Intro to Project Management: Introduction to Project Management - What is a Project Definition, Characteristics Temporary Unique Progressive Elaboration

What This Is

A project is a temporary endeavor with a specific goal, scope, and timeline. It's unique in that it's a one-time effort to deliver a product, service, or result. Project managers use progressive elaboration, a process of iterative planning and refinement, to ensure the project stays on track. For example, imagine building a new hospital wing. The project involves designing, constructing, and equipping the space, all within a set timeframe and budget.

Key Terms & Formulas

• Project: A temporary endeavor with a specific goal, scope, and timeline.
• Temporary: The project has a defined start and end date.
• Unique: The project is a one-time effort to deliver a product, service, or result.
• Progressive Elaboration: Iterative planning and refinement to ensure the project stays on track.
• Scope Statement: A document that outlines the project's objectives, deliverables, and boundaries.
• Triple Constraint: Scope, Time, Cost – changes to one affect the others.
• EV = % complete × BAC (Earned Value = percent complete times Budget at Completion).
• BAC = AC + EAC (Budget at Completion = Actual Cost + Estimated Cost).
• CPI = EV / AC (Cost Performance Index = Earned Value / Actual Cost).
• SPI = EV / BAC (Schedule Performance Index = Earned Value / Budget at Completion).
• Earned Value (EV): The value of work completed, calculated as a percentage of the budget.
• Actual Cost (AC): The total cost incurred to date.
• Estimated Cost (EAC): The total cost expected to complete the project.

Step-by-Step / Process Flow

1. Define the project scope: Identify the project's objectives, deliverables, and boundaries.
2. Develop a project schedule: Create a timeline with milestones and deadlines.
3. Estimate costs: Determine the budget required to complete the project.
4. Monitor and control: Track progress, identify deviations, and take corrective action.
5. Iterate and refine: Use progressive elaboration to refine the project plan and adjust as needed.

Common Mistakes

• Mistake: Failing to define the project scope clearly. Correction: Develop a scope statement that outlines the project's objectives, deliverables, and boundaries.
• Mistake: Not considering the triple constraint. Correction: Recognize that changes to scope, time, or cost will impact the other two.
• Mistake: Not tracking earned value. Correction: Calculate earned value regularly to assess project progress and performance.

Exam Tips

• Watch for trick questions: Be cautious of questions that ask you to choose between similar-sounding options.
• Understand the difference between earned value and actual cost: Earned value represents the value of work completed, while actual cost represents the total cost incurred.
• Be aware of the impact of scope changes: Changes to scope can affect the project's timeline, budget, and resources.

Quick Practice Questions

1. If the CPI is 0.8, is the project under or over budget? Answer: Under budget. Explanation: A CPI of 0.8 indicates that the project is earning value at a rate 20% higher than expected, suggesting it's under budget.
2. If the EV is $100,000 and the BAC is $200,000, what is the SPI? Answer: 0.5. Explanation: The SPI is calculated as EV / BAC, which equals $100,000 / $200,000 = 0.5.
3. If the AC is $150,000 and the EAC is $200,000, what is the CPI? Answer: 0.75. Explanation: The CPI is calculated as EV / AC, but since we don't have the EV, we can use the formula CPI = (BAC - AC) / (BAC - EAC). Plugging in the values, we get CPI = ($200,000 - $150,000) / ($200,000 - $200,000) = $50,000 / $0 = undefined. However, we can use the formula CPI = (BAC - AC) / (BAC - EAC) to find the CPI. Since we don't have the EV, we can use the formula CPI = (BAC - AC) / (BAC - EAC) to find the CPI. Since we don't have the EV, we can use the formula CPI = (BAC - AC) / (BAC - EAC) to find the CPI.

Last-Minute Cram Sheet

• Project: A temporary endeavor with a specific goal, scope, and timeline.

• Unique: The project is a one-time effort to deliver a product, service, or result.
• Progressive Elaboration: Iterative planning and refinement to ensure the project stays on track.
• Scope Statement: A document that outlines the project's objectives, deliverables, and boundaries.
• Triple Constraint: Scope, Time, Cost – changes to one affect the others.
• EV = % complete × BAC (Earned Value = percent complete times Budget at Completion).
• BAC = AC + EAC (Budget at Completion = Actual Cost + Estimated Cost).
• CPI = EV / AC (Cost Performance Index = Earned Value / Actual Cost).
• SPI = EV / BAC (Schedule Performance Index = Earned Value / Budget at Completion).
• Earned Value (EV): The value of work completed, calculated as a percentage of the budget.
• Actual Cost (AC): The total cost incurred to date.
• Estimated Cost (EAC): The total cost expected to complete the project.
• Progressive elaboration is not a one-time activity, but an ongoing process.
• Earned value is not the same as actual cost; it represents the value of work completed.
• The triple constraint is not a fixed relationship; changes to one aspect can impact the others.
