All of business principles in most of department seems to be reasoned out of these Te-Si functions.
Extroverted thinking paired with introverted sensations will be best at applying those policies / principles into practices, since they tend to be a judger and an action oriented people.
There are many of business principles taught, but I may only explain one of them here.
Principles of Hiring
Let take one as the example like the principles of hiring management. It is usually applied in Human Resources Department within the same company or may be in Head Hunter as an independent business entity. They plan only to hire professional that they judge will be able to complete their required work for them, since they are liable to pay the employee that the money that they pay must be exchanged with something useful, worth for the company. They hold this principles. It is reasoned that the money they pay will be futile if they pay it for incompetent ones, who aren't capable of getting the job done but want to get paid. Salaries paid, but job get done and they claim ownership of it as theirs is their goal of practicing this principles, which will be beneficial for them. They plan to get a lot of job done by different professionals in different departments by practicing this principles.
Getting Their Man
Their campaign is that it is important to hire competent people e.g you may have heard "the right person in the right place" and look for them. You may have notice that some job portals on the web that advertise job vacancies is where they can source their candidates from. That is the way they practically search for the candidate they want to hire. The job portals may charge the company that put job vacancies on their web but they usually do not charge the job seekers. Nowadays their recruiting practice seems to get helped with job website online applications. They name the job position that is vacant,and write the job descriptions and pay the portals to advertise it and further source their candidates from it. They screen candidates applied for the position, and may invite them for further process: test, interviews, etc. They try to match their need to the candidates attributes and make decisions. Candidates accepted will be offered a job. if accepted they have got their professional. If not, they'll have to look for another.
Performance Monitoring
After getting them, They are going to monitor whether the they do get from the professional hired the work they want, as an exchange of the money the employer pay. They are going to assess whether the professionals they hire do /do not perform as they want, whether the assignment are /are not completed, target are/ aren't achieved.
They may assess strictly by fail and success, achieve or not, meet the target or not, and they do not only judges; they also follow it up by taking actions. whether or not they want to extend/not extend hiring contract decision. The judgement whether we will be , on behalf of employer, should or not extend the employee contract after it is expired. It will be decided objectively based on, for example, whether the employee have an acceptable performance of not. When they judged that the employee performance during her/his tenure under their contract period is acceptable, they will follow it up by offering an extension. But if not, they won't. They'll let the employee find another job in other company and they will be looking for another hire, still following the principles of hiring.
Series of Judgement Followed up by Actions Taken
You may have realized that the process is a series of judgements and taking actions. Like, making a decision to source the candidate by buying a membership of job portal falls under extroverted judgement and taking actions. The decision has to be made because They face a problem like they need a professional for a position, but they do not know how they get them. To solve it, Action has to be taken to contact the job portal, make an agreement and pay them in order the hiring officer are allowed to use the job portal as their sourcing device. If they do not take actions, they won't solve their problem. After their got their candidates interested in the job advertisement, they have to screen them and invite them for further process: series of test and interviews, which are also a series of judgement and taking actions. After testing and interviewing some candidates, they may offer a job for the most suitable. Next they are going to prepare for a working contract to be sent to the candidates accepted, which is also judging and taking actions. And so on.
ESTJ and ENFP is advised to Major In Business
The principles theoretically can be explained by any type, but to put it into practice in real business environment, will need energy of action oriented person. Who is naturally will be energetically sufficient in putting this into practice is Psyche with Te-Si. Te-Si tend to judge and follow up by taking action, hence only An ESTJ or ENFP will be energized at making sure that the principles will be practiced as it is theorized. Business Management will be best if studied by psyche with Te-Si like ESTJ (Te Primary paired with Si auxiliary) or ENFP (Te tertiary paired with Si). Therefore, they are highly recommended to major in business management and might further take higher degree like MBA. It will be easy for them to understand it and further apply it after graduation in their career.
