Project Management

Project: A temporary endeavor undertaken to create a unique product, service, or result. Triple Constraint: Scope, Time, and Cost (Quality at the center).

Concept: A hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and deliver required deliverables.

Concept: The longest sequence of dependent activities through a project network diagram which determines the shortest possible duration to complete the project. Float on the critical path is zero.

Distinction:

• CPM (Critical Path Method): Deterministic model with known, fixed activity durations (common in construction).
• PERT (Program Evaluation & Review Technique): Probabilistic model using 3 time estimates (Optimistic, Most Likely, Pessimistic) for uncertain research/development projects.

It represents the amount of time an activity can be delayed without delaying the project completion date.

Concept: A project monitoring methodology that integrates project scope, cost, and schedule metrics to assess project performance and progress against the baseline.

If $\text{CPI} > 1$, the project is performing under budget (efficient); if $\text{CPI} < 1$, the project is over budget.

Concept: A schedule compression technique in which extra resources are added to critical path activities to shorten overall project duration at the lowest additional cost.

Concept: The uncontrolled expansion of project scope without adjustments to time, cost, and resources, usually leading to project failure.

Concept: A formal evaluation conducted after project handover to assess whether intended business benefits were achieved and document lessons learned for future projects.

1. Initiating: Defining project charter, business case, and identifying stakeholders. 2. Planning: Establishing total scope, defining WBS, schedule network, budget, quality standards, and risk register. 3. Executing: Coordinating project teams, procuring equipment, and building deliverables. 4. Monitoring and Controlling: Tracking progress, managing scope changes, analyzing EVM variances, quality audits. 5. Closing: Formal deliverable acceptance, contract closeout, financial settlement, and archiving lessons learned.

Step 1: Expected Time ($t_e$):

Step 2: Standard Deviation ($\sigma$):

Step 3: Variance ($\sigma^2$):

EVM Metrics:

• Planned Value (PV): Authorized budget assigned to scheduled work.
• Earned Value (EV): Value of work actually performed expressed in terms of approved budget.
• Actual Cost (AC): Real cost incurred for work performed.
• Cost Variance (CV): $\text{CV} = \text{EV} - \text{AC}$ (Positive = under budget, Negative = over budget).
• Schedule Variance (SV): $\text{SV} = \text{EV} - \text{PV}$ (Positive = ahead of schedule, Negative = delayed).
• Schedule Performance Index (SPI): $\text{SPI} = \frac{\text{EV}}{\text{PV}}$.

Risk Management Steps:

1. Identification: Brainstorming, Delphi technique, checklist analysis.
2. Qualitative Risk Analysis: Prioritizing risks by Probability and Impact rating.
3. Quantitative Risk Analysis: Expected Monetary Value (EMV), Monte Carlo simulation.
4. Risk Response Strategies:
   • Negative Risks: Avoid, Mitigate, Transfer (insurance/subcontracting), Accept.
   • Positive Risks (Opportunities): Exploit, Share, Enhance, Accept.

Key Responsibilities:

• Leading cross-functional project teams and resolving interpersonal conflict.
• Managing stakeholder expectations and scope change requests.
• Ensuring project delivery on time, within budget, and meeting quality standards.
• Proactive risk identification and crisis management.
• Transparent status reporting to project steering committee.

Causes of Delays in Nepal:

• Land acquisition and right-of-way disputes.
• Inadequate detailed engineering design and frequent mid-stream design changes.
• Bureaucratic delays in environmental impact assessment (EIA) and tree-cutting approvals.
• Public procurement disputes and low-bidding by contractors leading to abandoned sites.
• Geographical landslides, terrain difficulties, and seasonal monsoon interruptions.

Step 1: Identify Network Paths:

1. Path 1: $1 \to 2 \to 4 \to 5$ (Activities A $\to$ C $\to$ E)
   • Duration = $4 + 5 + 7 = \textbf{16 days}$.
2. Path 2: $1 \to 3 \to 4 \to 5$ (Activities B $\to$ D $\to$ E)
   • Duration = $6 + 3 + 7 = \textbf{16 days}$.

Step 2: Critical Path & Project Duration: Both Path 1 and Path 2 have equal maximum duration of 16 days. Hence, both paths are Critical Paths:

• Critical Path 1: A – C – E (16 days)
• Critical Path 2: B – D – E (16 days)
• Total Project Duration: 16 Days.

Step 3: Earliest and Latest Times Table:

Conclusion: All activities have zero float; any delay in any activity will delay the entire project.

Step-by-Step Calculations:

1. Cost Variance (CV):

   $$\text{CV} = \text{EV} - \text{AC} = 420,000 - 480,000 = -\textbf{Rs. 60,000 (Over Budget)}$$
2. Schedule Variance (SV):

   Swipe to see the full formula↔

   $$\text{SV} = \text{EV} - \text{PV} = 420,000 - 500,000 = -\textbf{Rs. 80,000 (Behind Schedule)}$$
3. Cost Performance Index (CPI):

   Swipe to see the full formula↔

   $$\text{CPI} = \frac{\text{EV}}{\text{AC}} = \frac{420,000}{480,000} = \textbf{0.875}$$
   (For every rupee spent, only 87.5 paisa worth of work was completed).
4. Schedule Performance Index (SPI):

   Swipe to see the full formula↔

   $$\text{SPI} = \frac{\text{EV}}{\text{PV}} = \frac{420,000}{500,000} = \textbf{0.840}$$
   (Project is progressing at only 84% of scheduled rate).
5. Estimate at Completion (EAC):

   Swipe to see the full formula↔

   $$\text{EAC} = \frac{\text{BAC}}{\text{CPI}} = \frac{1,000,000}{0.875} = \textbf{Rs. 1,142,857}$$

Project Health Interpretation: The project is in critical condition: it is running behind schedule by Rs. 80,000 and over budget by Rs. 60,000. If current efficiency continues, total cost will overrun by Rs. 142,857 over the original Rs. 10 Lakh budget.

1. National Planning Commission (NPC) Role: Formulates national periodic plans, establishes project appraisal guidelines, and conducts central project monitoring and evaluation (M&E).

2. Status of National Pride Projects:

• High capital commitments with immense economic transformation potential (hydropower, highways, airports).
• Chronic delays: Time overruns of 5–10 years and cost escalations exceeding 100% due to geological surprises, poor contractor accountability, and political instability.

3. Required Institutional Reforms:

• Transition from lowest-bid (L1) tender awards to Quality and Cost Based Selection (QCBS).
• Fast-track land compensation dispute tribunals.
• Enforcement of strict liquidated damages on defaulting contractors.
• Depoliticization of Project Directors with fixed performance-based tenures.
