Q

System Development Life Cycle Six core processes are:

A
  1. Identify the problem or need and obtain approval
  2. Plan and monitor the project
  3. Discover and understand the details of the problem or need
  4. Design the system components that solve the problem
  5. Build, test, and integrate system components
  6. Complete system tests and then deploy the solution
