The Role of a North Star Vision during Phase A of Enterprise System Design

North Star Vision (NSV) is an essential strategic architecture of the enterprise systems, which stipulates the general direction of the technological project goals correlation with organizational targets and mission. The significance of NSV in directing enterprises that are moving to microservice-based systems form monolithic is highlighted in this paper. With NSV, cross-team synergy is enhanced as fragmented decisions, isolated developments and misaligned priorities are avoided, thus architectural consistency is achieved. The paper highlights the significance of TOGAF Phase A - Architecture Vision to institutionalize NSV, involve stakeholder in the process, and strengthen the fit between business goals and architectural deliverables. NSV is analyzed as an enabler of operational excellence, risk mitigation and innovation facilitation with the combination of short-term deliverables and long-term strategic objectives. In addition, NSV considers the tradeoff between flexibility and stability of architecture, a decisive parameter in the industries which experience fast technological development and competition. Applications in Amazon, Tesla and Netflix have shown how NSV can help in strategic alignment, idea generation and competitive advantage in real life. These cases indicate how NSV helps to control transitional and transformational change and incorporate sustainability and use technology through such methods as AI, IoT, and cloud computing. Therefore the conclusion of the paper is that a well defined NSV is not only risk reducing but brings about a visionary culture of governance and allows businesses to travel along the roads of uncertainty and updating.
