4M & 1E
I personally consider 4M & 1E as the "friendly basic compass" to structurally guide program managers. They are the main topic to be considered before a program manager can work on the details of matters in a structural manner.
A program manager can group each matter into these 5 categories, before working on the details. This helps the program manager to plan better, and utilize his/her limited resources more efficiently & effectively.
4M:
a. Man: All human resources related matter such as direct labor & indirect labor, hiring & firing, training, wages & benefits, knowledge & experiences, etc should roll under this category.
b. Machine: Anything related to equipments, testers, jigs, fixtures, calibrations, specifications of the machine, templates, pallets, tables & chairs, tools, etc.
c. Method: Any methods, instructions, specifications, guide, tolerance, etc.
d. Material: This applies to both direct & indirect materials.
Direct materials are the list of materials that is listed in the BoM (Bill of Material). They can be easily counted.
Indirect materials are materials that are not listed in the BoM (Bill of Material). Alternatively, they can be items that are difficult to count. For example the materials that are in liquid, semi-solid and powdery form.
1E
e. Environment: This applies to work station, temperature, ESD (Electro-Static Sensitive Device), moisture sensitive devices, air conditioned, humidity, vibration, air pressure, clean room environment, dust free requirement, etc. This is a rather small portion, but anything that is related to environment will fall under this category.
If you would like to know more on a basic 4M + 1E checklist, please write to me. I hope the templates that I have can minimize your efforts to re-invent the wheel.

Its really good , i'm requesting for checklist as u mentioned!
hi,
Just a Question for comments
Is a Change in Country of Origin considered a 4M change?
Thanks,
KP
Hi Kenneth,
Thanks for your question.
Yes. It is considered in 4M.
I would categorize the Change in COO (country of origin) as Materials. The COO relates to where the materials are being manufactured.
However, there is a catch in the COO, especially for parts that are being assembled before importing to a country. Certain countries does not actually take the COO as where the part is being manufactured, but more like where the raw parts are from.
For a quick & simple example: A ball point pen. The B.O.M. (Bill of Material) for the ball point pen would be plastic casing, the pen cover, the plastic tube that holds the ink, the ink, the pen tip, the label on the pen, etc). Where you get these B.O.M. determines your COO. Strict countries will strip your products down and check one by one. And if you are unlucky, your products will be held at the import customs due to incorrect declaration of COO.
Therefore, always revert to logistics partners before you ship a new product to a new country.
Hope this helps.
Thanks.
Best regards,
Ronald
