1	Introduction
This report presents the project planning and management aspects for the development of the shared bike software system commissioned by the local government. The purpose of this report is to detail the Project Scope Management and Project Schedule Management plans, ensuring that the project is completed successfully within the stipulated time frame and meets all specified requirements.
The local government has launched an initiative to address urban challenges such as increasing traffic congestion and deteriorating air quality. To promote a healthier and more sustainable lifestyle, they have introduced a shared bike program. Our company has been contracted to develop the software system integral to the operation of this program. This software will facilitate bike rentals and returns, manage the bike fleet, provide a user-friendly mobile application, integrate pricing and payment systems, and support operations and customer service.
We need to conduct this project to deliver a robust and efficient software platform that meets the government's requirements, contributing to the overall success of the shared bike program and, consequently, to the improvement of urban living conditions.

4.4	Earned Value Management (EVM) Analysis at End of Month 4
At the end of the fourth month, we conducted an Earned Value Management analysis to assess the project’s performance.
Assumed Values at End of Month 4:
•	Planned Value (PV): $1,272,000 (from the Cost Baseline)
•	Actual Cost (AC): $1,320,000 (actual expenditure incurred)
•	Earned Value (EV): $ 1,200,000 (value of work actually completed)
4.4.1 EVM Calculations
•	Cost Variance (CV):
CV = EV - AC
CV = $1,200,000 - $1,320,000
CV = -$120,000
•	Negative CV indicates the project is over budget.
•	Schedule Variance (SV):
SV = EV - PV
SV = $1,200,000 - $1,272,000
SV = -$72,000
•	Negative SV indicates the project is behind schedule.
•	Cost Performance Index (CPI):
CPI = EV / AC
CPI = $1,200,000 / $1,320,000
CPI ≈ 0.9091
•	CPI less than 1 indicates poor cost efficiency.
•	Schedule Performance Index (SPI):
SPI = EV / PV
SPI = $1,200,000 / $1,272,000
SPI ≈ 0.9434
•	SPI less than 1 indicates the project is progressing slower than planned.
•	Estimate at Completion (EAC):
EAC = BAC / CPI
EAC = $2,527,200 / 0.9091
EAC ≈ $2,780,000
•	EAC projects the total cost at completion based on current performance.
•	Estimated Time to Complete (ETC):
ETC = Original Duration / SPI
ETC = 8 months / 0.9434
ETC ≈ 8.48 months
•	ETC estimates the total project duration based on current schedule performance.
•	Variance Analysis
•	Cost Variance (CV): The project is over budget by $120,000, indicating that more money has been spent than the value of the work completed.
•	Schedule Variance (SV): The project is behind schedule by $72,000 worth of work, meaning less work has been completed than planned up to this point.
•	Cost Performance Index (CPI): At 0.9091, the project is not utilizing its budget efficiently.
•	Schedule Performance Index (SPI): At 0.9434, the project is progressing slower than planned.
4.5	EVM Graph
Figure 4.5: EVM Graph at End of Month 4
 
Note: The EVM graph plots the cumulative values of PV, EV, and AC over the project duration.
4.6	Project Performance and Forecasting Description
At the end of the fourth month, the project is experiencing both schedule delays and cost overruns. The Schedule Variance (SV) of -$72,000 and Schedule Performance Index (SPI) of 0.9434 indicate that the project is behind schedule, with less work completed than planned. The delay could result from complexities encountered during the design phase or underestimation of task durations.
The Cost Variance (CV) of -$120,000 and Cost Performance Index (CPI) of 0.9091 reveal that the project is over budget, spending more than the value of the work completed. Possible reasons include:
o	Extended Work Hours: Team members may have worked overtime to address challenges, increasing labor costs.
o	Unexpected Expenses: Additional costs, such as higher equipment prices or extra resources, may not have been anticipated.
The Estimate at Completion (EAC) projects the total project cost to be approximately $2,780,000, exceeding the original budget (including contingency) by $252,800. The project is also projected to extend to approximately 8.5 months, nearly half a month beyond the planned duration.
To address these issues, we need to:
•	Analyze the Causes: Investigate the reasons for schedule delays and cost overruns, such as scope changes, resource inefficiencies, or technical challenges.
•	Implement Corrective Actions: Reallocate resources, optimize processes, and implement cost-saving measures to improve CPI and SPI.
•	Update the Schedule and Budget: Adjust the project plan to reflect realistic timelines and costs, ensuring that stakeholders are informed of any changes.
By taking proactive steps, we aim to bring the project back on track, minimize the cost overrun, and meet the project’s objectives within the adjusted budget and schedule.
