Go online and search for project life cycle models. Identify at least two that are different from the PMI model, and compare and contrast the phases. Be sure to cite your sources.

Software project decision point. You need to determine an interest rate to use—select an interest rate and explain why you think this number should be used. Use it in your calculations in item 1.2. Given the information below on options 1 and 2, carry out three forms of analysis: breakeven, ROI, and NPV. Make a recommendation on which way to proceed, based on the TCO for each option.

Option 1: Purchase the FunSoft package: Cost $200,000 for software and $85,000 for hardware in year one; with $50,000 to customize it and a $40,000 annual licensing fee for the life of the contract. There will be an annual saving of $61,000 due to the layoff of a clerk.

Option 2: Purchase the SoftComm package, which will operate on the vendor’s hardware: Cost $250,000 for a five-year license, payable half up front and half during the first year of implementation. The maintenance contract, at $75,000 a year, includes all currently identified modifications to the software for the first three years. The clerk’s hours will be cut by half, for a saving of $25,000 a year.

In both cases, sales are expected to increase from the current $1 million a year, by 10% per year each year (over each year’s previous year’s sales) after full implementation. Assume a five-year life for the software.

The project lifecycle models serve as structured frameworks that guide the development, execution, and completion of projects. Among the numerous models available, the Waterfall Model and the Iterative Model stand out due to their distinct approaches toward managing project phases. By examining their phases and comparing their methodologies, organizations can better align project strategies with their specific needs.

The Waterfall Model is one of the earliest, linear approaches to project management. It emphasizes sequential progression through predefined phases: requirements analysis, system design, implementation, integration, testing, deployment, and maintenance. Each phase must be completed before moving to the next, with minimal scope for revisiting previous stages. This model fosters a disciplined, systematic process suited to projects with clear, unchanging requirements, such as in construction or manufacturing industries (Royce, 1970). Its structured approach ensures thorough documentation and easy manageability but often lacks flexibility, making it less suitable for projects with evolving requirements.

In contrast, the Iterative Model emphasizes cycles of development, where a project is broken into smaller segments called iterations or increments. Each iteration encompasses planning, design, development, testing, and evaluation, allowing teams to revisit and refine previous phases based on feedback. This incremental approach supports flexibility and adaptability, making it ideal for software development projects where requirements can evolve during the lifecycle (Larman & Basili, 2003). The iterative process enhances stakeholder engagement, reduces risks by early delivery of components, and accommodates changes effectively. However, it requires meticulous planning and effective management to prevent scope creep.

When comparing these two models, the Waterfall model's linearity provides clarity and straightforward management but at the expense of flexibility. Changes are costly to implement once a phase is completed. Conversely, the Iterative model's cyclical approach allows for refinement and adjustments, accommodating changes more readily. However, it can lead to scope creep if not carefully controlled. Both models have strengths and limitations; organizations should select the appropriate model based on project complexity, clarity of requirements, and stakeholder involvement (Boehm, 1988).

Analysis of Software Purchase Options

For the decision between purchasing FunSoft or SoftComm, financial analysis is essential. An interest rate must be selected to evaluate the projects' worth over time. For this analysis, I will choose a 7% discount rate, reflecting typical corporate required rates of return, balancing risk and opportunity cost (Brealey, Myers, & Allen, 2014). This rate is reasonable given current market conditions and the company's risk profile.

Break-even Analysis

The breakeven point identifies when the cumulative cost savings offset initial investments. For FunSoft, the initial investment includes software, hardware, and customization costs, totaling $200,000 + $85,000 + $50,000 = $335,000. Annual savings of $61,000 reduce the payback period to approximately 5.49 years ($335,000 / $61,000), exceeding the five-year life span, indicating it may not fully recoup the investment within the software's useful life.

For SoftComm, the initial purchase cost is $250,000, with $125,000 payable upfront and $125,000 in the next year. Annual maintenance costs are $75,000, with savings from halved clerk hours at $25,000 annually. The breakeven point, considering only direct savings, occurs after approximately 11.54 years ($250,000 / $25,000), which is beyond the project's five-year horizon, suggesting limited financial return based solely on clerk savings.

Return on Investment (ROI) Analysis

ROI provides a percentage measure of profitability. Under the assumptions, FunSoft's total net savings over 5 years are (5 $61,000) - initial costs (excluding licensing as ongoing expenses), leading to an ROI of approximately 47% ((($305,000 - $335,000) / $335,000) 100). For SoftComm, the direct savings from clerk hours ($25,000 * 5 years = $125,000) slightly offset the purchase and maintenance costs, resulting in a negative ROI unless additional benefits are considered.

Net Present Value (NPV) Calculation

NPV discounts future costs and savings to present value, incorporating the selected interest rate. Calculating NPV for FunSoft with a 7% rate indicates the investment may have a negative net value over five years, primarily because the payback period exceeds the project's lifespan. Conversely, SoftComm's NPV suggests minimal or negative return given the limited savings within five years, unless considering increased sales from higher capacity or additional intangible benefits.

Recommendation

Based on the financial analyses, FunSoft appears to be less favorable due to its longer payback period relative to its life cycle and marginal ROI. SoftComm's higher initial investment and maintenance costs outweigh the direct savings over five years. However, potential sales increases and strategic advantages might offset these findings. Therefore, I recommend further exploration of non-financial benefits like enhanced scalability or customer satisfaction. If the primary goal is quick financial recoverability, neither option strongly outperforms the other within the five-year window. A comprehensive evaluation integrating projected sales growth, strategic benefits, and risk considerations should guide the final decision.

Conclusion

Choosing an appropriate project lifecycle model depends heavily on project characteristics. The Waterfall model offers structure suited for projects with fixed requirements, while the Iterative model provides flexibility beneficial in dynamic environments like software development. Financial decision-making regarding software investment requires careful analysis using tools such as breakeven, ROI, and NPV, adjusted through a rational discount rate. Ultimately, balancing technical project management considerations with financial analysis can lead to optimal decision-making.
