Question

Which SDLC model is the best suited for “ Door unlock using RFID card technology “ project ? And why? With describe phases of the model

Answer 1

Best suited model for Door Unlocking system using RFID is waterfall SDLC model. Because in this model gradual execution followed and process is strictly documented and predefined, which is very important for any software model if we design any device using software.

In waterfall SDLC model, proces go one by one, easy for small project and easy to prioritize tasks, easy to determine keypoints in development cycle.

Waterfall SDLC Model:

1) Requirement Gathering and Analysis: In this stage requirement of project and other documents is gathered for development.

2) System Design: After gathering all requirements of project design of project is done in this stage, in this stage block diagram of system and after that PCB based design is done.

3) Inplementation: In this process design engineer implement project by using software and after that on PCB and mount all necessary components on PCBs .

4) Testing: After implementing project on PCBs testing is done, in this stage testing of all module is done and every stage is tested.

5) Deployment of System: After testing everything, system is ready for deployment, in this process system is deployed as per the requirement of customer and all necessary checking is done.

6) Maintenance: After deployment if there is any problem in operation then maintenance is done. Generally maintenance part comes after many years, but if there is faulty components used then it may occur early.
