reply to this in summary answer :

All institutions and organizations need management methods for work procedures and systematic planning to achieve goals, and there are factors affecting management style that are divided into internal stimuli such as employee skills, priorities and procedures of the organization's culture, and external influences such as competition, customer base, and economic factors.
The first answer: The reliable management method is an administrative method in which employees must follow the manager's orders. Questions cannot be discussed and asked, but rather do what the administration says in the same approach. When employees do not follow the orders, the manager punishes them. Despite this, employers and employees still prefer the methods. Reliable administrative over the participatory group management methods because reliable management is characterized by many positives, including first, if the manager is present, the team becomes more productive. Second, everyone knows exactly what their responsibility is and what they are expected to do, and clearly defined roles contribute greatly to the reduction of productivity errors. With regard to the participatory management method, both administrators and employees are part of the decision-making process, and employees do not prefer this method because the decision-making process will be slow compared to the reliable management method. Also, employees may sometimes not want to be part of the decision-making process, and therefore the manager will be annoyed. From the actions of employees and the increase in conflicts between employees as a result of conflicting views.
The second answer: The participatory group management method does not succeed in most administrative cases of institutions as a result of multiple factors, and among these factors is the lack of a high degree of mutual trust between employees on the one hand and management on the other. There are mistakes, and also the difference of opinions between employees and management contributes to the conflict of ideas and management, which makes the decision-making time slow, which negatively affects the institution. Also, the unwillingness of employees to participate in their opinions contributes to the disruption of decision-making, and there will be great pressures, and therefore it will be difficult to make a decision It satisfies all employees, and also the participatory method can cause an increase in the cost as a result of taking a longer time to make the decision, and in the event of failure to make the decision, they will waste more resources and money to fix the result of the wrong decision, and insufficient knowledge will cause many problems as a result of the lack of training and experience for the employees necessary for decision-making, so the participatory method is highly susceptible to failure.
