Achievable vs. Realistic

MBO - SMART
Gemma, UK
Achievable v realistic... Is achievable more relevant to the individual completing the tasks? Whilst realistic may tak into account external factors out of the control of the individual?

SMART: Achievable vs Realistic
Pam, USA
An easy way to see the difference between achievable and realistic is with weight loss. Is having a goal of losing twenty pounds in two weeks SMART? It is specific, measurable, achievable, but losing twenty pounds in two weeks is not realistic. Changing the time frame can make this achievable and realistic.

The A in SMART
Ian Moody, Trainer, United Kingdom
Whilst the most commonly accepted meaning of SMART leads the test to be Achievable this is far too 'close' to realistic. If we consider Drucker's views on the role of contemporary management as being
(a) objective setting
(b) work organisation
(c) motivation
(d) measuring performance and control
(e) developing people
Drucker emphasised communication as a prime management function evidenced in (a), (c) and (d).
We should surely think in terms of Agreeable, which also works well with good delegation practice and appraisal systems.
