  • Also known as Systems Development Life Cycle (SDLC), is a very formal process with the below mentioned stages:
    • System Analysis
    • System Design
    • Programming
    • Testing of system
    • Conversion/ Implementation
    • Production a...

Explanation of Solution

Information Systems Prototyping:

  • It is a radical approach than traditional systems but is only a working model that is developed in a test environment.
  • It a repetitive, iterative approach and a hit or miss approach.

Advantages:

  • When initial end user requirements are not clear, this method is the best approach.
  • It is suitable for end-user interfaces.
  • It can expedite the process while working with end users.

  • It is a quick and easy solution for generalised processes in an organisation.
  • For example, basic features of accounting, human resources, and so on.
  • A cost-effective approach to buy as a package rather than implementing a system from scratch...

Explanation of Solution

End-User Development:

  • It provides user the ability to develop systems that require no or very less formal assistance from information system technologies.
  • These days fourth generation language programs ensure for development of these packages.

Advantages:

  • A solution for end user completely fulfilling its needs and requirements.
  • They can be developed so it is easy to be applied in an existing workplace.
  • These tools can provide an opportunity to improve programmer’s productivity.

Disadvantages:

  • They are not suitable for heavy use or massive amounts of data...

Explanation of Solution

Advantages:

  • Company can save its resources as well as reduce costs by hiring external agencies rather than hiring additional manpower.
  • It can depend on specialists to provide high quality solutions rather than developing systems in its own premises.
  • Develop relationship and better experience...
