This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Fault Tree Analysis Made Easy
If you are ITIL certified, you’ve heard of Fault Tree Analysis, or FTA.
But if you’re like most, you probably have no idea how to actually
perform or use FTA! Simply put, FTA is a method for discovering the root causes of
failures or potential failures. FTA then helps you understand how to
fix or prevent the failure. FTA is an analysis that starts with a top-level event, like a service
outage. You then work it downward to evaluate all the contributing
faults, and the causes of faults, that may ultimately lead (or have led)
to its occurrence. You use the fault tree diagram to identify
countermeasures to eliminate the causes of the failure.
FTA requires nothing more complex than paper, pencil, and an
understanding of the service at hand. You will need accurate
Configuration Information (CI) contextual information in order to get
the most value from FTA.
The following 6 simple steps, available here, can help you
resolve tough design issues or problems quickly and easily.
