, PART 1: INTRODUCTION
1. SCM & SCOR-model
1.1. Logistics <> SCM
Def. Logistics
The process of strategically managing the procurement, movement and storage of material
parts and finished inventory through the organization and its marketing channels so that
current and future profitability are maximized through cost-efficient fulfilment of orders.
Def. SCM
The management of upstream and downstream relationships with suppliers and customers
in order to deliver superior customer value at less costs to the supply chain as a whole.
1.1.1. The mission of logistics management
Logistics is a planning concept that seeks to create a framework (=kader) through which the
needs of the marketplace can be translated into a manufacturing strategy and plan, which in
turn links into a strategy and plan for procurement.
1.1.2. SC & competitive performance
A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer’s
request (bv. Fabrikanten, leveranciers, transporteurs, warenhuizen, retailers, klanten …)
2. Achieving an integrated supply chain
1) Every business function is completely
isolated from the other.
2) Adjacent (=aangrenzende) functions feel
the need to start a moderate integration.
3) Requires an end-to-end planning
framework in the entire organization.
4) The internal supply chain is linked to both
suppliers and customers à SCOR
8
, 3. The SCOR-model
SCOR = Supply Chain Operations Reference = the different supply chain processes, a
framework for relationships between these processes and a set of metrics to measure
process performance.
The 4 pillars of SCOR:
1) Process modelling & re-engineering
2) Performance measurements
3) Best practices
4) Skills
3.1. Process modelling & re-engineering
1) Plan = balance of demand and supply with a series of actions
2) Source = procurement (=buying)
3) Make = producing
4) Deliver = order, distribution & transportation management
5) Return = handling of returned products from supplier or customer
6) Enable = management of the supply chain (bv. Contracten, data, faciliteiten …)
This is an aggregate model = we’re not looking at individual products, but at the bigger
picture (not product itself, but the product line)
