Comparison Of Modified Waterfall Model With Unified Process For Software Development

Task 1.   System Development Methodology
Provide a short description of each of the following system development methodologies, and then compare the two. The comparison should describe the advantages and disadvantages of one methodology versus the other.
Modified Waterfall Model
Unified Process
Note that this question is not specific for the Scenario.
What to include in your report for this task?
 1. Description of both methodologies
 2. Comparison of the methodologies
Task 2.   Work Breakdown Structure
For the Online Mercy Hospital Pharmacy system Project, assume you have chosen Modified Waterfall Model as a Methodology. 
Create a Work Breakdown Structure (WBS).
The WBS must be created as a table, either directly in your MS Word report, or using other software (e.g. Excel, Project) and then copied/imported into your report. If you use other software, then you do not need to submit the original file. The WBS must contain only the following columns:
Task ID 
Task description
Estimated duration/effort (in days)
Predecessor Task ID(s)
What to include in your report for this task?
1. The Work Breakdown Structure (a table).

Task 3.   Project Gantt Chart
For the Online Mercy Hospital Pharmacy system, create a Gantt chart of the project. You must include allocation of personnel. Also provide an explanation of the Gantt chart, including any assumptions that were made in preparing it.
What to include in your report for this task?
1.A screenshot or copy-and-paste of the full Gantt chart. You MUST also submit the original  MS Project file
2.Explanation of Gantt chart and any assumptions
Task 4. Economic Cost Feasibility/ Project Budgeting
Conduct a 5-year cost/benefit analysis by:
1.Create an Excel spreadsheet in common format.
2.Explain the breakeven period for the project, including what does breakeven period mean,what is the value for this project, and what that value means to the customer.
3.Explain the return on investment for the project, including when does return on investment mean, what is the value for this project, what that values means to the customer, and whether the project is worthwhile and should be continued or not.
What to include in your report for this task?
1.A screenshot or copy-and-paste of the cost/benefit analysis spreadsheet. You MUST also submit the original MS Excel file.
2.Answers about the breakeven period
3.Answers about the return on investment

Work Breakdown Structure (WBS) of the Project

Modified Waterfall Model: The system development methodology utilizes the same phases as in waterfall model with a simple addition of the overlapping function (Model 2015). The overlapping functions help in splitting the projects in subprojects for ensuring that each of the sub projects are completed successfully.

Unified Process: The unified process is implied as an iterative, incremental, and development process that can be used for software development in form of a process framework (Hui, Yan, Quanyu and Zhiwen 2015). The unified process is not a process, but it is a structural framework that can be specified for organizational projects.

Table 1: WBS of the Project

From the Gantt chart it is clear that the project is divided into the following subprojects initialization, planning, system designing, system development, testing, and closure phase. The initialization phase consists of analysis of the requirements, scope analysis, risk management plan, charter documentation, project initiation documentation, and review and signup. The planning phase consists of plan selection methodology, development of plan outline, review of the plan outline, and plan approval. The system designing phase consists of hospital infrastructure is analysed, system requirements are accumulated, design methodology is selected, design outline is made, design is reviewed, and design is approved. The system development phase consists of platform for integration is selected, integrated database is formed, data in stored in the database, equipments are installed, software are programmed, and system is completed. The testing phase consists of white box testing, black box testing, simulation testing, and prototyping. The closure phase consists of submission of documents, final documentation, review and signup, and project is closed.

The break even period (or point) is the time period for which the sum of the overall investment is equal to the sum of the benefits for given discounting rate (Rout, Sahoo, Thomas and Varghese 2017). The time is said to be breakeven point for the initial investment at the given rate of return. The breakeven point for the project is 2.57 years for 7%. The payback period is the breakeven point of the project for the customers.

ROI of return on investment is the rate by which the investment of the project is returned to the client (Frost, Sonfield, Zolna and Finer 2014). The yearly benefits are summed and lessened from the yearly expense. The remaining amount is divided from the initial investment and then percentage is calculated for developing the ROI. The ROI for this project is 30%. The NPV value of the project has been calculated to be positive and hence, the project should be proceeded with.
