• Program Development Life Cycle (PDLC) phase:

  1. Problem definition
  2. Problem analysis
  3. Algorithm development
  4. Coding and documentation
  5. Testing and debugging
  6. Maintenance
• STEP 1 PDLC: PROBLEM DEFINITION

  DEFINITION: Defining the problems, the objectives and the resources such as personnel & costs
• Step 2: problem analysis involves analyzing the problem by determining and documenting the end-user's requirements, including their expectations for the system's performance.
• STEP 3 PDLC: ALGORITHM DEVELOPMENT DEFINITION: Defines the elements of a system and general system design • This phase defines the elements of a system, the components, the security levels, modules, architecture and the different interfaces and type of data that goes through the system
• STEP 4 PDLC: CODING & DOCUMENTATION DEFINITION: Actual construction process after having a complete and illustrated design for he requested system
• STEP 5 PDLC: TESTING & DEBUGGING DEFINITION: Obtain and analyse its outputs, behaviour and the way it functions to ensure that the actual outcomes are compared and equal to the predicted and desired outcomes
• Step 6 PDLC: MAINTENANCE DEFINITION: To make sure that the system won't become obsolete - providing latest update for certain components
• Step 1: problem definition After analysing this data, we will have three (3) choices - develop a new system, improve the current system or leave the system as it is
