Identify and explain the two relevant Human Resource Management concepts in detail in reference to the above scenario

Jennifer and Pierre graduated from university as business majors in June $2023$ and got the idea for starting a business because of a project they worked on together in their entrepreneurship class during their last semester. They named their business as LearnInMotion. The basic idea of the business is to design a website offering a vast array of web$-$based or textbook$-$based continuing education$-$type business courses for working people who wanted to take a course from the comfort of their own homes.

Jennifer and Pierre, turned to the task of hiring new employees. They were just about to place their ads when Pierre asked a question that brought them to a stop: "What kind of people do we want to hire?" It seemed they hadn't really considered this. They knew the answer in general terms, of course. For example, they knew they needed at least two salespeople, a programmer, a web designer, and several content management people to transform the incoming material into content they could post on their site. But it was obvious that job titles alone really didn't provide enough guidance. For example, if they couldn't specify the exact duties of these positions, how could they decide whether they needed experienced employees? How could they decide exactly what sorts of experiences and skills they had to look for in their candidates if they didn't know exactly what these candidates would have to do$?$
