Gemba
The first “G” is called the Gemba.  “Go to the real place” The Gemba is the place where the event took place /at the source of the problem. It is critical that your team start by jointly going to the Gemba to start your investigation.
 
Genbutsu
The second “G” is known as Genbutsu. “Examine the Object/tool”. While at the Gemba, your team observe the equipment parts and materials that were involved in the equipment failure.  In most cases, the part may have been removed or replaced before the team has assembled.  Hence, your team must keep the failed part handy to perform analysis to see if you can find any evidences to see how the part failed.
Genjitsu
The third “G” is Genjitsu. “Check the real facts”, for this step, your team must gather all the available data about the process, equipment, and materials before and after the equipment failure.   This data will play a key role in link the facts behind the evidence that the team sees and understand what really happened.  
 
Genri
The fourth “G” represents Genri. “Vefiy the Principles” Having the principles of operation available while your team is gathering data about the equipment is key in being able to position the correct movement of the equipment.  This will help your team clearly see how the equipment is different from standard.
 
Gensoku
The fifth “G” is Gensoku. “Check the Process SOPs/Standard practices” There is a chance that the equipment didn’t just fail because it was poorly manufactured.  The team must also have knowledge of the operating procedures that administer the actions of the machine operator and verify that human intervention did not lead to the equipment failure.  You should reference your process SOPs, instruction manual during your investigation
