Answer: The three sources of software are:

  1. Information Technology Services Firms,
  2. Cloud Computing,
  3. Open-Source Software.
  1. Information Technology Services Firms:
  • When a company needs information system but does not have enough resources or expertise to develop system on its own and not suitable for off-the-shelf system, Information Technology Service Firms help to develop customized information system.
  • IT service firms helps in developing, hosting and running applications.
  • Firm consultants use many of the same processes, methods, tools and techniques that companies use to develop in-house systems.
  • The examples of such IT firms are IBM, HP, Accenture, Wipro, Infosys and more…

REASONS TO CHOOSE Information Technology service Firms:

  • Internal staff of company may have limited resources available with them while IT service staff can have many multiple resources available which increases Productivity as well as Flexibility.
  1. Cloud Computing:

  • Customers can use software through virtual private networks or Internet.
  • Most popular example of cloud computing is Google Apps and Microsoft.
  • Helps in maintaining hardware and software systems more effectively.
  • Data can be retrieve easily through just setting connections to Internet.

REASONS TO CHOOSE Cloud Computing:

  • Cost structure of cloud computing is more flexible than traditional methods.
  • Accessing speed of software can be increase.
  • Once storing data/information on cloud server, we can access data from anywhere and at any time.
  1. Open-Source Software:
  • The software in which source code is freely available is likely to be termed as OPEN-SOURCE software.

Custom Software Development: The software, which is design and develop for some specific purpose for user or company.

Off-the-shelf Software: They are the software, which can be purchase and are ready to use for public.

E.g. Microsoft Office.

  • Basically, it is a Build or Buy choice for organization (whether to build custom software or to purchase off-the shelf software). No doubt, Off-the-shelf software are initially good in saving time and money but later on they are quite difficult to manage and customize as they are bound with their rigid features while on other hand Custom Software Development requires high cost for the development but at the same time they are more flexible in compare to off-the-shelf software’s as Custom Software’s can be transform as per changing requirements of business or client.
  • Many times, it happens that we have to pay for the features, which are of no use to client or firm in Off-the-shelf software, so instead of paying money for unwanted features it is better to invest that amount in developing Custom Software.
  • Hence, Custom Software is long-term benefit while Off-The-Shelf is short-term benefit.
