Found an ideal way to describe my job

It's mostly divided into 2 main parts:

1. Reduce process/cycle time and increase productivity
> This I am quite hopeless at cause my boss already worked on that for the last 10 years. I still cannot find significant areas to start digging.

2. Investigate defects and root causes
> This I came up with a very close fit analogy. It's really similar to Dr. House. you have a weird case, so you start doing different tests and coming up with different hypothesis to it. This is one of my favourite part of the jobs.
