Sometimes, the only way to solve a problem is by breaking it down into smaller parts.

Drill Down is a simple technique for breaking complex problems down into progressively smaller parts.

To use the technique, start by writing the problem down on the left-hand side of a large sheet of paper. Next, write down the points that make up the next level of detail on the problem a little to the right of this. These may be factors contributing to the problem, information relating to it, or questions raised by it. This process of breaking the problem down into its component part is called 'drilling down'.

For each of these points, repeat the process. Keep on drilling down into points until you fully understand the factors contributing to the problem. If you cannot break them down using the knowledge you have, then carry out whatever research is necessary to understand the point.

Drilling into a question helps you to get a much deeper understanding of it. The process helps you to recognise and understand the factors that contribute to it. Drill Down prompts you to link in information that you had not initially associated with a problem. It also shows exactly where you need further information.

Key Points

'Drill Down' helps you to break a large and complex problem down into its component parts, so that you can develop plans to deal with these parts. It also shows you which points you need to research in more detail.

    Hi Thomas_A_Hentrich

    Thanks for adding your ideas - both Fishbone and 5Why's are great techniques.
    Would you like to share more ideas with our readers about MECE?

    Some techniquest that can be referenced from this page, are Fishbone method, the 5 Why principle.

    Also, it should be mentioned that it is important to make each item on each level MECE (Mutually Exclusive Collectively Exhaustive).
