TRANSCRIPT

The general principlesof value chainmanagement

Tom McGuffog and

Nick Wadsley

Introduction

Electronic commerce is set to revolutionise

most business and administrative processes.

However, speedy certain value chains are pre-

requisites for delivering both public and

private products and services competitively.

Simple, standard value chains minimise un-

certainty and delay and make the application

of electronic commerce much more cost

effective. The development of value chain

process analysis, supported by collaborative

event management over the Internet, the

structuring and synchronisation of master

data among organisations, and the sharing of

customer focused value chain data, power-

fully enhance the performance of value chains

and of electronic commerce. SIMPL-EDI

global data definitions, codes and messages

lead to simple, standard communications

across the Internet and also support enter-

prise to enterprise communications via EDI.

This leads to simple, standard internal IT

applications ± a virtuous cycle.

These developments are progressing well in

the UK as part of global initiatives in

conjunction with e-centreuk (EAN) and UN-

CEFACT.

Specialisation

In his Inquiry into the Nature and Causes of the

Wealth of Nations, Adam Smith (1776)

describes how the division of labour improves

productivity. `̀ The division of labour occa-

sions, in every art, a proportionable increase

in the productive powers of labour. The

separation of different trades and employ-

ments from one another, seems to have taken

place in consequence of this advantage. This

separation, too, is generally carried furthest in

those countries which enjoy the highest

degree of industry and improvement; what is

the work of one man is a rude state of society,

being generally that of several in an improved

one'' (Smith, 1776, p. 5).

The division of labour reduces costs, which

in turn stimulates demand. As the extent of

the market grows, so can specialisation be

taken further. As the degree of specialisation

increases, so it becomes economic to replace

human skills by machinery. As equipment

becomes more specialised, new departments

are set up to operate these. Indeed specialist

work is then often outsourced to another firm.

Abstract

Explores the principles of value chain management, as

they apply to both public and private products, and

explores the impact of e-commerce and collaborative

planning through the Internet on reducing costs and

uncertainty in supply chains. Drawing on experience from

global initiatives with e-centreuk, and recent applications

within Nestle UK, makes a plea for simplicity and

standardisation in electronic commerce, to support speedy

and certain value chain management across the globe.
