The purpose of the study is as follows. Along with the concept and range of the building planning task that has been discussed in the relevant literature and previous studies, we seek to reconfirm the motive and purpose behind the policy and set this as the standard of current status analysis to diagnose whether the policy is operating in alignment with the original objectives. We seek to deduce implications by interpreting actual cases that have performed building planning tasks based on the details and range of the planning, progress, utilization, etc. We want to identify structural supplementation or potential improvements in the performance of the policy, which may be necessary to advance the procedure to have practical significance.
