Parallel implementation: uses both the legacy system and new system until all users verify that the new system functions correctly. Plunge implementation: discards the legacy system and immediately migrates all users to the new system. Pilot implementation: assigns a small group of people to use the new system until it is verified that it works correctly; then the remaining users migrate to the new system. Phased implementation: installs the new system in phases (for example, by department) until it is verified that it works correctly. The phases in the systems development life cycle: planning, analysis, design, The testing phase brings all the project pieces together into a special testing environment to eliminate errors and bugs and verify that the system meets all the business requirements defined in the analysis phase.
