this project may overflow if it is not properly monitored. Figure 3 shows the prototype model phases
such as requirements, quick design, build a prototype, user evaluation, refining prototype, implement
and maintenance.

Table 2 shows the comparative study of SDLC models according to the requirement specification
including understanding the requirement, cost, resource control, expertise required, user involvement
and integrity and security of the model and phases. The models are compared according to the phases
and the activities involved in the approach.

Model Waterfall Model Prototype Model
Requirement Specification Beginning Frequently changed
Understanding Requirements Well Understood Not well understood
Cost Low High
Resource Yes No
Expertise Required High Medium
User Involvement At the beginning High
Integrity &Security Vital Weak

The model used for this development is the waterfall model as it is a straight model hence easy to
utilize. The requirements and analysis phase acts as the first phase which gathered and analyzed
needed information. Some statements indicate what a system needs to do to provide a capability. The
system and Software Design process act as the second phase in the system development process. The
developer team first analyzes the problem, choose the right System Development Life Cycle (SDLC)
method to use, draw Use Case Diagram, Flowchart, system sketch and Entity Relationship Diagram
(ERD) for the Examination Management System.
