Explaining the Evolution of Supply Chain Management Essay

Over the past 40 old ages, the traditional buying and logistics maps have evolved into a wider strategic attack to stuffs and distribution direction known as SCM. This chapter will reexamine the SCM development over the past decennaries and the factors that have influenced this development.

After Second World War there was a high demand to increase production, the most portion of the universe was enduring from hungriness. The universe entered in the Productivism epoch, most makers ‘ gave precedence to mass production to minimise unit production cost as the primary operations scheme. This was the first phase of the creative activity of economic systems of graduated table. However, these old ages 1950s and 1960s the construct of supply concatenation direction was unknown. During these old ages new merchandise development was slow and counted merely in house ‘s ain engineering and capacity. Inventory cushioned constriction operations in order to keep a balanced line low, ensuing in immense investing in work in procedure ( WIP ) stock list ( Tan, 2001 ) . Logisticss cost were high every bit good. At a national degree in the USA and UK, they accounted severally for 15 % and 16 % of gross national merchandise ( Ballou 2007 ) . Furthermore, issues concern with buying was neglected by directors at that clip, since buying was considered as a service to production ( Famer, 1997 ) . As mentioned above increasing production was the chief aim of this period, small accent was on concerted and strategic purchaser provider partnership. Harmonizing to Tan ( 2001 ) , Sharing engineering and expertness with clients or providers was considered excessively hazardous and unacceptable.

Tan 2001 argues that, in the 1970s, directors become cognizant of the immense WIP on fabrication cost, new merchandise development, quality, and bringing clip. One of the factors of this increased consciousness was the debut of Manufacturing Resource Planning ( MRP ) . The focal point in this period changed ; it is non merely increase production through distributing the fixed cost to a bigger end product ( economic systems of graduated table ) , instead, to increase public presentation. The debut of IT ( MRP ) in be aftering the resources of the house cogent evidence this.

During the 1980s and 1990s, houses deal with increased demands for ‘better, faster, cheaper logistical service. As a consequence, many makers outsourced logistics activities and their focal point transferred to core competences ( Daugherty, 2011 ) . Harmonizing to Daugherty ( 2011 ) , the outside specializer presented an economically feasible agencies of accomplishing productiveness and efficiency. Therefore, many industries went more for a relationship ‘ oriented attack with their provider and client. They understood the benefits of concerted relationship with the other houses in the different concatenation degrees ( Stank at Al, 1999 ) . Stank at Al ( 1999 ) , show in their paper some of the advantages and benefits that this concerted relationship had: synergism addition through shared expertness and resources, better planning and support, exchange of information, and joint job resolution. Another ground that influenced the partnership between provider ‘ purchaser was the increased planetary competition ( Tan, 2001 ) .

In the 1990s was the debut of Enterprise Resource Planning ( ERP ) , this gave a encouragement to the development of the SCM and purchaser – provider relationship. Movahedi at Al ( 2009 ) argues, while the old IT resource be aftering systems ( e.g. EDI – Electronic Data Interchange ) used by industries were concern chiefly with inter – organisational integrating, ERP systems were chiefly concern with intra – organisational integrating. The development continues in the twenty-first century with the development of more sophisticated IT systems ( internet – base solution systems ) which are concerned for both inter-organizational integrating and intra-organizational integrating. Furthermore, the relationship purchaser ‘ provider in this period have gone one-step frontward, from normal partnership to long-run relationship and strategic confederations. Manufacturers and retail merchants now normally exploit supplier strengths and engineering in support of new merchandise development, distribution channels, cost decrease etc ( Morgan and Monczka, 1995 ) . For illustration retail merchants like Tesco use supplier strengths and engineering to do ain label merchandises which contribute to Tesco overall image.

The latest tendency of development in the supply concatenation direction is the motion towards systems of provider dealingss over national boundaries and into other continents ( Movahedi at Al, 2009 ) . Global Supply Chain Management ( GSCM ) is the latest construct introduced to the literature of SCM. Now twenty-four hours ‘s houses are much bigger than they used to be. They have achieved economic systems of graduated table and with the constitution of trade liberalization policies they are internationalizing their concerns to happen the lowest beginnings of inputs and turning markets to sell their merchandises. The construct of SCM is non plenty for being efficient and competitory in the new environment that is why new construct and direction schemes ( i.e. GSCM ) are emerging.

An Integrated supply concatenation gives considerable competitory advantage to the single histrions take parting in the concatenation. Now yearss in the developed economic systems there is a switch from house ‘ house competition to concatenation ‘ concatenation competition ( Koh at Al, 2007 ) . This last sentence describes best how the supply concatenation direction has evolved over the past decennary, by doing the different histrions in a concatenation to run as one large entity.

1.3 Evolution phases of supply concatenation direction

By looking at the above development history, we can place some turning points in the construct and doctrine of SCM. Some writers have segmented the development of supply concatenation direction into phases ( Movahedi at Al, 2009 ; Ballou 2007 ) . Movahedi at Al, ( 2009 ) segmented SCM development into three phases:

‘ Creation epoch ‘ During the 1980s

‘ Integration epoch ‘ During 1990s and continued in the 21st

‘ Globalisation epoch ‘ Now yearss

Creation epoch, starts ( 1980s ) when the purchaser ‘ provider understand the benefits that a concerted relationship offers. In this period we encounter for the first clip the term supply concatenation direction.

Integration epoch starts ( 1990s ) when the IT system EDI is replaced by ERP. ERP focal point non merely in pull offing the resources of the single house but besides the resources of the integrated supply concatenation.

Globalisation epoch, starts with the creative activity of the trade liberalization policies and the constitution of establishment such as World Trade Organization ( WTO ) and other international establishments that deal with global/regional trade policies.

Harmonizing to Ballou ( 2007 ) SCM is non new, it is a development of the buying and distribution map. The integrating of these two maps has generated what we call SCM. Figure 1 shows the development of SCM as described by Ballow ( 2007 ) . He has segmented the development of SCM into three phases.

‘ Activity atomization ‘ 1950s and 1960s

‘ Activity integrating ‘ 1960s to 2000

‘ Supply concatenation direction ‘ 2000+

As we can see from the figure, in the first phase the activities ( from buying row stuffs to complete merchandise in the shelf of a retail merchant ) are fragmented, there is no integrating between them. As a consequence the cost of finished merchandises ( transit cost, stock list cost etc ) are high. In the 2nd phase, there is some integrating between the activities but still non to the full integrated. The SCM 2000+ is the last phase where all the activities are to the full incorporate taking to be decrease, shortening of the new merchandise development procedure, better flow of information, improved hard currency flow, faster order fulfillment, improved shelf handiness and last but non least increased client satisfaction. From the SCM literature it comes out that client satisfaction is one of the cardinal impulsive factors of supply concatenation development.
