   1) Porter's Five Forces model is a useful tool for analyzing a company's strategies and gauging how competitive its industry is. Steve will understand the five forces in the model after I use the Shock Gaming Club as an example.
   

Competitive rivalry is a factor in how firms influence the production of other firms in the same area. The work of the gaming club Shock faces great competition from other gaming clubs due to the low price in these gaming clubs. But Shock wins this competition due to the high quality of their computers and service compared to other gaming clubs.
The trading power of the buyers of the Shock Club is the 2nd factor that informs about the influence of buyers on the business. People who come to the club can at any time demand a reduction in the price of computers, but the Shock club will justify their prices by saying that they are responsible for the quality of their computers as well as for their components.
The bargaining power of suppliers has little impact on Shock Club as gaming computer components come from overseas, especially in the US and for this reason, Shock can expand its supply chain from other countries to avoid the problem of high prices from US suppliers.
The threat of substitutes is a factor in how other gaming clubs can affect the club shock due to the low price and availability of gaming computer components. But the Shock club uses a development strategy that after a certain amount of time spent in the club you will receive a discount, and the second strategy is to provide better and more powerful computers than other gaming clubs.
Threat from new entrants because you never know if they will succeed or not. After all, such small gaming clubs can become popular and create strong competition, but the Shock Club has always tried to bring people to its club through high-quality gaming computers and their components.

   Operating in more than one of Porter's generic strategy areas would be challenging because if we strive to get an edge across all generic strategies, we risk becoming caught in the middle and failing even in a single strategy. Therefore, it is possible to choose only one of Porter's generic strategies to follow.

   Customer relationship management is a strategy how to manage all aspects of a customer’s relationships with an organization and how to increase the customer’s loyalty. For example, the Korzinka market made a discount card by which you can get 1% of the total amount that you spend in one month on market.
   

Enterprise resource planning is an IT system that includes all functions and departments of the entire organization so that employees can find a solution to the problem by viewing all the information in this system. For example, Amazon uses the “System Analysis and Program Development” which is ESR.

Supply chain management is managing information flows between and among operations in a supply chain to increase profitability and effectiveness overall. It consists of 5 activities: plan, source, make, deliver, and return.
