The best method for planning proactive concurrency control methods and lock granularities is by using a cost-benefit analysis. This type of analysis looks at the tradeoffs between the costs associated with implementing the measure and its expected benefits, such as reduced deadlocks, increased throughput, etc. The goal is to find an optimal balance between the two that maximizes efficiency while minimizing costs. Additionally, this method allows for easy comparison of different solutions so that the most efficient one can be chosen.
