Process Improvement to Fix Oil Leakage

Having found a problem that occurs is processed and identified. The next step is the improvement that might be done as follows:
A. Increase Hydro Test Press: to overcome the problem of insufficient hydro test pressure. With proper handling with problems that occur in production will be obtained is the result to be satisfactory.
2. Use black light Inspection To overcome the problem of black light unused and to increase oil leak problem.

With known clearly that the problem occurs, it will be proper handling steps. Thus the improvement measures will produce the expected reduction.
After the reduction process improvement will be generated as shown in the chart below:

Root Causes with Fishbone Diagram Analysis

Still associated with the case presented in the previous article, Process Performance(for example the case of reducing the leakage of oil), Fish Bone diagram will facilitate the search for problems that cause oil leakage. This is an analysis process to determine in detail the roots of the problems occurred.

The following image is a simple example to find the cause of the problem.



Causes of the search there are two root root causes can be identified that Black light inspection procedures are not appropriate. And insufficient hydrostatic test pressure has been running during the process.

Process Performance (for example the case of reducing the leakage of oil)

Graph increasing number of oil leaks in diesel fuel. In the following picture there is an increase in leakage every time, so we have to make observations and analysis to solve problems that occur.

Improvement story should be filed

There are several documents that must be considered by the leaders and members to ensure continuity of process improvement to come.

These documents should be stored in an orderly manner to ensure ease for other members to find and translate the improvements has been achieved. And further improvement will be easy to come by finding a gap that has not been touched before.
