Siebel has created systems applications and business software as part of Siebel development. These applications and software comprised of areas that function differently but accordingly to meet the same end result. One significant area which can not be overlooked is the Scripting. Though it is never advocated to write script in Siebel, the computer language known as Escript is what needs to be done.
However, there is also a drawback in using scripting and that is the difficulty that can be achieved when making manageability and up gradation of Siebel applications. Though Escripting is hard to execute it can be also a benefit in becoming a successful Siebel Developer in Scripting and Configuration.
So, being knowledgeable in difficult wouldn’t do you any harm at all, instead it can provide you with so much opportunities to explore.
