Dear Friend, Transition Characteristics of the software : a) Interoperability : Interoperability is the ability of software to exchange information with other applications and make use of information transparently. b) Reusability : If we are able to use the software code with some modifications for different purpose then we call software to be reusable. c)Portability : The ability of software to perform same functions across all environments and platforms, demonstrate its portability.

a) Maintainability : Maintenance of the software should be easy for any kind of user. b) Flexibility : Changes in the software should be easy to make. c) Extensibility : It should be easy to increase the functions performed by it. d) Scalability : It should be very easy to upgrade it for more work(or for more number of users). e) Testability : Testing the software should be easy.

What are the Revision Characteristics of software ? These engineering based factors of the relate to 'interior quality' of the software like efficiency, documentation and structure. These factors should be in-build in any good software. Various Revision Characteristics of software are :- a) Maintainability : Maintenance of the software should be easy for any kind of user. b) Flexibility : Changes in the software should be easy to make. c) Extensibility : It should be easy to increase the functions performed by it. d) Scalability : It should be very easy to upgrade it for more work(or for more number of users). e) Testability : Testing the software should be easy. f) Modularity : Any software is said to made of units and modules which are independent of each other. These modules are then integrated to make the final software. If the software is divided into separate independent parts that can be modified, tested separately, it has high modularity.
