Description

How to use this guide
The guide is divided into 7 sections.
Section 4 looks at purchasing decisions for PDSs. Please note
the following about the structure of this section:
Responsibilities and actions
Each type of purchaser is offered an explanation of their responsibilities. This is for awareness. No action is needed.
Following the responsibilities is a set of actions. If the purchaser
follows these actions, step-by-step, then conforming to the
relevant directives will be straightforward.
Tickboxes
Alongside the actions are tickboxes. Purchasers can photocopy
the relevant pages and use them as a checklist with each item
being ticked off as it is achieved.
Cross-referencing
Because of the complexity of conforming to each directive, this
guide inevitably carries a lot of cross-references to other sections. In the margin you will come across:
Defined on page XX
You are advised to turn to the page number reference.
You will also notice other references within the text. These can
be referred to if the item is unclear but is not essential for achieving compliance.
