This chapter presents a methodical strategic technology engineering planning (STEP) approach, to effectively cope with the design complexity in service-oriented architecture and manage the strategic planning of solution development of information systems. This holistic model comprises four modules: Want-Is-Target (WIT) model, Transition and Alignment Grid (TAG), Comprehensive Architecting Process (CAP), and Joint Analysis & Roadmapping (JAR). The characteristics and features of the constituent elements in the STEP model are articulated in great detail. The WIT model defines three stages of architecture states – current, target, and end state. TAG specifies two dimensions for architecture planning, namely current-to-future state transformation and IT-to-Business alignment. CAP presents an overarching method for step-by-step engineering and design in system architecture and portfolio optimization. JAR comprises the best-of-breed strategic analysis techniques, accompanied by a hybrid method with strategy-driven and initiative-driven planning streams. Applying the framework in planning and future trends are also discussed in the context. This overarching framework provides a comprehensive multi-disciplinary approach to conducting strategic and tactical technology planning for both near-term needs and long-term goals.
Chapter Preview


Most of the previous architecture planning methods reveal the architectural aspects of a software application to some extent at a fairly high level or from a restricted perspective. A comprehensive approach to architecting the end-to-end information system solutions has become a necessity, calling for a systematic disciplined mechanism. To meet this growing need, a highly structured method is designed in this article to present a comprehensive and holistic view of the core architectural elements, components, knowledge, platforms, planning, and their interrelationships. Design procedures are established accordingly in this methodical approach to facilitate the creation, organization, and management of the architectural assets and solutions at different levels in a large organization.
