O que fazer se encontrar um problema complexo na Engenharia Automotiva?

Most of the people don't try to get the root cause they try to solve the problem in the hurry of solving the problem that is the main reason behind the issue reoccurring. We should follow DAMIC approach 1) Define-the problem 2) Measure- collect data 3) Analyze-Analysis by identify root cause 4) Improve -Develop and implement solution to address root causes and improve the process 5) Control -Establish control to sustain the improvement

Based on my past experience in this field, I can say that we should approach the problem step by step: - defining the problem - gather all the needed information - analyze the situation - brainstorm solutions - evaluate options - selecting an option - and finally implement and test the solution

As automotive engineering is broad area which includes many engineering disciplines most of the problems are complex. There are many system and sub-system needs to work in harmony to complete necessary function, also all those systems are dynamic systems make things more complex. However no need to worry, collect as musch as information you can, not only from the excat system also systems interface with that systems includding sub-systems. Check lessons learned files if someone already faced similar (or close) situation and they solve it. Gather as much as info regarding system and problem itself.

Now you have to sort the information you collected to creat logical story about root cause. You can use any of the root cause analysis method you would like to make things more organized. Do not forget to check FMEAs and DFMEAs of the system and sub-systems directly/indirectly related, that will help a lot. If that does not help, congratulations find new error mode :)

After identify possible root causes (there could be many) commnuicate with system responsibles. Involve them to find out "optimum" solution.

Brainstorming is a creative method for identifying potential solutions but we must plan it for Quick fix (ICA)and permanent fix(PCA) solutions. Brainstorming is a creative technique used in problem-solving to generate a large number of ideas or potential solutions to a problem. Here's how it typically works: 1) Generate ideas: 2) Encourage creativity: 3) Record all ideas: 4) Evaluate and refine: 5) Select the best ideas:

After brain storming probabaly you reach out some possible solutions. Now it is time to check if those solutions works. You can do testing on virtual environment or real life conditions. Choose optimum method, real life test most of the case better however not always optimum method. Check your timing-budget and scope and identify possible verification method.

You already tested and decided which solution is optimum, now it is time to implement that. Depends of the problem and solution, you can choose temperory or permanent solutions that is also valid for implementation. You can begin to implement on small pilot batch or directly mass production, you should decide that during that phase.

Now you have to control that solution created is good? It really solves the problem? Does it needs to be improved or fine tune needed? If updates needed on solution do it. If you satisfied back to documentation; first of all lessons learned file update it, then FMEA or DFMEA (depends of problem) needs to be updated. And never forget to celebrate that with the team who become part of that solution.

1) While solving problem pls use proper problem solving methodology, it could be TRIZ, 6-Sigma or sth else, that keeps you be organised and easy to track. 2) Update documents (FMEA, DFMEA, Lessons learned file etc). 3) Celebrate all stakeholders to being part of solutions, that makes them embrace the solution also increase the willingness to support further problems. Build team, never forget you are stronger with them!
