Activity: Add confidence ratings
1. To pass this practice quiz, you must receive at least 80%, or 4 out of 5 points, by completing the activity and answering corresponding quiz questions. You can learn more about the graded and practice items in the
In this activity, you will assess the time estimates in your project plan and add confidence ratings based on notes from a project team meeting.
Review the scenario below. Then complete the step-by-step instructions.
By now, Peta has added a number of tasks to the project plan and assigned them time estimates. Now Peta wants to get a sense of how confident the team is that those time estimates are accurate. This information will allow her to update the timeline for completion and be fully prepared to launch the project.
Step 1: Access your draft
Begin by opening the project plan draft you worked on in the last activity, Get accurate time estimates.
Step 2: Access supporting materials
The following supporting materials will help you complete this activity. Keep them open as you proceed to the next steps. Each link below will open a new Coursera tab.
Meeting: Project Update
For this activity, you may also want to access the following supporting materials from earlier activities:
Historical Project Plan
Email Exchange: Tablet Logistics
Meeting: Tablet Training
Meeting: Waterfront Location
Meeting: North Location
ablet Shipping Estimate
Meeting: Menu and Coupons
Meeting: Scheduling Software Installation
Note: To access additional supporting materials introduced in earlier activities, you can find them in the
Step 3: Review the supporting materials
Review the notes from the project team meeting. As you review, take notes on the feedback Peta asks for on certain tasks, keeping in mind you will be responsible for updating confidence ratings in the project plan. Make note of details related to best-case and worst-case scenarios, and how confident the team is with the task estimates discussed at the meeting.
If you identify any new tasks from this meeting that were not already included in your project plan, you can add them to the Task column under the Task Brainstorm tab of your project plan.
Step 4: Add three-point time estimates
Next, select at least four tasks and add three-point estimates for each task. Use the supporting materials provided in this and previous activities to determine an Optimistic time estimate, a Most Likely time estimate, and a Pessimistic time estimate for the task. Add these estimates to the corresponding columns under the Task Brainstorm tab in the project plan.
Step 5: Add confidence ratings
Next, add confidence ratings to at least four of your tasks in the Confidence Ratings (H/M/L) column under the Task Brainstorm tab.
Step 6: Add notes
Finally, add notes to at least four tasks. Notes can include any information on a task critical to time estimates or its completion. You can pull them from the project team meeting notes or any previous supporting materials.
What to Include in Your Response
Be sure to address the following criteria in your project plan:
Three-point time estimates for at least four tasks in the project plan
Confidence ratings for at least four tasks in the project plan
Notes for at least four tasks in the project plan

2. The meeting notes state that training will happen in two phases—one for managers and one for staff. Which of the following three-point time estimates would you choose for fully training the team (including planning, training the managers, and training the staff at each location)?
- Optimistic: 2 days; Most Likely: 1 day; Pessimistic: 4 days
- Optimistic: 15 days; Most Likely: 30 days; Pessimistic: 45 days
- Optimistic: 20 days; Most Likely: 14 days; Pessimistic: 10 days
- Optimistic: 10 days; Most Likely: 14 days; Pessimistic: 21 days
3. Which of the following pieces of information should Peta consider when determining the confidence rating for the wiring time estimate? Select all that apply.
- The team is still waiting for the menu update
- The restaurant has attempted table wiring at least once before
- The electrician is confident in the amount of time they need to complete the wiring
- The team’s level of confidence in the time estimate
4. The meeting notes state that Sauce & Spoon has never integrated tablet software with their POS system before and may need to upgrade the system before starting the integration. What confidence rating is appropriate for the POS system time estimates?
5. The meeting notes state that the electrician could complete the wiring for both locations in two business days (or 16 hours). Because the restaurants cannot close for a full day for the upgrade, the team estimates four business days (two half-days at each location) to complete the wiring. Based on this information, what notes could you make to add context for this task in the project plan? Select all that apply.
- “Find money in the budget for an electrician”
- “Contact internet service provider to ensure the network can handle tablet WiFi traffic”
- “Check with electrician on whether mornings or afternoons work better with their schedule”
- “Notify GMs when their locations need to close for wiring”
