to modiy, or it may require huge bus
ess process changes to implement.
‘+ The company will not have control
over software improvements and new
versions. (Usually it may only
recommend.)

integrate with czisting systems.
* Vendors may drop a product or go out
of business
۳۳2
Advantages of the "Buy” Option
+ Many diferent types of off-the-sbell
software are available.
+ Much time ean be saved by buying
rather than building,
+ The company can know what itis getting
before It invests in the software,

Purchased software may avoid the need
to hire personnel specifically dedicated
toaproject.
+ The vendor updates the software
frequently.
+ The price is usually much lower fora
