Disadvantage of Software package:

There are some disadvantages which need to be looked into.

They are: 

i)  A commercial software package will have a number of built-in assumptions about the users. For example, the educational level of the users, their expertise in handling software, etc. are of speculative nature and hence may not be correct. Software vendors may not fully be aware of the organisational philosophy of different  organisations to whom they sell the software. This situation poses difficulties and some time has to be spent to resolve this difficulty in a counter productive manner before the software is installed and made operational: 

ii)  Some compromise will have to be made on the part of the purchasing organisation regarding its requirements as the software package is not a tailor made one. In other words, the package may not meet each and every requirement of the organisation. 

iii)  Use of a package may curb the innovative capabilities of staff computer specialists 

iv) Procurement delays and operational delays are not avoidable. In conclusion, it may be stated that the advantages of using a ready-made commercial software package are many as compared to the disadvantages and that is the reason why many organisations prefer to use such packages rather than develop their own applications software.
