The Information Services Procurement Library (ISPL) is a best practice library for the management of Information Technology related acquisition processes (derived from Euromethod). It helps both the customer and supplier organization to achieve the desired quality using the corresponded amount of time and money by providing methods and best practices for risk management, contract management, and planning. ISPL focuses on the relationship between the customer and supplier organization: It helps constructing the request for proposal, it helps constructing the contract and delivery plan according to the project situation and risks, and it helps monitoring the delivery phase.

It even provides the customer organisation with a table of contents. A very important part of the ISPL request for proposal is the elaboration on the supplier evaluation approach.

The use of a strategy that really fits the situation ISPL provides the user with a really extensive risk management process. Based on best practices, it helps the management to design a delivery strategy that really fits the situation of both the customer and the
