CWA 14838-2:2003

Facilitating Smart Card Technology for Electronic Ticketing and Seamless Travel - Part 2: Development of Smart Card Based Interoperable Ticketing Systems CWA 14838-2:2003

Scope

The aim of CWA 14838-2:2003 is to provide guidelines on the elaboration of a business case for introducing an open smart card based e-ticketing scheme and procurement strategy.
The key principle that is urged throughout is to evaluate the costs and the risks involved in system migration in order to arrive at a robust business case. Security is a key issue that must be considered at the earliest stage, so that suitable measures can be embedded in the system design.
This part of the CWA aims to take the reader through the various stages of the business case analysis from the identification of business objectives and the development of a business strategy, through the development of a procurement strategy, guidelines on an operational framework that can achieve secure interoperability between schemes, the identification of appropriate types of fare products that can be generated within this framework and technical requirements, and finally a summary of security aspects.
Although the Clause dealing with security requirements comes last in the document, it is strongly recommended that security issues be considered at the earliest stage, so that suitable measures can be embedded in the system design. The Clause on security is thus intended to provide a summary of the security principles that should pervade the whole design process and certainly the costs of adequate system security need to be included in the elaboration of the business case.
In practice the elaboration of an appropriate business case will involve reiteration until a cost-effective design scheme for a secure, efficient new scheme has been achieved, or the activity is abandoned. Business process considerations are addressed in more detail in CWA 14838:3 and it is recommended that the guidelines provided in the latter part of the CWA be applied for the proposed scheme before the business case analysis commences.
