You might have a skill to repair cars or motorbikes. You might be good at fixing household appliances. You might be a good doctor. You might even be a good instructor. These are all your hard skills.
On the other side of the human coin, people will simultaneously count on your attitude while you are repairing a car. People will be counting on your on-time skill to finish an appliance repair job. Patients might be watching how you behave with them besides diagnosing and prescribing for them. Your pupils will be observing how caring you are while helping them to learn. These are your soft skills.
Standardization means a set of accepted specification that must be met to ensure quality. All employees must report at 9 a.m. in the morning, this is a standardized practice. All floors must be cleaned using vacuum cleaner on or before 8:30 a.m., this is a standardized requirement. However, it is difficult to standardize soft skills. It would be difficult to expect that doctors will smile and behave well with patients these days. It would be difficult to expect that the car mechanic would not produce fake reports and make some money. It is difficult to expect that the household mechanic would keep his commitment to finish a job on time. Since soft skills vary across people, this is difficult to standardize through a uniform set of code of conduct.
However, if you understand the “value” to customers created by these soft skills, you would love to practice and standardize these soft skills inside you. It is difficult, but not impossible. After all, smart people are good at achieving difficult things. Are we smart enough to standardize our soft skills?
