I am unable to imagine something "achievable", but not Worth doing. Probably, some examples would help.
It all depends on how you define "improvement," and the concept of optimization--making something as good as possible within known limitations. You might have a production process that results in predictable yields, and increasing the yield would require expense in excess of what the additional yield is worth. If you do something that increases yield but causes you to lose money, you haven't improved anything. An increased yield is achievable, but not worthwhile (or realistic).

Drs. Deming and Ackoff's writings were full of such examples of one entity thinking they were improving something, but to the detriment of the whole.

For example, the purchasing department at a hospital decided to start buying less expensive catheters that were also sharper than the ones previously used. Saved money, and you'd think have a better tool. But they didn't inform the doctors, and incidents of cuts and lacerations caused to both doctors and patients went up considerably. An overall loss for the hospital.

I think the question of Feasibility to achieve something interms of Cost, Quality, technology, etc etc is in-built, when we say something is "achievable". If not, everything is achievable. Correct me, if I am wrong.
Or in other words, 0 ppm for Customer rejection for Casting parts is not achievable or not realistic.

0 ppm for Customer Rejection is achievable. Depends upon how much you want to pay for 100% inspection, especially if you want to eliminate 'operator error' (aka 'inspector error') by using methods such as automated vision inspection systems.

0 ppm for a casting process is probably not achievable, but it depends upon volume. The lower the volume, the more 'personal' the process will be (example: A local jeweler who casts and produces a small number of rings to a customer's requirements (vs. outsourcing)). As the volume decreases, the probability of 0 ppm of the process increases.

The "R" in SMART is there because it completes a useful acronym. A better word would be "worthwhile," but that would make the acronym "SMAWT," which sounds like Elmer Fudd. Nonetheless, if you replace "realistic" with "worthwhile," the idea should be clear. A thing might be achievable but not worth doing.
I cannot agree more. Achievable means you have some way to get to that objective, and realistic means the thing you plan, when succeed, will do some help to you and your system.

There are things you can do, but does not help the system. On the other hands there are other super things that you need for the system, but way beyond your capability and budget.

Thus need to consider both while you set up your target.

Re: Achievable vs. Realistic - Differences and Definitions

How about the "A" of SMART stands for action-oriented, which means that goal should involve some action on your part.

That is, perhaps, why some authors prefer to call it 'relevant' rather than 'realistic'. Relevant denotes aligned to the Organisation's mission/vision etc.

Actually, it is. I have audited with 2 companies who maintained 0 external ppm in cast parts, month after month, with only a rare random exception. Technically not 0 ppm, if there was a random glitch, but averaging 0-1 ppm overall for several years).

Both were automotive suppliers. They felt it was achievable and realistic (necessary to maintain customer satisfaction and cheaper than having complaints). Perhaps we could argue, it would have been preferable to agree with the customer to allow a few defects to control costs, but automotive OE's don't seem to think that way. A lot depends on your customers and what you are able to negotiate with them.

PS: an interesting side note, I mentioned this to a machining company who insisted that 10% incoming casting defects was acceptable. They then talked with their suppliers and quickly reduced their incoming defects to less than 2%.
