The System Development Life Cycle
Discuss about the Case Study Of The High Quality Institute.
The system development procedure is very important for any type of organization. The report henceforth is concerned with the case study of the high quality institute. The organization is looking to develop a system that would be helpful in their organization procedures. The organization is looking to incorporate two systems within the development which are the Undergraduate Learning System (ULS) and Postgraduate Learning System (PLS).
The detailed description of both the system which are to be developed in incorporation are provided in this report. The software developer staff at the IT department assigned the task of developing both learning systems from scratch.
The report consists of the information about the system development lifecycle of the software and also the work Breakdown structure of the development of the project, Additionally the ER Diagram associated with the development and the cost calculation is also provided in this report.
The system development life cycle is very important for any type of development of the software is very important. For the current project the waterfall model is selected and the processes that are involved in the model for the development of the system are; Analysis and feasibility phase, the planning and requirement phase, design phase, the testing phase, the deployment phase and the maintenance phase.
For the analysis phase the work should be strong about the deficiency that would be existing in the current structure for deciding the goals of the new approach. The feasibility study would also determine if the project goals and other aspects are viable for the organization and the society on a whole or not. In addition to this, the technical personnel of the organization would also perform the feasibility study on the project so that the technically the project works for the advancement of the organization. In addition to this, the overall project scope and the aims and objectives of the project are also defined in this phase of the development of the software. The economic, external factors and the human resources are also important which are to be processed during this phase and the schedule is also developed during this phase.
In the planning and the requirement phase the adaptations for the new system and the development of the completely new system is developed in this phase. The users’ requirement, hardware and software requirements and the overall capacities of the project are developed in the planning phase of the development.
Work Breakdown Structure (WBS)
In the designing phase the costs of the system and the requirements of the users are identified and are worked up on. The designing of the front end part and the database concepts such as the ER diagram and the data model are developed in this phase. After the planning phase the system development and the implementation of the system starts. The developers perform the coding and the designing of the system. The back coding and the integration of the system is done during the implementation phase of the project. Additionally, the physical configurations and the access control features are also performed in the implementation phase.
After the implementation phase the testing phase of the project is started. As the project that is being discussed in this report is a IT oriented project hence, the testing phase would involve the procedures of the usability testing, the responsive design testing and the UI testing. After conducting the testing, the users would be providing valuable insights for the further development of the project and this would help the developers to improve the final product to great extent.
After the implementation phase the project sign off stage would be processed by the developer and during the sign off phase the documentation about the project and system manual would be submitted to the owners. The project team would also be dissolved during this phase.
The work breakdown structure for the project that is to be completed within the budget is provided below:

Conclusion
For conclusion it can be said the project development would be done using the waterfall model and the budgeting and the schedule of the project is done according to the waterfall model. The schedule of the project indicates that the project can be completed in the 95 days and the payback period is calculated to be 2.3 years approximately. Hence, the report provides the entire details of the development of the software by the organization.
