Tactical Projects and Flyover in City

Just a thought, if Enterprise Architecture is analogous to City planning than Tactical project becomes analogous to flyover in City.

Flyover is constructed to reduce the bottleneck at one junction/crossing. Similarly Tactical project is executed to provide the short term solutions.

Flyover results into traffic jam on subsequent crossing after the flyover. Now we need to build another flyover to remove this bottleneck. Is it right approach? Or do we need long term planning to handle increasing traffic and a better public transport to take care of public. A better infrastructure and proper city blueprint to avoid all these traffic jams.

Same thing happens to Tactical project, which results into another tactical and another tactical. We need Enterprise Architecture to prepare Blueprint and vision of enterprise. This will help in reducing risk and cost of IT.
