Features of system theory..

  Features of system theory

1) Goal-direct:

            A system is goal direct.it exists to achieve some target.

2) Sub system:

            The part of the system are subsystem.

           All the subsystem are related each other.

           They interact with each other.

3) Open or Close

            A system can open or close.

            Close system has no environment.

            Open system interact with the environment,

            Management is an open system. It responds to environmental changes.

4) Synergy:

            System thinks means that the whole is greater than the sum of its part.

            2+2=5

            It leads to synergy.

5) Boundary:

            Every system has a boundary that separates it form the environment.

            open system has flexible boundary.

6) Flow:

   A system has flow of information.

   They enter as inputs from environment.   

  They undergo transformation processes within the system.

       They go back to environment as outputs.

7) Feedback:

  It is getting information about actual performance.

  It is  the key to system control.

8) Entropy:

         It is the process of system decline.
     When organization fail to make corrections based on environmental feedback.

 ADVANTAGES OF THE SYSTEMS THEORY

1.   It focuses on the environment and how changes can impact the organization.
2.   Broadens the theoretical aspects for viewing the behavior of organizations.
3.  It is designed to deal with complex tasks.
4.  Takes an integrative total view of organization.
5.  It is useful for studying complex organization.
6.   Feedback facilitates changes in the system

  DISADVANTAGES OF THE SYSTEMS THEORY

1.  The systems theory doesn’t focus on specific task functions.
2.  Doesn’t provide for detailed focus.
3. The theory changes in environment directly affect the structure and function of the organization.
4.   Doesn’t directly explore the impact of interpersonal relationships and loyalty on productively.
5. The systems theory is complex for practical application.
6.   In small organization, it is not relevant.
7.  The theory is too abstract

Inheritance

Form of inheritance

A class can inherit properties from one or more classes and from one or more levels.

On the basis of this concept, there are five forms of inheritance. 

1.    Single inheritance
2.    Multiple inheritance
3.    Hierarchical inheritance
4.    Multilevel inheritance
5.    Hybrid inheritance
   
   
   
   2)      Multiple inheritance
    In this inheritance, a class is derived from more than one base class. The example and figure below show this inheritance.
   
    Example:-
   #include <iostream>
   #include<conio.h>
   using namespace std;
   class Teacher
       {
           int tid;
           char subject[20];
           public:
           void getTeacher()
           {
               cout<<"Enter Teacher id and subject"<<endl;
               cin>>tid>>subject;
           }
           void displayTeacher()
           {
               cout<<"Teacher ID::"<<tid<<endl;
               cout<<"Subject::"<<subject<<endl;
           }
       };
   class staff
   {
       int sid;
       char level[10];
   public:
       void getStaff()
       {
           cout<<"Enter staff ID and level"<<endl;
           cin>>sid>>level;
   
   
       }
       void displaystaff()
       {
           cout<<"Staff ID:"<<sid<<endl;
           cout<<"Level::"<<level<<endl;
       }
   };
   
   
   class coordinator: public Teacher, public staff
   {
       char program[10];
   public:
       void getdata()
       {
           getTeacher();
           getStaff();
           cout<<"Enter Program"<<endl;
           cin>>program;
       }
       void displaydata()
       {
           displayTeacher();
           displaystaff();
           cout<<"Program::"<<program;
       }
   };
   
   
   int main()
   {
       coordinator c;
       c.getdata();
       cout<<"----------------coordinator Details-----------------"<<endl;
       cout<<"***************************************************"<<endl;
       c.displaydata();
       getch();
