my Myers-Briggs personality : INTJ

Your personality type:  "The Architect"  (INTJ-A) Strength of individual traits: Introverted: 37%, Intuitive: 61%, Thinking: 12%, Judging: 6%, Assertive: 22%. Role:  Analyst Strategy:  Confident Individualism   INTJ PERSONALITY ("THE ARCHITECT") It's lonely at the top, and being one of the rarest and most strategically capable personality types, INTJs know this all too well. INTJs form just two percent of the population, and women of this personality type are especially rare, forming just 0.8% of the population – it is often a challenge for them to find like-minded individuals who are able to keep up with their relentless intellectualism and chess-like maneuvering. People with the INTJ personality type are imaginative yet decisive, ambitious yet private, amazingly curious, but they do not squander their energy. Nothing Can Stop the Right Attitude From Achieving Its Goal With a natural thirst for knowledge that shows itself early in life, INTJs are often given th...

SU 1 Chapter 1 <Introduction to OM> - define OM OM are activities that relate to the creation of goods and services through the transformation of inputs(resources that the firm employ) into outputs(finished goods/services performed). - describe process of value creation by transforming inputs into outputs This transformation process (from input to output) also brings about a creation of value. where the finished goods or service performed brings about a greater value to the customer. - differences between goods and services from OM perceptive GOODS good can be defined as a tangible product that is something that you can touch such as your mobile phone.  goods possess a unique set of characteristics, such that you can define goods easily and its specification is consistent throughout. example: mobile phone is capable of making calls and sending text messages. what are two very basic functions which one can easily defined. production of a goods takes place priority   consumption ...
