Software or System Development Life Cycle

1. evaluation

   • is carried out in terms of the requirements elaborated in the first phase of the software development process
   • accuracy
   • speed
   • quality of output
   • capacity
   • security
   • reliability
   • functionality
   • flexibility

2. analysis

   • collect information
   • identifying inputs, outputs and process
   • identifying the problems
   • identifying the requirements

3. documentation

   • illustration that accompanies computer software or is embedded in teh source code
   • technical
   • requirements

   • direct
   • parallel
   • phased
   • pilot
   • a systematically structured approach to effectively integrate a software based service or component into the workflow of an organizational structure

5. development and testing

   • unit testing
   • integration testing
   • functional testing
   • system testing
   • accepting testing
   • non-functional testing

6. design

   • data capture forms
     • allows to input information
   • screen layouts
     • how things are positioned on screen
   • validation routines
     • reduce the amount of invalid data
   • verification
     • verify the data that enters
