Intro to Project Management: Project Procurement Management - Statement of Work, SOW Terms of Reference TOR

What This Is

A Statement of Work (SOW) and Terms of Reference (TOR) are essential documents in project management that outline the scope, objectives, and deliverables of a project. A SOW is a detailed document that describes the work to be performed, while a TOR is a concise document that outlines the project's objectives, scope, and deliverables. Both documents serve as a foundation for the project's scope statement and are used to ensure that all stakeholders are aligned and working towards the same goals. For example, when building a new bridge, the SOW would outline the construction process, materials, and timelines, while the TOR would specify the bridge's design requirements, safety features, and expected completion date.

Key Terms & Formulas

• Statement of Work (SOW): A detailed document that describes the work to be performed, including scope, objectives, and deliverables.
• Terms of Reference (TOR): A concise document that outlines the project's objectives, scope, and deliverables.
• Scope Statement: A document that outlines the project's scope, including the work to be performed, deliverables, and exclusions.
• Scope Creep: The uncontrolled expansion of a project's scope, which can lead to cost and schedule overruns.
• Scope Verification: The process of ensuring that the project's scope is complete, accurate, and meets the stakeholders' expectations.
• Scope Change Request (SCR): A formal request to modify the project's scope, which requires approval from stakeholders and the project manager.
• Earned Value (EV): A measure of progress that takes into account the work completed and the budget allocated to that work (EV = % complete × BAC).
• Budget at Completion (BAC): The total budget allocated to a project or activity.
• Cost Performance Index (CPI): A measure of cost efficiency that compares the actual cost to the budgeted cost (CPI = AC / EV).
• Schedule Performance Index (SPI): A measure of schedule efficiency that compares the actual schedule to the planned schedule (SPI = EV / PV).

Step-by-Step / Process Flow

1. Develop the SOW and TOR: Create a detailed SOW and a concise TOR that outline the project's scope, objectives, and deliverables.
2. Scope Verification: Verify that the project's scope is complete, accurate, and meets the stakeholders' expectations.
3. Scope Change Request (SCR): Establish a process for handling scope change requests, including approval from stakeholders and the project manager.
4. Monitor and Control Scope: Continuously monitor and control the project's scope to ensure that it remains aligned with the SOW and TOR.
5. Scope Closure: Formalize the completion of the project's scope by documenting the final deliverables and obtaining stakeholder acceptance.

Common Mistakes

• Mistake: Failing to develop a clear and concise SOW and TOR.
• Correction: Ensure that the SOW and TOR are well-defined, concise, and aligned with the project's objectives and deliverables.
• Mistake: Not verifying the project's scope.
• Correction: Regularly verify the project's scope to ensure that it remains aligned with the SOW and TOR.
• Mistake: Not establishing a process for handling scope change requests.
• Correction: Establish a clear process for handling scope change requests, including approval from stakeholders and the project manager.

Exam Tips

• Tip: Be able to distinguish between a SOW and a TOR.
• Tip: Understand the importance of scope verification and the process for handling scope change requests.
• Tip: Be able to calculate the Earned Value (EV) and Cost Performance Index (CPI).

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 actual cost is 80% of the budgeted cost.
2. What is the formula for Earned Value (EV)? Answer: EV = % complete × BAC. Explanation: Earned Value is calculated by multiplying the percentage of work completed by the Budget at Completion.
3. What is the purpose of a Scope Change Request (SCR)? Answer: To formally request a modification to the project's scope. Explanation: A SCR is used to request changes to the project's scope, which requires approval from stakeholders and the project manager.
