Banking Diploma: What is the meaning of Production?

What is the meaning of Production? 

         Production is the conversion of input into output. The factors of production and all other things which the producer buys to carry out production are called input.  The goods and services produced are known as output.  Thus production is the activity that creates or adds utility and value. 

In the words of Fraser
 "If consuming means extracting utility from matter, producing means creating utility into matter". 

According to Edwood Buffa
“Production is a process by which goods and services are created"
