How to scope purchases | SSOA Part I/IV

Using e-Tools or making savings on its Purchases shall always start by a Strategic Sourcing Opportunity Assessment (SSOA) so to identify right priorities at start and spend rigth effort on right Sourcing Groups. Here is a basic 4-step-methodology that might help you to get started.

In this post, I will just explain the first step.

Howto Define the Scope of purchases to include in your Strategic Sourcing program

  • stage 1) Outline your company business structure
  • stage 2) Understand the importance of purchased goods and services to end-product costs and revenues
  • stage 3) Understand the importance of purchased goods in each BU
  • stage 4) Identify purchases by category (profile Sourcing Groups)
    • Below is a basic example on how to split the Sourcing Groups in 4 categories:
      • Category 1: Standard – in general low-value indirect spending and non critical services
      • Category 2: Leverage – in general high spending commodities as regular direct materials,
      • Category 3: Strategic – in general high spending administrative, Operating and Technical Services
      • Category 4: Bottleneck – in general one-shot buying as capital expenditure, investments

    Here (TBD) is a template that might be helpful to identify more precisely in which category lie your Sourcing Groups.

  • stage 5) Define Sourcing Groups using a 3 level family tree (at least)
    • Example of Levels: Sourcing family / Category / Sourcing group / Country or BU
    • Gather purchased items from the same category that can be provided from the same set of suppliers and with a similar approach,
    • Tipically you should have 50 to 60 Sourcing Families,
    • Creating SGs facilitates the sourcing strategy definition and the prioritisation,
    • Here is an .xls example of a Strategic Sourcing tree
  • stage 6) Identify and select the initial scope for the strategic sourcing program.
    • Selecting the first 3-10 Sourcing Families to work on.

By going through those 6 stages, you’ll have a good idea of your (the) company purchases and of their importance on the company bottom line, enabling you to select the first Sourcing families to put your efforts on.
