However, if we utilise the 5 Why mentality in our daily job scope, for example in Sales, Sourcing, it can be beneficial too.

I quote an example when I did a recent sourcing enquiry, upfront this is a simple plastic part to be machined, rectangular in shape with many slots profile. I got my usual partner to assist with the quote.

I was caught by surprise when I was told that no quotes to be given, thus I ask Why?

And I was told it is because there are too many profiles, usual method is too expensive, does not make economic sense to quote.

Why not other methods? There is but the plastic surface may have burnt marks.

Why not other methods without burnt marks? There is but they do not have the correct holding mechanism for this material which is another issue.

Why not the usual clamping? This material is too thin, have to use suction instead of clamping else will crack easily.

Why not we work with other partners who have the suction method? We can, but this thin material still prone to crack, suction will only reduce the risk of crack but not eliminate.

Thus you can see that, by asking the 5 Whys, we can then make an informed decision, in this case, do we quote? How do we quote? What are the precautions to be taken during production and during deliveries? What is the yield loss we should factor in?

So always ask Why till you are satisfied. It will help you in your next course of actions and decision making.
