteristics Conventional practices Lean practices
1-Competition No competition among members Competition exists
Of supply chain
2-Role of supplier less involvement Greater involvement
3-Data interchange less interaction very frequent at
&interaction Operational level
4-Structure vertical clustered
5-Procurement personnel large limited
6- Outsourcing cost based strategic
7-Nature of interaction adversarial; zero sum cooperative: positive
8-Realtionship focus transaction focused mutually beneficial
9-Selection criteria low cost performance
10-Contract length short term long term
11- Price changes upward downward
12-Quality inspection-intensive designed in

Above table is complete comparison between conventional practices and lean practices. Lean
SCM is required because to superior quality, customer focused approach and cost effectiveness.
according to Zai, Manzouri, & Rahman(2013) In lean SCM there is collaboration at all that
improves firm’s process and performance in turn .
3-Benefits of lean supply chain management
Lean production is philosophy that is based on many practices like TQM, JIT to remove wastage
and improve performance. The use of Lean production practices results in following outcomes (
Hofer et al, 2012).
Improved operational performance
Higher quality
Lower inventories
Less lead
Improve financial performance
Increase collaboration between all parties
Less usage of raw material
Less cost of finished goods
4-Implementation of Lean SCM:
The term lean production is mainly associated with Toyota production system where it was
firstly implemented with JIT to improve quality and delivery time.

Health care sector:
An example from real life is implementation of lean processes in health care organizations.
Supply chain in hospitals is interconnected within its all departments. As due to less budget
available hospitals has to cut its budget by implementing lean manufacturing techniques. The
tendency to reduce supplies especially in hospitals is difficult task. Hospitals are notorious in
wastes and misuses of supplies that is less attention towards these issues and limited qualification
of professional in field of management. To implement lean practices is difficult task because
processes are more complex in hospitals and required a different combination of product and
services for each patient (Machado, &Vaccaro (2014) ).
The main changes that were made in health care organizations especially hospital are the
modification in work structure by building multidisciplinary teams and tasks are divided that
who is responsible for what. In this way administrative work is made more easily so time is left
for other tasks. Following steps were made
Modifying work structure by making teams
Involving staff at initial stage
Head of hospital cut down staff i.e.potenial use of staff to full extent.
Standardizing work-it means documenting in same way and making same forms for
visitors(Hansan,2012)
By implementing the lean production system in hospital, organization culture is changed and
team (doctors, nurses worked is promoted to satisfy end customers i.e. patients. Satisfaction is
only possible if entire supply chain in integrated into coherent way.

Pork sector:
Another example of practical implementation of lean production is pork sector ,that has adopted
demand management techniques. This implementation is example of greater collaboration of
supply chain collaboration to gain competitiveness in market. Members of this sector directed
their future strategies on innovation and collaboration to gain desired outcomes. Pork system has
cultural capability to apply lean system Castro, Gimenez ,& Simon(2010).
5-Challenges faced while implementing lean SCM:
A study conducted by Womack et al. (1990) Cited by by Agus& Hajinoor(2012) Despite the
benefits of lean production system there are many implementation challenges faced by
organizations. These are
Lean production changes the way people works but it does changes their minds to adapt
this new processes. So workers especially Blue collars find their jobs more challenging
for them as lean processes are implemented. Workers may find their job more stressful at
that time than even before.
A study conducted by Alabama Technology Network( 1998) cited by Agus&
Hajinoor(2012) said that It is takes time to distinguish value added activities from non
value added activities i.e. elimination of wastge.Wastage include overproduction, defects
in product, waiting for transportation, underutilized people etc.
Cultural difference
Lack of skilled work force
Lack of interest in implementing Lean SCM by supplier
Lack of commitment from top management
9
A company can cope up with these challenges by arranging the training session for workers,
making their minds that new processes are beneficial for all stakeholders. By streamlining all
processes from manufacturing to distribution non value added activities can be avoided. So lean
SCM is customer oriented.
6-Best practices that supports Lean SCM process:
According to Shah and Ward, 2003, 2007; Bhasin and Burcher, 2006; Pettersen, 2009; Agus and
Hajinoor, 2012 as cited by(Jabbour,Junior,& Jabbour, 2014) main practices that support Lean
SCM especially lean manufacturing are
Continuous flow
For reducing in production size it is important to make better control over production by
continuous flow of processes that reduces wastage.
JIT
By using kanban cards, it is easier to plan and control production flow to the extent that
production is done only when needed. It is produced only in required quantity
Reduction in setup time
By using SMED techniques machine setup time is reduced and a combination between
production quantity and variety is made.
Total production maintenance
By doing minor daily repairs or keeping machinery up to date can help avoiding
unnecessary stops during production. This reduces wastage and saves time.
Employee involvement
The main pillar of lean manufacturing and SCM is autonomation. This concept involves
employees in proposing suggestion for better performance and in this way in tough or
10
hard time employees provides support in achieving objective of minimizing wastage and
delivering high quality.
Continuous improvement
According to Naslund, 2008; Arnheiter and Maleyeff, 2005 cited by ( Jabbour,Junior,&
Jabbour, 2014) by using quality management techniques like total quality management
and PDCA (plan do check act) it is possible to find causes that are barrier in cyclic flow
and it is also possible to find their solutions. Companies are using an integrated
approached between lean manufacturing and six sigma to gain required performance. Six
sigma is tool for process improvement by defining, measuring, analyzing and controlling
the production process.
Supplier development
According to Liker (2005) as cited by (Jabbour,Junior,& Jabbour, 2014) supplier
development is a main principle of lean manufacturing that is supporting and challenging
the partner i.e. supplier in a way that it improves its own processes. It can be achieved by
collaborative efforts from supplier and manufacturer.
Logistic management
Logistic management is main component of Lean SCM practices; timely delivery of
product is an important for firm. For this purpose logistic network should be designed in
best way and should be greater collaboration with logistic services provider. Logistic
network should have flexibility of providing services according to demand. Smooth flow
transportation eliminates the need of buffer stock at all (Kodali &Jasti, 2015).

Information technology management
EDI are used to communicate between different departments. There is centralized
database for documenting .ERPS are employed at customer based for effective
communication. Effective and transparent flow of information is base for lean
SCM.Computer based decision aiding systems are used by firms (Kodali &Jasti, 2015).
While in lean SCM there should be good collaborative network among all parties i.e. supplier,
distributors and customer so that desired goals can be achieved (Jabbour,Junior,&
Jabbour,2014).Toyota motors was first to implement the concept of lean manufacturing and
followed all above practices.
7-Concluding remarks
Implementing lean SCM practices leads towards minimization of wastage, improved
performance, greater productivity, lower cost and best quality. To gain desired results in lean
production is well structured, well developed and collaborative relationship between customer
and supplier’s .the success of lean production depends upon long lasting relationship with
partners in supply chain. Lean production implementation in health care is discussed in this
report.
