Strategic systems planning

Advances in technology are creating a profusion of opportunities for increasing the value and cost-effectiveness of telecommunications, for example through the provision of new services for the customer and the use of more economical systems designs. But telecommunications is a complex and highly interactive process, and if the best use is to be made of the opportunities presented, a framework of definitions is required for the coordinated development of systems. Following extensive studies of the definitions required, the Post Office and its principal suppliers are developing a family of standard switching and associated systems, collectively known as System X. Based upon digital, software and micro-electronic technologies, System X is intended to increase the cost-effectiveness and evolutionary capabilities of the British network, with designs that are fully competitive on world markets. The definitions used for System X cover customer service and network interworking requirements, systems architecture, and a range of design standards and procedures. The arrangements enable vital interactions to take place between production and operational interests, and between the definition and design processes. System X is part of an overall systems strategy that is being progressively created. It links System X with other developments, in terms both of service performance and technical standards. In all its aspects, strategic systems planning is expected to lead to the creation, in cost-effective ways, of basic capabilities providing hitherto unattainable opportunities for extending telecommunications services, increasingly in a global context. The continuing reconciliation of global needs and local aspirations in telecommunications represents perhaps the greatest challenge to strategic systems planners worldwide.
