, 1.0 INTRODUCTION



In manufacturing, the root cause analysis is often used to prevent failures by analysing the main
factors that lead to the issues. The methodology of this analysis can be summarized as
identifying the failures, observing and investigating the reasons behind the failures and plotting
the solutions or further actions that can be taken to solve the problems.

Root cause analysis is vital to be performed properly to avoid company loss, waste of money
due to damaging, unwanted accidents and simply to improve the overall quality of the products.

There are few ways that can be used for performing the root cause analysis which includes
Fault Tree Analysis (FTA) and Failure Mode Effect Analysis (FMEA). The main difference
between these two techniques are by their own respective terms. FTA analyses the failures that
may happen by listing the possible factors that lead to the failures. FMEA on the other hand,
analyses the factors and list down the possible failures that may develop from the factors. They
are basically possessing the same factors and failures analysis but in the opposite order
accordingly. Figure 1.1 and Figure 1.2 shows the examples of FTA and FMEA, respectively.
