The "drill down" method of problem solving is a technique that involves breaking down a complex problem into smaller, more manageable parts in order to identify the root cause and find a workable/better/optimal solution. It's a process of progressively examining more specific details within a problem to understand its various underlying components.<ref> | The "drill down" method of problem solving is a technique that involves breaking down a complex problem into smaller, more manageable parts in order to identify the root cause and find a workable/better/optimal solution.
